▎ 摘　　要

Copper-reduced graphene oxide composites having good anisotropic thermal conductivity and hardness values fabricated via flake powder metallurgy route. SEM was performed to examine the microstructure of powders and also different composites. Anisotropic thermal diffusivity and micro-hardness test were performed to examine the different concentrations and particle sizes effect on composites. The best thermal conductivity ratio was obtained at 5 wt% reduced graphene oxide ( rGO) at 9.5 mu m particle size. Moreover, the extraordinarily high value of hardness ( 85 HV) copper-reduced graphene oxide composite was acquired at 3 wt% rGO with 9.5 mu m particle size.
