Abstract
The invention provides for oxidatively resistant surface coated carbon/carbon composites and other graphite-like material, a method for the preparation of these materials, and their use in high temperature applications, preferably in brake for airplanes. The surface coated carbon/carbon composite or graphite-like material, which is resistant to oxidation at high temperatures comprises a fiber-reinforced carbon/carbon composite or graphite having a First Coating (A) of silicon and/or silicon carbide, and a Second Coating (B) comprising a material containing phosphorus chemically bound to oxygen which is chemically bound to silicon.
