Abstract
A ceramic matrix composite (“CMC”) component includes a ceramic core comprising one or more interlocking elements. A CMC facesheet is positioned against a surface of the ceramic core and in mechanical engagement with the one or more interlocking elements to secure the CMC facesheet to the ceramic core. At least a portion of CMC facesheet is disposed between at least one interlocking element of the one or more interlocking elements and the surface.
Claims20
A ceramic matrix composite (“CMC”) component, comprising:
- a ceramic core comprising one or more interlocking elements;
- and
- a CMC facesheet positioned against a surface of the ceramic core, the CMC facesheet in mechanical engagement with the one or more interlocking elements to secure the CMC facesheet to the ceramic core, wherein at least a portion of CMC facesheet is disposed between at least one interlocking element of the one or more interlocking elements and the surface.
A method for forming a ceramic matrix composite (“CMC”) component, the method comprising:
- forming one or more interlocking elements in a ceramic core;
- and
- forming a CMC facesheet against a surface of the ceramic core that engages the one or more interlocking elements to secure the CMC facesheet to the ceramic core, wherein at least a portion of the CMC facesheet is disposed between at least one interlocking element of the one or more interlocking elements and the surface.
A method for forming a ceramic matrix composite (“CMC”) component, the method comprising:
- additively manufacturing a ceramic core to include one or more interlocking elements;
- applying a CMC fiber preform to a surface of the ceramic core;
- and
- forming a ceramic matrix onto the CMC fiber preform, wherein the ceramic matrix and the CMC fiber preform form a CMC facesheet, and wherein at least a portion of the CMC facesheet is disposed between at least one locking element of the one or more locking elements and the surface.
