摘要
Carbon coated carbide fibres (30) are arranged in a predetermined pattern and shape around a silicon carbide coated (36) graphite insert (34). Silicon carbide is infiltrated into the silicon carbide fibres (30) to produce a SiC/SiC composite component (40). The SiC/SiC composite component (40) is coated with glass (42) and is then heated in air to burn out the graphite insert (34) to form a hollow glass coated SiC/SiC composite component. Suitable for producing hollow SiC/SiC composite turbine blades or vanes. IMAGE
