Title (EN) REINFORCEMENT FIBER STRUCTURE AND METHOD FOR PRODUCING SAME
(FR) STRUCTURE DE FIBRES DE RENFORT ET PROCÉDÉ DE PRODUCTION ASSOCIÉ
(JA) 強化繊維構造物及びその製造方法
Abstract:
(EN) [Problem] To enable efficient production of a reinforcement fiber structure in which a core member and reinforcement fibers are integrally fused and shaped, and to provide a reinforcement fiber structure that exhibits a high bending strength when subjected to bending. [Solution] The present invention is provided with a bag-like portion by means of hollow weaving using reinforcement fibers 3 comprising reinforcement fiber (carbon fiber) filaments and a thermally fusible yarn 4, and is formed by covering a core member 2 with said bag-like portion by means of pressure bonding, welding, or firing. Since the bag-like portion 3a is formed by means of hollow weaving (or tubular knitting) using the reinforcement fiber 3, and since the core member 2 is covered by pressure-bonding, welding, or firing; a reinforcement fiber structure can be produced in which the thermally fusible yarn is melted by thermocompression bonding or the like so as to be fusion-bonded to the core member.
(FR) Le problème décrit par l'invention consiste à permettre une production efficace d'une structure de fibres de renfort, dans laquelle un élément central et des fibres de renfort sont fusionnés et formés d'un seul tenant et à fournir une structure de fibres de renfort qui présente une résistance élevée à flexion lorsqu'elle est soumise à une flexion. La solution selon la présente invention comprend une partie de type sac au moyen d'un tissage creux à l'aide de fibres de renfort (3) comprenant des filaments de fibres de renfort (fibre de carbone) et un fil thermofusible (4) et est formée par recouvrement d'un élément central (2) avec ladite partie de type sac au moyen de liaison par pression, soudure ou allumage. La partie de type sac (3a) étant formée au moyen d'un tissage creux (ou tricotage tubulaire) à l'aide de la fibre de renfort (3) et l'élément central (2) étant recouvert par liaison par pression, soudure ou allumage ; une structure de fibres de renfort peut être produite, dans laquelle le fil thermofusible est fondu par liaison par thermocompression ou analogue de manière à être lié par fusion à l'élément central.
(JA) 課題、芯部材と強化繊維が一体的に融合して所定にした強化繊維構造物が効率的に製造でき、曲げ加工すれば曲げ強度にも強い強化繊維構造物を提供する。 解決手段、 強化繊維(炭素繊維)の糸状と熱融着糸4からなる強化繊維3を用いて袋織りにより袋状部分が設けられ、芯部材2が圧着、溶着又は焼成により被覆されてなる。前記強化繊維3に袋織り(或いは袋編み)で形成された袋状部分3aが設けられ、芯部材2が入れられて圧着、溶着又は焼成により被覆されてなるので、熱圧着等により熱融着糸が溶融して芯部材に融合接着する強化繊維構造物が製造できる。
