Investigations on Mechanical Properties of Micro Titanium and CNT reinforced Copper Hybrid Metal Matrix Composites

Abstract: Copper based composites plays a vital role in the field of marine, aerospace, automobile and power sector for making of components like electrical sliding contacts, gears, bearings, bushes, brakes and clutches etc. Even though promising reinforcements are available for the composites, always researchers search for the new combination of matrix and reinforcement for tailored properties and cost effectiveness. CNT is one of the effective reinforcement used in the metal matrix composites by various researches because of its excellent properties. The present work is focused on the preparation of copper/CNTs/Micro-Titanium composite through stir casting technique performance studies of the composite are made on the mechanical properties. The composite prepared with reinforcement such as CNTs and Micro-Titanium of 0.5, 1, 1.5 % and 1, 3 & 5wt. % were studied. The Tensile strength, Compression strength, was found out via experimentation.
