Method of manufacturing dense carbon-carbon composite material by:
infiltrating a fibrous preform with pitch to form pitch-infiltrated
preform; carbonizing the pitch-infiltrated preform; injecting resin or
pitch into the preform in a mold; oxygen stabilizing the filled preform
and carbonizing and heat-treating the oxygen-stabilized impregnated
preform; and subjecting the preform to a single final cycle of chemical
vapor deposition. This process reduces densification time as compared to
comparable conventional carbon-carbon composite manufacturing procedures.
