COMPOSITE YARN FABRIC AND METHOD FOR PRODUCING FIBER-REINFORCED RESIN MOLDED ARTICLE USING SAME

Document Type and Number:

WIPO Patent Application WO/2020/213416

Kind Code:

A1

Abstract:

Provided is a composite yarn fabric that can be used suitably as a material for a fiber-reinforced resin molded article. This composite yarn fabric is obtained by weaving in which composite yarn obtained by twisting together an inorganic multifilament yarn and a thermoplastic resin yarn is used in at least one of the warp and the weft. The inorganic multifilament yarn has a mass of 10-65 tex, and the monofilaments constituting the inorganic multifilament yarn have a fiber diameter of 6.6-9.5 μm. The melt flow rate of the thermoplastic resin constituting the thermoplastic resin yarn is 34-100 g/10 min. The ratio of the mass of the inorganic multifilament yarn to the total mass of the composite yarn is 40-90 mass%.
