Abstract

Claims (13)

1 . A method of forming a ceramic matrix composite component, comprising:

providing a plurality of ceramic fibers;

disposing a carbon-based layer of an interface coating onto the plurality of ceramic fibers;

disposing a boron-nitride based layer of the interface coating into the carbon-based layer of the interface coating;

arranging the fibers into a preform; and

infiltrating the preform with a ceramic matrix.

2 . The method of claim 1 , wherein disposing the carbon-based layer of an interface coating onto the plurality of ceramic fibers includes applying a binder to the plurality of fibers, and converting the binder into the carbon-based layer.

3 . The method of claim 1 , wherein disposing the carbon-based layer of an interface coating forms a continuous carbon-based layer.

4 . The method of claim 1 , wherein disposing the carbon-based layer of an interface coating forms a discontinuous carbon-based layer.

5 . The method of claim 1 , further comprising:

disposing a second carbon-based layer of a second interface coating onto the boron-nitride based layer;

disposing an additional ceramic layer onto the second carbon-based layer; and

disposing a second boron-nitride based layer of the second interface coating into the additional carbon-based layer.
