Abstract
A method for repairing a component that comprises a ceramic matrix composite (“CMC”) material includes forming a repair insert defined by a repair geometry where the repair geometry is based on a repair area of the component, and the repair insert comprises a monolithic ceramic. Inserting the repair insert into the repair area and applying a CMC face sheet to the repair insert. The method further includes bonding the repair insert to the CMC face sheet, the repair insert to the component, and the CMC face sheet to the component. The method also includes thermally processing and densifying at least one of the repair insert or the CMC face sheet in the repair area.
Claims20
A method for repairing a component that comprises a ceramic matrix composite (“CMC”) material, the method comprising:
- forming a repair insert defined by a repair geometry, wherein the repair geometry is based on a repair area of the component, wherein the repair insert comprises a monolithic ceramic;
- inserting the repair insert into the repair area;
- applying a CMC face sheet to the repair insert;
- bonding the repair insert to the CMC face sheet, the repair insert to the component, and the CMC face sheet to the component;
- and
- thermally processing and densifying at least one of the repair insert or the CMC face sheet in the repair area.
A method for repairing a component that comprises a ceramic matrix composite (“CMC”) material, the method comprising:
- defining a repair area of the component, the repair area disposed in a non-sandwich CMC portion of the component;
- forming a repair insert defined by a repair geometry, wherein the repair geometry is based on the repair area, wherein the repair insert comprises a monolithic ceramic;
- inserting the repair insert into the repair area;
- applying a CMC face sheet to the repair insert;
- bonding the repair insert to the CMC face sheet, the repair insert to the component, and the CMC face sheet to the component;
- and
- thermally processing and densifying at least one of the repair insert or the CMC face sheet in the repair area.
A ceramic matrix composite (“CMC”) component, formed by a process of:
- determining a repair geometry for a repair area of the CMC component;
- inserting a preformed repair insert into the repair area, wherein the repair insert comprises a monolithic ceramic;
- applying a CMC face sheet to the repair insert;
- bonding the repair insert to the CMC face sheet, the repair insert to the CMC component, and the CMC face sheet to the CMC component;
- and
- thermally processing and densifying at least one of the repair insert or the CMC face sheet in the repair area.
