摘　　要：研究了长玻璃纤维/PP复合材料的力学性能和纤维在基体中的分布状况。结果表明：长玻纤在基体中呈现三维空间交叉分布,这种结构大幅度提高了复合材料的拉伸强度、冲击强度、硬度及软化点温度；玻纤的长度和用量对三维交叉结构的形成有很大影响；偶联剂KH-550处理玻纤表面后,材料的力学性能提高不大。The mechanical properties and the distribution of the long glass fibre in long glass fibre/PP composite were studied. The results showed the fibre distributed in the matrix in the way of 3D cross structure, which improved the tensile strength, impact strength, hardness and yield point of the composite greatly. The length and content of the fibre had great effect on the formation of the 3D cross structure; the effect of the treatment of the fiber by coupling agent KH-550 on the mechanical properties of the composite was little.
