Aluminum matrix composites are widely used in applications demanding high strength and low density materials. The focus of this research is to study the strengthening of a pure aluminum matrix by the addition of multiwalled carbon nanotubes (MWCNTs). The synthesis of the composite was based on a –COOH ligand as a functionalizing agent of the MWCNTs, which were dispersed in isopropanol as solvent media. This was followed by mechanical alloying the MWCNTs with the aluminum matrix via high-energy ball milling. The resulting composite was then compressed into pellets and sintered at 500ºC. Thermal and mechanical properties of these composites were then compared to pure aluminum. The experimental results revealed higher hardness and wear resistance, as measured on the track left on the specimens by a pin-on-disk apparatus.
