Abstract
A method of making a carbon-carbon composite part may comprise fabricating a fibrous preform comprising a fiber volume ratio of 25% or greater, heat treating the fibrous preform at a first temperature, infiltrating the fibrous preform with a first ceramic suspension, densifying the fibrous preform by chemical vapor infiltration (CVI) to form a densified fibrous preform, and heat treating the densified fibrous preform at a second temperature of 1600° C. or greater.
