摘要

The aim of this study is to propose methods for dome thickness distribution and the charge pressure of the liner for a 70 MPa type IV hydrogen storage vessel. The netting theory was employed to design the lay-up of the cylindrical section. For precise prediction of the dome thickness, a cubic spline function was utilized. Variable polar radii were used to reduce the fiber stacking and thickness accumulation near polar openings. To evaluate the designed lay-up, various failure criteria were applied so as to predict precisely the failure of composite layers in finite element analysis. In order to determine the most appropriate range of the internal pressure when filling hydrogen gas during filament winding process, the compressive pressure applied on the liner was calculated by taking into account the variety of winding tension, and the buckling and static analysis of the liner were carried out, respectively. The methods presented in this work provide a valuable reference for designing the type IV hydrogen storage vessels.
