Abstract

PROBLEM TO BE SOLVED: To suppress creep deformation around a through-hole when a reinforcing member as a fiber-reinforced composite is arranged in the fastening through-hole formed in a fastened member as a resin molding.SOLUTION: A core thread 2 and a plaited thread 3 as carbon fibers are formed as a braid-like texture. The reinforcing member 1 as a fiber-reinforced composite includes: a cylindrical cylinder portion 5 fixable to the through-hole 4; and an annular first flange portion 6 and an annular second flange portion 7 which are formed radially outward of the through-hole 4 from the upper and lower ends of the cylinder portion 5. The fastened member 10 as a fiber-reinforced composite and a metal material 12 are fastened to each other by a bolt 8. A head 8a of the bolt abuts on the first flange portion 6. On the inner peripheral surface of the through-hole 4, the cylindrical portion 5 is arranged in a region to be brought into contact with the bolt 8 without any gap. In the cylindrical portion 5, the core thread 2 is directed in the axial 4a direction of the through-hole 4 and oriented at least from one opening of the through-hole 4 to the other opening thereof.

Description

本発明は、樹脂成形体である被締結部材に形成された締結用の貫通孔に配置される繊維強化複合材である補強部材及び貫通孔に補強部材が配置された被締結部材の締結構造に関する。   The present invention relates to a reinforcing member that is a fiber-reinforced composite material disposed in a fastening through hole formed in a fastened member that is a resin molded body, and a fastening structure of a fastened member in which the reinforcing member is disposed in the through hole. .

樹脂成形体は軽量の構造材であり、ボルト及びナット等の締結部材により他の部品に取り付けて使用される場合がある。しかし、他の部材に直接取り付けられた樹脂成形体は締結力によりクリープ変形を生じ、締結部材の軸力が低下する。そのために、樹脂成形体と他の部材とを締結した場合、緩みが生じるという問題がある。このような樹脂成形体の取り付け上の問題を解消するため、一般的には、例えば特許文献１に開示されているような金属パイプを用いた取り付け方法が多く用いられている。   The resin molded body is a lightweight structural material and may be used by being attached to other parts by fastening members such as bolts and nuts. However, the resin molding directly attached to the other member undergoes creep deformation due to the fastening force, and the axial force of the fastening member is reduced. Therefore, there is a problem that loosening occurs when the resin molded body and other members are fastened. In order to solve such a problem in the mounting of the resin molded body, generally, for example, a mounting method using a metal pipe as disclosed in Patent Document 1 is often used.

特許文献１には、回転検出装置を備えたハウジングを車載エンジンに取り付けた構造が開示されている。ハウジングは車載エンジンへ取り付けるためのフランジとともに樹脂成形されている。フランジに形成された貫通孔には、金属パイプがインサート成形により挿入され、一体化されている。ハウジングは金属パイプに通したボルトを車載エンジンの雌ネジに締結することにより取り付けられている。   Patent Document 1 discloses a structure in which a housing including a rotation detection device is attached to an in-vehicle engine. The housing is resin-molded with a flange for attachment to an in-vehicle engine. A metal pipe is inserted into and integrated with the through hole formed in the flange by insert molding. The housing is attached by fastening a bolt passed through a metal pipe to a female screw of an in-vehicle engine.

特許文献２には、樹脂をマトリックスとして強化繊維を含有した繊維強化複合材と他の部材との締結構造が開示されている。繊維強化複合材にはボルトが挿入される貫通孔が備えられており、貫通孔の内周面には高弾性率の強化繊維が同心円状に巻きつけられている。   Patent Document 2 discloses a fastening structure of a fiber reinforced composite material containing a reinforcing fiber using a resin as a matrix and another member. The fiber reinforced composite material is provided with a through hole into which a bolt is inserted, and a high elastic modulus reinforcing fiber is wound concentrically around the inner peripheral surface of the through hole.

特許文献３には、板状に形成された弾性体の上下に樹脂層が形成されたサンドイッチ構造板に、締結部材が取り付けられた構造が開示されている。サンドイッチ構造板にはボルトが挿入される貫通孔が形成されており、貫通孔の内周面には繊維強化複合材が取り付けられている。繊維強化複合材はマトリックスである樹脂と、貫通孔の軸方向に対して斜めに配向された強化繊維とで構成されている。繊維強化複合材には、貫通孔の両端から側方に突出したフランジ部が形成されており、ボルト及びナットで締結されたサンドイッチ構造板において、フランジ部はボルトの頭部及びナットと樹脂層に挟まれている。   Patent Document 3 discloses a structure in which a fastening member is attached to a sandwich structure plate in which a resin layer is formed on the top and bottom of an elastic body formed in a plate shape. A through-hole into which a bolt is inserted is formed in the sandwich structure plate, and a fiber reinforced composite material is attached to the inner peripheral surface of the through-hole. The fiber reinforced composite material is composed of a resin that is a matrix and reinforcing fibers that are oriented obliquely with respect to the axial direction of the through holes. The fiber reinforced composite material is formed with flange portions protruding laterally from both ends of the through hole.

特許文献１では、ボルトの締結力は金属パイプにのみ作用し、樹脂材料で成形されたフランジにかからないため、樹脂のクリープによる緩みの問題を解消することができる。 しかし、ボルトが挿入される貫通孔に金属パイプを一体化する方法は金属パイプの高い取り付け精度を必要とする。例えば、金属パイプを前記フランジにインサート成形する場合は、特許文献１の発明のように、金属パイプの端面とボルトの頭部及び車載エンジンとの間に樹脂が介在されないように精度の高い成形技術が必要となる。また、金属パイプを貫通孔に圧入する方法では、貫通孔の精度や金属パイプの圧入精度を高める必要があるため、加工工数が増加し、加工作業も煩雑になる。また、金属パイプの使用は重量増加に繋がり、樹脂材料による軽量化という利点を阻害することにもなる。   In patent document 1, since the fastening force of a bolt acts only on a metal pipe and does not apply to a flange formed of a resin material, the problem of loosening due to resin creep can be solved. However, the method of integrating the metal pipe into the through hole into which the bolt is inserted requires a high mounting accuracy of the metal pipe. For example, when a metal pipe is insert-molded into the flange, as in the invention of Patent Document 1, a high-precision molding technique is performed so that no resin is interposed between the end surface of the metal pipe, the head of the bolt, and the vehicle-mounted engine. Is required. Moreover, in the method of press-fitting a metal pipe into a through hole, it is necessary to increase the accuracy of the through hole and the press-fitting accuracy of the metal pipe, so that the number of processing steps increases and the processing work becomes complicated. In addition, the use of metal pipes leads to an increase in weight, which also hinders the advantage of weight reduction by the resin material.

特許文献２では、貫通孔に挿入されたボルトを締結した場合、貫通孔の内周面に強化繊維が配向されているため、繊維強化複合材の座屈が防止される。しかし、貫通孔の内周面に配向された強化繊維の隙間には樹脂が存在し、強化繊維の隙間の樹脂がクリープすることでボルトが緩むという問題がある。また、強化繊維を密に配置し樹脂の量を少なくした場合には、強化繊維同士が接触して強化繊維の隙間に樹脂が存在しなくなる。このように強化繊維が樹脂を介さずに配置されると、強化繊維同士が接着されない。   In patent document 2, when the bolt inserted in the through hole is fastened, the reinforcing fiber is oriented on the inner peripheral surface of the through hole, so that buckling of the fiber reinforced composite material is prevented. However, there is a problem that resin exists in the gap between the reinforcing fibers oriented on the inner peripheral surface of the through hole, and the bolt loosens due to creep of the resin in the gap between the reinforcing fibers. Further, when the reinforcing fibers are arranged densely and the amount of the resin is reduced, the reinforcing fibers come into contact with each other, and the resin does not exist in the gap between the reinforcing fibers. When the reinforcing fibers are arranged without the resin in this way, the reinforcing fibers are not bonded to each other.

