Title:
FIBER-REINFORCED POLYARYLENE SULFIDE COPOLYMER COMPOSITE SUBSTRATE, METHOD FOR MANUFACTURING SAME, AND MOLDED ARTICLE INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2021/020334
Kind Code:
A1
Abstract:
A fiber-reinforced polyarylene sulfide copolymer complex substrate obtained by impregnating a continuous reinforcing fiber substrate, or a reinforcing fiber substrate in which discontinuous reinforcing fibers are dispersed, with a polyarylene sulfide copolymer, wherein the glass transition point of the polyarylene sulfide copolymer is 95°C to 190°C. Provided are a fiber-reinforced polyarylene sulfide copolymer composite substrate which has high workability during molding of a molded article from the composite substrate as well as increased rigidity at high temperature, while having the chemical resistance of polyarylene sulfide, and a molded article comprising the fiber-reinforced polyarylene sulfide copolymer composite substrate.
