AbstractIn the 21st century, most of the energy demand is covered from fossil fuels. However, fossil fuels cause high emissions of greenhouse gases and resources of the fossil fuels reduce day by day. Due to these disadvantages, researchers focused on to finding alternative and renewable energy sources. At this point, hydrogen has become an important energy source and many researchers have developed design and optimization procedure of composite hydrogen storage vessel in various fields uch as gas plants, power plants, aerospace, chemical and automotive industry. In the present study, the main purpose is to see effect of the different carbon/epoxy material type on optimum stacking sequences design of Type III pressure vessel. The first step is to gain the distribution of stress components based on Classical Lamination Theory (CLT). The second step is to determine the burst pressure of the Type III pressure vessel by using Tsai-Wu failure criteria and then to compare the result with analytical, experimental and numerical ones from literature. In the final part of the study, for different carbon/epoxy materials, the best possible combination of winding, stacking sequences and thicknesses of laminates satisfying minimum possible stress concentration have been obtained by Differential Evolution (DE) stochastic optimization method.
