Description
本発明は、熱可塑性樹脂を含む材料からなり、締結部品により他の部材と機械接合される被固定部材の損傷部の補修方法に関する。 The present invention relates to a repair method for a damaged portion of a fixed member that is made of a material containing a thermoplastic resin and is mechanically joined to another member by a fastening component.
一般的に、熱可塑性樹脂材料、熱可塑性樹脂複合材料等の熱可塑性樹脂を含む材料からなる被固定部材を、締結部品により他の部材と機械接合する場合、締結部品による被固定部材の機械接合部近傍（例えば締結孔近傍）に応力が集中し、他の部分と比較して機械接合部近傍に損傷が発生しやすい。
この機械接合部近傍では、安定破壊モードである面圧破壊(締結部品が母材に食い込む形態で破壊する)が起こるように設計されているため、長期使用において損傷が徐々に発生し、接合強度を低下させる。
さらに、多数の損傷が発生して機械接合部近傍で繋がることで、損傷サイズが大きくなり、致命的な破壊に至る可能性もあり、機械接合部の信頼性を確保し使用期間を延ばすためには、損傷を修理することが必要である。
Generally, when a fixed member made of a material containing a thermoplastic resin such as a thermoplastic resin material or a thermoplastic resin composite material is mechanically bonded to another member by a fastening component, the mechanical bonding of the fixed member by the fastening component is performed. Stress concentrates in the vicinity of the part (for example, in the vicinity of the fastening hole), and damage is likely to occur in the vicinity of the mechanical joint as compared with other parts.
In the vicinity of this mechanical joint, it is designed so that the surface pressure fracture that is a stable fracture mode (destructed in a form in which the fastening part bites into the base metal) occurs, so that damage occurs gradually in long-term use, and the joint strength Reduce.
Furthermore, since many damages are generated and connected in the vicinity of the mechanical joint, the damage size increases, which may lead to fatal destruction. To ensure the reliability of the mechanical joint and extend the service life It is necessary to repair the damage.
熱可塑性樹脂は加熱により軟化するため、この時に加圧して溶着することで、充分な接合強度が得られる。
したがって、機械接合部近傍の損傷発生領域を加熱、加圧により溶着接合し、損傷が修理できると考えられる。
例えば、加熱したこてを用いて圧力を与え、熱可塑性樹脂で発生した損傷を修理する手法（特許文献１等参照）、電熱線を用いて熱可塑性樹脂を加熱して修理する方法（特許文献２等参照）、金属を高周波誘電加熱によって加熱して修理する方法（特許文献３等参照）、熱可塑性樹脂を加熱し圧力を与えることで修理する方法（特許文献４等参照）等が公知である。
Since the thermoplastic resin is softened by heating, sufficient bonding strength can be obtained by pressurizing and welding at this time.
Therefore, it is considered that the damage occurrence region near the mechanical joint can be welded and joined by heating and pressurizing to repair the damage.
For example, a method of repairing damage generated in a thermoplastic resin by applying pressure using a heated iron (see Patent Document 1, etc.), a method of heating and repairing a thermoplastic resin using a heating wire (Patent Document) 2), a method of repairing a metal by heating by high frequency dielectric heating (see Patent Document 3), a method of repairing a thermoplastic resin by heating and applying pressure (see Patent Document 4, etc.), etc. is there.
しかしながら、これらの公知の方法は、損傷部を直接外部から加熱、加圧するものであり、締結部品により機械接合がなされ、締結部品による被固定部材の機械接合部近傍で発生した損傷に適用した場合、損傷部である締結部品の直下及び近傍のみ加熱、加圧することが困難であるという問題点がある。
したがって、損傷部を加熱、加圧するためには、締結部品を取りはずすことが避けられない。
However, these known methods are those in which the damaged part is directly heated and pressurized from the outside, and is mechanically joined by the fastening part, and is applied to damage that occurs near the mechanical joint of the fixed member by the fastening part. There is a problem that it is difficult to heat and press only under and near the fastening part which is a damaged part.
Therefore, in order to heat and pressurize the damaged part, it is inevitable to remove the fastening part.
