摘要：

A machine for pultrusion of thermoplastic composites was designed and built, partly to verify theoretical process models and partly to conduct experimental studies. The pultrusion machine described includes creel, guidance device, infrared preheater, heated and cooled dies, and a pulling mechanism. The experimental work describes the process conditions which govern the pultrusion of glass reinforced polypropylene and their behaviour on the final properties. The process variables investigated were preheating temperature, heated die temperature, cooled die temperature and pulling speed and they were varied according to a three-level, 18-run Taguchi scheme. Their effect was assessed by the characterization of pultruded sections based upon fibre distribution over a cross-section, flexural modulus and strength, surface finish, and pulling force.
