The invention relates to a composite material structure (11) which is formed by a plurality of layers (13, 15, 17, 19, 21, 23), including an optical fibre (25) which is used for structural monitoring and which is at least partially embedded in the structure (11). The embedded part of the aforementioned optical fibre is provided with a protective cover (27) in the areas that may require repair. The invention also relates to a method for repairing the embedded optical fibre, comprising the following steps consisting in: identifying the area of the optical fibre that is in need of repair, removing material therefrom until the cover (27) is reached, extracting said area from the structure, removing the protective cover (27), repairing the optical fibre (25), reinstalling the repaired area in the structure, and replacing the material that was removed.
L'invention concerne un structure (11) de matériau composite formée d'une pluralité de couches (13, 15, 17, 19, 21, 23), et qui comprend une fibre optique (25) utilisée à des fins de contrôle de la structure, et qui est, au moins en partie, intégrée dans ladite structure (11). La partie intégrée de ladite fibre optique possède une enveloppe de protection (27) destinée aux zones susceptibles de nécessiter une réparation. L'invention concerne également un procédé de réparation de ladite fibre optique intégrée qui consiste à identifier la zone de la fibre optique nécessitant une réparation, à en éliminer le matériau pour atteindre l'enveloppe (27), à extraire ladite zone de la structure, à retirer le couvercle de protection (27), à réparer la fibre optique (25), à repositionner la zone réparée dans la structure et à restituer le matériau qui a été éliminé.
