Experimental Investigation Of Composite Materials And Validation Using Fea For Submarine Radome Design

Abstract

Radomes are electronic housings used for antennas operating both in maritime and airborne applications respectively. The purpose of radome is to transmit RF waves with minimal loss possible and to withstand under water severities at effective joint sealing and hydro static pressure. In order to withstand hydrostatic pressure up to 75 bar, these structures are made of composite materials possessing high RF transparency, high stiffness and corrosion resistance. The present work emphasizes on designing the shape, thickness, material identification, and Fabrication of laminates using hand layup by various materials and evaluating the mechanical properties by testing specimens as per ASTM standards. Furthermore, structural modeling and analyses of composites (using FEM), stress analysis for symmetrical orientation angles of laminae, buckling modes and failure criteria are investigated.