そこで、本発明は前述した課題を解決するものであり、締結部品を取りはずすことなく熱可塑性樹脂を含む材料からなる被固定部材の機械接合部の修理を可能とし、被固定部材の損傷部の効率的な補修方法を提供することを目的とする。 Accordingly, the present invention solves the above-described problems, and enables the repair of the mechanical joint portion of the fixed member made of a material containing a thermoplastic resin without removing the fastening parts, and the efficiency of the damaged portion of the fixed member.

また、締結力を受ける限られた領域のみを加熱することで、与える熱量を調整して損傷部のみを効率的に加熱することが可能となるとともに、損傷部以外への熱の影響を抑制し、効率的に、かつ、確実に強度を保って補修することが可能となる。
さらに、締結部品の締結力が加圧力として作用しているため、加熱と同時に加圧することが可能となり、損傷部が確実に熱溶着されて、熱可塑性樹脂を含む材料からなる被固定部材を効率的に、確実に補修することが可能となる。
According to the repair method according to claim 1, a part or all of the region that receives pressure by the fastening component near the mechanical joint portion of the fixed member is heated to a temperature equal to or higher than the softening point of the thermoplastic resin. By softening the thermoplastic resin near the mechanical joint of the member to be fixed, the damaged part is thermally welded, and it becomes possible to repair the damage of the member to be fixed containing the thermoplastic resin without removing the fastening parts. .
In addition, by heating only a limited area that receives the fastening force, it is possible to efficiently heat only the damaged part by adjusting the amount of heat applied, and to suppress the influence of heat to other than the damaged part. This makes it possible to repair efficiently and reliably while maintaining the strength.
Further, since the fastening force of the fastening parts acts as a pressing force, it is possible to pressurize simultaneously with heating, the damaged part is reliably thermally welded, and the fixed member made of a material containing a thermoplastic resin is efficiently used. Thus, it is possible to reliably repair.

本請求項４に記載の構成によれば、締結部品を増し締めすることにより、補修時に締結部品の締結力が低下するのを補うとともに、損傷部にさらに加圧力を与えることができ、より確実に損傷部が熱溶着されて、熱可塑性樹脂を含む材料からなる被固定部材を確実に補修することが可能となる。
本請求項５に記載の構成によれば、締結部品が発熱体であり、通電されることにより発熱し加熱されることにより、さらに容易に加熱することができ熱可塑性樹脂を含む材料からなる被固定部材を容易に補修することが可能となる。

また、熱可塑性樹脂からなる充填材がクッション材としても作用するため、損傷そのものを抑制することが可能となる。
According to the configuration of the second aspect of the present invention, the damaged part is heated by the heat transfer from the fastening part, so that the damaged part can be easily heated.
According to the configuration of the third aspect of the present invention, since the fastening part is formed in a shaft shape that is fixed through the fastening hole, it is easier to heat the fastening part, and heat is transferred to the damaged part. Therefore, it is possible to efficiently and surely repair the fixed member made of the material containing the thermoplastic resin by more efficiently and reliably heat-damaging the damaged portion.
According to the configuration described in claim 4, by tightening the fastening part, it is possible to compensate for a decrease in the fastening force of the fastening part at the time of repair, and to apply additional pressure to the damaged part, and more reliably. The damaged portion is thermally welded to the fixed member, so that the fixed member made of a material containing the thermoplastic resin can be reliably repaired.

図１に示すように、熱可塑性樹脂を含む材料からなる被固定部材１１０の締結孔１１１にボルト１２１とナット１２２からなる締結部品１２０を挿通して他の部材との間で締め付けて固定された状態で、締結部品１２０と直交する方向（図示の左右方向）に力Ｆが加わった場合、締結部品１２０に撓みが生じ、被固定部材１１０の締結孔１１１の縁部に大きな力が加わる。
この力によって、締結部品１２０との接触部である締結孔１１１の近傍に様々な損傷が発生する。
例として、図２に、炭素繊維強化樹脂複合材の締結孔（機械接合部）における典型的な破壊形態の断面写真を示す。
この例では、締結孔の近傍に、繊維破断、欠け、層間剥離等の損傷が発生している。
また、図２では明瞭には現れていないが、樹脂割れが発生することもある。
熱可塑性樹脂は加熱・加圧することで融着接合できることが知られており、被固定部材１１０に熱可塑性樹脂が含まれていた場合、図３に示すように、締結部品１２０の近傍を加熱、加圧することにより、損傷を修理することが可能である。
As shown in FIG. 1, a fastening part 120 made of a bolt 121 and a nut 122 is inserted into a fastening hole 111 of a fixed member 110 made of a material containing a thermoplastic resin, and is fastened and fixed between other members. In the state, when a force F is applied in a direction orthogonal to the fastening component 120 (the left-right direction in the drawing), the fastening component 120 is bent, and a large force is applied to the edge of the fastening hole 111 of the fixed member 110.
