采用差示扫描量热仪研究玄武岩纤维和硅烷偶联剂KH-550对聚丙烯（ PP）结晶性能的影响规律，并研究改性处理及纤维含量对复合材料力学性能的影响。结果表明：在玄武岩/PP复合体系中，玄武岩纤维的加入充当了PP结晶时成核剂的作用，有利于PP在纤维表面处异相成核，使复合体系的结晶度增大；KH-550改善了纤维与基体树脂的界面相容性，加速了PP在复合材料界面处异相成核，使其结晶度增加；纤维含量及KH-550质量分数对复合材料力学性能的影响与其对结晶度的影响相一致，且当纤维质量分数为40％、KH-550质量分数为0．75％时，复合材料的力学性能最佳。

DSC was used to investigate the effect of basalt fiber and silane coupling agent KH-550 on the crystallization of polypropylene ( PP) , and also studied the effect of modification and fiber content on the mechanical properties of the composites .The results show that in basalt/PP composite system , basalt fiber pro-motes the heterogeneous nucleation on the surface of the fiber and the crystallinity of PP .The addition of KH-550 improves the interface compatibility of the fiber and matrix , makes the heterogeneous nucle-ation at the interface of the composite faster and increase the crystallizaty degree of basalt /PP.The effect of fiber content and concentration of KH-550 on the mechanical properties of the composites are the same as their effects on the crystallinity .When the fiber content is 40%, and the concentration of KH-550 is 0 .75%, the mechanical properties of the composite reach the best .
