Metallic doubler repair of composite arcuate flanges

摘要

A method of repairing a composite flange (12) having at least one damaged aperture (14a) comprises attaching a repair structure to the flange (12) using at least one adhesive (28). The repair structure comprises an insert (32) configured to be positioned within the damaged aperture (14a), and a doubler (24) having an aperture (26). The doubler (24) is configured to cover the flange (12) proximate to the damaged aperture (14a). The method includes welding the insert (32) to an inside of the aperture (26) of the doubler (24), prior to attaching the repair structure to the flange (12). The at least one adhesive (28) is then cured to bond the repair structure to the flange (12).
