Abstract:
1. A thermoplastic pultrusion die system for pultruding a thermoplastic composite, comprising: a first pultrusion die member; a second pultrusion die member; a die cavity gap formed between the first pultrusion die member and the second pultrusion die member; a die cavity gap adjustment mechanism that imparts movement to at least one of the first pultrusion die member and the second pultrusion die member to vary the die cavity gap from closed to a specified location to open at a specified location; a pultrusion gripper mechanism having one or more grippers in series; a guidance and dispensing system including supports for rolls of material such that when the pultrusion gripper mechanism pulls a formed part through the first pultrusion die member and the second pultrusion die member, material including at least one of pre-preg thermoplastic material, high strength fiber thermoplastic material, fiber fabric thermoplastic material, and internal core material is pulled into the first pultrusion die member and the second pultrusion die member, and a computer numerical control (CNC) computer system controlling the die cavity gap adjustment mechanism and the pultrusion gripper mechanism, wherein the CNC computer system including
