摘　　要：研究了不同浓度盐酸刻蚀处理纤维表面后再进行硅烷KH550、铝锆偶联剂处理对玄武岩纤维增强酚醛树脂基复合材料力学性能的影响,并用扫描电子显微镜观察复合材料表面的胶合情况。结果表明:随着盐酸浓度的提高,玄武岩纤维增强酚醛树脂(BF-PF)复合材料拉伸性能先降低后升高,在12mol/L时达到最大值,弯曲性能和ILSS均降低,在6mol/L时为最大值。铝锆偶联剂处理的BF-PF复合材料的拉伸性能优于KH550处理的复合材料,但弯曲性能和ILSS低于KH550处理的复合材料。The mechanical properties of the basalt fiber reinforced products （BFRP） were studied with different concentrations of hydrochloric acid etching and different coupling agent treatment on basalt fiber. The SEM was used to study the glue of the BFRP interface. According to the results, along with hydrochloric acid concentration in- creased, the tensile properties of BF-PF first decreased then increased, and reached maximum at 12 tool/L, the flexu- ral properties and ILSS were in inverse proportion to reduce, and reached maximum at 6 mol/L. The tensile properties of the BF-PF composites treated by aluminium zirconium coupling agent is superior to KH550 processing, but its ben- ding performance and ILSS are inferior to KH550 processing.
