In today’s fast – paced world of electronic information technology, electromagnetic radiation has emerged as a critical threat to both electronic equipment safety and human well – being. As a key defense against electromagnetic interference, carbon fiber materials’ shielding capabilities depend not only on their structure but also on their inherent electromagnetic properties. Traditional shielding materials like silver and copper, despite their excellent conductivity, fall short in aviation, aerospace, and marine environments where corrosion resistance and light weight are also essential. Carbon fiber materials, with their high corrosion resistance, low density, and temperature tolerance, are ideal for electromagnetic shielding. They serve as the primary barrier against electromagnetic pulse interference, safeguarding in – cabin electronic equipment and cables, and thus have garnered significant academic interest.
Carbon fiber materials, known for their mechanical strength and electromagnetic characteristics, are widely used in drones, covering over 60% of a typical drone’s body. Presently, their main role is to replace metals and reduce drone weight, with less emphasis on shielding effectiveness. However, as strong electromagnetic pulse technology advances and becomes more prevalent, drones face increasingly complex electromagnetic environments and growing threats. Consequently, drone skins need not only to lighten the aircraft but also to provide electromagnetic shielding.
Experts have delved into the shielding effectiveness of carbon fiber materials under strong electromagnetic pulses. They’ve explored ways to measure electromagnetic shielding performance by enhancing and testing the conductivity of carbon fiber materials based on their composition. They’ve also analyzed how the number of plies and wire thickness of carbon fiber materials affect shielding effectiveness. Using Fourier transform principles, they’ve introduced shielding effectiveness testing methods and procedures. Furthermore, they’ve examined the application of carbon fiber materials in cable protection and, via simulation, studied how transmission line length impacts terminal shielding effectiveness under strong electromagnetic pulses. Results indicate that carbon fiber materials offer robust shielding against strong electromagnetic pulses and have great potential in aerospace due to their light weight and corrosion resistance.
