Abstract: The authors have presented a study on the effect of interface thermal resistance on thermal conductivity in carbon nanofiber (CNF) composites. Upon measuring the thermal conductivities of nanocomposites with varying filler concentrations, it was found that the measured thermal conductivities were much lower than those predicted for a nanocomposite in which thermal resistance at CNF-matrix interfaces was negligible. A computational study on interface thermal resistance was then performed. It was found that interface thermal resistance does not significantly alter the thermal conductivity of nanocomposites with continuous nanofibers, but it does have a significant effect on nanocomposites with discontinuous nanofibers in the matrix.
