Abstract：Carbon nanotube-reinforced aluminium matrix composite (CNT/Al) is an innovative lightweight structural material for aerospace and weapons equipment. Great progress has been made in its preparation and application technology in recent years. This paper has summarized the preparation technologies of CNT/Al composite and their engineering bottleneck. The preparation technology suitable for industrial production that combined flake powder metallurgy with the element alloying method was highlighted. The mechanical properties and the damping capacity at room temperature and high temperature for the large-size CNT/2A12Al composite were introduced. The strengthening and toughening mechanism and the strategies to simultaneously enhance strength and ductility were reviewed, such as CNT intragranular dispersion architecture and heterogeneous grain size architecture. The deformation processing, application technology of large-size CNT/Al composites, and the application prospect and future research focus were also discussed.
