Title:
REINFORCEMENT FIBER STRUCTURE AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2017/195710
Kind Code:
A1
Abstract:
[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.
