Abstract

A hybrid sandwich ceramic matrix composite (CMC) may comprise a first facesheet, a second facesheet, and a core between and bonded to both of the first facesheet and the second facesheet. The first facesheet and the second facesheet may each include filaments in a ceramic matrix. The hybrid sandwich CMC may be configured for exposure to a thermal gradient in which the first facesheet is exposed to a higher temperature environment than the second facesheet. The first facesheet and the second facesheet may have at least closely matching coefficients of thermal expansion, and the first facesheet may have a higher compressive strength than the second facesheet.
