“…The nickel is heated and even melted due to the Joule heating effect, which consumes a large amount of the lightning current energy. The lightning current energy is further consumed by the conductive CFWF 43 . In other words, the outer layer of nickel together with the CFWF forms a rapid conductive path, which effectively improves the dispersion of LS current and the attenuation of energy.…”

In this study, a dual conductive network of nickel-coated carbon fiber woven fabrics (Ni-CFWF) was presented for indirect and direct lightning strike protection (LSP) of carbon fiber reinforced polymer (CFRP) composites. The Ni-CFWF prepared by electroless plating was bonded to the top surface of a CFRP composite. Excellent electromagnetic interference shielding effectiveness of Ni-CFWF/CFRP composite was achieved with a value of 92.87 dB in the frequency range 8.2-12.4 GHz, 189.22% greater than that of the pristine CFRP composite. Moreover, the prepared Ni-CFWF also exhibited a good direct lightning strike (LS) protection performance. The maximum LS damage depth and area of the Ni-CFWF/CFRP composites were reduced by 21.59% and 6.11% under a simulated lightning current with the peak of 100 kA, respectively. Correspondingly, the residual strength of the Ni-CFWF/CFRP composites was maintained at 92.65% after LS, demonstrated the LSP effectiveness. Our work provides an effective strategy for the design of a protective system that considers both indirect and direct LSP.

Carbon nanotube (CNT) films are well known for their ultra-low density, high porosity, tunable conductivity and a number of other desirable characteristics. Integrating CNT films into composite materials would endow these structural materials with multifunctionality while adding only negligibly to their weight. This review introduces the fabrication of CNT films and presents the state-of-the-art research advances of CNT-film-enabled functions of composite materials, such as resistive heating, lightning strike protection, electromagnetic interference shielding, and structural health monitoring. Future research on CNT-film-based multifunctional composite materials is also discussed.

“…Composite materials negatively impact LSP instead of conductive metals. According to Chu et al (2019), CFRP composites have been widely employed in aviation parts for several applications because of their exceptional strength and stiffness, making them an excellent choice when weight, strength, and resistance to erosion are critical factors to consider. Gulzar et al (2020) worked on improving the electromagnetic SE of composite materials.…”

Since composite materials were initially used in airplanes a few decades ago, substantial research has been done on problems such as lightning strike protection (LSP) and electromagnetic interference (EMI) shielding. In the current state of technology, the aerospace industry needs cutting-edge materials to meet requirements like lower weight and higher values of strength and stiffness and protect against electromagnetic interference. On the other hand, the metallic mesh performs poorly at high frequencies (UHF and SHF). Many present and future equipment on airplanes can only operate in the frequency range referred to above. Metal wire mesh matrix composite (MWMMC) materials may be employed to shield airplanes against electromagnetic interference (EMI) as a result of this research. In this work, we made three different MWMMCs represented as MMC-1 with 95% AL6061+5% Fly ash, MMC-2 with 90% AL6061+10% Fly ash, and MMC-3 with 85% AL6061+15% Fly ash. In this article, a stir-casting method was used to try to make Al6061 metal matrix composites that were made stronger with different amounts of fly ash particles. With fly ash, the AL6061 metal matrix composite protects against lightning strikes. So that it may serve as an aircraft surface MWMMC. The material's thickness should be maintained as low as possible. It decided to explore oblique incidence with a different mix of fly ash, reinforced to pure AL6061, to provide more significant shielding to better approximate the signal toward the practical case. Compared to the plane sheet, the shielding effectiveness of the materials and the weight of the material will be reduced. In other words, the maximum shielding effectiveness obtained was 37dB and 20 dB. The shielding effectiveness of 40.5 dB of the manufactured composite is obtained, and it is beneficial for aerospace applications.
