Abstract / Hauptanspruch
A modular sensor (10) for damage detection with an optical fiber (FBG sensor (4)) to detect a damage of a composite material (100), having a high level of visibility and manageability, and its manufacturing method is described. A structural composite material (100) embedded with this modular sensor (10) for damage detection is also described.
The modular sensor (10) comprises an optical fiber including a FBG sensor (4), a connector (12) connected to an end portion of the optical fiber, and a tube and/or a film partly covering the optical fiber at a portion where the fiber is drawn out of the composite material (100) in order to prevent breakage of the optical fiber due to stress concentrated at said portion.
