本発明は、複合材同士を締結する複合材の締結装置、複合材の締結方法及び複合構造体に関するものである。   BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a fastening device for a composite material for fastening composite materials, a fastening method for the composite material, and a composite structure.

従来、複合材積層構造物の厚さ方向にピンを差し込んで層間性能を補強したり、複数の積層部材を連結したりする装置が知られている（例えば、特許文献１参照）。この装置で用いられるピンは、複合材積層構造物の厚さに合わせた長さとなっており、このピンの抜け落ちを防止するために、複合材積層構造物の下面にフィルムが付着されている。   DESCRIPTION OF RELATED ART Conventionally, the apparatus which inserts a pin in the thickness direction of a composite material laminated structure, reinforces interlayer performance, or connects a several laminated member is known (for example, refer patent document 1). The pins used in this device have a length matched to the thickness of the composite laminate structure, and a film is attached to the lower surface of the composite laminate structure to prevent the pins from falling off.

特表２０１０−５２２６５５号公報Japanese Patent Publication No. 2010-522655

特許文献１の装置では、ピンが複合材積層構造物の厚さに合わせた長さとなっていることから、ピンの抜け落ちを防止するためには、複合材積層構造物の下面にフィルムを付着する必要があり、作業が煩雑となってしまう。また、一般的に、ピンは、強化繊維に熱硬化性樹脂を含浸させて成形されたものであることから、ピンを折り曲げることができず、ピンに抜け止め部を形成することが困難であった。   In the device of Patent Document 1, since the pin has a length corresponding to the thickness of the composite laminate structure, a film is attached to the lower surface of the composite laminate structure to prevent the pin from falling off. It is necessary and the work becomes complicated. Also, in general, since the pin is formed by impregnating a reinforcing fiber with a thermosetting resin, the pin can not be bent and it is difficult to form a retaining portion on the pin The

そこで、本発明は、複合材同士の締結をより強固なものとすることができる複合材の締結装置、複合材の締結方法及び複合構造体を提供することを課題とする。   Then, this invention makes it a subject to provide the fastening device of the composite material which can make fastening of composite materials firmer, the fastening method of a composite material, and a composite structure.

本発明の複合材の締結装置は、厚さ方向に重ね合わされた複合材同士を締結する複合材の締結装置であって、強化繊維に樹脂を含浸させて成形されたピンが使用されており、前記複合材を挟んで、前記厚さ方向の両側に設けられる一対のヘッドと、一対の前記ヘッドにより挟まれた前記複合材を加熱して溶融させる加熱部と、一方の前記ヘッドに設けられ、前記加熱部により溶融した前記複合材の溶融部に対して、前記ピンを前記厚さ方向に打ち込むピン打ち部と、を備え、前記ピン打ち部は、一方の前記ヘッドから他方の前記ヘッドへ向けて前記ピンを打ち込むことで、前記ピンの他方側の端部を他方の前記ヘッドに当接させて変形させ、変形させた前記ピンの他方側の端部を、他方側抜け止め部として形成することを特徴とする。   The fastening device for a composite material according to the present invention is a fastening device for a composite material for fastening composite materials stacked in the thickness direction, and a pin formed by impregnating a reinforcing fiber with a resin is used. A pair of heads provided on both sides in the thickness direction, sandwiching the composite material, a heating unit for heating and melting the composite material sandwiched between the pair of heads, and one of the heads; And a pin-punched part for driving the pin in the thickness direction with respect to a melted part of the composite material melted by the heating part, the pin-punching part being directed from the one head to the other head The other end of the pin is made to abut against the other head to be deformed by driving the pin, and the other end of the deformed pin is formed as the other side retaining part It is characterized by

また、本発明の複合材の締結方法は、厚さ方向に重ね合わされた複合材同士を締結する複合材の締結方法であって、強化繊維に樹脂を含浸させて成形されたピンが使用されており、前記厚さ方向の両側から、一対のヘッドにより前記複合材を挟み込む挟持工程と、一対の前記ヘッドにより挟まれた前記複合材を加熱して溶融させる加熱工程と、前記加熱部により溶融した前記複合材の溶融部に対して、前記ピンを前記厚さ方向に打ち込むピン打ち工程と、を備え、前記ピン打ち工程では、一方の前記ヘッドから他方の前記ヘッドへ向けて前記ピンを打ち込むことで、前記ピンの他方側の端部を他方の前記ヘッドに当接させて変形させ、変形させた前記ピンの他方側の端部を、他方側抜け止め部として形成することを特徴とする。   Moreover, the fastening method of the composite material of the present invention is a fastening method of the composite material for fastening the composite materials overlapped in the thickness direction, and a pin formed by impregnating a reinforcing fiber with a resin is used. And the step of holding the composite material by a pair of heads from both sides in the thickness direction, the heating step of heating and melting the composite material held by a pair of heads, and melting by the heating unit And c. Driving the pin in the thickness direction with respect to a molten portion of the composite material, wherein the pin driving step is to drive the pin from the one head toward the other head. The other end of the pin is brought into contact with the other head for deformation, and the other end of the deformed pin is formed as the other side retaining part.

