The invention relates to a composite material structure (11) which is formed by a plurality of layers (13, 15, 17, 19, 21, 23). The invention includes: an optical fibre (25) which is used for structural monitoring and which is at least partially embedded in a surface layer (13) of the structure (11); and means for insulating the areas of the optical fibre (25) that may require repair in relation to the surface layer (13) containing same, said means taking the form of a protective cover (27) and upper and lower separator films (31, 33) in particular. The invention also relates to a method for repairing the aforementioned areas of the optical fibre, comprising the following steps consisting in: removing the protective cover (27) and the upper separator film (31), extracting the area from the structure, repairing the optical fibre, reinstalling the repaired area, and providing a new protective cover (27).
L'invention concerne une 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 une couche superficielle (13) de ladite structure (11), et des moyens d'isolation des zones de la fibre optique (25) susceptibles de nécessiter une réparation au niveau de la couche superficielle (13), dans laquelle sont notamment intégrées une enveloppe de protection (27) et des pellicules de séparation supérieure et inférieure (31, 33). L'invention concerne également un procédé de réparation desdites zones qui consiste à éliminer l'enveloppe de protection (27) et la pellicule de séparation supérieure (31), à extraire ladite zone de la structure, à réparer la fibre optique, à repositionner la zone et à fournir une nouvelle enveloppe de protection.