特許文献３では、サンドイッチ構造板の貫通孔に挿入されたボルトを締結した場合、貫通孔の内周面に繊維強化複合材が配置されている。そのため、ボルトの軸力による樹脂層のクリープ変形が抑制される。また、繊維強化複合材で形成されたフランジ部により貫通孔の周囲が補強される。繊維強化複合材が取り付けられたサンドイッチ構造板をボルトで締結した場合、斜めに配向された強化繊維の交差角が広がるために繊維強化複合材が変形され厚みが変化する。特許文献３では繊維強化複合材の厚みをボルトの軸力により変形されたサンドイッチ構造板の厚みと対応させることで、サンドイッチ構造板の締結構造を維持している。そのため、内部に弾性体が存在しないサンドイッチ構造板のような樹脂成形体の貫通孔に特許文献３の繊維強化複合材を適用した場合は、ボルトを締結することによる樹脂成形体の表面のクリープ変形に追随して繊維強化複合材の厚みが減少するという問題がある。   In Patent Document 3, when a bolt inserted into a through hole of a sandwich structure plate is fastened, a fiber reinforced composite material is disposed on the inner peripheral surface of the through hole. Therefore, creep deformation of the resin layer due to the axial force of the bolt is suppressed. Further, the periphery of the through hole is reinforced by the flange portion formed of the fiber reinforced composite material. When the sandwich structure plate to which the fiber reinforced composite material is attached is fastened with bolts, the cross angle of the reinforcing fibers obliquely oriented spreads, so that the fiber reinforced composite material is deformed and the thickness changes. In Patent Document 3, the fastening structure of the sandwich structure plate is maintained by making the thickness of the fiber reinforced composite material correspond to the thickness of the sandwich structure plate deformed by the axial force of the bolt. Therefore, when the fiber reinforced composite material of Patent Document 3 is applied to a through hole of a resin molded body such as a sandwich structure plate in which no elastic body exists, creep deformation of the surface of the resin molded body by fastening a bolt Following this, there is a problem that the thickness of the fiber-reinforced composite material decreases.

本発明は、樹脂成形体である被締結部材に形成された締結用の貫通孔に繊維強化複合材である補強部材が配置される場合において、貫通孔周囲のクリープ変形を抑制することができる。   The present invention can suppress creep deformation around a through hole when a reinforcing member that is a fiber-reinforced composite material is disposed in a fastening through hole formed in a member to be fastened that is a resin molded body.

請求項１に記載の本発明は、締結部材が挿入可能な樹脂成形体である被締結部材の貫通孔の内部に配置される補強部材であり、樹脂をマトリックスとして強化繊維を含有する繊維強化複合材である補強部材において、前記補強部材の少なくとも一部の強化繊維は前記貫通孔の軸方向を向きかつ少なくとも前記貫通孔の一方の開口部から他方の開口部に亘って配向されることを特徴とする。   The present invention according to claim 1 is a reinforcing member disposed inside a through hole of a member to be fastened, which is a resin molded body into which a fastening member can be inserted, and a fiber-reinforced composite containing a reinforcing fiber with a resin as a matrix In the reinforcing member that is a material, at least some of the reinforcing fibers of the reinforcing member are oriented in the axial direction of the through hole and from at least one opening portion of the through hole to the other opening portion. And

請求項１に記載の本発明によれば、少なくとも一部の強化繊維が貫通孔の軸方向を向きかつ少なくとも貫通孔の一方の開口部から他方の開口部に亘って配向された場合において、補強部材の圧縮弾性率を被締結部材の樹脂の圧縮弾性率よりも大きくすることができる。そのため、貫通孔に締結部材が挿入されて被締結部材が他の部材と締結された場合において、被締結部材の貫通孔周囲におけるクリープ変形を抑制することができる。   According to the first aspect of the present invention, in the case where at least some of the reinforcing fibers are oriented in the axial direction of the through hole and at least oriented from one opening to the other opening of the through hole, the reinforcement The compression elastic modulus of the member can be made larger than the compression elastic modulus of the resin of the member to be fastened. Therefore, when the fastening member is inserted into the through hole and the fastened member is fastened to another member, creep deformation around the through hole of the fastened member can be suppressed.

なお、補強部材が貫通孔の内部に配置されるとは、少なくとも一部の補強部材が貫通孔の内部において貫通孔の内周面に隙間なく密着している場合に加え、補強部材と貫通孔の内周面との間に隙間が存在し、隙間を介して少なくとも一部の補強部材が貫通孔の内部に配置される場合を含む。   Note that the reinforcing member is disposed inside the through hole means that at least a part of the reinforcing member is in close contact with the inner peripheral surface of the through hole inside the through hole without any gap. This includes a case where a gap exists between the inner peripheral surface and at least a part of the reinforcing member is disposed inside the through hole via the gap.

また、強化繊維が真っ直ぐな形状である場合においての、強化繊維が貫通孔の軸方向を向いて配向されるとは、強化繊維が貫通孔の軸と平行に配向される場合に加え、強化繊維の配向方向（繊維軸の方向）が貫通孔の軸（応力軸）に対して少しずれた方向を向いている場合を含む。繊維軸と応力軸のなす角度が０°である場合、強化繊維が含有された繊維強化複合材の圧縮弾性率は最大になる。繊維軸と応力軸のなす角度が小さければ、繊維強化複合材の圧縮弾性率は最大に近い。例えば、繊維軸と応力軸のなす角度が０°の場合における繊維強化複合材の圧縮弾性率を１００％としたとき、繊維軸と応力軸のなす角度が１０°の場合における繊維強化複合材の圧縮弾性率は８０％である。そのため、好ましくは強化繊維の配向方向と貫通孔の軸とのなす角度は１０°以内である。   Further, in the case where the reinforcing fiber has a straight shape, the reinforcing fiber is oriented in the axial direction of the through hole, in addition to the case where the reinforcing fiber is oriented parallel to the axis of the through hole. This includes the case where the orientation direction of the fiber (the direction of the fiber axis) faces a direction slightly shifted from the axis of the through hole (stress axis). When the angle formed by the fiber axis and the stress axis is 0 °, the compression elastic modulus of the fiber-reinforced composite material containing the reinforcing fibers is maximized. If the angle formed by the fiber axis and the stress axis is small, the compression elastic modulus of the fiber-reinforced composite material is close to the maximum. For example, when the compression modulus of the fiber reinforced composite material when the angle between the fiber axis and the stress axis is 0 ° is 100%, the fiber reinforced composite material when the angle between the fiber axis and the stress axis is 10 °. The compression modulus is 80%. Therefore, the angle formed by the orientation direction of the reinforcing fiber and the axis of the through hole is preferably within 10 °.

また、束状の強化繊維が組紐状あるいは織物状等に形成される際に、束状の強化繊維同士が接触される箇所に強化繊維に曲がる、折れる等の変形が生じる場合において、強化繊維が貫通孔の軸方向を向いて配向されるとは、強化繊維の長手方向（繊維軸の方向）が貫通孔の軸と平行に配向される場合に加え、強化繊維の長手方向が貫通孔の軸に対して少しずれた方向を向いている場合を含む。好ましくは強化繊維の長手方向と貫通孔の軸とのなす角度は１０°以内である。   In addition, when the bundle-like reinforcing fibers are formed in a braided shape or a woven shape, the reinforcing fibers may be bent when the bundle-like reinforcing fibers are in contact with each other. “Oriented in the axial direction of the through-hole” means that the longitudinal direction of the reinforcing fiber is oriented parallel to the axis of the through-hole, and the longitudinal direction of the reinforcing fiber is the axis of the through-hole. Including the case where the direction is slightly deviated from Preferably, the angle formed by the longitudinal direction of the reinforcing fiber and the axis of the through hole is within 10 °.

なお、補強部材の少なくとも一部の強化繊維が少なくとも貫通孔の一方の開口部から他方の開口部に亘って配向されるとは、強化繊維が貫通孔の軸方向に隙間なく配向されることを指し、貫通孔の軸方向の長さより短い強化繊維が貫通孔の軸方向に配向されており、貫通孔の両開口部の間に強化繊維が配向されない領域（隙間）が生じる場合を除く。   Note that the fact that at least a part of the reinforcing fibers of the reinforcing member is oriented at least from one opening of the through hole to the other opening means that the reinforcing fibers are oriented without gaps in the axial direction of the through hole. This refers to the case where the reinforcing fibers shorter than the length of the through hole in the axial direction are oriented in the axial direction of the through hole, and a region (gap) where the reinforcing fibers are not oriented is formed between both openings of the through hole.

請求項２に記載の本発明は、前記被締結部材は繊維強化複合材であることを特徴とする。前記補強部材が配置される被締結部材は強化繊維を含有するため、被締結部材においてクリープの原因である樹脂の量が減少する。そのため、被締結部材が強化繊維を含有しない場合と比べて被締結部材のクリープ抑制効果を高めることができる。   The present invention according to claim 2 is characterized in that the member to be fastened is a fiber reinforced composite material. Since the fastened member in which the reinforcing member is disposed contains reinforcing fibers, the amount of resin that causes creep in the fastened member is reduced. Therefore, the creep suppressing effect of the fastened member can be enhanced as compared with the case where the fastened member does not contain reinforcing fibers.

