Abstract

Single-walled carbon nanotube (SWCNT)-aluminum (Al) composites with three distinct microstructural architectures (nanolaminated structure with relatively weak interfacial bonding, partial laminated structure with strong interfacial bonding, and disordered microstructure) were fabricated. Tensile test revealed that partial laminated composite possessed the highest yield and tensile strengths with an almost identical uniform elongation among the three composites, which were rationalized by grain refinement of Al matrix, effective load-sharing of SWCNTs, and enhanced interface-dislocation interactions in partial laminated composite.

单壁碳纳米管-铝复合材料的微观结构与力学行为的相关性

摘要

制备了具有三种不同的微结构结构（具有相对较弱的界面键合的纳米结构，具有较强的界面键合的局部层压结构和无序的微观结构）的单壁碳纳米管（SWCNT）-铝（Al）复合材料。拉伸试验表明，部分层压复合材料在三种复合材料中具有最高的屈服强度和拉伸强度，并且几乎具有相同的均匀伸长率，这可以通过Al基体的晶粒细化，SWCNT的有效负载分担和增强部分复合材料的界面-位错相互作用来合理化层压复合材料。
