Abstract

A composite composed of SiC filler and Si–B–C–N matrix retained its properties even after heat treatment at 2000 °C for 10 h in Ar. The weight loss of the composite was less than 2% at 2100 °C. The composite showed excellent resistance to creep at 1400 °C in air and was strongly oxidation resistant at least up to 1450 °C. The material can be used for the fabrication of fiber-reinforced ceramic matrix composites with high thermal stability.
