Summary

The fiber-matrix interface of Nicalon™/SiC composites with “weak” and “strong” fiber bonding was characterized by means of single-fiber push-out tests. It was found that the stress vs. fiber-end displacement push-out curves for the composites with “strong” fiber bonding were increasingly stiffer, in contrast to the traditional increasingly compliant curves obtained for composites with “weak” fiber bonding as predicted by standard interfacial models. These results are analyzed in light of the superior mechanical behavior of the composite with “strong” fiber bonding. The philosophy for developing ceramic matrix composites with “weak” fiber bonding is revisited.
