Abstract

To provide a polyarylene sulfide (PAS) resin composition and a PAS resin molded article that are excellent in mechanical strengths such as impact resistance while maintaining excellent heat resistance of the PAS resin, and methods for producing the PAS resin composition and the PAS resin molded article. Specifically, provided are a method for producing a long fiber-reinforced PAS resin molded article, the method including obtaining a long fiber-reinforced PAS resin composition containing a PAS resin and a fiber reinforcing material having a fiber length of more than 5 mm, subsequently subjecting the resin composition and a PAS resin to dry blending, and subsequently subjecting the dry-blended substance to melting and subsequently to melt-molding; the long fiber-reinforced PAS resin composition; and a method for producing the long fiber-reinforced PAS resin composition.
