View the Complete Application at the US Patent & Trademark Office
A gas turbine seal assembly includes a gas turbine component and a gas turbine seal component contacting the gas turbine component to form a seal between the two components. The gas turbine seal component includes ceramic matrix composite plies bonded together to form the ceramic matrix composite component. A bond-inhibiting coating on a non-bonding portion of a first surface of one of the ceramic matrix composite plies prevents bonding between the non-bonding portion of the first surface and a second surface of a neighboring ceramic matrix composite ply. At least one bonding portion of the first surface lacking the bond-inhibiting coating is bonded to the second surface. A method of forming a ceramic matrix composite component includes selectively applying a bond-inhibiting coating to a non-bonding portion of a first surface of a ceramic matrix composite ply and bonding the ceramic matrix composite plies together.
