摘要：

A low-viscosity borazine oligomer has been prepared which readily wets carbon fiber layups and converts in very high yield to a stable boron nitride (BN) matrix when heated at 1200-degrees-C. Composites could be prepared after only one or two impregnations which displayed excellent oxidation resistance up to 850-degrees-C. In most cases, the composites showed outstanding mechanical properties after heating at 1200-1500-degrees-C with flexural strength and modulus values as high as 130 ksi and 15 Msi, respectively.