この構成によれば、加熱されることによって溶融した複合材の溶融部にピンを打ち込み、ピンの他方側の端部を他方側のヘッドに当接させて変形させることで、ピンに他方側抜け止め部を形成することができる。このため、他方側抜け止め部によりピンが複合材から抜けにくくなるため、ピンによる複合材同士の締結をより強固なものにすることができる。なお、他方側抜け止め部は、ピンの他方側の端部を一方向に折り曲げて変形させることで形成してもよいし、ピンの他方側の端部を放射方向に拡がるように変形させることで形成してもよい。   According to this configuration, the pin is driven into the melting portion of the composite material melted by heating, and the other end of the pin is abutted against the head on the other side to deform the other end of the pin. A stop can be formed. For this reason, since it becomes difficult to remove a pin from a composite material by the other side securing part, fastening of composite materials by a pin can be made stronger. The other side retaining portion may be formed by bending and deforming the other end of the pin in one direction, or deforming the other end of the pin so as to expand in the radial direction. It may be formed of

また、他方の前記ヘッドは、前記ピンが当接する当接面に形成され、前記ピンの他方側の端部を所定の方向に曲げる曲げガイドを有することが、好ましい。   Further, it is preferable that the other head has a bending guide which is formed on an abutting surface on which the pin abuts and which bends the other end of the pin in a predetermined direction.

この構成によれば、他方のヘッドの当接面にピンを当接させることで、曲げガイドに沿って打ち込まれるピンの他方側の端部を、好適に所定の方向に曲げることができる。   According to this configuration, by bringing the pin into contact with the contact surface of the other head, the other end of the pin driven along the bending guide can be suitably bent in a predetermined direction.

本発明の他の複合材の締結装置は、厚さ方向に重ね合わされた複合材同士を締結する複合材の締結装置であって、強化繊維に樹脂を含浸させて成形されたピンが使用されており、前記複合材を挟んで、前記厚さ方向の両側に設けられる一対のヘッドと、一対の前記ヘッドにより挟まれた前記複合材を加熱して溶融させる加熱部と、一方の前記ヘッドに設けられ、前記加熱部により溶融した前記複合材の溶融部に対して、前記ピンを前記厚さ方向に打ち込むピン打ち部と、を備え、前記ピン打ち部は、一方の前記ヘッドから他方の前記ヘッドへ向けて前記ピンを打ち込むことで、前記ピンの他方側の端部を前記複合材の内部で変形させ、変形させた前記ピンの他方側の端部を、他方側抜け止め部として形成することを特徴とする。   Another composite fastening device according to the present invention is a composite fastening device for fastening composites stacked in the thickness direction, and a pin formed by impregnating a reinforcing fiber with a resin is used. A pair of heads provided on both sides in the thickness direction, sandwiching the composite material, a heating unit for heating and melting the composite material sandwiched between the pair of heads, and one of the heads And a pin-punched part for driving the pin in the thickness direction with respect to the molten part of the composite material melted by the heating part, the pin-punching part moving from one head to the other head The other end of the pin is deformed in the inside of the composite by driving the pin toward the other, and the other end of the deformed pin is formed as the other side retaining part. It is characterized by

また、本発明の他の複合材の締結方法は、厚さ方向に重ね合わされた複合材同士を締結する複合材の締結方法であって、強化繊維に樹脂を含浸させて成形されたピンが使用されており、前記厚さ方向の両側から、一対のヘッドにより前記複合材を挟み込む挟持工程と、一対の前記ヘッドにより挟まれた前記複合材を加熱して溶融させる加熱工程と、前記加熱部により溶融した前記複合材の溶融部に対して、前記ピンを前記厚さ方向に打ち込むピン打ち工程と、を備え、前記ピン打ち工程では、一方の前記ヘッドから他方の前記ヘッドへ向けて前記ピンを打ち込むことで、前記ピンの他方側の端部を前記複合材の内部で変形させ、変形させた前記ピンの他方側の端部を、他方側抜け止め部として形成することを特徴とする。   Moreover, the fastening method of the other composite material of this invention is a fastening method of the composite material which fastens the composite materials piled together in the thickness direction, Comprising: The pin formed by impregnating resin with resin is used A sandwiching process of sandwiching the composite material by a pair of heads from both sides in the thickness direction, a heating process of heating and melting the composite material sandwiched by the pair of heads, and the heating unit And a pinning step of driving the pin in the thickness direction with respect to a melted portion of the molten composite material, and in the pinning step, the pin is moved from one head to the other head. The other end of the pin is deformed in the inside of the composite by driving, and the other end of the deformed pin is formed as the other side retaining part.

この構成によれば、加熱されることによって溶融した複合材の溶融部にピンを打ち込み、ピンの他方側の端部を複合材の内部において変形させることで、ピンに他方側抜け止め部を形成することができる。このため、他方側抜け止め部によりピンが複合材から抜けにくくなるため、ピンによる複合材同士の締結をより強固なものにすることができる。なお、他方側抜け止め部は、複合材の内部で折り曲がることによりアンカー効果を発揮可能な形状とすることがよい。   According to this configuration, the pin is driven into the molten part of the composite material melted by heating, and the other end of the pin is deformed in the composite material, thereby forming the other side retaining part on the pin can do. For this reason, since it becomes difficult to remove a pin from a composite material by the other side securing part, fastening of composite materials by a pin can be made stronger. In addition, it is good for the other side securing part to be made into the shape which can exhibit an anchor effect by bending inside a composite material.

