Lightweight multilayer composite structure for hydrogen storage tank

Composite pressure vessel has been applied by NASA for the first time. Safe low-cost efficient composite hydrogen-storing device is a key technique affecting the generalization and application of hydrogen energy. By combining the shear theory and based on the highly heave-stable shear behavior shell structure lightweight design, this paper describes researches on the lightweight design of pressure vessel lining and, on the basis of completing the numerical analysis of hydrogen storage tank, extracts its stress isogram, achieving the conformity or tangency of fiber weaving type with stress load isoline and accomplishing lightweight design of the tank and reduced production cost. The method herein can be further generalized to the storage of hydrogen energy and pipe component design.
