Abstract
Inorganic reinforcing fibers comprising hybrid BN--C protective coatings containing up to 12% by weight of hexagonal (graphitic) carbon dissolved in the BN matrix but being essentially free of undissolved pyrolytic and graphitic carbon secondary phases, and fiber-reinforced ceramic matrix composite products incorporating the protectively-coated fibers, are disclosed. The fibers resist oxidation and provide good bonding interface characteristics when disposed in ceramic encapsulating materials, such that the composite products exhibit excellent resistance to high temperature embrittlement.
