摘　　要：采用压力浸渗的方法成功制备了玄武岩纤维增强铝基复合材料;并根据热力学判据,分析了复合材料在Al-SiO2界面反应进行的详细过程及物质传输情况;在TEM和EDS结果的基础上讨论了界面反应层的结构;对制备的复合材料进行了力学性能试验。通过性能和断口分析认为,过强的界面结合强度是影响复合材料性能提高的关键因素。Basalt fiber reinforced aluminum matrix composites were successfully prepared with pressure infiltration process. The detailed process of mass transportation in the AI-SiO, interface reaction was discussed referring to the thermodynamic criterion. Based on the TEM and EDS characterizations, the structure of the interface reaction zone was proposed. Mechanical tests and fracture analysis indicate that the over-strong interracial bonding is the critical factor degrading material performance.
