摘要

PROBLEM TO BE SOLVED: To provide a fiber-reinforced polypropylene-based resin composition for a compact with ribs, which has a good weld appearance and sunken rib appearance as well as high rigidity and impact strength; and a compact obtained by molding the same.;SOLUTION: Provided is a fiber-reinforced polypropylene-based resin composition for a compact with ribs, comprising 40 to 99 wt.% of a specific propylene-ethylene block copolymer (a) obtained by using a metallocene-based catalyst, and 1 to 60 wt.% of a specific fiber (b) (however, a total of (a) and (b) is 100 wt.%); and a compact with ribs obtained by molding the same.;COPYRIGHT: (C)2014,JPO&INPIT
