摘　　要：研究了马来酸酐接枝聚丙烯(PP-g-MAH)和甲基丙烯酸缩水甘油酯接枝聚丙烯(PP-g-GMA)2种相容剂对碳纤维增强聚丙烯(CF/PP)复合材料性能的影响。结果表明:随着相容剂添加量的增加,CF/PP复合材料的拉伸强度、弯曲强度、缺口冲击强度增加,相容剂添加质量分数在6%时增加效果最为明显;2种相容剂对熔融温度及结晶度影响不大,但PP-g-MAH对CF/PP复合材料综合性能的提升优于PP-g-GMA。The effects of maleic anhydride grafted polypropylene(PP-g-MAH)and glycidyl methacrylate grafted polypropylene(PP-g-GMA)on the properties of carbon fiber reinforced polypropylene(CF/PP)composites were studied.The results show that the tensile strength,bending strength and notch impact strength of CF/PP composites increased with the increase of compatibilizer content,and the effect is most obvious when the mass fraction of compatibilizer is 6%.The two compatibilizers have little effect on the melting temperature and crystallinity,but PP-g-MAH has better effect on the comprehensive properties of CF/PP composites than PP-g-GMA.
