Effect of Thermal Interface on Heat Flow in Carbon Nanofiber Composites

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 ...

Temperature dependent ultrasonic and thermo-physical properties of polyaniline nanofibers reinforced epoxy composites

Nanocomposites of polyaniline nanofibers reinforced in epoxy were prepared and their ultrasonic velocities, ultrasonic attenuations, and thermal conductivities were measured over a temperature range of 298-373 K. It was found that the ultrasonic velocity decreased with increasing temperature, but increased with increasing concentration of polyaniline nanofibers in the epoxy matrix. These two trends were opposite for the ultrasonic attenuation, and the thermal conductivity was found to increase with increasing temperature ...

Temperature-dependent thermal properties of a paraffin phase change material embedded with herringbone style graphite nanofibers

The authors outline a method of enhancing the thermal properties of a paraffin phase change material through the addition of herringbone-style graphite nanofibers (HGNFs). It was found that the solid-phase thermal conductivity increased exponentially with the presence of HGNFs; however, a significant increase in the liquid-phase thermal conductivity was not observed until the concentration of HGNFs in the composite PCM reached a point above the percolation threshold. The volumetric heat ...
