    Abstract: Process for producing a ceramic composite structure (10) includes impregnating a reinforcing material with a suitable precursor slurry composition (110) including thermosetting resin, a suitable curing agent, a ceramic component, a carbonaceous solids component, and optionally, a suitable solvent. Exemplary thermosetting resins include polyesters, vinyl esters, epoxy resins, bismaleimide resins, and polyimide resins. The carbonaceous solids component provides a suitable amount of carbon char upon pyrolization. The preform may be dried prior to curing to remove solvents and thereby provide a working material comprising up to 70 volume% solids. The preform is cured (120), pyrolized (130), and infiltrated with molten silicon (140) to form a composite article. The thermosetting resin is selected for processibility, green strength, and relatively fast cure cycle.

    Abstract: An improved carbon-carbon composite and method of preparation. Thp carbon-carbon composite comprises a plurality of carbon fibers agglomerated and joined or consolidated together typically into a preform. The carbon fibers are impregnated with pitch prior to carbonization in order to enhance the density of the carbonized preform. The method comprises adding pitch powder to a preform and melting the pitch powder so as to uniformly impregnate the carbon fibers, thus enhancing the carbonized density of the preform.