また、前記ピン打ち部は、前記ピンの一方側の端部を前記複合材から露出させて打ち込み、一方の前記ヘッドは、前記複合材から露出する前記ピンの一方側の端部が変形するように移動し、変形させた前記ピンの一方側の端部を、一方側抜け止め部として形成することが、好ましい。   In addition, the pinning portion exposes and drives an end of one side of the pin from the composite material, and one of the heads has a shape such that an end of the one side of the pin exposed from the composite is deformed Preferably, one end of the pin moved and deformed is formed as a one-side retaining portion.

この構成によれば、一方のヘッドを移動させ、ピンの一方側の端部を変形させることで、ピンに一方側抜け止め部を形成することができる。このため、一方側抜け止め部によりピンが複合材から抜けにくくなるため、ピンによる複合材同士の締結をさらに強固なものにすることができる。   According to this configuration, it is possible to form the one-side retaining portion on the pin by moving one of the heads and deforming one end of the pin. For this reason, since it becomes difficult to remove a pin from a composite material by the one side securing part, fastening of the composite materials by a pin can be made still stronger.

また、前記ピンに含まれる前記樹脂及び前記複合材に含まれる樹脂は、熱可塑性樹脂及び熱硬化性樹脂の少なくとも一方を含むことが、好ましい。   Moreover, it is preferable that the resin contained in the pin and the resin contained in the composite material include at least one of a thermoplastic resin and a thermosetting resin.

この構成によれば、ピンの樹脂が熱可塑性樹脂で、複合材の樹脂が熱可塑性樹脂となるパターン、ピンの樹脂が熱可塑性樹脂で、複合材の樹脂が熱硬化性樹脂となるパターン、ピンの樹脂が熱硬化性樹脂で、複合材の樹脂が熱可塑性樹脂となるパターン、ピンの樹脂が熱硬化性樹脂で、複合材の樹脂が熱硬化性樹脂となるパターンの、４パターンがある。これらのパターンにおいて、加熱部によりピン及び複合材を適切に溶融させる加熱条件とすることで、複合材の溶融部におけるピンの打ち込みを好適に行うことができ、また、ピンの他方側抜け止め部の形成を好適に行うことができる。例えば、複合材の樹脂が熱硬化性樹脂である場合、所定の部位を熱硬化させる際にピンを打ち込むことで、熱硬化と同時に複合材の締結を行うことができる。   According to this configuration, a pattern in which the resin of the pin is a thermoplastic resin and the resin of the composite material is a thermoplastic resin, a pattern in which the resin of the pin is a thermoplastic resin and the resin of the composite is a thermosetting resin, the pin There are four patterns, a pattern in which the resin of the resin is a thermosetting resin and a resin of the composite material is a thermoplastic resin, and a pattern of the resin of the pins is a thermosetting resin and a resin of the composite material is a thermosetting resin. In these patterns, by setting the heating condition to appropriately melt the pin and the composite material by the heating portion, the pin can be suitably driven in the fusion portion of the composite material, and the other side retaining portion of the pin Can be suitably formed. For example, when the resin of the composite material is a thermosetting resin, fastening of the composite material can be performed simultaneously with the thermal curing by driving the pin when the predetermined portion is thermally cured.

また、前記ピンに含まれる前記樹脂と、前記複合材に含まれる樹脂とは、同じ樹脂であることが、好ましい。   Moreover, it is preferable that the said resin contained in the said pin and the resin contained in the said composite material are the same resin.

この構成によれば、複合材とピンとを好適に一体化させることができる。   According to this configuration, the composite material and the pin can be suitably integrated.

本発明の複合構造体は、厚さ方向に重ね合わされた複合材と、強化繊維に樹脂を含浸させて成形され、重ね合わされた前記複合材に打ち込まれることで、前記複合材同士を締結するピンと、を備え、前記ピンは、一方側の端部を変形させることで形成され、前記複合材からの前記ピンの抜け止めとなる一方側抜け止め部と、他方側の端部を変形させることで形成され、前記複合材からの前記ピンの抜け止めとなる他方側抜け止め部と、を有することを特徴とする。   The composite structure according to the present invention includes a composite material overlapped in the thickness direction, and a pin for fastening the composite materials by being driven into the composite material formed by impregnating a reinforcing fiber with a resin and being molded. , And the pin is formed by deforming one end portion, and is deformed by deforming the one end retaining portion that prevents the pin from coming off the composite material and the other end portion. And a second side retaining portion for retaining the pin from the composite material.

この構成によれば、ピンによる複合材同士の締結が強固となる複合構造体を提供することができる。なお、他方側抜け止め部は、複合材の外部に形成されてもよいし、複合材の内部に形成されてもよい。   According to this configuration, it is possible to provide a composite structure in which fastening of the composite materials by the pins is strong. In addition, the other side retaining part may be formed in the exterior of a composite material, and may be formed in the inside of a composite material.

複合構造体１０は、厚さ方向に重ね合わせた複数の複合材１１と、複数の複合材１１を締結するピン１２とを備えている。なお、実施形態１では、複数の複合材１１として、一対（２つ）の複合材１１を重ね合わせているが、３つ以上の複合材１１を重ね合わせてもよく、特に限定されない。   The composite structure 10 includes a plurality of composites 11 stacked in the thickness direction, and a pin 12 for fastening the plurality of composites 11. In the first embodiment, a pair of (two) composite materials 11 are stacked as the plurality of composite materials 11. However, three or more composite materials 11 may be stacked, and is not particularly limited.

