Abstract: A glass fiber reinforced polypropylene-polyamide resin composition which comprises:(a) a propylene-ethylene block copolymer of an ethylene content of 5-30 mole % and of a melt flow rate of not less than 1.5 g/10 minutes in amounts of 25-65% by weight; and(b) a polyamide in amounts of 75-35% by weight; the propylene-ethylene block copolymer and the polyamide amounting to 100% weight; and(c) glass fibers in amounts of 10-100 parts by weight in relation to 100 parts by weight of the total of the propylene-ethylene block copolymer and the polyamide;(d) a grafted polypropylene which has an unsaturated carboxylic acid or its derivatives grafted thereonto in amounts of 0.5-5 parts by weight in relation to 100 parts by weight of the total of the propylene-ethylene block copolymer and the polyamide; and(e) an organic peroxide in amounts of 0.02-0.5% by weight based on the propylene-ethylene block polymer.
