Electromagnetic Interference Shielding via Graphene Incorporation in Glass Fibre Reinforced Polymer Composites

Abstract

The primary objective of the research was to investigate the Shielding Effectiveness (SE) of laminates composed of Glass Fibre Reinforced Polymer Composites (GFRP) by incorporating different quantities of graphene.Employing ANSYS HFSS, the setup was simulated to extract loss signal parameters, which are instrumental in calculating SE for the samples. Through the hand layup technique, GFRP is fabricated with varied graphene additions and glass fibre sequences such as 0°/90° and 45°/90°. The shielded box method enabled them to experimentally derive scattering parameters S11 and S21. The result shows that increased graphene content correlates with an augmented laminate surface area, leading to heightened material SE. Analytically, introducing graphene at levels ranging from 0 to 5% yields a increases improvement in in SE, translating to a 16% improvement. Experimentally, the SE displays a remarkable increase 24.97 % enhancement.
