Abstract
A reinforced oxide-oxide CMC component for a gas turbine engine includes a composite body and a structural element embedded in the composite body, where the composite body comprises a 2D oxide-oxide composite and the structural element comprises a 3D oxide-oxide composite. The 2D oxide-oxide composite includes 2D woven or nonwoven oxide fibers in a first oxide matrix, and the 3D oxide-oxide composite includes 3D woven oxide fibers in a second oxide matrix. The first oxide matrix and the second oxide matrix may comprise the same or a different oxide.
