Abstract

A carbon/carbon brake disk 210 is provided. The carbon/carbon brake disk may comprise a carbon fiber, wherein the carbon fiber is formed into a fibrous network, wherein the fibrous network comprises carbon deposited therein. The carbon fiber may undergo a FHT process, wherein micro-cracks 215 are disposed in the carbon fiber. In various embodiments, the micro-cracks 215 may be at least partially filled with un-heat-treated carbon 230 via a final CVD process, wherein the final CVD process is performed at a temperature in the range of up to about 1,000°C (1,832°F) for a duration in the range from about 20 hours to about 100 hours. In various embodiments, the un-heat-treated carbon 230 may be configured to prevent oxygen, moisture, and/or oxidation protection systems (OPS) chemicals from penetrating the carbon/carbon brake disk. In various embodiments, the final CVI/CVD process may be configured to increase the wear life of the carbon/carbon brake disk.
