Fabrication and Characterisation of Cu-CNT Nanocomposites

Copper (Cu) and its alloys are used because of its high electrical and thermal conductivity coupled with strength. Carbon nanotubes (CNTs), since their appearance and for their unique properties such as exceptionally small diameters and high Young’s modulus, tensile strength and high chemical stability, are considered to be an attractive reinforcement material for lightweight and high-strength nanocomposites. The powder metallurgy method allows nanocomposite materials to be produced by sintering a mixture of powders. The powder metallurgy method is to fabricate a Cu/CNT nanocomposite. In this work, a nanocomposite material made of copper is reinforced by multi-walled carbon nanotubes by weight ratio. Sintering is the important process in this method; it is the process whereby powder compacts are heated so that adjacent particles fuse together. In this process, the mechanical properties of the nanocomposites are calculated for different weight percentage of carbon nanotubes. This investigation deals with the study of the effect of CNT materials on the mechanical and its microstructure.
