Abstract
An extruder () and a method for producing high-fiber volume reinforced thermoplastic resin structures (), as well as a tape () having opposing resin rich portions () and a fiber rich portion () disposed therebetween and a method for impregnating at least one fiber roving () with a polymer resin to form a tape (The extruder () includes an impregnation die () having a channel () that applies pressurized molten thermoplastic resin to a plurality of rovings () drawn through the channel (), and a die () faceplate () facing the downstream side () of said die (). The faceplate () has a plurality of sizing holes () or a slot () arranged along a line that the resin-impregnated rovings () are simultaneously drawn through that remove excess resin and pultrude the resin-impregnated rovings () into rod-shaped or sheet-shaped structures. The faceplate () is spaced apart from the downstream side () of the die () to provide a gap () between the die () and a back side of the faceplate ().
