An experiment studied the effect of fiber coatings on the processing, microstructure, and properties of HPZ (silicon carboxynitride) fiber reinforced barium magesium aluminosilicate (BMAS) glass/ceramic matrix composites. Analysis showed that silicon carbide/boron nitride coatings influenced the interfacial bonding strength of the composite, improving its matrix crack deflection and oxidative stability at high temperatures. Coated HPZ fibers exhibited a porous, oxygen rich surface that enhanced their reactivity with the composite at high temperatures. Uniformly coated HPZ fibers produced BMAS matrix composites with improved tensile and flexural properties at temperatures approaching 1200 degrees centigrade. The composites were fabricated by two different methods: hot isostatic pressing or matrix transfer molding.
