Aluminium(Al) is widely utilised in the packaging, transportation, electrical and modern machinery sections because of its low density, high specific strength, excellent corrosion resistance, impressive electrical and thermal conductivity, abundance and recyclability. However, relatively low strength is the most significant challenge for aluminium to be applied in wider area. To solve this problem, carbon nanotube was projected as the most ideal reinforcement due to its incomparable specific strength and elastic modulus, exceptional electrical and thermal conductivity. It is assumed that carbon nanotube can not only strengthen but also introduce various distinctive characteristics into the aluminium matrix to improve its overall properties and performances. In the current research, 0.5 wt. % – 2.0 wt. % of mutil-walled carbon nanotube was ball milled with aluminium powders for 5 – 20h. The microstructure of the as-milled composite powders and as-sintered bulk composite specimens were characterized by particle size analysis, optical microscopy and scanning electron microscopy(SEM). Also, the evolution and dispersion of MWNT were studied by Raman spectroscopy and SEM. Moreover, the as-produced composites were subjected to standard Vickers hardness test and MPIF standard tensile test to investigate the mechanical properties of the composite.
