Characterization of Copper Carbon Composites Manufactured Using the Electroless Precipitation Process

Abstract

Copper-carbon composites with various copper nano-particulates volume fractions were manufactured using electroless precipitation process. Composites with 10% and 20% carbon volume fractions and copper samples were sintered at two different sintering temperatures 700° and 800°C. The microstructure was studied using high resolution optical scanning investigations. Experimental results indicate that the coefficients of thermal expansion and electrical resistivity intensified with the escalation of the carbon volume fraction in the composites. However, the stress-strain response was found to decrease with the increase of carbon volume fraction in the copper-carbon composites.
