Beschreibung
Zusammenfassung:	A disclosed method is suitable for repairing a blade of a turbomachine rotor, particularly a turbomachine fan, that includes a vane made from an organic-matrix composite and a metallic shield that is bonded to a leading edge of the vane and has a damaged region. The method includes steps of resetting the leading edge of the vane cooling the entire vane, followed by a step of refilling the damaged region by adding a metallic material to this damaged region and melting the material using a laser, and a step of tailoring the damaged region by machining the molten material.
