摘　　要：研究了聚丙烯(PP)/三元乙丙橡胶(EPDM)复合材料的结构、制备条件对复合材料力学性能的影响。结果表明:该复合材料拉伸强度、弯曲强度和弯曲模量主要是由连续相PP决定;EPDM在PP中的分布和形态影响材料的冲击性能;随着EPDM含量的增加材料的冲击强度提高到46.9 kJ/m^2,断裂伸长率最大可达770%,但复合材料的流动性能略有下降。Morphology, mechanical properties and processing conditions of PP/EPDM composite materials were studied. The result shows that tensile strength, flexural strength and flexural modulus are mainly influenced by the PP continuous phase. The impact strength is influenced by distribution of dispersed particle and morphology. With increasing the mass fraction of EPDM,impact strength is also increased to 46.9 kJ/m^2 ,and maximum of elongation rate at break can be reached 770% but flow ability of the composite materials at high temperature is decreased in some sort.
