Abstract
A method for forming a ceramic fabric by removing a carbon substrate from a fibrous preform by oxidation. Ceramic coated carbon fibers are laid-up in layers to form a preform. The layers generally have dimensions of from several inches to a few feet depending on the size of the preform. The carbon is exposed at any place where the fiber 'ends' have been made by cutting the preform. The carbon core can be easily and economically oxidized at this point, leaving the ceramic coating as the ceramic fabric.
