Abstract
A method of manufacturing a hybrid structure () having a layer of CMC material () defining an interior passageway () and a layer of ceramic insulating material () lining the passageway. The method includes the step of casting the insulating material to a first thickness required for effective casting but in excess of a desired second thickness for use of the hybrid structure. An inner mold () defining a net shape desired for the passageway remains in place after the casting step to mechanically support the insulating material during a machining process used to reduce the thickness of the insulating material from the as-cast first thickness to the desired second thickness. The inner mold also provides support as the CMC material is deposited onto the insulating material. The inner mold may include a fugitive material portion () to facilitate its removal after the CMC material is formed.
