“…To date test standards representing the features of real world lightning events have been developed and are used to ensure that lightning protection systems can safely shield the underlying composite materials during the service life of an aircraft [8][9][10][11]. Variants of such test procedures have also been used to understand how the design parameters of a composite material and the parameters of the test arrangement influence the scale and form of material damage with and without protection systems [3][4][5][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. However, due to the experimental challenges associated with lightning strike testing (the high energy involved, the short duration of the event, the limited number of facilities and resulting cost and waiting time [26]) a body of computational research has also evolved which attempts to model the standard tests.…”

“…1 and 3). Both numerical and experimental studies of CFRP structures subjected to lightning strikes [12][13][14][15][16] proved that lightning still causes serious damage in such structures which extent dramatically increases when discharging occurs near metallic fasteners. In order to improve electrical conductivity of these materials various solutions of LSP of aircraft have been developed to-date.…”

The paper focuses on development of a multifunctional material which allows conducting of electrical current and simultaneously holds mechanical properties of a polymeric composite. Such material could be applied for exterior fuselage elements of an aircraft in order to minimize damage occurring during lightning strikes. The concept introduced in this paper is presented from the points of view of various scientific disciplines including materials science, chemistry, structural physics and mechanical engineering with a discussion on results achieved to-date and further plans of research.

“…Any variation of the electromagnetic (EM) properties can be revealed in the signals received. For composites, microwave testing methods have been developed for monitoring automated tape laying (ATL) processes (62) , detection of impact damage (63)(64)(65) , delamination (66)(67)(68) , air voids (69) , lightning strike damage (70,71) and moisture ingress in sandwich structures (72,73) . Compared with the other NDT methods, microwave testing has the advantages of being non-contact, no need for surface transducers, couplants or complicated signal post-processing, it is operator friendly, relatively inexpensive and has no ionising hazards (74)(75)(76)(77) .…”

Microwaves are a form of electromagnetic radiation commonly used for telecommunications, navigation and food processing. More recently microwave technologies have found applications in fibre-reinforced polymer composites, which are increasingly used in aircraft structures. Microwave energy can be applied with low power (up to milliwatts) for non-destructive testing and high power (up to kilowatts) for heating/curing purposes. The state-of-the-art applications at high power include curing, three-dimensional (3D) printing, joining and recycling, whereas low-power microwave techniques can provide quality checks, strain sensing and damage inspection. Low-power microwave testing has the advantage of being non-contact, there is no need for surface transducers or couplants, it is operator friendly and relatively inexpensive; high-power microwave energy can offer volumetric heating, reduced processing time and energy saving with no ionising hazards. In this paper the recent research progress is reviewed, identifying achievements and challenges. First, the critical electromagnetic properties of composites that are closely related to the heating and sensing performance are discussed. Then, representative case studies are presented. Finally, the trends are outlined, including intelligent/automated inspection and solid-state heating.
