Ceramic composite articles having high flexural and tensile strength are produced by introducing multiple layers of a ceramic matrix material onto a ceramic reinforcement fabric. Crack propagation in the resulting structure is inhibited by applying refractory interface layers intermediate successive ceramic matrix layers. Such ceramic composite articles are particularly useful for high temperature applications requiring a high degree of strength, such as rocket motor insulation and turbine blades, combustion chambers, and after burners for jet motors. |