請求項３に記載の本発明は、前記強化繊維は組紐状組織に形成されることを特徴とする。よって、強化繊維を円筒形状に継ぎ目なく形成できるため、補強部材を貫通孔の内部に密着させられる。   The present invention according to claim 3 is characterized in that the reinforcing fibers are formed in a braided structure. Therefore, since the reinforcing fiber can be seamlessly formed in a cylindrical shape, the reinforcing member can be brought into close contact with the inside of the through hole.

請求項４に記載の本発明は、前記補強部材は前記貫通孔の少なくとも一方の開口部から前記貫通孔の半径方向外方に突出して設けられかつ前記締結部材と前記被締結部材に挟まれるフランジ部を有することを特徴とする。そのため、フランジ部により締結部材の応力を分散させることができ、貫通孔の内部に配置された補強部材と被締結部材の間に生じる割れや亀裂が防止される。   According to a fourth aspect of the present invention, the reinforcing member is provided so as to protrude radially outward of the through hole from at least one opening of the through hole and is sandwiched between the fastening member and the fastened member It has the part. Therefore, the stress of a fastening member can be disperse | distributed by a flange part, and the crack and crack which arise between the reinforcement member arrange | positioned inside a through-hole and a to-be-fastened member are prevented.

請求項５に記載の本発明は、締結部材と、前記締結部材が挿入可能な貫通孔を有する樹脂成形体である被締結部材と、樹脂をマトリックスとして強化繊維を含有する繊維強化複合材である補強部材と、前記被締結部材と締結される他の部材とからなり、前記締結部材により前記被締結部材が前記他の部材に締結される被締結部材の締結構造において、前記補強部材は前記貫通孔の内部に配置され、前記補強部材の少なくとも一部の前記強化繊維は前記貫通孔の軸方向を向きかつ少なくとも前記貫通孔の一方の開口部から他方の開口部に亘って配向されることを特徴とする。そのため、被締結部材を他の部材と締結する際の、締結部材の緩みを抑制することができる。   The present invention according to claim 5 is a fiber reinforced composite material containing a fastening member, a fastened member that is a resin molded body having a through-hole into which the fastening member can be inserted, and a reinforcing fiber using resin as a matrix. The fastening member includes a reinforcing member and another member fastened to the fastened member, and the fastening member is fastened to the other member by the fastening member. The reinforcing fiber is disposed inside the hole, and the reinforcing fibers of at least a part of the reinforcing member are oriented in the axial direction of the through hole and from at least one opening portion of the through hole to the other opening portion. Features. Therefore, loosening of the fastening member when fastening the fastened member with another member can be suppressed.

本発明は、樹脂成形体である被締結部材に形成された締結用の貫通孔に繊維強化複合材である補強部材が配置される場合において、貫通孔周囲のクリープ変形を抑制することができる。   The present invention can suppress creep deformation around a through hole when a reinforcing member that is a fiber-reinforced composite material is disposed in a fastening through hole formed in a member to be fastened that is a resin molded body.

次に、補強部材１及び被締結部材１０の製造方法を説明する。
束状の炭素繊維である炭素繊維束１１を準備する。平板状の支持体において、支持体の所定の位置にボルト８の軸が挿入可能な径であるパイプを支持体のなす平面に対し垂直な方向（Ｚ軸方向）に立てて配置する。支持体内に所定のピッチでピンを支持体のなす平面に対し垂直な方向（Ｚ軸方向）に立てて配置する。パイプの設けられた領域を除いて、ピンに直交するＸ，Ｙ軸方向に炭素繊維束１１を折り返し状に配列し、炭素繊維束１１が層状に形成された強化繊維層を形成する。 Next, the manufacturing method of the reinforcement member 1 and the to-be-fastened member 10 is demonstrated.
A carbon fiber bundle 11 that is a bundle of carbon fibers is prepared. In a flat support, a pipe having a diameter into which the shaft of the bolt 8 can be inserted is placed at a predetermined position of the support in a direction perpendicular to the plane formed by the support (Z-axis direction). The pins are arranged upright in the support body at a predetermined pitch in a direction (Z-axis direction) perpendicular to the plane formed by the support body. Except for the region where the pipe is provided, the carbon fiber bundles 11 are arranged in a folded manner in the X and Y axis directions orthogonal to the pins, thereby forming a reinforcing fiber layer in which the carbon fiber bundles 11 are formed in layers.

次に、強化繊維層を積層してＸ，Ｙの２軸配向となる積層糸群を形成する。支持体内のピンを取り除き、積層糸群をなす各糸層と直交する方向（Ｚ軸方向）に配列される厚さ方向糸（垂直糸）と置換する。積層糸群を厚さ方向糸で結合する。支持体内のパイプを取り除き、互いに直交するＸ，Ｙ及びＺ軸方向にそれぞれ伸びる炭素繊維束１１からなる三次元繊維組織を形成する。なお、三次元繊維組織とは被締結部材１０においてマトリックスである樹脂が含浸される前の三次元構造の炭素繊維束１１である。三次元繊維組織にはパイプが取り除かれた領域に、貫通孔４が形成される。   Next, the reinforcing fiber layer is laminated to form a laminated yarn group having X and Y biaxial orientation. The pins in the support body are removed and replaced with thickness direction yarns (vertical yarns) arranged in a direction (Z-axis direction) perpendicular to each yarn layer forming the laminated yarn group. The laminated yarn group is joined with a thickness direction yarn. The pipe in the support body is removed, and a three-dimensional fiber structure composed of carbon fiber bundles 11 extending in the X, Y, and Z axis directions orthogonal to each other is formed. The three-dimensional fiber structure is the carbon fiber bundle 11 having a three-dimensional structure before the fastened member 10 is impregnated with the resin as a matrix. In the three-dimensional fiber structure, a through hole 4 is formed in a region where the pipe is removed.

束状の炭素繊維からなる芯糸２及び組糸３を準備する。断面がボルト８の軸心を挿入可能な径である円柱の芯材を用意する。組紐状組織を形成する装置である三次元ブレーダー（ロータ・キャリア方式三次元織物織機）の中心（形成する組紐状組織の軸心）に芯材を配置した状態で、芯材の外周部に補強部材１を構成する組紐状組織を形成する。なお、組紐状組織とは補強部材１においてマトリックスである樹脂が含浸される前の芯糸２及び組糸３からなる集合体である。芯材の軸方向（Ｚ軸方向）に向いて芯糸２を配列し、Ａ，Ｂの２軸方向に組糸３を配列する。ここでＡ，Ｂ軸は芯糸２の方向（Ｚ軸方向）に対して斜めでありかつ、Ａ軸とＢ軸が交わる方向である。   A core yarn 2 and a braided yarn 3 made of bundled carbon fibers are prepared. A cylindrical core member having a cross section with a diameter capable of inserting the axis of the bolt 8 is prepared. Reinforce the outer periphery of the core material with the core material placed at the center (axis of the braided tissue structure to be formed) of the 3D braider (rotor carrier type 3D weaving loom), which is a device for forming the braided texture. A braided tissue constituting the member 1 is formed. The braided structure is an aggregate composed of the core yarn 2 and the braid 3 before the reinforcing member 1 is impregnated with the resin as the matrix. The core yarn 2 is arranged in the axial direction (Z-axis direction) of the core material, and the braided yarn 3 is arranged in the two axial directions of A and B. Here, the A and B axes are oblique to the direction of the core yarn 2 (Z-axis direction) and are directions in which the A axis and the B axis intersect.

三次元ブレーダーにより、芯糸２をＺ軸方向に保持しつつ芯糸２と組糸３を組み合せて組紐状組織を形成する。組紐状組織はＺ軸方向の長さが貫通孔４の高さに対応した長さに形成される。組紐状組織の外周が貫通孔４の内周に対応する形状に組紐状組織を形成する。組紐状組織から芯材を取り除き、円筒状の組紐状組織である組紐円筒部を得る。なお、組紐円筒部は補強部材１における円筒部５に対応しており、マトリックスである樹脂が含浸される前の組紐状に形成された炭素繊維である。   A braided structure is formed by combining the core yarn 2 and the braid 3 while holding the core yarn 2 in the Z-axis direction by a three-dimensional braider. The braided tissue is formed such that the length in the Z-axis direction corresponds to the height of the through hole 4. The braided tissue is formed in a shape in which the outer periphery of the braided tissue corresponds to the inner periphery of the through hole 4. The core material is removed from the braided tissue to obtain a braided cylindrical portion which is a cylindrical braided tissue. The braided cylindrical portion corresponds to the cylindrical portion 5 in the reinforcing member 1 and is a carbon fiber formed in a braided shape before being impregnated with a resin that is a matrix.

