Abstract: Conductive carbon fillers (carbon black, carbon fiber, and synthetic graphite particles) were added to Vectra A950RX liquid crystal polymer and the axial and radial thermal conductivities were determined experimentally for each composite. The addition of Thermocarb TC-300 synthetic graphite caused the largest increase in thermal conductivity, with in-plane thermal conductivity values reaching greater than 20 W/m K which is the minimum value for use in fuel cells. Mathematical models were also developed to estimate the in-plane and through-plane thermal conductivities for composites containing synthetic graphite, carbon fiber, and carbon black based on the experimental data.
