Optimal design of the type III hydrogen storage tank
for different carbon/epoxy materials by modified
differential evolution method
In this study, the main objective is to minimize the failure index of a cylindrical
laminated composite hydrogen storage tank under internal pressure. The first
step is to obtain the distribution of stress components based on Classical
Laminated Plate Theory (CLPT). The second is to evaluate the burst pressure of
the tank according to three different first ply failure criteria and then to
compare the results with the experimental and numerical ones from literature.
In the final part of the study, the best possible combination of winding angles,
stacking sequences and thicknesses of laminates satisfying minimum possible
stress concentration will be obtained for different Carbon/Epoxy materials by
Differential Evolution Method. The stress components and, the burst pressures
reached according to Hashin-Rotem, Maximum Stress, and Tsai-Wu first-ply
failure criteria, have been complied with experimental and numerical results in
the literature for Type III pressure vessels. Manufacturable Type-III tank
designs have been proposed satisfying the 35 MPa burst pressure for different
Carbon/Epoxy materials.
