A randomly damaged area of a one-piece composite component of an aircraft is repaired according to a method herein. The damaged area covers skin and underlying stiffening substructure of the component. The method includes generating a design of a customized composite replacement panel for replacing the damaged area. The design includes replacement skin and underlying co-cured replacement stiffening substructure. The method further includes fabricating the composite replacement panel according to the design. Une zone endommagée aléatoirement dun composant composite dune pièce dun aéronef est réparée selon la méthode des présentes. La zone endommagée touche le revêtement et la sous-structure de renforcement sous-jacente du composant. La méthode comprend la génération dun modèle de panneau de remplacement en composite personnalisé pour remplacer la zone endommagée. Le modèle comprend un revêtement de remplacement et une sous-structure de renforcement de remplacement sous-jacente co-durcie. La méthode comprend en outre la fabrication du panneau de remplacement composite selon le modèle.
