1. A method of manufacturing a carbon structure, comprising:
infiltrating the carbon structure with a silicon oxycarbide (SiOC) precursor sol;
densifying the carbon structure by chemical vapor infiltration (CVI) to form a carbon and ceramic matrix composite material, the carbon and ceramic matrix composite material comprising between 0% and 15% by weight of a plurality of ceramic particles, wherein densifying the carbon structure includes adjusting a temperature gradient across the carbon structure; and
establishing a first thermal gradient in a process furnace, a first temperature of a first surface of the carbon structure being higher than a second temperature of a second surface of the carbon structure.
