Title
(EN) SHEET-SHAPED REINFORCED-FIBER BASE MATERIAL AND MANUFACTURING METHOD THEREFOR
(FR) MATÉRIAU DE BASE EN FIBRES RENFORCÉES EN FORME DE FEUILLE ET SON PROCÉDÉ DE FABRICATION
(JA) シート状強化繊維基材およびその製造方法
Abstract
(EN)
The present invention addresses the problem of providing: a sheet-shaped reinforced-fiber base material (pseudo textile) that can follow a three-dimensional shape with shearing deformability, and that can significantly improve the yield of reinforced fibers and reduce a manufacturing cost by suppressing the occurrence of an end material; and a manufacturing method therefor. Disclosed is the sheet-shaped reinforced-fiber base material that is obtained with the provision of a plurality of reinforced-fiber bundles having any length and has N layers (N is an integer of three or more) of a laminated structure, the sheet-shaped reinforced-fiber base material satisfying respective conditions (1) to (5).
(FR)
La présente invention aborde le problème de la fourniture : d'un matériau de base en fibres renforcées en forme de feuille (pseudo textile) qui peut suivre une forme tridimensionnelle ayant une déformabilité de cisaillement, et qui peut améliorer de manière significative le rendement de fibres renforcées et réduire un coût de fabrication par suppression de l'apparition d'un matériau d'extrémité ; et de son procédé de fabrication. La présente invention porte sur le matériau de base en fibres renforcées en forme de feuille qui est obtenu avec la fourniture d'une pluralité de faisceaux de fibres renforcées ayant une longueur quelconque et qui comporte N couches (N étant un nombre entier égal ou supérieur à trois) d'une structure stratifiée, le matériau de base en fibres renforcées en forme de feuille remplissant les conditions respectives (1) à (5).
(JA)
せん断変形性を有し、三次元形状に追従することができ、かつ、端材の発生の抑制により強化繊維の歩留まりを大幅に改善し、製造コストが低減できるシート状強化繊維基材(擬似織物)、ならびに、その製造方法を提供することを課題とする。 任意の長さの強化繊維束を複数配設して得られる、N層(Nは3以上の整数)の積層構造を有する、シート状強化繊維基材であって、(1)~(5)の各条件を満たすシート状強化繊維基材が開示される。
