Descripción
Delamination is the most characteris tic damage found in composite materials. Low velocity impacts may lead to delamination onset, likely to occur during manufacturing process es or in operating service life. Furthermore, areas near the free-edge of the structures, as well as ply drop off and integrated reinforcements have demonstrate a high vulnerability to impacts. This paper focuses on the delamination detection based on an embedded or fixed fiber optic network in a composite laminate. The sensor network uses the Rayleigh scatter ing through an Optical Backscatter Reflectometer (OBR) that it obtains a conti nuous strain monitoring on a bare opical fiber. For this purpose, several optical fibers were a ttached on the structure surface close to the free edge of the specimens in order to identify the first-ply failure and the delamination growth. Experimental results were compared to an ultrasonic C-Scan inspection which present a good agreement with the data of sensor network.
