Abstract
A carbon/carbon part and a process for making carbon/carbon parts is provided. The process involves forming steps, carbonization steps and densification steps. The forming steps may include needling fibrous layers to form fibers that extend in three directions. The carbonization steps may include applying pressure to increase the fiber volume ratio of the fibrous preform. The densification steps may include filling the voids of the fibrous preform with a carbon matrix.
