Patent ID: 7757403

Claim:
A method of manufacturing a hybrid composite journal bearing having a metal housing secured to a stationary part of a bearing system and supporting a journal of the bearing system in a manner that the journal is rotatable, the method comprising the steps of: covering each of opposite ends of a reinforcing unit having a fiber preform and a film with a cover while fitting an O-ring over an outer circumferential surface of each cover to seal the gap between the film and each cover, and placing the reinforcing unit into a metal housing, and securing the reinforcing unit in the metal housing by a support unit; feeding compressed air into the film so that the fiber preform is in close contact with an inner surface of the metal housing; injecting a resin into the reinforcing unit so that the resin is impregnated into the fiber preform; and supplying hot air into the film to harden the fiber preform impregnated with the resin, and removing the support unit and the cover from the metal housing, thus forming a composite liner.
