Abstract:

An improved metal, alloy, or intermetallic matrix composite containing carbon reinforcing fibers is formed. The carbon reinforcing fibers are protected from interaction with the matrix material by an inner and on outer barrier layer. The outer layer is any one of the group of stable, non-reactive ceramic materials used to protect fibers, and the inner layer is a ductile, low density, oxygen desorbing rare earth metal. The carbon fibers are particularly useful in forming composites with a titanium aluminide matrix. Patents. aw
