Abstract

Ceramic matrix composites (CMCs) are one of the candidates for hot components because of their excellent strength and toughness at high temperature. However, the strength and toughness of CMC degrade at high temperature air, because the degradation should be caused by the strong bond between fibre and matrix in an oxidizing atmosphere. A glass-sealing technique was developed in order to improve this anti-oxidation property of CMC. It was found in this paper that a glass-sealed CMC showed the excellent anti-oxidation property. In addition, some trial parts were successfully fabricated by glass-sealed CMC.
