Abstract

A method for forming a ceramic matrix composite ("CMC") component includes applying a CMC fiber preform to a ceramic core where the CMC fiber preform is formed from a plurality of CMC fiber tows. An interface coating is formed on at least a portion of the plurality of CMC fiber tows before or after the CMC fiber preform is formed from the plurality of CMC fiber tows. A ceramic matrix is formed on the CMC fiber preform with the CMC fiber preform applied to the ceramic core. The CMC fiber preform and the ceramic matrix form a CMC facesheet. A reaction material is located at or adjacent an interface of the CMC facesheet and the ceramic core. The CMC facesheet and the ceramic core are thermally processed to react the interface coating with the reaction material to form a bonding layer at the interface.
