Abstract
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.

A method of making a carbon-carbon composite, comprising:
- forming a silicon oxycarbide (SiOC) precursor sol;
- infiltrating a fibrous preform with the SiOC precursor sol;
- performing a SiOC forming heating treatment on the fibrous preform to form SiOC particles;
- and
- densifying the fibrous preform by chemical vapor infiltration (CVI) to form a densified fibrous preform.
