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.
