In this paper, glass fiber fabric reinforced polyphenylene sulfide composites were prepared by hot pressing. The effects of glass fibre modification and hot pressing temperature on the properties of the composites were investigated using a scanning electron microscope, infrared spectrometer, universal testing machine, and DIGEYE digital imaging colour measurement system. The results show that after the treatment with a silane coupling agent, the silane coupling agent was more uniformly distributed on the surface of the glass fibres, and the bonding effect between the glass fibre fabric and polyphenylene sulphide was significantly improved. The strength of the composites increased and then decreased with the increase of hot pressing temperature, and the surface colour of the composites became darker and darker. When the hot-pressing temperature is 310 °C, the mechanical properties of glass fabric-reinforced polyphenylene sulfide composites are at their best, the tensile strength reaches 51.9 MPa, and the bending strength reaches 78 MPa.
本文采用热压法制备了玻璃纤维织物增强聚苯硫醚复合材料。利用扫描电子显微镜、红外光谱仪、万能试验机和DIGEYE数字成像颜色测量系统,研究了玻璃纤维改性和热压温度对复合材料性能的影响。结果表明,经硅烷偶联剂处理后,硅烷偶联剂在玻璃纤维表面分布更均匀,玻璃纤维织物与聚苯硫醚之间的粘结效果显著提高。复合材料的强度随热压温度的升高先增大后减小,且复合材料的表面颜色变得越来越深。当热压温度为310℃时,玻璃织物增强聚苯硫醚复合材料的力学性能最佳,拉伸强度达到51.9MPa,弯曲强度达到78MPa。
