Study on Burst Pressure of Type Ⅳ Hydrogen Storage Cylinder Based on Progressive Failure Analysis

Hydrogen has attracted worldwide attention due to its renewable and pollution-free advantages. Hydrogen fuel cell vehicles have become an important direction for the development of the automotive industry. Carbon fiber reinforced composite hydrogen storage cylinder with plastic liner (Type IV hydrogen storage cylinder) is the main research direction of vehicle hydrogen storage because of its lightweight and excellent resistance to fatigue and corrosion. However, its safety still receives much concern. In this paper, the burst pressure prediction model of type IV hydrogen storage cylinder was established by the user subroutine UMAT of finite element calculation software ABAQUS based on the Hashin failure criterion and the damage evolution law of carbon fiber composite. The damage evolution behavior of carbon fiber winding layer of the cylinder in the process of loading was analyzed. In addition, the influence of winding thickness, winding sequence and winding angle on the burst pressure was obtained.
