Abstract
A polyarylene sulfide resin composition contains 30% to 75% by weight of a polyarylene sulfide resin (A), 15% to 70% by weight of a fiber reinforcement (B) containing silic acid as a major component and having an average fiber diameter of 15 .mu.m or shorter and an average fiber length of 300 .mu.m or longer, and 1% to 25% by weight of a fiber reinforcement (C) containing Al.sub.2 O.sub.3 and SiO.sub.2 as major components in a ratio in weight of Al.sub.2 O.sub.3 to SiO.sub.2 ranging from 0.8 to 1 to 1.3 to 1 and having an average fiber diameter of 7 .mu.m or shorter and an average fiber length of 150 .mu.m or shorter. The composition is remarkable as molding material and a molded article resulting from the composition offers excellent mechanical strength and characteristics for metal plating. The metal-plated, molded article from the composition is particularly excellent in platability such as plate adhesion and plate gloss as well as short etching time.
