“…Although the value is lower than that of the standard A or D components, it is still high enough to evaluate the preliminary performances of the LSP systems. Indeed, according to Katunin [22] the internal aircraft manufacturer regulations and statistical reports indicate that the most common natural lightning discharges are in the range of 5-10 kA. In addition, in some other works such as that of Feraboli et al [23], Yokozeki et al [9], Kamiyama et al [24] and Xia et al [18], lightning emulation experiments were conducted employing discharges of lower currents than those stated in the ARP directive, considering that it was sufficiently high current anyways for inflicting damage to coupon-level specimens (much smaller than full-size aircraft parts).…”

“…The reduced electrical conductivity of the composites represents one inherent shortcoming in their use for aeronautic primary structures. This fact has raised concern over the performance of the composite structure during a lightning strike event that usually takes place during take-off and landing of an aircraft, as well as during passing through the storm clouds [11,12]. Lightning generally strikes a geometrically extremal point of an aircraft (like radome, wing tips, etc.)…”

Polymer-matrix composites containing conductive nanoparticles are a potential means for achieving an appealing combination of multifunctional properties for their use as structural parts in the aerospace field. Carbon nanofibers (CNFs) have been being looked forward to as the next generation of new and avant-garde aircraft structures because they are exceptionally coveted competitor materials to replace traditional metal components for lightning strike protection. In this regard, nanocomposites at low concentration of CNFs ranging from 0.05% up to 2% by wt to impart electron conduction in tetrafunctional epoxy resin have been prepared and characterized. The aim of this work concerns the use of Tunneling AFM (TUNA) as revolutionary tool able to correlate the electrical current map with the correspondent local morphology of CNF/resins. TUNA technique has proven to play a leading role in the identification of current paths and electrical interconnections, even without altering the morphology with usual treatments employed to create electrical contacts to the ground. Summing up, the good electrical performance together with the high mechanical properties due to a conductive cross-linked network of CNFs inside the resin demonstrate a charming applicative potential for the formulated nanocomposites as structural materials capable to provide a safe conductive path on the exterior skin, preventing serious damage to the aircraft.
