Integrated device for monitoring the deformations of an electrically insulating part and method of manufacturing such a device

摘要

The device has a Bragg network formed on an optical fiber (2) that includes a mechanical protection sheath made of polyimide material. A cover (13) covers the optical fiber and comprises thermosetting matrix composite materials constituting an electrical insulating piece i.e. wall (1). Another Bragg network is formed in a fiber portion that is covered with elastomer layer. The thickness of the elastomer layer is 0.005 and 0.7 times the diameter of the optical fiber. An independent claim is also included for a method for fabricating an integrated deformation monitoring device.