複合材１１は、強化繊維に樹脂を含浸させたものであり、実施形態１では、板状に形成されている。強化繊維としては、例えば、炭素繊維が用いられるが、炭素繊維に限定されず、その他のプラスチック繊維、ガラス繊維、天然繊維又は金属繊維でもよい。また、樹脂としては、熱可塑性樹脂が用いられるが、加熱することにより溶融する樹脂であれば特に限定されず、熱硬化性樹脂を用いてもよい。熱可塑性樹脂としては、例えば、ポリエーテルエーテルケトン（ＰＥＥＫ）、ポリエーテルケトンケトン（ＰＥＫＫ）、及びポリフェニレンサルファイド（ＰＰＳ）等である。また、強化繊維基材に熱硬化性樹脂を含浸させた熱硬化プリプレグを用いてもよい。   The composite material 11 is obtained by impregnating a reinforcing fiber with a resin, and in the first embodiment, is formed in a plate shape. As the reinforcing fiber, for example, carbon fiber is used, but not limited to carbon fiber, other plastic fiber, glass fiber, natural fiber or metal fiber may be used. Although a thermoplastic resin is used as the resin, it is not particularly limited as long as it is a resin that melts by heating, and a thermosetting resin may be used. As a thermoplastic resin, it is polyetherether ketone (PEEK), polyether ketone ketone (PEKK), polyphenylene sulfide (PPS) etc., for example. Alternatively, a thermosetting prepreg may be used in which a reinforcing fiber substrate is impregnated with a thermosetting resin.

また、一対の複合材１１は、板面内において、厚さ方向に重複して設けられる。一対の複合材１１が重ね合わされる面同士、つまり、一対の複合材１１が厚さ方向において対向する面同士は、溶着されることで接合している。   Further, the pair of composite materials 11 are provided overlapping in the thickness direction in the plate surface. The surfaces on which the pair of composite materials 11 are superimposed, that is, the surfaces on which the pair of composite materials 11 face in the thickness direction are joined by welding.

ピン１２は、強化繊維に樹脂を含浸させたものであり、棒状に形成されている。ピン１２は、一対の複合材１１が重ね合わされる重複部位に打ち込まれている。ピン１２は、複合材１１と同様の強化繊維及び樹脂を用いてもよいし、締結に適した強化繊維及び樹脂を用いてもよく、特に限定されない。また、ピン１２に含まれる樹脂は、加熱することにより溶融する樹脂であればよい。このピン１２は、一対の複合材１１の重複部位に挿通される挿通部位１２ａと、他方側（図１の上側）の端部に形成される他方側抜け止め部１２ｂと、一方側（図１の下側）の端部に形成される一方側抜け止め部１２ｃとを有する。挿通部位１２ａは、複合材１１の厚さ方向に沿って設けられる。他方側抜け止め部１２ｂは、挿通部位１２ａに対して屈曲して設けられ、他方側の複合材１１ａの板面に沿って設けられる。一方側抜け止め部１２ｃは、挿通部位１２ａに対して屈曲して設けられ、一方側の複合材１１ｂの板面に沿って設けられる。また、他方側抜け止め部１２ｂと一方側抜け止め部１２ｃとが屈曲する方向は、挿通部位１２ａに対して相互に逆方向となっている。なお、実施形態１では、他方側抜け止め部１２ｂと一方側抜け止め部１２ｃとが屈曲する方向を逆方向としたが、屈曲する方向については特に限定されない。   The pin 12 is a reinforcing fiber impregnated with a resin, and is formed in a rod shape. The pin 12 is driven into an overlapping portion where the pair of composites 11 is overlapped. The pin 12 may use the same reinforcing fiber and resin as the composite material 11, or may use a reinforcing fiber and resin suitable for fastening, and is not particularly limited. Further, the resin contained in the pin 12 may be any resin that melts by heating. The pin 12 has an insertion portion 12a which is inserted into the overlapping portion of the pair of composite materials 11, and the other side retaining portion 12b formed at the end of the other side (the upper side in FIG. 1). And one side retaining part 12c formed at the end of the lower side). The insertion portion 12 a is provided along the thickness direction of the composite material 11. The other side retaining portion 12b is provided to bend with respect to the insertion portion 12a, and is provided along the plate surface of the composite material 11a on the other side. The one side retaining portion 12c is provided to be bent with respect to the insertion portion 12a, and is provided along the plate surface of the one side composite material 11b. Further, the bending directions of the other side retaining portion 12b and the one side retaining portion 12c are opposite to each other with respect to the insertion portion 12a. In the first embodiment, the direction in which the other-side slip prevention portion 12b and the one-side slip prevention portion 12c are bent is the reverse direction, but the direction of bending is not particularly limited.

上記の複合構造体１０は、ピン１２に他方側抜け止め部１２ｂ及び一方側抜け止め部１２ｃが設けられていることから、ピン１２が一対の複合材１１から抜け落ちることを抑制し、ピン１２による一対の複合材１１の連結を強固なものとしている。   Since the composite structure 10 described above is provided with the other side retaining portion 12 b and the one side retaining portion 12 c in the pin 12, the pin 12 is prevented from falling out of the pair of composite materials 11, and the pin 12 The connection of the pair of composite materials 11 is made strong.

