METHOD FOR MANUFACTURING LONG FIBER REINFORCED THERMOPLASTIC RESIN MOLDING MATERIAL

摘要

A method of making long fiber reinforced thermoplastic resin molding material is provided. The method includes the steps of filling a processing chamber (14) with molten thermoplastic resin, feeding at least one continuous fiber strand through that processing chamber, pultruding the continuous fiber strand (50) impregnated with the molten thermoplastic resin (56) and cutting at least one pultruded continuous fiber strand impregnated with the molten thermoplastic resin into pellets (60). The method also includes the processing of the pellets in accordance with a particular formula in order to ensure proper impregnation.
