Ceramic composite component

A method of forming a ceramic composite component, comprising:

• coupling a ceramic matrix composite (CMC) structure to a ceramic core structure, wherein the ceramic core structure comprises a plurality of hollow cells defined by a plurality of walls extending from a first side of the ceramic core structure to a second side of the ceramic core structure opposite the first side, and wherein the CMC structure comprises a plurality of CMC plies defining a first side of the CMC structure and a second side of the CMC structure opposite the first side of the CMC structure;
• bonding a first CMC face sheet to the first side of the ceramic core structure and the first side of the CMC structure;
• bonding a second CMC face sheet to the second side of the ceramic core structure and the second side of the CMC structure;
• and
• densifying and bonding together the first and second CMC face sheets, the ceramic core structure, and the CMC structure,
• wherein coupling the CMC structure to the ceramic core structure comprises disposing at least a portion of the CMC structure within a recessed portion extending inward from a perimeter sidewall of the ceramic core structure.

A ceramic composite component, comprising:

• a first ceramic core structure having a plurality of hollow cells defined by a plurality of walls extending from a first side of the first ceramic core structure to a second side of the first ceramic core structure, the second side opposite the first side;
• a second ceramic core structure extending from the first ceramic core structure and defining an edge of the ceramic composite component, the second ceramic core structure comprising a solid ceramic core structure;
• a first CMC face sheet bonded to the first side of the first ceramic core structure and at least a first portion of the second ceramic core structure;
• and
• a second CMC face sheet bonded to the second side of the ceramic core structure and at least a second portion of the second ceramic core structure,
• wherein the first ceramic core structure defines a recessed portion extending inward from a perimeter sidewall of the first ceramic core structure and configured to receive at least a portion of the second ceramic core structure.
