Description

This paper investigates innovative reinforcement strategies for hydrogen storage tanks, introducing a novel method that utilizes carbon fiber strips arranged in both radial and axial directions. The approach focuses on reinforcing the tank’s dome with strategically placed carbon fiber strips distributed axially and circumferentially. To evaluate the effectiveness of this reinforcement, finite element analysis is performed, incorporating the Hashin’s failure criteria to predict potential failure modes in the structure. The simulation results are validated against experimental benchmarks from the literature. The findings indicate that optimally sized carbon fiber strips reduce equivalent stress around the dome by 29% for axial stress and 46% for hoop stress, with only a 6.5% increase in weight.
