Abstract: Various polyacrylonitrile carbon fillers (Ketjenblack carbon black, Thermocarb synthetic graphite, Fortafil 243 carbon fiber, and Panex 30 carbon fiber) were added to a thermoplastic matrix in the hopes of generating a thermally conductive resin that could be used as bipolar plates in fuel cells. These composites were then tested for through-plane thermal conductivity using the Nielsen model which was a function of the single filler volume fraction. The authors also developed a new empirical model used to measure the in-plane thermal conductivity of composites containing synthetic graphite or carbon fiber.
