Summary

Recent work has pointed out the contribution of interface opening strength (IOS) in the deviation of matrix cracks and in the mechanical properties of fiber reinforced ceramic matrix composites.

In the present paper, an approach to IOS determination is proposed. It is based on four–point bending tests on notched bi–layer specimens. IOS is extracted from the force– displacement behavior, using a finite element analysis of the stress state at notch tip. Various bi–layer test–specimens were prepared and tested. IOS estimations were then compared to predictions by a model of debonding based on the Cook and Gordon's mechanism.
