中文摘要：

采用示差扫描量热仪（DSC）研究了不同含量PET（聚对苯二甲酸乙二醇酯）纤维的PET／IPP（全同立构聚丙烯）复合材料的非等温结晶特性，考察了降温速率及PET纤维含量对PET／iPP复合材料非等温结晶性能的影响。结果表明，PET纤维可提高iPP的结晶温度，减少结晶时间，增大结晶速率。

英文摘要：

Non-isothermal crystallization kinetics of PET/iPP composites were studied by DSC at various content of PET fiber. The effects of cooling rate and PET fiber content on the non-isothermal crystallization behavior of PET/iPP were investigated. The results show that the addition of PET fiber can increase the crystallization temperature of PP, lead to a decrease in time of crystallization, and increase the rate of crystallization.
