Increasing power densities within microelectronic systems places an ever increasing demand on the thermal management. Thermal interface materials (TIMs) are used to fill air gaps at the interface between two materials, greatly increasing the thermal conductance when solid surfaces are attached together. The last decade has provided significant development on high performing TIMs. This talk presents recent development and progress on metal matrix polymer fiber thermal interface material as a novel approach to address electronics cooling applications. The talk will mainly cover the study of the effect of using polymer fibers, carbon fibers and graphene fibers as the reinforcement in the metal matrix system to enhance mechanical and thermal properties.