組紐円筒部の上端及び下端部に、円環状の組紐状組織である組紐フランジ部を組紐円筒部と連続して形成する。なお、組紐フランジ部とは補強部材１における第１フランジ部６及び第２フランジ部７に対応しており、マトリックスである樹脂が含浸される前の組紐状に形成された炭素繊維である。組紐フランジ部は、組紐円筒部の上端及び下端から連続した芯糸２及び組糸３を組み合せて、組紐円筒部と連続して形成される。   A braided flange portion, which is an annular braided structure, is formed on the upper and lower ends of the braided cylindrical portion continuously with the braided cylindrical portion. The braid flange portion corresponds to the first flange portion 6 and the second flange portion 7 in the reinforcing member 1 and is a carbon fiber formed in a braid shape before being impregnated with a resin as a matrix. The braided flange portion is formed continuously with the braided cylindrical portion by combining the core yarn 2 and the braided yarn 3 continuous from the upper end and the lower end of the braided cylindrical portion.

三次元繊維組織の貫通孔４に組紐状組織を挿入し、組紐状組織の端部を三次元繊維組織の貫通孔４から突出させて配置する。挿入の際に、組紐フランジ部は貫通孔４の径を通過可能に折り曲げられている。挿入により組紐円筒部が貫通孔４の内周面に対応して配置され、組紐フランジ部が三次元繊維組織における貫通孔４の上端及び下端に配置される。組紐フランジ部は貫通孔４の上端及び下端において、元の形状（円環状）に広げられる。組紐フランジ部は全ての領域で三次元繊維組織と接して配置される。   A braided tissue is inserted into the through-hole 4 of the three-dimensional fiber structure, and an end of the braided tissue is protruded from the through-hole 4 of the three-dimensional fiber structure. At the time of insertion, the braided flange portion is bent so as to pass through the diameter of the through hole 4. By insertion, the braided cylindrical portion is arranged corresponding to the inner peripheral surface of the through-hole 4, and the braided flange portion is arranged at the upper and lower ends of the through-hole 4 in the three-dimensional fiber structure. The braided flange portion is expanded to the original shape (annular shape) at the upper end and the lower end of the through hole 4. The braid flange portion is arranged in contact with the three-dimensional fiber structure in all regions.

三次元繊維組織に固定された組紐状組織は成形型を用いて成形体に成形される。成形型は上型と下型からなり、型締め状態において型内を減圧にする減圧通路と、型内に樹脂を注入する樹脂注入通路とを備えている。下型には組紐状組織の組紐円筒部の内径に対応する断面である円柱状の凸部が形成されている。上型が開かれた状態で、組紐円筒部が凸部を囲繞しかつ凸部と接するように、組紐状組織を下型に配置する。次に上型を閉じて型内を真空に近い状態まで減圧した状態で、マトリックスとしての熱硬化性樹脂を型内に注入し、三次元繊維組織及び組紐状組織に含浸する。
次に成形型を図示しない加熱手段によって三次元繊維組織及び組紐状組織を樹脂の熱硬化温度以上に加熱し、含浸した樹脂を硬化する。成形型の温度が低下した後に成形型を開き、樹脂が硬化した成形体を下型から取り出す。なお、成形体は三次元繊維組織及び組紐状組織並びにマトリックスとしての樹脂からなる繊維強化複合材であり、被締結部材１０及び補強部材１が一体に形成されたものである。 The braided structure fixed to the three-dimensional fiber structure is formed into a formed body using a forming die. The mold includes an upper mold and a lower mold, and includes a pressure reducing passage for reducing the pressure in the mold in a clamped state and a resin injection passage for injecting resin into the mold. A columnar convex portion having a cross section corresponding to the inner diameter of the braided cylindrical portion of the braided tissue is formed on the lower mold. In a state where the upper mold is opened, the braided tissue is arranged on the lower mold so that the braided cylindrical part surrounds the convex part and is in contact with the convex part. Next, in a state where the upper die is closed and the inside of the die is decompressed to a state close to vacuum, a thermosetting resin as a matrix is injected into the die and impregnated into a three-dimensional fiber structure and braided structure.
Next, the three-dimensional fiber structure and the braided structure are heated to a temperature equal to or higher than the thermosetting temperature of the resin by heating means (not shown) to cure the impregnated resin. After the temperature of the mold is lowered, the mold is opened, and the molded body in which the resin is cured is taken out from the lower mold. In addition, a molded object is a fiber reinforced composite material which consists of resin as a three-dimensional fiber structure and braided structure | tissue, and a matrix, and the to-be-fastened member 10 and the reinforcement member 1 are integrally formed.

第１の実施形態における補強部材１及び被締結部材１０の作用を説明する。
被締結部材１０における貫通孔４の内周面に補強部材１が固定されており、補強部材１において芯糸２が貫通孔４の軸４ａ方向（被締結部材１０の板厚方向）を向いてかつ少なくとも貫通孔４の一方の開口部から他方の開口部に亘って連続して配向されており、芯糸２はボルト８の頭部８ａ及び金属材１２と当接している。芯糸２の配向方向は被締結部材１０に応力がかかる方向である。すなわち繊維軸と応力軸のなす角度は０°である。被締結部材１０の貫通孔４にボルト８が挿入されて、被締結部材１０が金属材１２と締結された場合、ボルト８の締結による軸力は貫通孔４の内周面において、貫通孔４の軸４ａ方向を向いて配向された炭素繊維である芯糸２に分担される。被締結部材１０のマトリックスである熱硬化性樹脂の圧縮弾性率に比べ、補強部材１において、芯糸２が貫通孔４の軸４ａ方向に配向された場合（繊維軸と応力軸のなす角度が０°である場合）の圧縮弾性率は４０倍程度大きい。そのため、ボルト８の締結力による被締結部材１０のマトリックスである樹脂のクリープが抑制され、被締結部材１０の変形を防ぐことができる。 The operation of the reinforcing member 1 and the fastened member 10 in the first embodiment will be described.
The reinforcing member 1 is fixed to the inner peripheral surface of the through hole 4 in the fastened member 10, and the core yarn 2 faces the direction of the axis 4 a of the through hole 4 (the plate thickness direction of the fastened member 10) in the reinforcing member 1. In addition, the core yarn 2 is continuously oriented from at least one opening portion of the through hole 4 to the other opening portion, and the core yarn 2 is in contact with the head 8 a of the bolt 8 and the metal material 12. The orientation direction of the core yarn 2 is a direction in which stress is applied to the fastened member 10. That is, the angle formed by the fiber axis and the stress axis is 0 °. When the bolt 8 is inserted into the through hole 4 of the fastened member 10 and the fastened member 10 is fastened to the metal material 12, the axial force due to the fastening of the bolt 8 is generated in the through hole 4 on the inner peripheral surface of the through hole 4. The core yarn 2 is a carbon fiber oriented in the direction of the axis 4a. When the core yarn 2 is oriented in the direction of the axis 4a of the through hole 4 in the reinforcing member 1 as compared with the compression elastic modulus of the thermosetting resin that is the matrix of the fastened member 10 (the angle between the fiber axis and the stress axis is The compression elastic modulus (when it is 0 °) is about 40 times larger. Therefore, the creep of the resin that is the matrix of the fastened member 10 due to the fastening force of the bolt 8 is suppressed, and deformation of the fastened member 10 can be prevented.

被締結部材１０において主にクリープを生じるのは、被締結部材１０がボルト８と当接された領域（ボルトの頭部８ａと当接する領域及び貫通孔４の内部）である。被締結部材１０の板厚が十分薄い場合、被締結部材１０においてボルト８の頭部８ａと当接する任意の点における応力と、貫通孔４の内部における任意の点における応力は同等である。そのため、少なくとも貫通孔４の内部に芯糸２が貫通孔４の軸４ａ方向を向いて配向されていれば、被締結部材１０がボルト８の頭部８ａと当接された領域に芯糸２が配向されない場合であっても、貫通孔４の内部にかかるボルト８の応力を芯糸２が分担することで、貫通孔４の内部の被締結部材１０への応力集中が低減される。   In the fastened member 10, creep mainly occurs in the region where the fastened member 10 is in contact with the bolt 8 (the region in contact with the bolt head 8 a and the inside of the through hole 4). When the plate thickness of the fastened member 10 is sufficiently thin, the stress at an arbitrary point in contact with the head portion 8a of the bolt 8 in the fastened member 10 and the stress at an arbitrary point inside the through hole 4 are equal. Therefore, if the core yarn 2 is oriented at least inside the through hole 4 so as to face the direction of the axis 4 a of the through hole 4, the core yarn 2 is in the region where the fastened member 10 is in contact with the head 8 a of the bolt 8. Is not oriented, the core yarn 2 shares the stress of the bolt 8 applied to the inside of the through hole 4, thereby reducing the stress concentration on the fastened member 10 inside the through hole 4.

