摘要
研究了聚丙烯接枝马来酸酐(PP-g-MAH)用量、基体树脂流动性、玻纤形态和短玻纤的单丝直径对玻纤增强聚丙烯(PP)复合材料性能的影响。结果表明:随着PP-g-MAH用量的增加,复合材料的力学性能呈现先增加后减小的趋势,断面呈韧性断裂。基体树脂PP的熔体流动速率越大,复合材料的力学性能越好。短玻纤比长玻纤直接纱增强效果好,玻纤的单丝直径越细,复合材料的力学性能越好。当PP/PP-g-MAH/其他助剂质量比为67/2/1时,质量分数30%玻纤增强PP复合材料的性能较好。
The effect of the mechanical properties of glass fiber reinforced polypropylene composite was investigated with different contents of maleic anhydride grafted poly-propylene, different types of glass fibers and the diameter of single short glass fiber. The microstructure of GF/PP/PP-g-MAH composites was also investigated. The results showed that with the increase of the content of PP-g-MAH, the mechanical properties of glass fi- ber reinforced polypropylene composite had a great peak. The fracture of the composite was ductile fracture. With the increase of the melt flowing rate of the resin or the decrease of the diameter of single fiber, the mechanical properties of glass fiber reinforced polypropylene composite increased. The mechanical properties of short glass fiber rein-forced polypropylene composite were better than those of the others. When PP/PP-g-MAH/other reagents is 67/2/1 the mechanical properties of the polypropylene composite with 30% glass fiber were better.
