“…This result has been encouraged by previous tests that have been performed and have been published in literature, 6,9,10 showing the panel's preliminary weight reduction up to 8% by utilising the SHM approach instead of the traditional design implemented.…”

“…Consequently, it could be possible to improve the composite structure's static strength (compression after impact), for a reduced damage size detection, as illustrated in the simple scheme of Figure 4 and reported in literature. 2,6,9,10 At the same time, it would be possible to reduce the operative costs percentage significantly for airlines by modifying the current damage assessment process from the current two-level approach, visual inspections followed if required by NDI/C-scan, to a single level approach, based exclusively on the interrogation of the offline SHM system.…”

“…This result has already been thoroughly examined, numerically and experimentally in literature. 6,9,10 Hence, the availability of an SHM system, applicable off-line upon the wing skin, able to a detect damage characterised by a severity much lower than the BVID (Table 7) could allow the usage of a higher acceptable compressive design allowable.…”

This detailed study proposes a structural health monitoring system which enables the identification, localisation, and correct measurement analysis, in relation to the damage and debonding induced by low energy impacts within aircraft composite wing panels. The said system has been envisaged as an offline system which aims to be considered as a valid alternative method in relation to the current first two maintenance approach levels: visual inspection, which is to be followed if necessary by ultrasonic scanning techniques. The architecture includes two different technologies which act at different frequency ranges: high-frequency sensors/actuators piezoceramics and low-frequency distributed fiber optic sensors. Experimental and numerical results on small stiffened panels are illustrated in this study, where technological verification and validation have been assessed within a laboratory-controlled environment. In addition, the potential benefit by utilising such techniques within the design of the aircraft composite structures has also been illustrated; in comparison with the current aircraft composite structures, a higher weight saving and better performing structures is foreseen.

“…Similarly to the design process used for composite structures in the aeronautic sector [194], the following sub-sections overview the tools used to design deployable structures, including experimental characterization methods, numerical simulation approaches and design methodologies. For a more detailed review of different folding mechanism concepts and their trade-off, the interested reader is referred to [187] and to [75] for a more detailed classification.…”
