Abstract: Inorganic reinforcing fibers provided with a multilayer protective coating comprising a boron nitride sublayer and an oxide-based overcoating of alumina or synthetic mica, and fiber-reinforced ceramic matrix composite products incorporating the protectively-coated fibers, are disclosed. The fibers offer improved oxidation resistance and good compatibility with oxide-based glass and glass-ceramic composite matrix materials.
