In this study, reinforcements of carbon nanotubes (CNTs) and silicon carbide particle (SiC_p) in CNTs-SiC_p reinforced aluminum matrix nanocomposites (AMNCs) are studied. The tensile strength of 0.5CNTs-0.5SiC_p/Al increase by 94% compared with pure Al reaching 247 MPa, it also has a lifting of 14% and 56% compared with 1.0CNTs/Al and 1.0SiC_p/Al. CNT-SiC_p reinforcements have the synergistic enhancement effect of 1 + 1 > 2 in tensile strength. It is found that SiC_p as a dispersed particle around CNTs can inhibit and delay the pulling out and peeling of CNTs to further enhance the strengthening effect of CNTs by pinning effect. Between CNTs and Al matrix, there is a nano-scale reaction transition layer which improves the mechanical properties of AMNCs by strengthening the interfacial bonding. The existences of SiC_p inhibit the excessive reaction of the interface, when the tensile strength of AMNCs increases compared with pure Al, the elongation and conductivity have similar maintaining.

在这项研究中，碳纳米管（CNT）和碳化硅颗粒（SiC构成增援_p中的CNT-SiC）的_p增强铝基复合材料（AMNCs）进行了研究。0.5CNTs-0.5SiC _p / Al的拉伸强度与纯Al相比达到247 MPa，提高了94％，与1.0CNTs / Al和1.0SiC _p / Al相比，其拉伸强度也分别提高了14％和56％。CNT-SiC _p增强材料在拉伸强度方面具有1 + 1> 2的协同增强作用。发现SiC _p由于碳纳米管周围的分散颗粒可以抑制并延迟碳纳米管的拔出和剥离，从而通过钉扎效应进一步增强碳纳米管的增强作用。在碳纳米管和铝基体之间，存在一个纳米级反应过渡层，该过渡层通过增强界面键合来改善AMNC的机械性能。SiC _p的存在抑制了界面的过度反应，当AMNCs的拉伸强度比纯Al更高时，伸长率和电导率具有相似的维持率。
