Abstract
Carbon coated carbide fibers are arranged in a predetermined pattern and shape around a silicon carbide coated graphite insert. Silicon carbide is infiltrated into the silicon carbide fibers to produce a SiC/SiC composite component. The SiC/SiC composite component is coated with glass and is then heated in air to burn out the graphite insert to form a hollow glass coated SiC/SiC composite component. The method is suitable for producing hollow SiC/SiC composite turbine blades or vanes.
