ABSTRACT:
A hybrid CMC laminate is comprised of alternating layers of dense ceramics and fiber reinforced CMCs. The strategy involves the use of strong and stiff ceramics in order to delay the onset of cracking within the CMC layers. To provide protection from mechanical abrasion, improve thermal conductivity and inhibit oxygen ingress into the CMC layer, ceramic layers are placed on the outer surfaces of laminate. The laminate is produced by stacking alternating layers of dense ceramic and binderless layers of fiber reinforced CMCs, and then hot-pressing them together. The volume fractions of the constituent layers and the fiber architecture can be readily varied through this process. Reinforcement architecture (unidirectional vs. crossply) and the relative volume fractions of the phases effects the tensile and flexural properties of the laminates.
