Polymer composites with high thermal conductivity offer new possibilities for thermal management in electric systems. An approach of current interest to improve thermal conductivity of polymer composites is the addition of hybrid nano and micro fillers with high thermal conductivity. The objective of this paper is to study thermal conductivity of the epoxy composites with nano and micro fillers by using Digimat-FE software. Representative volume element (RVE) models with random close-packed structures of nano and micro fillers were obtained, and finite element analysis was performed to evaluate thermal conductivity of polymer composites. Effect of addition of alumina nanowire to closepacked structure of micro fillers on the thermal conductivity of polymer composites was discussed.
