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....
Synthetic graphite particles were added to a liquid crystal polymer and then these composites were tested for through-plane and in-plane thermal conductivity using the TPS method. The authors expanded on an empirical model created to determine the relationship between thermal conductivity and volume percent of filler. This empirical model can now be used to approximate the in-plane thermal conductivities for a range of applications....
