摘　　要：采用熔体浸渍工艺制备了长玻纤(LGF)增强聚丙烯材料。研究了甲基丙烯酸缩水甘油酯接枝聚丙烯(PP-g-GMA)对长玻璃纤维增强聚丙烯(PP)复合材料力学性能的影响。结果表明:PP-g-GMA影响长玻璃纤维增强PP复合材料的力学性能;当PP-g-GMA质量分数为1%时,PP/LGF复合材料的力学性能最好,拉伸强度、弯曲强度和悬臂梁缺口冲击强度分别提高32.34%、27.38%和74.51%。Using the melt impregnation device, long glass fiber reinforced polypropylene were produced. Effect of PP-g-GMA on the mechanical properties of the long glass fiber reinforced composite was studied. The results showed that PP-g-GMA affected mechanical properties of long glass fiber reinforced PP composites; when the content of PP-g-GMA was 1%, PP/LGF composites obtained the best mechanical properties, tensile strength, flexural strength and Notched Izod impact strength increased respectively by 32.34%, 27.38% and 74.51%.
