Abstract: Adding conductive fillers to polymer resins improves the thermal conductivity of the polymers. In this study, Thermocarb TC-300 synthetic graphite and Fortafil 243 carbon fiber were added to Vectra A950RX liquid crystal polymer (LCP) to produce anisotropic single and multiple filler composites. A Hot Disk Thermal Constants Analyzer measured the thermal conductivity of the composites using the transient plane source (TPS) technique. The formulations that contained Thermocarb fillers had higher in- and through-plane thermal conductivities than those containing Fortafil, which was likely due to the higher thermal conductivity of the synthetic graphite particles. The theoretical models that were computed showed good agreement with the experimental results.
