摘要
碳纤维增强铝基复合材料由于具有高的比强度、比模量、低热膨胀系数、良好的冲击韧度等优异性能而具有广阔的应用前景。针对铝熔体与碳纤维间润湿性较差的瓶颈问题,论述了碳纤维表面涂层工艺对其润湿性以及渗进行为的影响;总结了目前不同制备工艺的特点;分析了不同界面强化机制及其对复合材料界面失效行为及力学性能的影响。
Carbon fiber reinforced Al-matrix composites have great potential in a wide range of applications due to their high specific strength, specific modulus,low coefficient of thermal expansion and good impact toughness.In view of the bottleneck problem of poor wettability between molten Al and carbon fiber, the effects of surface coating technology of carbon fiber on the wettability and infiltration behavior were discussed. The characteristics of various fabrication processes was summarized. Different interfacial enhancement mechanisms and their effects on the interfacial failure behavior and mechanical properties of the composites were analyzed.
