Investigation of Electromagnetic Shielding for Wire Mesh Composite for Aircraft against Lightning Strike

Abstract

Nowadays, fly-wire is only used for flying-related things. All plane controls depend on electronics, but they also must deal with high-intensity radiated fields. This equipment might need an electromagnetic shield to protect it from outside electromagnetic pollution. The current work aims to develop a mesh around the operating equipment to protect and make it work better. AL6061 was used to create a shield with a metal matrix composite. Here three combinations of Metal Matrix Composite (MMCs) were considered to protect from the high-intensity radiated fields. These MMCs are AL6061+10%Al_2 O_3+5% FA (MMC-1), AL6061+15% Al_2 O_3+5% FA (MMC-2), and AL6061+20% Al_2 O_3+5% FA (MMC-3) made the process of shielding more effective at different percentages. Explements are Measures that take the electrical characteristics, and they are by Shielding Effectiveness (SE) of different concentrations of fly ash and Al_2 O_3.SE of 50 dB is achieved; hence these MMCs can be used in aircraft and other applications as a shield.
