Summary

The strength and toughness of BN-coated Tyranno' and Nicalon SiC fiber/ZrTiO4 composites were tested in air at temperatures up to 1200°C. The Tyranno composite was exposed to high temperature soaks in air or Ar. Excellent mechanical properties were maintained up to 1000°C where oxidation of the BN debond layer occurred. At 1200°C the Tyranno composite oxidized to form a protective layer inhibiting further oxidation.