次に、図２を参照して、実施形態１に係る締結装置２０について説明する。締結装置２０は、一対のヘッド２１と、加熱部２５と、ピン打ち部２８と、を備えている。   Next, the fastening device 20 according to the first embodiment will be described with reference to FIG. The fastening device 20 includes a pair of heads 21, a heating unit 25, and a pin driving unit 28.

一対のヘッド２１は、重ね合わされた一対の複合材１１の重複部位を、厚さ方向の両側から挟み込んで配置される。一対のヘッド２１は、例えば、鉛直方向の上側及び下側に設けられている。つまり、一対の複合材１１は、上側のヘッド２１ａと下側のヘッド２１ｂとの間に挟まれる。このため、一対の複合材１１は、その厚さ方向が鉛直方向となる。   The pair of heads 21 is disposed so as to sandwich the overlapping portion of the pair of composite materials 11 overlapped from each other in the thickness direction. The pair of heads 21 is provided, for example, on the upper side and the lower side in the vertical direction. That is, the pair of composite materials 11 is sandwiched between the upper head 21 a and the lower head 21 b. For this reason, the thickness direction of the pair of composite materials 11 is the vertical direction.

加熱部２５は、一対のヘッド２１により挟まれた一対の複合材１１の重複部位を加熱することで、重複部位における樹脂を溶融させている。加熱部２５は、一対のヘッド２１の内部にそれぞれ設けられるヒータ２５ａ，２５ｂを含む構成となっている。つまり、上側のヘッド２１ａの内部に、ヒータ２５ａが設けられ、下側のヘッド２１ｂの内部に、ヒータ２５ｂが設けられる。なお、加熱部２５は、一対の複合材１１の重複部位を加熱する構成であれば、いずれの構成であってもよく、例えば、磁場加熱等を適用してもよい。   The heating unit 25 melts the resin in the overlapping portion by heating the overlapping portion of the pair of composite materials 11 sandwiched by the pair of heads 21. The heating unit 25 is configured to include heaters 25 a and 25 b provided inside the pair of heads 21. That is, the heater 25a is provided inside the upper head 21a, and the heater 25b is provided inside the lower head 21b. In addition, as long as the heating part 25 is a structure which heats the duplication site | part of a pair of composite material 11, any structure may be sufficient, for example, magnetic field heating etc. may be applied.

ピン打ち部２８は、一対の複合材１１の重複部位に対して、下側のヘッド２１ｂから上側のヘッド２１ａへ向かって、ピン１２を打ち込むものである。ピン打ち部２８は、下側のヘッド２１ｂの内部に設けられている。ピン打ち部２８は、ピン１２を複合材１１へ向けて射出させるための複数の射出孔２３を含んで構成されている。複数の射出孔２３は、下側のヘッド２１ｂの複合材に当接する当接面から、複合材１１の厚さ方向を深さ方向として形成されている。そして、ピン打ち部２８は、図示しない押出手段によりピン１２を射出孔２３から押し出すことで、ピン１２を複合材１１へ向けて射出する。   The pinning portion 28 drives the pin 12 from the lower head 21 b toward the upper head 21 a with respect to the overlapping portion of the pair of composite materials 11. The pinning portion 28 is provided inside the lower head 21b. The pin portion 28 includes a plurality of injection holes 23 for injecting the pin 12 toward the composite material 11. The plurality of injection holes 23 are formed with the thickness direction of the composite material 11 as the depth direction from the contact surface in contact with the composite material of the lower head 21b. Then, the pinning unit 28 ejects the pin 12 toward the composite material 11 by pushing the pin 12 out of the injection hole 23 by an extrusion unit (not shown).

次に、図２から図４を参照して、締結装置２０を用いて、厚さ方向に重ね合わされた複合材同士を締結する複合材の締結方法について説明する。先ず、図２に示すように、締結装置２０は、一対のヘッド２１により、重ね合わされた一対の複合材１１の重複部位を、厚さ方向の両側から挟み込む（ステップＳ１１：挟持工程）。この後、締結装置２０は、加熱部２５により一対のヘッド２１を加熱することで、一対の複合材１１の重複部位を加熱して溶融させる（ステップＳ１２：加熱工程）。このため、一対の複合材１１の重複部位は、溶融部となる。   Next, with reference to FIGS. 2 to 4, a fastening method of a composite material will be described in which the composite materials stacked in the thickness direction are fastened using the fastening device 20. First, as shown in FIG. 2, the fastening device 20 sandwiches the overlapping portions of the pair of composite materials 11 overlapped by the pair of heads 21 from both sides in the thickness direction (step S11: pinching step). Thereafter, the fastening device 20 heats and melts the overlapping portion of the pair of composite materials 11 by heating the pair of heads 21 by the heating unit 25 (step S12: heating step). For this reason, the overlap part of a pair of composite materials 11 turns into a fusion part.

