Seal arc segment with cmc ply cutouts for cooling channels

Abstract

A method of fabricating a seal arc segment includes laying-up at least one radially inner-most ceramic fabric ply on a mandrel, laying-up the at least one discontinuous radially intermediate ceramic fabric ply on the at least one inner-most ceramic fabric ply, the at least one discontinuous radially intermediate ceramic fabric ply having cutout voids, laying-up at least one radially outer-most ceramic fabric ply on the at least one discontinuous radially intermediate ceramic fabric ply with the cutout voids, the radially inner-most ceramic fabric ply, the at least one discontinuous radially intermediate ceramic fabric ply, and the radially outer-most ceramic fabric ply together providing a seal arc segment fiber preform, and densifying the seal arc segment fiber preform with a ceramic matrix material to form a seal arc segment wall of a seal arc segment, wherein the cutout voids define cooling channels in the seal arc segment wall.
