FIBER-POLYPROPYLENE RESIN COMPOSITE AND ITS PELLET, AND FIBER-REINFORCED RESIN ARTICLES MADE THEREFROM AND SUPERIOR IN CREEP CHARACTERISTIC

摘要

PURPOSE: Provided are fiber-reinforced resin articles superior in creep characteristic, and fiber-polypropylene resin composites and pellets thereof which are superior in creep characteristic and suitable as the raw material of the fiber-reinforced resin articles. CONSTITUTION: The fiber-polypropylene resin composite comprises 20-95% by weight of component (A) defined below and 5-80% by weight of component (B) which is fiber having a weight average length of 2-100 mm, provided that the contents of components (A) and (B) are based on the combined weight of components (A) and (B): component (A): a propylene-based resin that comprises component (A-1) which is a propylene-based random copolymer obtained by polymerization of propylene and at least one kind of monomer selected from the group consisting of ethylene and -olefin, the propylene-based resin having a content of the polymerized monomer units derived from the monomers belonging to the group consisting of ethylene and -olefin of 0.1-3% by weight; or a modified propylene-based resin obtained by modification of the propylene-based resin with an unsaturated carboxylic acid or its derivative, provided that the content of the polymerized monomer units is based on the weight of the whole polymerized monomer units contained in the propylene-based resin.
