摘要： 向聚苯硫醚（PPS）和聚酰亚胺（PI）按90∶10比例(质量份比)混合物中，添加不同用量的氧化铝，利用平行双螺杆挤出机熔融共混制备了PPS/PI合金材料，考察了氧化铝用量对合金材料拉伸强度、弯曲强度、悬臂梁冲击强度、摩擦系数和磨损体积的影响。利用差热扫描量热仪（DSC）和热失重分析仪（TGA）研究了合金材料的结晶行为和热失重性能；同时在扫描电子显微镜（SEM）中观察了冲击断面形貌和摩擦面形貌。结果表明：氧化铝的加入对复合材料力学性能、耐摩擦性能和热性能有较大影响，并能够有效诱导PPS进行结晶。SEM观察发现，随氧化铝用量增加，摩擦面形貌表现为更加光滑，用量超过15质量份后，氧化铝分散效果变差。

Abstract: Polyphenylene sulfide（PPS）and Polyimide（PI） were mixed in a ratio of 90∶10.PPS/PI alloy were prepared by melt blending using parallel twin-screw extruder. The effects of alumina content on tensile strength, flexural strength, impact strength of cantilever beam, friction coefficient and wear volume of PPS/PI blends were investigated. The crystallization behavior and thermogravimetric properties of the blends were studied by differential scanning calorimeters (DSC) and thermogravimetric analysis (TGA).The impact section morphology and friction surface morphology were observed by scanning electron microscope (SEM).The results showed that the addition of alumina had great influence on mechanical properties, friction resistance and thermal properties of the composites, and PPS could be induced to crystallize effectively. SEM observation showed that the morphology of friction surface became smoother with the increase of the content of alumina, and the dispersion became worse when the content exceeded 15phr.
