| Summary: | The discoveries of carbon nano tube change the direction of the research in the field of fibrous materials
and are attracting much interest as reinforcement to aluminium matrix for carbon nano tubes (CNTs) aluminium (Al)
matrix nano-composite. This is due to unique properties such as high strength, elastic modulus, flexibility and high
aspect ratios. However, the quality of the dispersion is the major concerning factor which determines the
homogeneity of the enhanced mechanical and tribological properties of the composite. This work study the particle
size of aluminium powder in the CNTs-Al nano-composite prepared with different weight percentage of CNT in
aluminium matrix using powder metallurgy route under high energy planetary ball milling operations at different
time intervals. The experimental results showed homogeneous dispersion of CNTs in aluminium matrix at 250 rpm
and the aluminium particle size increased from 78 μm up to 156 μm after just 3 hrs of milling. The preliminary
mixing of CNTs and aluminium powder in a tube via manual shaking and the speed used could be the main
contributing factor in achieving uniform dispersion of CNT in aluminium matrix within short time. |
