摘要：为提高剑麻(SF)增强聚丙烯(PP)复合材料的韧性,分别采取乙烯-辛烯共聚物(POE)和马来酸酐接枝POE(POE-g-MAH)二种弹性体对其进行增韧改性;研究了弹性体和纤维用量的变化对SF/PP/弹性体三元复合体系力学性能的影响及其内在原因。结果表明:POE和POE-g-MAH对剑麻增强聚丙烯复合材料均有良好的增韧效果;仅从增韧效果而言,在弹性体用量较低阶段POE优于POE-g-MAH,但当弹性体增至30%以后,POE-g-MAH则好于POE;在拉伸强度、拉伸模量、弯曲强度及弯曲模量方面,POE-g-MAH均比POE效果更好。
To improve the toughness of polypropylene （PP）/sisal fibers （SF） composites through the addition of polyolefin elastomer （POE） and maleic anhydride grafted polyolefin elastomer （POE-g-MAH）, the effects of the elastomer and fiber content on the mechanical properties and the effecting reason of the SF/ PP/elastomer composites were investigated. The results showed that both POE and POE-g-MAH had good toughening effect on SF enhanced PP composites. On the toughening effect part, POE was better than POE-g- MAH; in the low content of elastomer process, however, when the content of the elastomer was more than 30%, POE-g-MAH was better than POE. At the aspects of tensile strength, tensile modulus, flexural strength and flexural modulus, POE-g-MAH was superior to POE.
