ABSTRACT
Use of polymer composites in manufacturing hydrogen storage tanks, allows
minimizing the weight, improving the aesthetic and also increasing the pressure
vessel mechanical, impact and corrosion behavior. In this paper, cylindrical
composite pressure vessels constituting of metallic internal liner and filament wound
composite material as the outer shell were investigated. The Finite Element Method
is used to predict the mechanical behavior of pressure vessels. The influence of
metallic and composite layers thicknesses, number of composite layers and winding
angle of filament-wound composite on the designed tank were investigated. A
parametric study was performed to find out the optimal tank design.
