Description

One major concern about ceramic matrix composites (CMC) is their high temperature stability, especially in an oxidizing environment. In general CMC materials are composed of matrix, fiber, and interphase layers (mainly fiber coatings and/or reaction product layers). It is known [1,2] that the properties of CMC materials are dominated by the interphase. However, this interphase often suffers from oxidation reactions caused by diffusion of oxygen through the matrix [1,3]. As a result desirable properties are not retained.
