“…In the past, the entire ply was usually scanned by ultrasound or sectioned by tomography images of FEA regardless of the ply thickness. Due to the limitation of the technical accuracy, discontinuity or mutation occurred in the evolution of ablation area, which was shown in Figure 15 [ 6 , 35 ].…”

Coupled electrical–thermal finite element analysis (FEA) models are widely adopted to analyze the thermal ablation damage of carbon fiber reinforced polymer (CFRP) caused by lightning, but it is still difficult to analyze the ablation due to its complex space geometry. According to the principle of computerized tomography (CT), tomographic images of FEA models’ temperature fields with different thicknesses were obtained to calculate the mass loss and compare the damage morphology. The four areas including Area 0, Area I, Area II, and Area III; were separated from the temperature fields in terms of different vaporization and pyrolysis temperature ranges of carbon fiber (CF) and resin matrix. Ablation mass losses were calculated by pixel statistics and tomographic intervals, which were consistent with the experimental results. The maximum ablation area of unprotected CFRP was found on the tomography images of 50 μm rather than the surface by comparing tomographic images with different thickness due to the influence of the thermal radiation, but this effect was not found in CFRP protected by copper mesh. Some other phenomena, including continuous evolutions of ablation areas and the influence of the intersection angle on the direction of the ablation extension, were also discovered.

“…Various silver coated yarns were used with different amounts of coating and different fibre counts, as described in table 18. The results of the through-thickness conductivity tests are shown in table 19. It was found that the introduction of these conductive stitching fibres produced CFRPs with conductivities of up to 627 S m −1 , compared with only 5.0 S m −1 for the baseline composite.…”

“…CFRPs with thermoset matrices are generally brittle in nature and are susceptible to impact damage [1,2]. In addition to this, they have low off-axis electrical conductivity, herein referred to as conductivity, which can lead to joule heating and subsequent damage when current flows through the CFRP [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. This review discusses the research carried out to enhance the through-thickness electrical conductivity, with consideration of the effect on mechanical properties.…”

As the use of carbon fibre reinforced polymers (CFRP) is continuing to increase in engineering applications, more functionalities will be required. Having an enhanced through-thickness electrical conductivity can be a useful functionality for CFRPs which will minimise their damage from lightning strikes, and will help in their real-time monitoring. For most modification methods there is an adverse effect on the manufacturing and the fibre volume fraction, which influence the mechanical properties of the resulting composites. Simultaneous improvement of multiple properties of CFRPs is difficult, and as such the ways in which different materials and processes improve properties of CFRPs need to be understood in depth. This review discusses research that attempts to improve the through-thickness electrical conductivity of CFRPs with interest in the effects on mechanical properties, specifically interlaminar fracture toughness. The last section discusses the effect and use of these methods to improve structural health monitoring (SHM) of CFRP.

“…Further investigations quantitatively elucidate the mechanism of the lightning strike on the composite laminates, supported by the experimental lightning strike test and propose solutions for increasing electrical conductivity of such material systems. The effort on Life Cycle Assessment of the multifunctional composites, in order to prove the ecological improvements compared to the standard CFRP, will be continued [18][19][20][21][22][23][24][25][26][27].…”

Fiber reinforced polymers play a crucial role as enablers of lightweight and high performing structures to increase efficiency in aviation. However, the ever-increasing awareness for the environmental impacts has led to a growing interest in bio-based and recycled ‘eco-composites’ as substitutes for the conventional synthetic constituents. Recently, the international collaboration of Chinese and European partners in the ECO-COMPASS project provided an assessment of different eco-materials and technologies for their potential application in aircraft interior and secondary composite structures. This project summary reports the main findings of the ECO-COMPASS project and gives an outlook to the next steps necessary for introducing eco-composites as an alternative solution to fulfill the CLEAN SKY target.