被締結部材１０はマトリックスとしての樹脂に加え、炭素繊維束１１を含有する。被締結部材１０は炭素繊維束１１を含有しない場合に比べてクリープの原因である樹脂の量が少ない。そのため、補強部材１が締結される被締結部材として被締結部材１０を用いることで、クリープを抑制する効果を高められる。   The fastened member 10 contains a carbon fiber bundle 11 in addition to a resin as a matrix. The member 10 to be fastened has a smaller amount of resin that causes creep than the case where the carbon fiber bundle 11 is not contained. Therefore, the effect of suppressing creep can be enhanced by using the fastened member 10 as the fastened member to which the reinforcing member 1 is fastened.

貫通孔４の内部に補強部材１を隙間なく密着させるためには、補強部材１における円筒部５の外周を円形に形成する必要がある。反物状の織物に形成された炭素繊維を筒状に形成する場合、織物の端部を縫い合わせて接合する必要があり、継ぎ目が生じる。これに対し、炭素繊維である芯糸２及び組糸３からなる組紐状組織により炭素繊維を筒状に形成する場合では、端部を接合する必要がないため、補強部材１を継ぎ目のない円筒状に形成することができる。従って、補強部材１を貫通孔４の内部に隙間なく密着させることが可能となる。   In order to closely attach the reinforcing member 1 to the inside of the through hole 4 without a gap, it is necessary to form the outer periphery of the cylindrical portion 5 of the reinforcing member 1 in a circular shape. When carbon fibers formed on a fabric-like fabric are formed into a cylindrical shape, the ends of the fabric need to be sewn and joined, resulting in a seam. On the other hand, in the case where the carbon fiber is formed in a tubular shape by the braided structure composed of the core yarn 2 and the braid 3 that are carbon fibers, it is not necessary to join the end portions, so that the reinforcing member 1 is a seamless cylinder. Can be formed. Therefore, the reinforcing member 1 can be brought into close contact with the inside of the through hole 4 without a gap.

また、組紐状組織により補強部材１を形成することで、補強部材１の円筒部５と第１フランジ部６及び第２フランジ部７とを連続して形成することができる。   Moreover, the cylindrical part 5 of the reinforcement member 1, the 1st flange part 6, and the 2nd flange part 7 can be continuously formed by forming the reinforcement member 1 with a braided structure | tissue.

クリープ抑制効果を高めるには、貫通孔４の内部を含む領域において、少なくとも一部の炭素繊維が貫通孔４の軸４ａ方向を向いて配向される必要がある。そのため、炭素繊維の向きを安定して配置できることが望ましい。炭素繊維である芯糸２及び組糸３を組み上げて組紐状組織が形成される場合では、芯糸２は芯糸２に対して斜めに配向された組糸３により固定されるので、芯糸２の位置及び方向を安定させることができる。従って、補強部材１において芯糸２を貫通孔４の軸４ａ方向に安定して配置することができ、被締結部材１０のクリープ抑制効果を高めることができる。   In order to enhance the creep suppressing effect, at least a part of the carbon fibers needs to be oriented in the direction of the axis 4 a of the through hole 4 in the region including the inside of the through hole 4. Therefore, it is desirable that the orientation of the carbon fiber can be stably arranged. In the case where a braided structure is formed by assembling the core yarn 2 and the braid 3 that are carbon fibers, the core yarn 2 is fixed by the braid 3 that is obliquely oriented with respect to the core yarn 2. The position and direction of 2 can be stabilized. Accordingly, the core yarn 2 can be stably arranged in the direction of the axis 4a of the through hole 4 in the reinforcing member 1, and the creep suppressing effect of the fastened member 10 can be enhanced.

強化繊維の向きが異なる繊維強化複合材を接合した場合や、樹脂と繊維強化複合材を接合した場合には、接合部である界面において層間剥離が生じる。被締結部材１０の貫通孔４の内周面に補強部材１の円筒部５が固定された場合、被締結部材１０と補強部材１との界面に応力が集中してかかると亀裂が生じる恐れがある。補強部材１は第１フランジ部６及び第２フランジ部７を有するため、被締結部材１０と補強部材１との界面は第１フランジ部６及び第２フランジ部７に覆われる。従って、ボルト８の頭部８ａからの応力は界面に直接かからず第１フランジ部６及び第２フランジ部７により分散される。そのため、補強部材１と被締結部材１０の間に生じる割れや亀裂を防止することができる。   When fiber reinforced composite materials having different reinforcing fiber orientations are joined, or when a resin and fiber reinforced composite materials are joined, delamination occurs at the interface that is the joint. When the cylindrical portion 5 of the reinforcing member 1 is fixed to the inner peripheral surface of the through-hole 4 of the fastened member 10, there is a risk that cracks may occur if stress is concentrated on the interface between the fastened member 10 and the reinforcing member 1. is there. Since the reinforcing member 1 has the first flange portion 6 and the second flange portion 7, the interface between the fastened member 10 and the reinforcing member 1 is covered with the first flange portion 6 and the second flange portion 7. Therefore, the stress from the head 8 a of the bolt 8 is not applied directly to the interface but is distributed by the first flange portion 6 and the second flange portion 7. Therefore, the crack and crack which arise between the reinforcing member 1 and the to-be-fastened member 10 can be prevented.

被締結部材１０の貫通孔４の内周面に補強部材１が固定されており、貫通孔４に挿入されたボルト８により被締結部材１０が金属材１２と締結されている。貫通孔４の内周面に補強部材１が固定されているため、被締結部材１０と金属材１２をボルト８により締結する場合において、ボルト８の緩みを抑制することができる。   The reinforcing member 1 is fixed to the inner peripheral surface of the through hole 4 of the fastened member 10, and the fastened member 10 is fastened to the metal material 12 by a bolt 8 inserted into the through hole 4. Since the reinforcing member 1 is fixed to the inner peripheral surface of the through hole 4, loosening of the bolt 8 can be suppressed when the fastened member 10 and the metal material 12 are fastened by the bolt 8.

補強部材１における円筒部５の上端及び下端に第１フランジ部６及び第２フランジ部７が設けられる場合、成形後の補強部材１を被締結部材１０の貫通孔４に嵌め込むことができない。これに対し、第１の実施形態では三次元繊維組織に組紐状組織が組み合された後に樹脂を含浸することで補強部材１と被締結部材１０を一体形成するため、第１フランジ部６及び第２フランジ部７が設けられた補強部材１を被締結部材１０の貫通孔４に固定することができる。
さらに、補強部材１を被締結部材１０の貫通孔４に圧入する必要がないため、被締結部材１０に形成される貫通孔４の加工精度や補強部材１の圧入精度を高めなくてもよく加工が容易になる。 When the 1st flange part 6 and the 2nd flange part 7 are provided in the upper end and lower end of the cylindrical part 5 in the reinforcement member 1, the reinforcement member 1 after shaping | molding cannot be fitted in the through-hole 4 of the to-be-fastened member 10. FIG. In contrast, in the first embodiment, the reinforcing member 1 and the fastened member 10 are integrally formed by impregnating the resin after the braided structure is combined with the three-dimensional fiber structure. The reinforcing member 1 provided with the second flange portion 7 can be fixed to the through hole 4 of the fastened member 10.
Furthermore, since it is not necessary to press-fit the reinforcing member 1 into the through-hole 4 of the fastened member 10, the processing accuracy of the through-hole 4 formed in the fastened member 10 and the press-fit accuracy of the reinforcing member 1 need not be increased. Becomes easier.

補強部材１はマトリックスとしての樹脂と炭素繊維とからなり、金属製の部材ではない。そのため、特許文献１のように金属パイプを取り付ける場合に生じる、締結構造における重量の増加を防ぐことができる。また、貫通孔４に金属製の別部材を一体化する場合には、精度の高い成形技術が必要となるが、補強部材１を用いた締結構造では、金属製の別部材を一体化する場合と比べて成形が容易である。
また、補強部材１が固定された被締結部材１０においては、被締結部材１０を廃棄する際に被締結部材１０とインサートされた金属製の別部材とを分離する必要がないため、リサイクル時にかかるコストを低減できる。 The reinforcing member 1 is made of resin and carbon fiber as a matrix, and is not a metal member. Therefore, the increase in the weight in a fastening structure which arises when attaching a metal pipe like patent document 1 can be prevented. In addition, when a separate metal member is integrated into the through-hole 4, a highly accurate molding technique is required. However, in the fastening structure using the reinforcing member 1, a separate metal member is integrated. Compared with, it is easy to mold.
Further, in the fastened member 10 to which the reinforcing member 1 is fixed, it is not necessary to separate the fastened member 10 from the inserted metal member when the fastened member 10 is discarded. Cost can be reduced.