Due to this force, various damages occur in the vicinity of the fastening hole 111 that is a contact portion with the fastening component 120.
As an example, FIG. 2 shows a cross-sectional photograph of a typical fracture mode in a fastening hole (mechanical joint) of a carbon fiber reinforced resin composite material.
In this example, damage such as fiber breakage, chipping, and delamination occurs in the vicinity of the fastening hole.
Moreover, although it does not appear clearly in FIG. 2, a resin crack may occur.
It is known that the thermoplastic resin can be fusion bonded by heating and pressurizing. When the thermoplastic resin is contained in the fixed member 110, the vicinity of the fastening part 120 is heated as shown in FIG. Damage can be repaired by applying pressure.
本発明の第１実施形態に係る補修方法は、図４に示すように、締結部品１２０の両端に電極１２３を接触させて通電し、締結部品１２０自身を発熱させるように構成される。
締結部品１２０からの伝熱で、被固定部材１１０の機械接合部の近傍の熱可塑性樹脂が軟化し、また、締結部品１２０は、被固定部材１１０に対して所定の力で締め付けられているため、その締め付け圧が加圧力として働き、機械接合部の近傍の熱可塑性樹脂が熱溶着され、損傷が補修される。
なお、締結部品１２０は、直接電極１２３を接触させず、電磁誘導で締結部品１２０の内部に渦電流を発生させて発熱させてもよい。
As shown in FIG. 4, the repair method according to the first embodiment of the present invention is configured such that the electrodes 123 are brought into contact with both ends of the fastening part 120 to be energized and the fastening part 120 itself generates heat.
The heat transfer from the fastening part 120 softens the thermoplastic resin in the vicinity of the mechanical joint portion of the fixed member 110, and the fastening part 120 is fastened to the fixed member 110 with a predetermined force. The tightening pressure acts as an applied pressure, and the thermoplastic resin in the vicinity of the mechanical joint is thermally welded to repair the damage.
The fastening component 120 may generate heat by generating an eddy current in the fastening component 120 by electromagnetic induction without directly contacting the electrode 123.
また、図５に示すように、締結部品１２０の中心部に、あらかじめマイクロヒータ等の発熱体１３０を埋め込んでおき、発熱体１３０に通電することで発熱させ、締結部品１２０の表面に伝熱して被固定部材１１０の機械接合部の近傍の熱可塑性樹脂を加熱してもよい。
さらに、図６に示すように、締結部品１２０の露出部にマイクロヒータ等の発熱体１３０を接触させ、発熱体１３０に通電することで発熱させ、締結部品１２０を通じて伝熱して被固定部材１１０の機械接合部の近傍の熱可塑性樹脂を加熱してもよい。
Further, as shown in FIG. 5, a heating element 130 such as a micro heater is embedded in the center of the fastening part 120 in advance, and the heating element 130 is energized to generate heat and transfer heat to the surface of the fastening part 120. The thermoplastic resin in the vicinity of the mechanical joint of the fixed member 110 may be heated.
Further, as shown in FIG. 6, a heating element 130 such as a micro heater is brought into contact with the exposed portion of the fastening component 120, and heat is generated by energizing the heating element 130, and the heat is transferred through the fastening component 120. The thermoplastic resin in the vicinity of the mechanical joint may be heated.
本発明の第２実施形態に係る補修方法は、図７に示すように、締結部品１２０を加熱するとともに、締結部品１２０を増し締めするように構成される。
締結部品１２０からの伝熱で、被固定部材１１０の機械接合部の近傍の熱可塑性樹脂が軟化し、また、締結部品１２０を増し締めすることで加圧を加えて、機械接合部の近傍の熱可塑性樹脂が熱溶着され、損傷が補修される。
被固定部材１１０の機械接合部の近傍の損傷によって、あるいは、補修時の熱可塑性樹脂の軟化によって当初の締結部品１２０による締め付け圧が充分に得られない場合や、締結部品１２０に緩みが生じている場合でも、締結部品１２０を増し締めすることで、確実に加圧して熱可塑性樹脂を熱溶着し、損傷を確実に補修することができる。
As shown in FIG. 7, the repair method according to the second embodiment of the present invention is configured to heat the fastening part 120 and retighten the fastening part 120.
