Research Progress In Oxide/Oxide Ceramic Matrix Composites And Processing Technologies

Oxide/oxide ceramic matrix composites (CMCs) are ideal candidate materials in high-temperature and oxidative environment, due to their low density, high temperature resistance, oxidation resistance, etc, with tremendous potential applications in hot section components of aero engines, such as combustor liners, shrouds, vanes, blades, exhaust nozzle, etc. The research progress of oxide/oxide CMCs was reviewed, including the development of oxide fibers, ceramic matrix, composite material design and processing technologies, with an emphasis on the design of oxide/oxide CMCs, including the selection of interphase and the design of porous matrix, and the processing technologies of CMC materials, especially the prepreg method were introduced in details. Last, the evaluation of oxide/oxide CMCs abroad was summarized, and their future application in hot section components of aero engines was pointed out.
