摘要： A method for forming an oxidation protection system on a composite structure may comprise applying a ceramic layer slurry to the composite structure and heating the composite structure to form a ceramic layer on the composite structure. The ceramic layer slurry may comprise aluminum and silicon carbide powder in a sol. The ceramic layer may comprise alumina, silicon carbide and silicon oxycarbide.

摘要： A method of making a carbon-carbon composite may comprise forming a silicon oxycarbide (SiOC) precursor sol and infiltrating a fibrous preform with the SiOC precursor sol. A SiOC forming heating treatment may be performed on the fibrous preform to form SiOC particles. The fibrous preform may be densified using chemical vapor infiltration to form a densified fibrous preform.