The heat transfer from the fastening part 120 softens the thermoplastic resin in the vicinity of the mechanical joint of the member 110 to be fixed, and pressurizes the fastening part 120 by further tightening, thereby increasing the pressure near the mechanical joint. The thermoplastic resin is thermally welded to repair the damage.
Due to damage near the mechanical joint of the fixed member 110 or due to softening of the thermoplastic resin at the time of repair, sufficient fastening pressure by the initial fastening part 120 cannot be obtained, or the fastening part 120 is loosened. Even when the fastening part 120 is tightened, it is possible to surely pressurize and heat-seal the thermoplastic resin to reliably repair the damage.
本発明の第３実施形態に係る補修方法は、図８に示すように、被固定部材１１０の機械接合部の近傍の表面に発熱体１３０を接触させ、直接、被固定部材１１０を加熱して締結部品１２０により締結力を受ける領域を加熱するものである。
この加熱で、被固定部材１１０の機械接合部の近傍の熱可塑性樹脂が軟化し、また、締結部品１２０は、被固定部材１１０に対して所定の力で締め付けられているため、その締め付け圧が加圧力として働き、機械接合部の近傍の熱可塑性樹脂が熱溶着され、損傷が補修される。
なお、図９に示すように、例えば、電磁波により加熱する加熱手段１３１を、被固定部材１１０の機械接合部の近傍の表面から離れた位置に配置してもよい。
また、前述の第２実施形態と同様に、加熱とともに締結部品１２０を増し締めしてもよい。
In the repair method according to the third embodiment of the present invention, as shown in FIG. 8, the heating member 130 is brought into contact with the surface in the vicinity of the mechanical joint of the fixed member 110 and the fixed member 110 is directly heated. The region receiving the fastening force by the fastening component 120 is heated.
This heating softens the thermoplastic resin in the vicinity of the mechanical joint portion of the member to be fixed 110, and the fastening component 120 is fastened to the member to be fixed 110 with a predetermined force. It acts as a pressing force, and the thermoplastic resin in the vicinity of the mechanical joint is thermally welded to repair the damage.
As shown in FIG. 9, for example, the heating means 131 that heats by electromagnetic waves may be arranged at a position away from the surface in the vicinity of the mechanical joint portion of the fixed member 110.
Further, similarly to the above-described second embodiment, the fastening component 120 may be tightened together with heating.
本発明の第４実施形態に係る補修方法は、図１０に示すように、被固定部材１１０の機械接合部と締結部品１２０とが接触する部分に、熱可塑性樹脂材料１４０を設けたものである。
補修時、前述の第１実施形態乃至第４実施形態と同様に加熱することで、被固定部材１１０に欠損等があった場合でも、熱可塑性樹脂材料１４０も軟化して破損部分に進入して補填しつつ、被固定部材１１０の熱可塑性樹脂を熱溶着して確実に補修することが可能となる。
また、熱可塑性樹脂材料１４０がクッション材としても作用するため、損傷そのものを抑制することが可能となる。
熱可塑性樹脂材料１４０は、被固定部材１１０に含まれる熱可塑性樹脂と異なる材質であってもよく、同じ材質であるのが望ましい。
なお、図１１に示すように、熱可塑性樹脂材料１４０を、被固定部材１１０の両表面側まで満たす構成としてもよい。
また、前述の第２実施形態と同様に、加熱とともに締結部品１２０を増し締めしてもよい。

While making up, the thermoplastic resin of the fixed member 110 can be heat-welded and reliably repaired.
Further, since the thermoplastic resin material 140 also acts as a cushioning material, damage itself can be suppressed.
The thermoplastic resin material 140 may be a different material from the thermoplastic resin contained in the fixed member 110, and is preferably the same material.
In addition, as shown in FIG. 11, it is good also as a structure filled with the thermoplastic resin material 140 to the both surface side of the to-be-fixed member 110. FIG.
