Analysis of Shielding Effectiveness for Square Mesh Wire with Metal Matrix Composite of Al6061 with Fly-Ash

Abstract

One of the significant problems facing aerospace applications over the past two to three decades was fuel consumption. The aircraft industry prefers composite materials (Fiber Reinforced Plastic) to resolve this issue. These composite materials have less weight and good mechanical properties. The major drawback with these fiber-reinforced materials was the inability to conduct the high electrical fields and electrical currents, which cause damage to the aircraft's structure when lightning strikes occurred. The designer should consider a lightning strike protection (LSP) system that allows current and field lines to pass freely through the surface while providing EMI shielding for the aircraft. The best method for allowing the current and field through the aircraft surface by the mesh structure. The mesh structure is examined in this study to offset the decreases in density and fuel consumption. This mesh structure was made using the AL6061 metal matrix material. AL6061 metal matrix composite electrical properties were taken into considerationdepending up on the reinforcement or strengthening of fly ash particulates at different percentages at X-band. The composites shielding effectiveness is gradually increased to 6 dB.
