Fabrication and characterization of Al-matrix composites reinforced whit carbon nanotube

In recent years, there has been increased attention to carbon nanotube-reinforced metal matrix composites due to their high tensile strength as well as exciting thermal and electrical characteristics. In this study, aluminium matrix composite reinforced with multi-wall carbon nanotubes were fabricated by hot pressing. Mechanically milled micron-sized pure aluminium with 0.5wt%, 1wt%, and 2wt% multi wall carbon nanotubes (MWNT), are used to fabricate the samples. In order to obtain optimum pressing condition, mechanical properties (hardness and compressive strength) and densification behaviour of pressed samples at different times and temperatures were measured. Mechanical properties results showed that, carbon nanotubes improve compressive strength and hardness of pure aluminium significantly.
