Method for forming a ceramic matrix composite component

A method of forming a ceramic matrix composite (CMC) component, comprising:

• laying up one or more first CMC plies to form at least one wall;
• densifying the one or more first CMC plies;
• forming one or more bores extending through the at least one wall, at least one bore of the one or more bores comprising an inlet end proximate a first side of the wall and an outlet end proximate a second side of the wall;
• disposing one or more second CMC plies on at least a portion of the second side to cover the outlet end of the at least one bore;
• densifying and bonding the one or more second CMC plies to the at least one wall;
• and
• applying an environmental barrier coating on at least a portion of the one or more second CMC plies covering the outlet end of the at least one bore.

A ceramic matrix composite (CMC) component, comprising:

• a ceramic structure defining at least one wall disposed between a hot side portion of the CMC component and a cold side portion of the CMC component, wherein the at least one wall includes at least one bore having an inlet end and an outlet end, the inlet end being open on the cold side portion;
• one or more densified CMC plies bonded to at least a portion of the hot side portion covering the outlet end;
• and
• an environmental barrier coating disposed on at least a portion of the hot side portion including at least a portion of the one or more densified CMC plies covering the outlet end of the at least one bore.