被締結部材１０は、補強部材１の円筒部５に対応した断面形状の円柱である凸部を有する成形型により成形される。成形型に樹脂を注入した場合、成形型の凸部には樹脂が回らないため、被締結部材１０の凸部に対応する領域には成形の段階で締結用の貫通孔４が形成されている。そのため、成形後の被締結部材１０に締結用の貫通孔４を形成する必要がなく、被締結部材１０に工具で貫通孔４を形成する場合に、工具の刃具が痛む恐れがない。   The fastened member 10 is formed by a forming die having a convex portion which is a column having a cross-sectional shape corresponding to the cylindrical portion 5 of the reinforcing member 1. When the resin is injected into the molding die, the resin does not turn to the convex portion of the molding die, so that a fastening through hole 4 is formed in the region corresponding to the convex portion of the fastened member 10 at the molding stage. . Therefore, it is not necessary to form the fastening through hole 4 in the to-be-fastened member 10 after molding, and when the through hole 4 is formed in the to-be-fastened member 10 with a tool, there is no fear that the tool blade is damaged.

前記した第１の実施形態は以下の作用効果を有する。
（１）ボルト８が挿入される貫通孔４を有し被締結部材１０のマトリックスとしての熱硬化性樹脂よりも圧縮弾性率が大きい補強部材１は被締結部材１０の貫通孔４の内周面に固定され、貫通孔４の内周面において芯糸２は貫通孔４の軸４ａ方向を向きかつ少なくとも貫通孔４の一方の開口部から他方の開口部に亘って連続して配向されている。貫通孔４の軸４ａ方向を向いて芯糸２が配向された場合における補強部材１の弾性率は熱硬化性樹脂よりも大きいため、貫通孔４にボルト８が挿入されて被締結部材１０が金属材１２と締結された場合において、ボルト８の応力による被締結部材１０のクリープ変形を抑制することができる。 The first embodiment described above has the following operational effects.
(1) The reinforcing member 1 having the through holes 4 into which the bolts 8 are inserted and having a higher compression elastic modulus than the thermosetting resin as the matrix of the fastened members 10 is the inner peripheral surface of the through holes 4 of the fastened members 10 The core yarn 2 is oriented in the direction of the axis 4a of the through hole 4 and continuously oriented from at least one opening to the other opening of the through hole 4 on the inner peripheral surface of the through hole 4. . Since the elastic modulus of the reinforcing member 1 when the core yarn 2 is oriented in the direction of the axis 4a of the through hole 4 is larger than that of the thermosetting resin, the bolt 8 is inserted into the through hole 4 and the fastened member 10 is When fastened to the metal material 12, creep deformation of the fastened member 10 due to the stress of the bolt 8 can be suppressed.

（２）被締結部材１０は炭素繊維である炭素繊維束１１を含有するので、炭素繊維束１１を含有しない被締結部材と比べてクリープの原因である樹脂の量が少ない。そのため、被締結部材１０のクリープ抑制効果を高めることができる。 (2) Since the fastened member 10 contains the carbon fiber bundle 11 that is carbon fiber, the amount of the resin that causes creep is smaller than that of the fastened member that does not contain the carbon fiber bundle 11. Therefore, the creep suppressing effect of the fastened member 10 can be enhanced.

（３）炭素繊維である芯糸２及び組糸３は組紐状組織に形成されるため、炭素繊維を円筒形状に継ぎ目なく形成でき、補強部材１を貫通孔４の内部に密着させられる。 (3) Since the core yarn 2 and the braid 3 that are carbon fibers are formed in a braided structure, the carbon fibers can be seamlessly formed in a cylindrical shape, and the reinforcing member 1 can be brought into close contact with the inside of the through hole 4.

（４）補強部材１は芯糸２及び組糸３からなる組紐状組織により形成されている。従って、補強部材１において芯糸２を貫通孔４の軸４ａ方向に安定して配向することができ、被締結部材１０のクリープ抑制効果を高めることができる。 (4) The reinforcing member 1 is formed of a braided structure composed of the core yarn 2 and the braided yarn 3. Accordingly, the core yarn 2 can be stably oriented in the direction of the axis 4a of the through hole 4 in the reinforcing member 1, and the creep suppressing effect of the fastened member 10 can be enhanced.

（５）被締結部材１０の貫通孔４に補強部材１を介してボルト８が挿入されることで被締結部材１０を金属材１２と締結されているため、被締結部材１０を金属材１２と締結する際の、ボルト８の緩みを抑制することができる。 (5) Since the bolt 8 is inserted into the through hole 4 of the fastened member 10 via the reinforcing member 1, the fastened member 10 is fastened to the metal material 12. The looseness of the bolt 8 at the time of fastening can be suppressed.

（６）被締結部材１０の貫通孔４に補強部材１を固定するため、貫通孔４に金属製の部材を取り付けた場合に生じる、重量の増加を防ぐことができる。 (6) Since the reinforcing member 1 is fixed to the through hole 4 of the fastened member 10, an increase in weight that occurs when a metal member is attached to the through hole 4 can be prevented.

（７）貫通孔４に金属材１２のような金属製の別部材を一体化する場合には、精度の高い成形技術が必要となるが、補強部材１を用いた締結構造では、金属製の別部材を一体化する場合と比べて成形が容易である。 (7) When a separate metal member such as the metal material 12 is integrated into the through-hole 4, a highly accurate forming technique is required. However, in the fastening structure using the reinforcing member 1, Molding is easier than when separate members are integrated.

（８）補強部材１が固定された被締結部材１０においては、被締結部材１０を廃棄する際に被締結部材１０とインサートされた金属製の別部材とを分離する必要がないため、リサイクル時にかかるコストを低減できる。 (8) In the fastened member 10 to which the reinforcing member 1 is fixed, it is not necessary to separate the fastened member 10 from the inserted metal member when the fastened member 10 is discarded. Such costs can be reduced.

（１０）補強部材１は被締結部材１０と一体成形されている。そのため、補強部材１を被締結部材１０に圧入する必要がなく、被締結部材１０に形成される貫通孔４の加工精度や補強部材１の圧入精度を高めなくてもよい。 (10) The reinforcing member 1 is integrally formed with the fastened member 10. Therefore, it is not necessary to press-fit the reinforcing member 1 into the fastened member 10, and the processing accuracy of the through holes 4 formed in the fastened member 10 and the press-fit accuracy of the reinforcing member 1 do not have to be increased.

（１１）被締結部材１０には成形時において、成形型の下型の凸部にあたる領域に締結用の貫通孔４が形成されている。そのため、成形後の被締結部材１０に締結用の貫通孔４を形成する必要がない。 (11) The fastening member 10 has a through hole 4 for fastening in a region corresponding to the convex portion of the lower mold of the molding die at the time of molding. Therefore, it is not necessary to form the through hole 4 for fastening in the fastened member 10 after molding.

（１２）炭素繊維である芯糸２及び組糸３は組紐状組織に形成されるため、補強部材１の円筒部５と第１フランジ部６及び第２フランジ部７とを連続して形成することができる。 (12) Since the core yarn 2 and the braid 3 which are carbon fibers are formed in a braided structure, the cylindrical portion 5 of the reinforcing member 1 and the first flange portion 6 and the second flange portion 7 are continuously formed. be able to.

（１３）補強部材１は第１フランジ部６及び第２フランジ部７を有するため、第１フランジ部６及び第２フランジ部７によりボルト８の応力を分散させることができ、貫通孔４の内部に配置された補強部材１と被締結部材１０の間に生じる割れや亀裂が防止される。 (13) Since the reinforcing member 1 has the first flange portion 6 and the second flange portion 7, the stress of the bolt 8 can be dispersed by the first flange portion 6 and the second flange portion 7. The crack and crack which arise between the reinforcing member 1 and the to-be-fastened member 10 which are arrange | positioned to are prevented.

（１４）被締結部材１０と補強部材１は一体に成形されるため、補強部材１を被締結部材１０の貫通孔４に嵌め込む必要がない。従って、補強部材１において第１フランジ部６及び第２フランジ部７が設けられた補強部材１を被締結部材１０の貫通孔４の内部に固定することができる。 (14) Since the fastened member 10 and the reinforcing member 1 are integrally formed, it is not necessary to fit the reinforcing member 1 into the through hole 4 of the fastened member 10. Therefore, the reinforcing member 1 provided with the first flange portion 6 and the second flange portion 7 in the reinforcing member 1 can be fixed inside the through hole 4 of the fastened member 10.

