Abstract: A coated fiber structure for use in a ceramic matrix composite comprises a fiber and a coating system applied to and circumscribing the fiber. The coating system comprises an interface coating layer in direct contact with the fiber, the interface coating layer comprising one of boron nitride and a boron-doped pyrocarbon, at least one intermediate layer extending coaxially with and in direct contact with the interface layer, the at least one intermediate layer comprising at least one of silicon and boron nitride, and an outer layer extending coaxially with and in direct contact with the interface layer. At least one of the interface coating layer, the at least one intermediate layer, and the outer layer comprises a metallic element.

Abstract: A method of making a ceramic matrix composite component includes arranging a plurality of ceramic-based reinforcements in an array, applying an interface coating to the ceramic-based reinforcements, applying a layer of ceramic-based matrix over the interface coating, and applying a secondary interface coating such that the secondary interface coating is separate and distinct from the layer of ceramic-based matrix. A ceramic matrix composite component is also disclosed.
