Summary

Differences in interphase development and strength between Nicalon and Tyranno-fiber-reinforced ceramic matrix composites using the same matrix of ZrTiO4 were assessed. The microstructure and interphase development were analyzed using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and analytical electron microscopy (AEM). Tyranno composites developed thinner interphases due to differences in the structure and chemistry of the starting fiber resulting from the addition of Ti to the starting polymer precursor. BN-coated fiber composites developed a thicker interphase layer due to incorporation of O in the supplied BN-coated fibers. Tyranno composites were weaker due in part to fiber clustering problems.
