摘要：通过预混粉体浸渍工艺成型方法,制备了玻纤(GF)长度为6,12,24 mm的GF增强聚丙烯复合材料,研究了GF长度和含量对复合材料力学性能、热性能、结晶性能和动态力学性能等的影响,并利用扫描电子显微镜观察其冲击断面形态。结果表明,随着GF含量和长度的增加,复合材料的拉伸强度和冲击强度提高,在GF长度为6,12,24 mm时,复合材料的拉伸强度在GF质量分数为40%时比10%时分别提高160%,200%,200%;随着GF含量和长度的增加,复合材料的热变形温度和结晶性亦有明显的提高;冲击断面形态显示GF的加入起到阻碍裂纹扩展的作用。
The glass fiber（GF） reinforced polypropylene composites were prepared by powder pre-mixing impregnating process.The GF lengths were 6,12 and 24 mm.The mechanical properties, thermal properties, crystallize properties and dynamic mechanical properties of the composites were studied, and the impact fracture structure was investigated by scanning electron microscope.The results show that, with the increasing of GF content and length, the tensile strength and impact strength are improved ; as GF length is 6,12 and 24 mm, the tensile strength of composites is increased by 160%, 200% and 200% respectively when GF content increases from 10% to 40%, thermal distortion temperature and crystallization are also improved.The impact section of the composite shows that the addition of fiber plays the role of hindering crack propagation.
