Abstract
Provided is a manufacturing method for a fiber-reinforced resin sheet, the method being able to favorably impregnate a reinforcing-fiber base material with a thermoplastic resin. A fiber-reinforced resin sheet S is manufactured by introducing a reinforcing-fiber base material F in sheet form and a thermoplastic resin P into the gap between a pair of impregnating rollsA,B and impregnating the reinforcing-fiber base material F with the thermoplastic resin P while rotating the pair of impregnating rollsA,B. The surface of each of the pair of impregnating rollsA,B has formed thereon a resin holding layerthat elastically deforms along the thickness direction thereof when the impregnating rolls are pressed against each other and holds the molten thermoplastic resin P therein so as to be able to discharge the thermoplastic resin P upon pressing of the impregnating rolls against each other. Upon pressing of the impregnating rolls against each other, the reinforcing-fiber base material F is impregnated with the thermoplastic resin P while the resin holding layeris elastically deformed.
