设计并制造了一台热塑性复合材料拉挤设备，部分用于验证理论过程模型，部分用于进行实验研究。所述的拉挤机包括筒子架、导向装置、红外预热器、加热和冷却模具以及拉动机构。实验工作描述了控制玻璃增强聚丙烯拉挤的工艺条件及其对最终性能的影响。所研究的工艺变量为预热温度、加热模具温度、冷却模具温度和拉伸速度，并根据三水平、18次田口方案进行变化。根据纤维在横截面上的分布、弯曲模数和强度、表面光洁度和拉力，通过对拉挤截面的表征来评估其效果。(C)1998年由爱思唯尔科学有限公司出版。
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.
