Abstract
A carbon-carbon composite is provided comprising a preform containing interwoven mats of graphitized vapor grown carbon fibers. The mat comprises semi-aligned, semi-continuous vapor grown carbon fibers which have been interwoven in situ during growth. The preferred method of producing the carbon-carbon composite includes the steps of densifying the preform by depositing pyrolytic carbon into the interstices of the preform by chemical vapor infiltration or pitch infiltration. The resulting carbon-carbon composite has a thermal conductivity of between about 900 W/m-K and 1000 W/m-K and is useful as a component in electronic devices, aircraft, spacecraft, and other thermal management applications.
