基于PIF制备一种高性能聚苯硫醚复合材料

摘要

采用压力诱导流动成型(PIF)方法来调控聚苯硫醚(PPS)/玻璃纤维(GF)/碳纤维(CF)三元复合材料的本体结构.并对三元复合材料进行了傅立叶红外光谱分析(FT-IR)、形貌观察(SEM)、力学性能测试、动态力学测试(DMA)和DSC测试,考察了PIF成型的效果.结果表明,在该三元体系中,当CF的质量分数为0.5％时,PIF成型后的复合材料性能最佳,拉伸强度达到362.33 MPa,弯曲强度达到408.11MPa,冲击强度达到14.35 kJ/m2.%Pressure-induced flow-forming (PIF) was used to control the bulk structure of PPS/GF/CF composites.The ternary composites were characterized by Fourier transform infrared spectroscopy (FT-IR),morphology observation (SEM),mechanical property test,dynamic mechanical test (DMA) and DSC respectively.The results show that when the mass fraction of CF is 0.5 ％,the properties of PIF composites are the best,and the tensile strength is 362.33 MPa,and the flexural strength is 408.11 MPa and the impact strength is 14.35 kJ/m2.
