摘要: 在不同的工艺参数下对玻璃纤维/聚丙烯纤维(GF/PP)复合纤维织物使用模压成型方式制成层压板,通过正交试验方法,研究模压温度、模压压力、保压时间对复合纤维织物GF/PP复合材料力学性能的影响。采用拉伸强度、弯曲强度、冲击强度作为评价GF/PP复合材料层压板的力学性能指标。结果表明:采用先制成预浸料再模压成型的方式制作的层压板的综合力学性能要优于直接将GF/PP复合纤维织物叠放在模具里通过模压成型制成层压板的力学性能。模压温度为210 ℃,模压压力为10 MPa,保压时间为20 min是采用GF/PP复合纤维织物制作连续纤维增强聚丙烯层压板的最佳工艺参数。

Abstract: The glass fiber/polypropylene (GF/PP) commingled yarn was laminated by compression molding under various process parameters. The effects of molding temperature, molding pressure and dwell time on the mechanical properties of GF/PP composites were investigated by orthogonal test. Tensile strength, flexural strength and impact strength were used to evaluate the mechanical properties of GF/PP composite laminates. The results show that comprehensive mechanical properties could be improved by preloading before molding compared to the direct molding compression. The optimum process parameters of laminates made of GF/PP continuous composite fiber fabric was found, for which the molding temperature was 210 ℃, the pressure applied on the laminate was 10 MPa, and the holding time was set as 20 min.
