Abstract
A blade outer air seal arc segment includes a ceramic matrix composite body that defines a core gaspath side, a non-core gaspath side opposite the core gaspath side, a forward end, an aft end, and circumferential sides. The ceramic matrix composite body has first and second flanges on the non-core gaspath side. The ceramic matrix composite body is comprised of fiber plies disposed in a ceramic matrix. The fiber plies include flange fiber plies that have a +/−15-75 degree ply layup arrangement.
