C-fiber/oxide matrix composites are attractive for high temperature applications because oxide matrices can possibly provide protection against oxidation and because of excellent mechanical properties of carbon fibers up to very high temperatures. Oxidation can still occur in such composites because oxygen can diffuse in through the oxide by solid state diffusion and oxidize carbon forming carbon monoxide. This talk will address the problems caused by CO, in particular the conditions under which CO gas bubbles and/or cracks can form in the oxide matrix. Also included will be the results of oxidation experiments on carbon samples buried deep within Al2O3 and Y2O3.
