鈥俁eviews on Advanced Materials Science 52(1):126-133 路 December 2017This 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
