ABSTRACT:
A rotor for a gas turbine engine is disclosed. The rotor comprises a glass or glass ceramic matrix reinforced with silicon carbide yarn fiber reinforcement and with silicon carbide yarn reinforcement. The local volume fraction of silicon carbide monofilament increases with increasing radial distance from the inner diameter of the rotor. The rotor exhibits high hoop strength, high oxidation resistance at elevated temperatures and nonuniform elastic modulus which increases with increasing radial distance from the inner diameter of the rotor.
