Abstract: Type IV hydrogen storage vessels have become one of the most promising vehicle energy storage equipment, while during the rapid filling process and service life, the hydrogen storage vessel suffers the significant temperature rise effects or environmental temperature change. To improve the safety and reliability of type IV hydrogen storage vessels, it is of great significance to investigate the burst failure behavior under such operating conditions. In this work, the steady-state heat transfer model, micromechanics model, and thermal-mechanical coupling model were established based on the micromechanics of failure theory. And a multiscale burst failure analytical method was developed to study the influence of temperature at the range of 25℃ to 85℃ on burst failure behavior. The results show that, fiber damage is the main cause of the burst failure of the type IV hydrogen storage vessel, and the predicted burst pressure and failure location agree with the experimental result well. As the temperature rises, thermal compressive stress generated by non-uniform temperature distribution and thermal expansion, partially offsets the tensile stress generated by the pressure, and slows down the development of the constituent damage. And the strength of the composite winding layer decreases, leading to a decrease in the burst pressure of the vessel. When the temperature of the outer or inner wall surface rises from room temperature to 85℃, the pressure of the initial fiber damage decreases by 27.5% and 12.1%, and the burst pressure decreases by 12.5% and 4.6%, respectively.
