- Summary
- Some of the engineering limitations of ceramic matrix composites in high-temperature applications are reviewed in terms of fundamental properties. The issues associated with toughness control in the regimes where fiber pullout is not extensive are discussed. Toughening will decrease with increasing temperature because fiber strength decreases and interfacial sliding resistance increases. The temperatures regime where reinforcement fibers become creep limited, as opposed to strength limited, will influence design considerations. Matrix cracking becomes an important high temperature design limiting parameter, particularly where oxygen can rapidly gain access to bridging fibers. Even the direct permeation of oxygen through uncracked matrices may be sufficient to internally degrade fibers and limit performance in some systems.
