Matrix-Enabled Damage Tolerance in Oxide CFCCs

Abstract

The program has focused on the mechanics of deformation and fracture of a family of porous-matrix all-oxide continuous fiber ceramic composites (CFCCs). The activities have led to substantive developments in the mechanistic understanding of: (1) mechanical properties and thermal stability of porous mullite/alumina matrices; (2) strength, fracture resistance and notch sensitivity of porous-matrix composites; and (3) stability and performance of oxide composites in gas turbine combustion environments. Models to describe the pertinent phenomena have been developed and validated.