（第２の実施形態）
図４及び図５に示す第２の実施形態は、第１の実施形態における補強部材１の形状及び補強部材１における芯糸２の配向方向を変更したもので、第１の実施形態と同一の構成については同一の符号を付し、詳細な説明を省略する。 (Second Embodiment)
The second embodiment shown in FIGS. 4 and 5 is the same as the first embodiment except that the shape of the reinforcing member 1 in the first embodiment and the orientation direction of the core yarn 2 in the reinforcing member 1 are changed. The same reference numerals are given to the configurations, and detailed description is omitted.

図４に示すように、補強部材１５は円筒状に形成されている。円筒状の補強部材１５は第１の実施形態における補強部材１の円筒部５に対応する。組糸１７は芯糸１６と同じ太さであり、芯糸１６に対して交互にかつ斜めに交わされることにより組紐状組織に形成されている。芯糸１６は組糸１７と組み合された箇所において一部で図示しない屈曲を生じている。補強部材１５において、芯糸１６の長手方向が円筒の軸（後述する貫通孔２０の軸２０ａ）に対して５°傾いて配向されている。なお、芯糸１６の長手方向とは芯糸１６において屈曲した箇所を除き、芯糸１６が配向されている方向を指す。   As shown in FIG. 4, the reinforcing member 15 is formed in a cylindrical shape. The cylindrical reinforcing member 15 corresponds to the cylindrical portion 5 of the reinforcing member 1 in the first embodiment. The braid 17 has the same thickness as the core yarn 16, and is formed in a braided structure by crossing the core yarn 16 alternately and obliquely. The core yarn 16 is bent at a portion where it is combined with the braid 17 and is not shown. In the reinforcing member 15, the longitudinal direction of the core yarn 16 is oriented with an inclination of 5 ° with respect to a cylindrical axis (an axis 20 a of a through hole 20 described later). Note that the longitudinal direction of the core yarn 16 refers to the direction in which the core yarn 16 is oriented except for the bent portion of the core yarn 16.

被締結部材１８は熱硬化性樹脂をマトリックスとし束状の炭素繊維である炭素繊維束１９を含有する繊維強化複合材である。被締結部材１８は板状に形成されており、炭素繊維束１９は互いに直交するＸ，Ｙ，Ｚ軸方向に配向された三次元構造に形成されている。被締結部材１８には締結用の貫通孔２０が備えられている。補強部材１５の外周面は被締結部材１８の貫通孔２０の内周面と対応した形状に形成されている。   The fastened member 18 is a fiber-reinforced composite material containing a carbon fiber bundle 19 that is a bundle-like carbon fiber with a thermosetting resin as a matrix. The fastened member 18 is formed in a plate shape, and the carbon fiber bundle 19 is formed in a three-dimensional structure oriented in the X, Y, and Z axis directions orthogonal to each other. The fastened member 18 is provided with a through hole 20 for fastening. The outer peripheral surface of the reinforcing member 15 is formed in a shape corresponding to the inner peripheral surface of the through hole 20 of the fastened member 18.

図５に示すように、成形された補強部材１５は被締結部材１８における貫通孔２０の内周面に装着されている。補強部材１５の外周面は、貫通孔２０の内部において貫通孔２０の内周面との間に嵌め込みに要する図示しない隙間を介して配置されている。被締結部材１８の下面と金属材２１の上面とは重ね合わせて配置されており、被締結部材１８に形成された締結用の貫通孔２０の軸２０ａと金属材２１に形成された締結用の貫通孔２２の軸２２ａとが一致している。貫通孔２０及び貫通孔２２にはボルト２３が挿入されており、被締結部材１８と金属材２１はボルト２３及びナット２４により締結されている。   As shown in FIG. 5, the molded reinforcing member 15 is attached to the inner peripheral surface of the through hole 20 in the fastened member 18. The outer peripheral surface of the reinforcing member 15 is disposed inside the through hole 20 with a gap (not shown) required for fitting between the inner peripheral surface of the through hole 20. The lower surface of the member to be fastened 18 and the upper surface of the metal material 21 are arranged so as to overlap each other, and the shaft 20 a of the through hole 20 for fastening formed in the member to be fastened 18 and the fastening material formed in the metal material 21. The shaft 22a of the through hole 22 coincides. Bolts 23 are inserted into the through holes 20 and 22, and the fastened member 18 and the metal material 21 are fastened by bolts 23 and nuts 24.

従って、この実施形態によれば、第１の実施形態における（１）〜（８）と同様の効果の他に次の効果を得ることができる。   Therefore, according to this embodiment, the following effects can be obtained in addition to the same effects as (1) to (8) in the first embodiment.

（１５）補強部材１５には第１フランジ部６及び第２フランジ部７が形成されないため、第１フランジ部６及び第２フランジ部７を形成するのに必要な材料及び加工にかかるコストを削減することができる。 (15) Since the first flange portion 6 and the second flange portion 7 are not formed on the reinforcing member 15, the material and the processing cost required for forming the first flange portion 6 and the second flange portion 7 are reduced. can do.

（１６）補強部材１５には第１フランジ部６及び第２フランジ部７が形成されないため、成形後の補強部材１５を被締結部材１８の貫通孔２０に嵌め込むことができる。 (16) Since the first flange portion 6 and the second flange portion 7 are not formed on the reinforcing member 15, the molded reinforcing member 15 can be fitted into the through hole 20 of the fastened member 18.

本発明は、前記した各実施形態の構成に限定されるものではなく、本発明の趣旨の範囲内で種々の変更が可能であり、次のように実施することができる。   The present invention is not limited to the configuration of each of the embodiments described above, and various modifications are possible within the scope of the gist of the present invention, and can be implemented as follows.

○第１の実施形態及び第２の実施形態において、被締結部材１０，１８及び補強部材１，１５を構成する強化繊維は炭素繊維でなくてもよい。例えばガラス繊維であってもよい。被締結部材１０，１８及び補強部材１，１５に用いられる強化繊維の種類は１種類でなくてもよい。例えば補強部材１，１５において芯糸２，１６が炭素繊維であり、組糸３，１７がガラス繊維であるように複数の種類の強化繊維が用いられてもよい。また、例えば補強部材１，１５において組糸３，１７に芯糸２，１６よりも充分に細い糸を使用してもよい。その場合、組糸３，１７による芯糸２，１６の屈曲を少なくできる。   In the first embodiment and the second embodiment, the reinforcing fibers constituting the fastened members 10 and 18 and the reinforcing members 1 and 15 may not be carbon fibers. For example, glass fiber may be used. The type of reinforcing fiber used for the fastened members 10 and 18 and the reinforcing members 1 and 15 may not be one. For example, in the reinforcing members 1 and 15, a plurality of types of reinforcing fibers may be used such that the core yarns 2 and 16 are carbon fibers and the braided yarns 3 and 17 are glass fibers. For example, a thread sufficiently thinner than the core threads 2 and 16 may be used for the braiding threads 3 and 17 in the reinforcing members 1 and 15. In that case, the bending of the core yarns 2 and 16 by the braids 3 and 17 can be reduced.

○第１の実施形態において、ボルト８の頭部８ａにおける座面を第１フランジ部６からはみ出さずに配置できる形状であれば、円環状でなくてもよい。第１フランジ部６の径がボルト８の頭部８ａの径よりも小さい場合、ボルト８の頭部８ａと被締結部材１０が接触するために、被締結部材１０にクリープ変形が生じる。また、第１フランジ部６の径が大きすぎる場合、重量が増すという問題がある。このため、第１フランジ部６の径はボルト８の頭部８ａの径よりわずかに大きい程度であることが望ましい。好ましくは、第１フランジ部６の径は、（第１フランジ部６の径）＝（ボルト８の頭部８ａの径）＋（０．２×（被締結部材１０の板厚））であるのがよい。   In the first embodiment, the ring 8 may not have an annular shape as long as the seat surface of the head 8 a of the bolt 8 can be arranged without protruding from the first flange portion 6. When the diameter of the first flange portion 6 is smaller than the diameter of the head portion 8a of the bolt 8, the head portion 8a of the bolt 8 and the fastened member 10 come into contact with each other, so that creep deformation occurs in the fastened member 10. Moreover, when the diameter of the 1st flange part 6 is too large, there exists a problem that a weight increases. For this reason, it is desirable that the diameter of the first flange portion 6 is slightly larger than the diameter of the head 8 a of the bolt 8. Preferably, the diameter of the first flange portion 6 is (diameter of the first flange portion 6) = (diameter of the head portion 8a of the bolt 8) + (0.2 × (plate thickness of the fastened member 10)). It is good.

