Abstract: Two different types of polyacrylonitrile carbon fibers (Fortafil 243 and Panex 30) were added to thermoplastic matrix (Vectra A950RX Liquid Crystal Polymer) in order to generate carbon fiber/liquid-crystal polymer composites. The in plane and through-plane thermal conductivities of these composites were then evaluated and compared to values generated from a theoretical model, with good agreement. Panex 30 gave higher in-plane thermal conductivity than Fortafil 243 for all volume fractions studied.
