Abstract
A method produces thermoplastic resin-impregnated sheet-shaped reinforcing fiber bundle obtained by impregnating reinforcing fibers made from continuous fibers with a thermoplastic resin, said method including: an application step in which a sheet-shaped reinforcing fiber bundle obtained by arranging reinforcing fibers made from continuous fibers in one direction is passed through an application section which retains thermoplastic resin, and the thermoplastic resin is applied to the sheet-shaped reinforcing fiber bundle to constitute a thermoplastic resin-impregnated sheet-shaped reinforcing fiber bundle; a further impregnation step in which the applied thermoplastic resin is further impregnated into the inside of the thermoplastic resin-impregnated sheet-shaped reinforcing fiber bundle; and a shaping step in which the thermoplastic resin-impregnated sheet-shaped reinforcing fiber bundle is shaped and solidified by cooling.
