Title:
SHEET FOR FIBER-REINFORCED RESIN AND FIBER-REINFORCED RESIN MOLDED ARTICLE USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/099611
Kind Code:
A1
Abstract:
Disclosed is a sheet for a fiber-reinforced resin formed of a composite fiber yarn which comprises a low-melting polymer component of a thermoplastic synthetic resin and a high-melting polymer component of a thermoplastic synthetic resin, wherein said low-melting polymer component and high-melting polymer component are polymers of the same kind; when molded into a fiber-reinforced resin article, said low-melting polymer component serves as a matrix resin while said high-melting polymer component serves as a reinforcing fiber; and said sheet is arranged as one or more layers at least in a single direction. Also disclosed is a fiber-reinforced resin molded article which is produced by heating the aforesaid sheet for a fiber-reinforced resin to a temperature being equal to or higher than the melting point of said low-melting polymer component but lower than the melting point of said high-melting polymer component, and compression-molding the same. Thus, a sheet for a fiber-reinforced resin, wherein the fiber-reinforced resin can be formed of thermoplastic synthetic resins, good adhesion can be achieved between a reinforcing fiber and a matrix resin and the ratio of the reinforcing fiber can be increased so as to achieve good physical characteristics such as strength, and a fiber-reinforced resin molded article using said sheet can be provided.
