An efficient way to produce a nano composites of pure copper reinforced by carbon nano tubes carboxylic

The paper explains the easiest way to produce a nano-composite, the material of copper reinforced by carbon nano tubes (CNTs), with perfect dispersions of CNTs, to improve and enhance the mechanical properties and reduce the time of fabrication. High energy planetary ball milling device was used to get a homogeneous mixture of copper and CNTs. A pure copper 99.99% was reinforced by Single Wall carbon nano tubes carboxyl (SWCNTs-COOH) and Multi-Wall carbon nano tubes carboxyl (MWCNTs-COOH), with a 6% volume percentage. Acetone was added to CNTs as a solvent and to prevent oxidization and conglomerations in the mixture also it will spread out in the air after finishing ball milling. The microhardness was found (Hv) = (112, 99, 54) kg/mm2 for (SWCNTs-COOH + copper, MWCNTs-COOH + copper, and copper) respectively. Results of the compression tests are showing the enhancement of strength for pure copper to 233.7% with SWCNTs carboxyl and 150% for MWCNTs carboxyl, for tensile test the strength was improved to 268% for SWCNTs-COOH and 166% MWCNTs-COOH.The density was found (7.98, 7.8 and 7.7 g/cm3) for pure copper, SW + Cu and MW + Cu, respectively.
