SYSTEMS AND METHODS FOR PRODUCING A CARBON COMPOSITE MATERIAL

摘要

A carbon/carbon brake disk 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 are disposed in the carbon fiber. In various embodiments, the micro-cracks may be at least partially filled with un-heat-treated carbon 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 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.

主权项

1. A method of manufacturing a carbon/carbon brake disk comprising:
forming a fibrous network from an oxidized carbon fiber precursor; carbonizing the oxidized carbon fiber precursor by heating the oxidized carbon fiber precursor at 1400-2800° C. to form a carbon fiber preform; infiltrating the carbon fiber preform with carbon using chemical vapor infiltration or deposition (CVI/CVD) processing to increase the density of the preform to form a carbon/carbon (C/C) part; heating the C/C part; and performing a final chemical vapor deposition (CVD) process to at least partially fill in a micro-crack in the C/C part at approximately 1000° C.
