MANUFACTURE OF CARBON-CARBON COMPOSITE MATERIAL

摘要

A method of making a high strength carbon-carbon utilizing a solid flowable particulate polymer as a pressurizing medium. A resin impregnated carbon fiber reinforced prepreg is disposed in a pressure vessel and the vessel is substantially filled with a solid flowable particulate polymer. The prepreg is exposed to sufficient temperatures and pressures to cure the prepreg to form a carbon-carbon precursor which is subsequently exposed to temperatures and pressures sufficient to post-cure the carbon-carbon precursor. The post-cured carbon-carbon precursor is exposed to temperatures and pressures sufficient to carbonize said post-cured carbon-carbon precursor to form a carbon-carbon composite.
