摘　　要：采用玻璃纤维增强聚丙烯片材和流动模塑成型工艺试制汽车挡泥板。通过模具的合理设计,并设定了压力、温度、时间等成型工艺参数:模塑片材在220℃中预热10 min;成型压力15 MPa,保压1 min;模具工作温度120℃。压制出的产品具有良好的表面质量和优异的力学性能,制品合格率>95%,满足设计要求。Fender is manufactured using GMT by compression molding. Our research is to design the mould and optimize the molding parameters such as temperature, pressure, time, etc. When the processing conditions of the compression molding are given： the being blank preheated at 220℃ in 10 min, the molding pressure 15 MPa and the mold temperature 120℃, the products have good surface quality, dimension precision and excellent mechanical properties. The eligible ratio is more than 95 %, so the fenders meet the design requirements.
