Applying this monitoring concept, where incidental impact with known residual strengthcan be tracked at short inspections intervals, may lead to weight saving without compromisingdamage tolerance certification requirements. Integrating this sensing network on real aircraftstructure, like wing or fuselage stiffened panels was demonstrated, together with a contributionto the qualification and certification requirements. It must be pointed out that most of theforeseen works related to embedded optical fibers sensors, have an added complexity for bothmanufacturing and interpretation of the sensor response. Nevertheless the approach of applyingoptical fibers as demonstrated, in terms of low cost manufacturing and robustness, is a stepforward towards the maturation of optical fibers sensing technology for large compositestructures application.
