Abstract
A method is described for introducing cooling cavities into CMC components beneath flanges such as T-shaped flanges within the CMC components. During layup, preform is made having flanges formed from a Y-shaped weave in which plies of woven ceramic fiber tows form a radial flange section extending from a base of the preform and two bifurcated arms. The plies of the two bifurcated arms and plies of the base form a cooling cavity having a triangular cross section beneath the flange. Cooling fluid inlet passages are provided to permit cooling fluid to enter the cooling cavity and thereby cool the internal region of the CMC component to reduce formation of thermal stresses.