続いて、締結装置２０は、下側のヘッド２１ｂに設けられるピン打ち部２８により、複数の射出孔２３から複数のピン１２を射出する（ステップＳ１３：ピン打ち工程）。射出されたピン１２は、下側のヘッド２１ｂから上側のヘッド２１ａへ向かって、一対の複合材１１の重複部位に挿通される。重複部位を通過したピン１２は、図３に示すように、その他方側の端部が、上側ヘッド２１ａに突き当たることで屈曲し、上側のヘッド２１ａの複合材１１に当接する当接面に沿って変形する。そして、変形したピン１２の他方側の端部は、他方側抜け止め部１２ｂとして機能する。一方で、射出後のピン１２は、その一方側の端部が、複合材１１から露出し、射出孔２３に格納された状態となる。締結装置２０は、図４に示すように、下側のヘッド２１ｂを、複合材１１の板面に沿って、他方側抜け止め部１２ｂが延在する方向とは反対側の方向へ移動させる。そして、下側のヘッド２１ｂが移動することにより、ピン１２の一方側の端部は、複合材１１の板面に沿って屈曲し、一方側抜け止め部１２ｃとして機能する。   Subsequently, the fastening device 20 ejects the plurality of pins 12 from the plurality of ejection holes 23 by the pinning portion 28 provided in the lower head 21b (step S13: pinning step). The ejected pin 12 is inserted from the lower head 21 b toward the upper head 21 a into the overlapping portion of the pair of composite materials 11. As shown in FIG. 3, the other end of the pin 12 which has passed through the overlapping portion is bent as it abuts on the upper head 21a and is along the contact surface of the upper head 21a that abuts on the composite material 11 To transform. The other end of the deformed pin 12 functions as the other side retaining portion 12b. On the other hand, one end of the pin 12 after injection is exposed from the composite material 11 and stored in the injection hole 23. The fastening device 20 moves the lower head 21b along the plate surface of the composite material 11 in the direction opposite to the direction in which the other side retaining portion 12b extends, as shown in FIG. Then, when the lower head 21b moves, the end on one side of the pin 12 is bent along the plate surface of the composite material 11, and functions as the one side retaining portion 12c.

以上のように、実施形態１によれば、加熱されることによって溶融した複合材１１の重複部位にピン１２を打ち込み、ピン１２の他方側の端部を上側のヘッド２１ａに当接させて変形させることで、ピン１２に他方側抜け止め部１２ｂを形成することができる。このため、他方側抜け止め部１２ｂによりピン１２が複合材１１から抜けにくくなるため、ピン１２による複合材１１同士の締結をより強固なものにすることができる。   As described above, according to the first embodiment, the pin 12 is driven into the overlapping portion of the composite material 11 melted by heating, and the other end of the pin 12 is brought into contact with the upper head 21 a to deform By doing this, the other side retaining portion 12 b can be formed on the pin 12. For this reason, since it becomes difficult for the pin 12 to come off from the composite material 11 by the other side retaining part 12b, fastening of the composite material 11 with each other by the pin 12 can be made stronger.

また、実施形態１によれば、下側のヘッド２１ｂを移動させ、ピン１２の一方側の端部を変形させることで、ピン１２に一方側抜け止め部１２ｃを形成することができる。このため、一方側抜け止め部１２ｃによりピン１２が複合材１１から抜けにくくなるため、ピン１２による複合材１１同士の締結をさらに強固なものにすることができる。   Further, according to the first embodiment, by moving the lower head 21 b and deforming the end of one side of the pin 12, the one side retaining portion 12 c can be formed on the pin 12. For this reason, since it becomes difficult for the pin 12 to come off from the composite material 11 by the one side retaining part 12c, fastening of the composite material 11 with each other by the pin 12 can be further strengthened.

また、実施形態１によれば、ピン１２に含まれる樹脂及び複合材１１に含まれる樹脂を熱可塑性樹脂とすることで、加熱部２５によりピン１２及び複合材１１を適切に溶融させることができる。このため、複合材１１の重複部位（溶融部）におけるピン１２の打ち込みを好適に行うことができ、また、ピン１２の他方側抜け止め部１２ｂの形成を好適に行うことができる。   Further, according to the first embodiment, by using the resin contained in the pin 12 and the resin contained in the composite material 11 as the thermoplastic resin, the heating unit 25 can appropriately melt the pin 12 and the composite material 11. . Therefore, the pin 12 can be suitably driven in the overlapping portion (melted portion) of the composite material 11, and the other side retaining portion 12b of the pin 12 can be suitably formed.

また、実施形態１によれば、ピン１２に含まれる樹脂と、複合材１１に含まれる樹脂とを同じ樹脂とすることで、複合材１１とピン１２とを好適に一体化させることができる。   Further, according to the first embodiment, by making the resin contained in the pin 12 and the resin contained in the composite material 11 the same resin, the composite material 11 and the pin 12 can be suitably integrated.

また、実施形態１によれば、他方側抜け止め部１２ｂ及び一方側抜け止め部１２ｃが形成されたピン１２により、一対の複合材１１を強固に締結できるため、ピン１２による複合材１１同士の締結が強固となる複合構造体１０を提供することができる。   Further, according to the first embodiment, since the pair of composite materials 11 can be firmly fastened by the pins 12 on which the other-side slip prevention portion 12b and the one-side slip prevention portion 12c are formed, The composite structure 10 in which the fastening is strong can be provided.

なお、実施形態１では、ピン１２の他方側の端部を上側のヘッド２１ａに当接させて変形させることで、ピン１２に他方側抜け止め部１２ｂを形成したが、ピン１２の他方側の端部を上側のヘッド２１ａに当接させず、複合材１１中に留めてもよい。この場合においても、ピン１２による複合材１１同士の締結を行うことができる。   In the first embodiment, the other end of the pin 12 is brought into contact with the upper head 21 a and deformed to form the other side retaining portion 12 b in the pin 12. However, the other end of the pin 12 is formed. The end may not be in contact with the upper head 21 a, and may be held in the composite 11. Also in this case, fastening of the composite materials 11 by the pins 12 can be performed.

