PROBLEM TO BE SOLVED: To provide a glass fiber-reinforced polyolefinic resin composition having excellent injection moldability, high mechanical strength and high impact strength (impact strength at a low temperature face) together. SOLUTION: This glass fiber-reinforced polyolefinic resin composition is composed of following components A to C. (A) A propylene.ethylene block copolymer having >=0.906 g/cm<3> density, <=140,000 average molecular weight of a propylene homopolymer part and >=450,000 average molecular weight of an ethylene.propylene copolymer part and containing <=12 wt.% content of the copolymer part in the block copolymer in an amount of 89.9-57 wt.%, (B) an unsaturated carboxylic acid-modified polypropylenic resin in an amount of 0.1-3 wt.% and (C) glass fibers in an amount of 10-40 wt.%. |
