THERMOPLASTIC RESIN COMPOSITE MATERIAL, PRODUCTION THEREOF AND MOLDED ARTICLE OBTAINED THEREFROM

摘要

PURPOSE:To obtain a self-reinforcing type thermoplastic resin composite material excellent in handling properties and recovery reusability without employing an impregnation process being a subject of a fiber reinforced thermoplastic resin composite material. CONSTITUTION:In a thermoplastic resin composite material based on a fibril component composed of a crystalline thermoplastic resin (A) and a matrix component composed of a thermoplastic resin (B), a fibrile diameter is below 10mum and the aspect ratio of a fibril is 100 or more and fibrils are mutually arranged in an almost parallel state (a). The content of the crystalline thermoplastic resin (A) in the composite material is 10-80wt.% and the m.p. of (A) is higher than the m.p. or softening point of (B) by 10 deg.C or higher (b) and fibrils are uniformly dispersed in the cross section in the direction vertical to the orientation direction of the fibrils.