［実施形態２］
次に、図５を参照して、実施形態２に係る締結装置３０について説明する。なお、実施形態２では、重複した記載を避けるべく、実施形態１と異なる部分について説明し、実施形態１と同様の構成である部分については、同じ符号を付して説明する。図５は、実施形態２に係る締結装置のヘッドを示す模式図である。 Second Embodiment
Next, a fastening device 30 according to a second embodiment will be described with reference to FIG. In addition, in the second embodiment, in order to avoid redundant description, portions different from the first embodiment will be described, and portions having the same configuration as the first embodiment will be described with the same reference numerals. FIG. 5 is a schematic view showing a head of a fastening device according to a second embodiment.

実施形態２の締結装置３０は、実施形態１の締結装置２０の構成に加え、上側のヘッド２１ａの複合材１１が当接する当接面に、ピン１２を所定の方向に曲げる曲げガイド３１が形成されている。   In the fastening device 30 of the second embodiment, in addition to the configuration of the fastening device 20 of the first embodiment, a bending guide 31 which bends the pin 12 in a predetermined direction is formed on the contact surface of the upper head 21a on which the composite material 11 contacts. It is done.

曲げガイド３１は、上側のヘッド２１ａの当接面に対して窪んで形成される溝である。当接面の曲げガイド３１に突き当たるピン１２は、その他方側の端部が、所定の方向に屈曲する。   The bending guide 31 is a groove formed to be recessed with respect to the contact surface of the upper head 21a. The other end of the pin 12 which abuts against the bending guide 31 of the contact surface is bent in a predetermined direction.

以上のように、実施形態２によれば、上側のヘッド２１ａの当接面にピン１２を当接させることで、曲げガイド３１に沿って打ち込まれるピン１２の他方側の端部を、好適に所定の方向に曲げることができる。このため、ピン１２の形状をコントロールし易いものにすることができる。   As described above, according to the second embodiment, by bringing the pin 12 into contact with the contact surface of the upper head 21a, the other end of the pin 12 driven along the bending guide 31 is preferably provided. It can be bent in a predetermined direction. Therefore, the shape of the pin 12 can be easily controlled.

なお、実施形態２の曲げガイド３１は、ピン１２の他方側の端部を所定の方向に屈曲させる形状となっているが、この形状に特に限定されない。   In addition, although the bending guide 31 of Embodiment 2 has a shape in which the other end of the pin 12 is bent in a predetermined direction, the shape is not particularly limited to this shape.

［実施形態３］
次に、図６を参照して、実施形態３に係る複合構造体４０について説明する。なお、実施形態３では、重複した記載を避けるべく、実施形態１及び２と異なる部分について説明し、実施形態１及び２と同様の構成である部分については、同じ符号を付して説明する。図６は、実施形態３に係る複合構造体の模式図である。 Third Embodiment
Next, a composite structure 40 according to the third embodiment will be described with reference to FIG. In the third embodiment, parts different from the first and second embodiments will be described to avoid overlapping descriptions, and the same components as those in the first and second embodiments will be described with the same reference numerals. FIG. 6 is a schematic view of a composite structure according to a third embodiment.

実施形態３に係る複合構造体４０は、ピン４１の形状が、実施形態１のピン１２の形状と異なっている。具体的に、ピン４１は、一対の複合材１１の重複部位に挿通される挿通部位４１ａと、他方側（図６の上側）の端部に形成される他方側抜け止め部４１ｂと、一方側（図６の下側）の端部に形成される一方側抜け止め部４１ｃとを有する。挿通部位４１ａは、実施形態１と同様に、複合材１１の厚さ方向に沿って設けられる。他方側抜け止め部４１ｂは、挿通部位１２ａを中心に、他方側の複合材１１ａの板面に沿って放射状に広がって設けられる。一方側抜け止め部４１ｃは、他方側抜け止め部４１ｂと同様に、挿通部位１２ａを中心に、一方側の複合材１１ｂの板面に沿って放射状に広がって設けられる。   In the composite structure 40 according to the third embodiment, the shape of the pin 41 is different from the shape of the pin 12 of the first embodiment. Specifically, the pin 41 has an insertion portion 41a which is inserted into the overlapping portion of the pair of composite materials 11, and the other side retaining portion 41b formed at the end of the other side (the upper side in FIG. 6) It has the one side retaining part 41c formed in the end of (the lower side of FIG. 6). The insertion portion 41 a is provided along the thickness direction of the composite material 11 as in the first embodiment. The other side retaining portion 41b is provided so as to radially spread along the plate surface of the composite material 11a on the other side centering on the insertion portion 12a. The one-side retaining portion 41c is provided so as to radially spread along the plate surface of the one side composite material 11b around the insertion portion 12a, similarly to the other-side retaining portion 41b.

