Description
Summary:From the last decade aerospace industry, most device fabrication is based on the fly by wire technology. High-intensity radiated fields like lightning strikes cause electromagnetic interference when interacted with airplane surfaces. Electromagnetic interference influences various electronic devices to operate at the same frequency at which an unwanted source operates. Metals usually fill in as magnificent EMI shielding specialists. Yet, their substantial weight, significant expense, and defenselessness to structures of ecological debasement settle on them an undesired choice for some current electronic gadgets. Fiber-reinforced polymeric composite materials, on the other hand, are often lightweight. Unfortunately, fiber reinforced polymer composites are frequently incapable of carrying large electrical currents and electromagnetic forces safely. Lightning strike protection introduced to allow the currents and electromagnetic forces developed by the lightning strike to the other end of ground. The present work expounds on the suitability of metal matrix composite materials for EMI protection structures, explicitly for aviation applications. The reinforcement of AL 2 O 3 , SiC, and Fly Ash with AL6061composite improved the shielding effectiveness and mechanical properties at different percentages. Fabrication of material, measuring the electrical parameters and mechanical properties, interpreted based on experimentation. The fabricated composite produces shielding effectiveness of 93.48 dB, and it can be effectively used for aerospace applications. Graphical abstract
