- Abstract
This paper studies the physical and mechanical properties of pure copper powder with various reinforcement materials at different volume fractions. The used reinforcement materials are carbon nanotubes CNT (0.5-2 wt.%) as nano particles, Al2O3 (1-4 wt.%), and SiC (1-4 wt.%) as micro particles. Various characteristics were evaluated on the composite specimens such as microstructures, density, electrical conductivity, thermal conductivity, hardness, and compression properties to investigate the suitable reinforcement percentage that achieves the best physical and mechanical properties. The micron-sized Al2O3 and SiC and nano sized CNT has shown an enhancement on the mechanical and physical properties of the composite. The electrical and thermal conductivities were evaluated and the results have shown positive enhancements.
