POLYAMIDE RESIN COMPOSITION AND MOLDING FORMED OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polyamide resin composition and a molding excellent in shock resistance as well as in rigidity and dimensional stability when absorbing water, and excellent in molding property. SOLUTION: The polyamide resin composition contains: (A) a copolyamide resin comprising 70 to 85 mass% of a hexamethylene adipamide unit (N66) obtained from hexamethylene diamine and adipic acid and 15 to 30 mass% of a hexamethylene isophthalamide unit (N6I) obtained from hexamethylene diamine and isophthalic acid; (B) an aliphatic polyamide resin obtained from aminocarboxylic acid and/or a combination of diamine and dicarboxylic acid, in which a ratio (C/N) of the number of carbon atoms to nitrogen atoms included in the resin ranges from 7 to 12; and (C) a glass fiber. The mass ratio (A/B) of the component (A) to the component (B) ranges from 40/60 to 60/40; and the component (C) is included by 20 to 250 parts by mass with respect to total 100 parts by mass of the component (A) and component (B).
