Abstract:
An air-cooled component comprising:at least one cooling passage defined by a surface of the component, at least a portion of the surface being defined by a composite material comprising at least first and second sets of tows woven together within a matrix material, the tows of the first set being side-by-side to each other, the tows of the second set being side-by-side to each other and transverse to the tows of the first set, the tows of the second set passing over and under tows of the first set; and a surface feature integrally defined at the surface of the cooling passage by at least a portion of at least one of the tows of the second set that passes over an insert member disposed between at least two adjacent tows of the first set of tows, the insert member having a cross-sectional size larger than the adjacent tows of the first set so that the insert member causes the portion of the at least one tow of the second set to project into the cooling passage relative to an immediately surrounding surface region of the surface.
