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 rolls 10A, 10B and impregnating the reinforcing-fiber base material F with the thermoplastic resin P while rotating the pair of impregnating rolls 10A, 10B. The surface of each of the pair of impregnating rolls 10A, 10B has formed thereon a resin holding layer 12 that 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 layer 12 is elastically deformed.
A manufacturing method for a fiber-reinforced resin sheet, comprising:
A manufacturing device for a fiber-reinforced resin sheet, the device being configured to introduce a reinforcing-fiber base material in sheet form and a thermoplastic resin into a gap between a pair of impregnating rolls, and impregnating the reinforcing-fiber base material with the thermoplastic resin that is melted while rotating the pair of impregnating rolls, the device comprising:
