摘要
碳纳米管以其稳定的结构、优异的力学性能,成为复合材料的理想增强相。其增强效果受多方面因素影响,界面是决定其增强效果的关键因素之一,也是金属基复合材料的研究重点。简要介绍了碳纳米管增强铝基(CNTs/Al)复合材料的界面结合机制及界面对复合材料性能的影响,评述了热膨胀系数、制备方法、碳纳米管纯度等多种因素对CNTs/Al复合材料界面的影响,并提出了改善界面的方法。
With superior mechanical properties perfect reinforcement in composites. The enhancement and structural stability, carbon nanotubes （CNTs） become a effect of carbon nanotubes is decided by many factors, and interrace is one of the most important factors. Therefore, interface is an important research aspect of metal matrix composites. Interface binding mechanism of CNTs/Al composites and the influence of interface to the properties of com- posites are introduced. Factors including coefficient of thermal expansion, preparation method, purity of CNTs influencing the interface are discussed, and methods to improve the interfacial bonding are also put forward.
