Title: Method for opening and resin-impregnation to produce continuous fiber-reinforced thermoplastic resin composite material

Abstract: An opening and resin-impregnation apparatus is used for impregnating a reinforcing fiber bundle (2) with a molten resin. The fiber bundle (2) is subjected to opening by bringing it into contact with opening pins (4). An auxiliary pin (5) is positioned within a specific region relative to the opening pin. The apparatus and a method which makes use of the apparatus permit the production of a continuous fiber-reinforced thermoplastic resin composite material having excellent impregnation characteristics and flexural strength while maintaining high stable productivity.
