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。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.
