Design of Laminated Pressure Vessel

Pressure vessels are closed container contains gasses or liquid under internal pressure. Isotropic materials like metals are used for realizing hardware, the material is not fully utilized in longitudinal/ meridional direction resulting in over weight components. Instead of Isotropic metals, fiber reinforced epoxy composites are used for Pressure Vessels because they offer higher specific strength and moduli and tailoribility characteristics will result in reduction of weight of the structure. The determination of a proper winding angle and thickness is very important to decrease manufacturing difficulties and to increase structural efficiency. In this study, material characterization of FRP of carbon T300/Epoxy for various configurations as per ASTM standards is determined. The design of Laminated Pressure Vessel is described in detail. Netting analysis is used for the calculation of hoop and helical thickness of the Pressure Vessel. A balanced symmetric ply sequence for carbon T300/epoxy is considered for entire Pressure Vessel. Progressive failure analysis of composite Pressure Vessel with geodesic end dome is carried out. The results can be utilized to understand structural characteristics of filament wound Pressure vessels.
