摘    要:以环氧树脂为基体、玄武岩短纤维为增强材料,制备了玄武岩短纤维/环氧树脂复合材料.研究了不同玄武岩短纤维含量对复合材料拉伸强度和耐磨性能的影响,采用扫描电子显微镜(SEM)观察了复合材料的断面形貌和磨损表面形貌,分析了磨损机制.结果表明,玄武岩短纤维/环氧树脂复合材料的抗拉强度和耐磨性能与纯环氧树脂相比均有不同程度的改善和提高,当玄武岩短纤维的含量为8%时,复合材料的拉伸强度最大;当玄武岩短纤维的含量为6%时,磨损率最低.随着玄武岩短纤维含量的增加,复合材料的磨损机制由黏着磨损向磨粒磨损转化.

关 键 词:环氧树脂  玄武岩短纤维  增强  复合材料  耐磨性

Abstract:Basalt chopped fiber/epoxy resin composite was synthesized from epoxy (matrix) and basalt chopped fiber (strengthe- ning agent). The effects of basalt chopped fiber content on the tensile strength and wear resistance were studied. The cross section sur- face and worn surface morphology of the composite was examined using Scanning Electron Microscope (SEM) and the wear mechanism was analyzed. The results show that the tensile strength and wear resistance of basalt chopped fiber/epoxy resin composite were im- proved compared with epoxy Matrix. Under the condition of 8% and 6% basalt chopped fiber, the basalt chopped fiber/epoxy resin composite exhibited the best tensile strength and wear resistance, respectively. With the increase of basalt chopped fiber content, the wear mechanism changed from adhesion wear gradually switched to abrasive wear.
Keywords:epoxy resin  basalt fiber  strengthen  composite  wear resistance
