Examination of Shielding Effectiveness on Al6061 Composite Material Reinforced with Fly Ash for Oblique Incidence

Abstract

Over last two decades a high extent of concentration is on reducing the weight of the commercial aircraft with enough mechanical properties like strength, stress etc. Composite materials are preferable for construction aircrafts with less weight and good mechanical properties. But these composite materials have very less conductivity, suppose if the lightning strikes the aircraft flow of current through exit terminals of it was not possible, so there is a possibility for physical damage of the aircraft. To overcome the lightning effect on aircraft lightning strike protection (LSP) should be involved, for that in the present work AL6061 composite was considered for the construction of aircraft. To improve the shielding and mechanical properties of the material, fly ash particles are reinforced at different percentages. Electromagnetic shielding and mechanical properties are measured for the above material at X band. MATLAB Simulation results are compared with the conventional AL6061 composites for arbitrary case.
