MULTIAXIAL FABRIC, PREFORM MATERIAL AND FIBER-REINFORCED PLASTIC MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a multiaxial fabric capable of easily producing a preform material used for producing a fiber-reinforced plastic molded article, having a good compatibility with a resin, without reducing mechanical characteristics and capable of holding its shape along an objective molded material. SOLUTION: This multiaxial fabric consists of a laminated material 10 obtained by piling fiber-reinforcing sheets 10a-10f consisting of reinforcing fibrous material bundles 3 laid in parallel each other and resin impregnated reinforcing fibrous material bundles 5 by changing the fiber axis directions of the reinforcing fibrous materials each other and a stitch yarn 12 penetrating the laminated material in the thickness direction and reciprocating between the surface and reverse surface of the laminated material along the surface direction. The multiaxial fabric is useful for the production of the preform materials in a resin transfer-forming method and resin film infusion-forming method. COPYRIGHT: (C)2006,JPO&NCIPI
