The physics of Carbon Nanotubes has rapidly evolved into a research field since their discovery by lijima [4] in multiwall form in 1991. In this research we have attempted an approach to obtain homogeneously dispersed CNTs in Al powders for preparing Al/CNTs nanocomposite. Ball milled Al and CNTs mixture has been compacted by universal testing machine under the load of 3 tons. Micro hardness and relative density of compacted composites of different weight percentage ratio of CNTs has been measured. By using Vicker hardness test, Optical Microscope, Scanning Electron Microscope (SEM) techniques we analyzed the hardness, micro structures and grain boundaries of casted Al-CNTs composites and compared the hardness of pure Al and CNTs reinforced Al composites at different weight percentages of CNTs. Also we checked the mixing pattern of Al CNT composites using X-Ray Diffraction (XRD) technique.
