Non-porous metal oxide-coated carbonaceous fibers capable of withstanding chemical degradation at temperatures above 1600°C and that are particularly useful in the construction of ceramic or metal composites without carbon-carbide hypereutectic formation or micro-cracking in metal and ceramic matrix composites, respectively, but with good interfacial bonding, thereby allowing the same to be favorably employed in space reentry vehicles, heat shields, high-performance aircraft, internal combustion engines, and the like. |
