Polypropylene/ whisker / talc composites were prepared by using whiskers and talc as the fillers, and then the mechanical properties were analyzed. The results show that when the mass ratio of talc/whisker is 12/8, the tensile yield strength, flexural strength, flexural modulus, impact strength and melt flow rate reach the optimal values.%以滑石粉和晶须为填料,制备了晶须和滑石粉共改性聚丙烯复合材料,并研究了该复合材料的力学性能.结果表明:当滑石粉与晶须质量百分比为12∶8时,复合材料的拉伸屈服强度、弯曲强度、弯曲模量、冲击强度和熔体流动速率等综合性能最佳.
