Glass-ceramic matrix composites with dual-layer CVD coated SiC/BN interfaces applied to Nicalon SiC fibers have been developed. These composites have been shown to possess high strength and good fracture toughness to temperatures of 1200{degrees}C. Tensile creep, tensile fatigue, and long-time tensile stress-rupture tests were performed, with the results correlated to the stability of the fiber/matrix interfacial microstructure and chemistry.