○第１の実施形態において、補強部材１の第１フランジ部６及び第２フランジ部７は芯糸２及び組糸３により組紐状組織に形成される際に、円筒部５と連続して形成されなくてもよい。例えば、束状の強化繊維により、円筒部５と第１フランジ部６あるいは第２フランジ部７とが別に形成された後に、樹脂により円筒部５と第１フランジ部６あるいは第２フランジ部７とが接合されてもよい。   In the first embodiment, the first flange portion 6 and the second flange portion 7 of the reinforcing member 1 are formed continuously with the cylindrical portion 5 when formed into a braided structure with the core yarn 2 and the braided yarn 3. It does not have to be done. For example, after the cylindrical portion 5 and the first flange portion 6 or the second flange portion 7 are separately formed by bundle-shaped reinforcing fibers, the cylindrical portion 5 and the first flange portion 6 or the second flange portion 7 are made of resin. May be joined.

○第１の実施形態において、補強部材１に必ずしも第１フランジ部６及び第２フランジ部７が設けられていなくても良い。第１フランジ部６及び第２フランジ部７のいずれか一方が設けられていてもよく、第１フランジ部６及び第２フランジ部７が設けられていなくてもよい。また、第２フランジ部７の形状は円環状でなくても良い。例えば、ボルト８の頭部８ａより径が小さくてもよい。   In the first embodiment, the reinforcing member 1 is not necessarily provided with the first flange portion 6 and the second flange portion 7. Either one of the first flange portion 6 and the second flange portion 7 may be provided, or the first flange portion 6 and the second flange portion 7 may not be provided. Further, the shape of the second flange portion 7 may not be an annular shape. For example, the diameter may be smaller than the head 8 a of the bolt 8.

○第１の実施形態において、第１フランジ部６及び第２フランジ部７が被締結部材１０の表面から突出して配置されなくてもよい。例えば、被締結部材１０において貫通孔４の周囲は第１フランジ部６及び第２フランジ部７の厚みの分だけ板厚が薄く成形されており、第１フランジ部６及び第２フランジ部７が貫通孔４の端部に配置されることで、被締結部材１０と第１フランジ部６及び第２フランジ部７の表面が平面をなしてもよい。この場合、被締結部材１０の貫通孔４の周囲においては、特開２００７−２６８９４１に開示されるように、繊維体積含有率（Ｖｆ）が高くなるため、クリープ抑制効果が高まる。   In the first embodiment, the first flange portion 6 and the second flange portion 7 may not be disposed so as to protrude from the surface of the fastened member 10. For example, in the fastened member 10, the thickness of the periphery of the through hole 4 is formed to be thin by the thickness of the first flange portion 6 and the second flange portion 7, and the first flange portion 6 and the second flange portion 7 are formed. By being arranged at the end of the through hole 4, the fastened member 10 and the surfaces of the first flange portion 6 and the second flange portion 7 may be flat. In this case, since the fiber volume content (Vf) is increased around the through hole 4 of the fastened member 10 as disclosed in JP-A-2007-268941, the creep suppressing effect is enhanced.

○第１の実施形態において、第１フランジ部６が当接される締結部材はボルト８でなくてもよい。例えば、ボルト８が金属材１２の貫通孔１３側から挿入されて、被締結部材１０の貫通孔４の上端から突出したボルト８の先端に対してナット１４が締結された場合に第１フランジ部６がナット１４と当接されてもよい。   In the first embodiment, the fastening member with which the first flange portion 6 abuts may not be the bolt 8. For example, when the bolt 8 is inserted from the through hole 13 side of the metal material 12 and the nut 14 is fastened to the tip of the bolt 8 protruding from the upper end of the through hole 4 of the member 10 to be fastened, the first flange portion 6 may abut against the nut 14.

○第１の実施形態において、補強部材１と被締結部材１０とは一体に成形されなくてもよい。補強部材１と被締結部材１０とがそれぞれ別に成形されて、成形後の被締結部材１０に形成された貫通孔４に補強部材１が嵌め込まれてもよい。   In the first embodiment, the reinforcing member 1 and the fastened member 10 do not have to be formed integrally. The reinforcing member 1 and the fastened member 10 may be formed separately, and the reinforcing member 1 may be fitted into the through hole 4 formed in the fastened member 10 after molding.

○第１の実施形態において、補強部材１及び被締結部材１０の製造方法は第１の実施形態に記載した方法に限らず、従来の繊維強化複合材の製造方法及び組紐状組織の製造方法並びに三次元織物の製造方法により製造されてもよい。   In the first embodiment, the manufacturing method of the reinforcing member 1 and the fastened member 10 is not limited to the method described in the first embodiment, and the conventional manufacturing method of the fiber-reinforced composite material, the manufacturing method of the braided structure, and You may manufacture by the manufacturing method of a three-dimensional fabric.

For example, a resin molded body may be used.

○第１の実施形態及び第２の実施形態において、少なくとも貫通孔４，２０の内部において炭素繊維が貫通孔４，２０の軸４ａ，２０ａ方向を向いて配向されていれば、炭素繊維が組紐状組織に形成されていなくてもよい。例えば、平織りあるいは袋織り状の織物により形成されていてもよい。また、例えば貫通孔に対応する形状の凸部を有する成形型を用いて補強部材を成形する場合に、凸部の外周面に炭素繊維が貫通孔の軸方向を向いて付着された状態で樹脂を注入して補強部材が成形されることで、貫通孔の内部に束状の炭素繊維が配置される場合であってもよい。   In the first embodiment and the second embodiment, if the carbon fibers are oriented at least in the through holes 4 and 20 in the direction of the axes 4a and 20a of the through holes 4 and 20, the carbon fibers are braided. It does not have to be formed in the texture. For example, it may be formed of a plain weave or bag-woven fabric. For example, when a reinforcing member is molded using a mold having a convex portion corresponding to the through hole, the resin is attached in a state where carbon fibers are attached to the outer peripheral surface of the convex portion in the axial direction of the through hole. When the reinforcing member is molded by injecting the carbon fiber, a bundle of carbon fibers may be disposed inside the through hole.

Good. It may be formed by drilling holes with a tool such as a drill in the fastened members 10 and 18 after molding. Further, after drilling, external processing such as deburring around the through hole 4 and cutting of unnecessary portions may be performed.

○第１の実施形態及び第２の実施形態において、被締結部材１０，１８の炭素繊維束１１，１９は三次元に配向していなくてもよい。例えば炭素繊維束１１，１９が二次元に配向されている場合であってもよいし、炭素繊維束１１，１９が一方向に配向されていてもよい。   In the first embodiment and the second embodiment, the carbon fiber bundles 11 and 19 of the fastened members 10 and 18 may not be oriented three-dimensionally. For example, the carbon fiber bundles 11 and 19 may be oriented two-dimensionally, or the carbon fiber bundles 11 and 19 may be oriented in one direction.

○第１の実施形態及び第２の実施形態において、被締結部材１０，１８と締結される他の部材は金属材１２，２０でなくてもよい。例えば、繊維強化複合材あるいは樹脂成形体であってもよく、壁、床や大地を構成する岩石等であってもよい。また、被締結部材１０，２０と締結される他の部材は板状である代わりに、棒状、柱状等別の形状であってもよい。   In the first and second embodiments, the other members that are fastened to the fastened members 10 and 18 may not be the metal materials 12 and 20. For example, it may be a fiber reinforced composite material or a resin molded body, or may be a rock that constitutes a wall, floor, or ground. Further, the other members to be fastened to the fastened members 10 and 20 may have other shapes such as a rod shape or a column shape instead of the plate shape.

○第１の実施形態及び第２の実施形態において、芯糸２，１６と組糸３，１７の径が異なってもよい。例えば、組紐３は芯糸２よりも十分細い糸であってもよい。その場合は、芯糸と組糸を組み合せることで組紐状に形成される際に、芯糸と組糸とが接触される箇所において芯糸に曲がる、折れる等の変形が生じる恐れがなく、芯糸を貫通孔の軸方向に真っ直ぐに配向することができる。   In the first embodiment and the second embodiment, the core yarns 2 and 16 and the braids 3 and 17 may have different diameters. For example, the braid 3 may be a thread sufficiently thinner than the core thread 2. In that case, when formed into a braid shape by combining the core yarn and the braided yarn, there is no risk of deformation such as bending or breaking in the core yarn at the location where the core yarn and the braided yarn are in contact with each other, The core yarn can be oriented straight in the axial direction of the through hole.
