CERAMIC COMPOSITE MATERIAL
A ceramic composite material is comprised of a fabric of fibers of an inorganic substance; and a matrix for combining the fibers. The matrix consists essentially of a ceramic. The matrix is formed by burying the fabric in a mixture of a powder of carbon, a powder of silicon and a medium including an organic solvent, producing an oscillation in the mixture to impregnate the fabric with the mixture, and calcining the fabric impregnated with the mixture.
