摘　　要：为改善玄武岩纤维织物复合材料中树脂基体与玄武岩纤维结合较差的状况,利用不同质量分数的硅烷偶联剂溶液对玄武岩纤维织物改性,再制备玄武岩纤维织物复合材料。通过扫描电镜观察不同质量分数硅烷偶联剂溶液改性前后玄武岩纤维的表面形态,利用红外光谱仪对比改性前后的玄武岩纤维中化学官能团的变化,借助织物万能强力仪研究改性前后玄武岩纤维织物复合材料的拉伸性能和弯曲性能。结果表明:硅烷偶联剂改性后,玄武岩纤维表面附着的颗粒物增加,纤维之间的抱合力增强,纤维中的官能团数量增多,纤维的表面化学活性增强,纤维和树脂的界面结合度提高。玄武岩纤维织物复合材料的拉伸性能和弯曲性能得到改善,并在硅烷偶联剂质量分数为8%时拉伸性能和弯曲性能达到最佳。In order to improve the poor bonding between resin matrix and basalt fibers in basalt fiber fabric composites,different mass fraction of silane coupling agent solution was used to modify basalt fiber fabrics,and then the basalt fiber fabric composites were prepared.The surface morphology of basalt fiber before and after modification with different mass fractions of silane coupling agent was observed by scanning electron microscope.The changes of chemical functional groups in basalt fiber before and after modification were compared by infrared spectrometer.The tensile and bending properties of basalt fiber fabric composites before and after modification were studied by fabric universal strength analyzer.The results showed that,after the modification of silane coupling agent,the particles attached to the surface of basalt fibers were increased,the binding force between fibers was enhanced,the number of functional groups in fibers was increased,the surface chemical activity of fibers was enhanced,the interface binding degree between fibers and resin was improved.The tensile and bending properties of basalt fiber fabric composites were improved,and the tensile and bending properties were both the best when the mass fraction of silane coupling agent was at 8%.
