Abstract
A ceramic matrix composite includes a plurality of ceramic fibers and an interface coating disposed on the plurality of ceramic fibers. The interface coating includes a carbon-based layer disposed on each ceramic fiber of the plurality of ceramic fibers and a boron-nitride based layer disposed on the first carbon-based layer. The ceramic matrix composite also includes a ceramic matrix surrounding the plurality of ceramic fibers. A ceramic matrix composite and a method of forming a ceramic matrix composite component are also disclosed.
Claims5
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.