上記のような他方側抜け止め部４１ｂ及び一方側抜け止め部４１ｃを、実施形態１の締結装置２０を用いて形成する場合、締結装置２０は、例えば、各ヘッド２１ａ，２１ｂを、複合材１１の板面に対して叩くように動作させ、ピン４１の端部を潰すことで、ピン４１の端部を放射状に広がる形状とすることができる。また、上記のような他方側抜け止め部４１ｂ及び一方側抜け止め部４１ｃを、実施形態２の締結装置３０を用いて形成する場合、締結装置３０は、例えば、曲げガイド３１を、ピン４１の端部を放射状に広げることが可能な形状とする。   In the case where the other side retaining portion 41b and the one side retaining portion 41c as described above are formed using the fastening device 20 of the first embodiment, the fastening device 20 includes, for example, the respective heads 21a and 21b and the composite material 11 The end portion of the pin 41 can be shaped so as to expand radially by crushing the end portion of the pin 41 so that the end portion of the pin 41 is crushed. Further, in the case where the other side retaining portion 41 b and the one side retaining portion 41 c as described above are formed using the fastening device 30 of the second embodiment, the fastening device 30 may, for example, The end is shaped to be able to expand radially.

［実施形態４］
次に、図７を参照して、実施形態４に係る締結装置５０について説明する。なお、実施形態４でも、重複した記載を避けるべく、実施形態１から３と異なる部分について説明し、実施形態１から３と同様の構成である部分については、同じ符号を付して説明する。図７は、実施形態４に係る締結装置の動作を示す説明図である。 Fourth Embodiment
Next, a fastening device 50 according to a fourth embodiment will be described with reference to FIG. Also in the fourth embodiment, in order to avoid redundant description, parts different from the first to third embodiments will be described, and parts having the same configuration as the first to third embodiments will be described with the same reference numerals. FIG. 7 is an explanatory view showing the operation of the fastening device according to the fourth embodiment.

実施形態４の締結装置５０は、実施形態１のピン打ち工程Ｓ１３に代えて、他方側の複合材１１ａの内部で他方側抜け止め部１２ｂを形成するピン打ち工程Ｓ１３ａを行っている。なお、締結装置５０は、実施形態１の締結装置２０と同様の構成となっており、ピン１２の他方側の端部を他方側の複合材１１ａの内部で変形させるように、ピン打ち部２８からピン１２を射出する。   The fastening device 50 of the fourth embodiment performs the pinning step S13a for forming the other side retaining portion 12b inside the composite material 11a on the other side, instead of the pinning step S13 of the first embodiment. The fastening device 50 has the same configuration as the fastening device 20 of the first embodiment, and the pin driving portion 28 is configured to deform the other end of the pin 12 inside the composite 11a on the other side. Eject pin 12 from.

具体的に、ピン打ち工程Ｓ１３ａでは、締結装置５０のピン打ち部２８の複数の射出孔２３から複数のピン１２を射出する。射出されたピン１２は、下側のヘッド２１ｂから上側のヘッド２１ａへ向かい、その他方側の端部が、他方側の複合材１１ａの内部で変形する。変形したピン１２の他方側の端部は、他方側抜け止め部１２ｂとして機能する。なお、図７では、他方側抜け止め部１２ｂが一方向に屈曲する形状として図示しているが、この形状に特に限定されず、アンカー効果を発揮可能な形状であれば、いずれの形状であってもよい。ここで、ピン１２の他方側の端部を、他方側の複合材１１ａの内部で変形させる場合、ピン打ち工程Ｓ１３ａの前工程となる加熱工程Ｓ１２では、上側のヘッド２１ａにより他方側の複合材１１ａの表面を加熱せずに、下側のヘッド２１ｂにより一方側の複合材１１ｂを加熱することがよい。これにより、他方側の複合材１１ａの表面が軟化することがないことから、ピン１２が複合材１１の内部で変形し易いものにできる。   Specifically, in the pinning step S13a, the plurality of pins 12 are injected from the plurality of injection holes 23 of the pinning portion 28 of the fastening device 50. The ejected pin 12 goes from the lower head 21b to the upper head 21a, and the other end is deformed inside the composite 11a on the other side. The other end of the deformed pin 12 functions as the other side retaining portion 12b. In FIG. 7, the other side retaining portion 12 b is illustrated as a shape bent in one direction, but the shape is not particularly limited to this shape, and any shape may be used as long as it can exhibit an anchor effect. May be Here, when the end on the other side of the pin 12 is deformed inside the composite 11a on the other side, in the heating step S12, which is a step prior to the pinning step S13a, the composite on the other side by the upper head 21a. It is preferable to heat the composite material 11b on one side by the lower head 21b without heating the surface 11a. As a result, the surface of the other side composite material 11 a is not softened, so that the pin 12 can be easily deformed inside the composite material 11.

以上のように、実施形態４によれば、加熱されることによって溶融した複合材１１の重複部位にピン１２を打ち込み、ピン１２の他方側の端部を複合材１１の内部で変形させることで、ピン１２に他方側抜け止め部１２ｂを形成することができる。このため、他方側抜け止め部１２ｂによりピン１２が複合材１１から抜けにくくなるため、ピン１２による複合材１１同士の締結をより強固なものにすることができる。   As described above, according to the fourth embodiment, the pin 12 is driven into the overlapping portion of the composite material 11 melted by heating, and the other end of the pin 12 is deformed inside the composite material 11. The other side retaining portion 12 b can be formed on the pin 12. For this reason, since it becomes difficult for the pin 12 to come off from the composite material 11 by the other side retaining part 12b, fastening of the composite material 11 with each other by the pin 12 can be made stronger.
