ABSTRACT:
An apparatus for and a method of manufacturing a fiber reinforced thermoplastic sheet-shaped molding including a pre-impregnating process and a final impregnating process. A sheet of thermoplastic resin and a web of reinforcement fibers are supplied through the pre-impregnating process during which the thermoplastic resin is sucked under the influence of a suction force so as to partially penetrate into interstices in the reinforcement fiber web while both are transported around and by a perforated rotary drum, thereby to form a first preformed sheet. The first preformed sheet is subsequently supplied to the final impregnating process during which an impregnating machine is employed. As the first preformed sheet is passed through the impregnating machine while compressed inwardly and heated, the thermoplastic resin is allowed to completely penetrate into the interstices in the reinforcement fiber web to complete the fiber reinforced thermoplastic sheet-shaped molding upon cooling thereof. The fiber reinforced thermoplastic sheet-shaped molding is made of thermoplastic resin impregnated with reinforcement fibers.
