Abstract:
Carbon fibers produced from PBO develop three dimensional ordering that is better than other polymeric precursors, such as PAN. The low electrical resistivities achieved by PBO-based carbon fibers implies high thermal conductivity. Stabilization of the polymer fiber is not needed to obtain the 3-D ordering and low electrical resistivity. This ability to develop into a high thermal conductivity fiber without stabilization may be particularly attractive for use in carbon-carbon composites. The elimination of one carbonization cycle in the manufacture of CC composites may reduce the production cost.
