Summary

We consider an oxide-oxide composite consisting of 2D textile reinforcement (Nextel 720 fibers) in a matrix consisting of alumina particles, voids, inherent cracks due to processing conditions, and a silica bonding agent. The analytical approach follows a building block scenario in which the microstructure is homogenized at various levels. Predicted quantities include the thermo-mechanical effective moduli in the presence of processing induced damage. The numerical predictions are compared to experimental results for the composite material to assess the implications of the assumptions invoked in the model.
