  • Device and method for repairing a damaged zone of an intermediate layer of a multilayer structure by way of deformable corrugated rings
    Patent number: 9517536
    Abstract: A device for repairing a damaged zone in a first cavity, with a first diameter, of an intermediate layer interposed between two layers that have a second cavity with a second diameter smaller than the first diameter. The device includes a stop that forms an abutment at the interface between the first cavity and one of the second cavities, a ring having a deformable corrugated shape, an initial inside diameter, an initial outside diameter smaller than the second diameter, and being positioned in the first cavity, a deformation element having an elastically variable outside diameter initially smaller than the initial inside diameter of the ring, and a tool being able to increase the outside diameter of the deformation element so that it deforms the ring in the first cavity in order to reduce the difference between the first and second diameters.
