Abstract
The present invention provides a method for manufacturing a fiber-reinforced resin substrate or a resin molded body, the method being capable of effectively performing impregnation of a reinforcing fiber material with a thermoplastic resin and having high productivity and economical efficiency, and an extruder for use in the manufacturing method. The manufacturing method of the invention is a method for manufacturing a fiber-reinforced resin substrate or resin molded body obtained by impregnating a reinforcing fiber material with a thermoplastic resin, including placing the reinforcing fiber material on a molten resin of the thermoplastic resin and pressurizing the same to impregnate the reinforcing fiber material with the molten thermoplastic resin, and subsequently, cooling and solidifying the reinforcing fiber material impregnated with the molten thermoplastic resin.
