This invention relates to a composition and method of inhibiting catalyzed oxidation of carbon-carbon composites. The invention includes compositions, capable of impregnating carbon-carbon composites. The invention also includes a method of inhibiting catalyzed oxidation of carbon-carbon composites comprising the steps of treating a carbon-carbon composite with the catalyzed oxidation inhibiting aqueous mixture, and heating the treated carbon-carbon composite to a temperature sufficient to remove water. Articles, including friction brakes, made by this method are also part of this invention. Brake lugs, and other exposed areas of aircraft braking systems have improved resistance to catalyzed oxidation.
