Title:
炭素繊維強化複合材料の製造方法
Document Type and Number:
Japanese Patent JP5877431
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a fiber composite material which increases the elongation of a fabric sheet made of composite fiber thread in a molding process and improves its followability to a shape of any mold in the molding process and has high shaping property and enables the fiber reinforcement and to provide a molded product thereof.SOLUTION: A fiber reinforced composite material comprises a composite fiber yarn 1 with waviness which is formed by the rolled stitch of an engaging yarn 5 of a thermoplastic synthetic fiber yarn on a carbon fiber bundle 3 and/or a natural fiber yarn 4 with these yarns being subjected to varied tension. The composite fiber yarn 1 thus obtained is used as warp and/or weft to form a fabric sheet with a prescribed size. The fabric sheet thus obtained is heated to melt the synthetic fiber yarn therein so that the synthetic fiber yarn is integrally joined to the carbon fiber bundle and/or the natural fiber yarn, thereby forming the fiber reinforced composite material. A fiber reinforced composite mold is also obtained by molding the fiber reinforced composite material into a required curved surface shape.
