In view of the research of carbon nanotubes (CNTs) reinforced aluminum matrix composites (AMCs), weak CNTs/Al interface bonding and adverse interface reaction are the key scientific problems which restrict the strengthening effect of CNTs in AMCs. This study proposed a new idea of introducing SiC transition layer between CNTs/Al interface based on the composite configuration and interface structure design of AMCs. The results showed that CNTs-SiC composite powders with controllable structure were successfully synthesized by carefully controlling the ratio between Si and CNTs. The adverse interface reaction was regulated and the interface coalescence between CNTs and Al matrix was enhanced effectively. It was also found that the thicker SiC layer consumed more energy in peeling and fracture during loading due to the carbide-linked inner walls provided stronger interlocked bonding, corresponding stronger ability to transfer the load from matrix to reinforcements and strengthen the load bearing capacity of CNTs in AMCs. Therefore, the mechanical performance of CNTs reinforced AMCs were significantly improved by further achieving the compounding effect of CNTs, which provide an effectual method and basis for the development and application of CNTs reinforced AMCs.

鉴于对碳纳米管（CNTs）增强铝基复合材料（AMCs）的研究，弱的CNTs / Al界面键合和不良的界面反应是限制CNTs在AMCs中增强作用的关键科学问题。本研究提出了一种基于AMC的复合结构和界面结构设计的在CNTs / Al界面之间引入SiC过渡层的新思路。结果表明，通过控制硅与碳纳米管的比例，可以成功合成结构可控的碳纳米管-碳化硅复合粉体。调节了不良的界面反应，有效增强了碳纳米管与铝基体之间的界面结合。还发现，较厚的SiC层在加载过程中在剥离和断裂过程中消耗了更多的能量，这是因为与碳化物相连的内壁提供了更强的互锁键合，相应的将载荷从基体转移到增强物的能力也更强，并增强了CNT的载荷能力。在AMC中。因此，通过进一步实现碳纳米管的复合作用，显着提高了碳纳米管增强AMC的力学性能，为碳纳米管增强AMC的开发和应用提供了有效的方法和依据。
