摘　　要：研究了玻璃微珠填充聚丙烯(PP)中玻璃微珠含量及粒径大小对复合材料力学性能和熔融、结晶行为的影响。结果表明:填充体系随着玻璃微珠含量增加,拉伸强度增加,冲击强度降低。在相同条件下,小粒径微珠填充体系拉伸强度和冲击强度均高于大粒径微珠填充体系。玻璃微珠在PP中具有成核作用,PP以异相成核方式结晶,提高了PP的结晶温度,结晶速率增大,流动性先增加后降低。The influencing effects of glass microballon content and particle size on the mechanical properties and behavior of melting and crystalline is studied. The results show that the tensile strength increases with increasing the content of the glass bead. At the same condition, the tensile and impact strength of bead filled system in smaller particle size are better than these of system in bigger one. Glass bead possesses nucleation, raising crystalline temperature and increasing crystallization rate. Flowability increases with increase the glass bead content, then it decreases.
