Linear Elastic behaviors of composite navigational buoy shells are studied using Finite Element software SolidWorks Simulation. In the present work, a composite navigational buoy with different fiber angle/orientation, i.e., 0°, 15°, 30°, 45°, 60°, 75°, and 90°, are analyzed using three composite materials: Polyester/E-glass, Vinyl ester/E-glass, Epoxy/E-glass through comparative analysis. The effect of the ply angle on composite cylindrical shells subjected to hydrostatic pressure is investigated. Both stress and deflection are considered in the study. The results show that Epoxy/E-glass with ply angle 0° has the highest Tsai-Wu factor of safety 4.23. © 2020 The Authors. Published by ELSEVIER B.V.

Introduction Marker buoys and navigation buoys have long been familiar sights in port and waterways, and along seashores. Conventional navigational buoys are made of steel materials, they are heavy, susceptible to corrosion and erosion,
