Design of Type-IV Composite Pressure Vessel Based on Comparative Analysis of Numerical Methods for Modeling Type-III Vessels

Abstract

Compressed gas storage of hydrogen has emerged as the preferred choice for fuel cell vehicle manufacturers, as well as for various applications, like road transport and aviation. However, designers face increasing challenges in designing safe and efficient composite overwrapped pressure vessels (COPVs) for hydrogen storage. One challenge lies in the development of precise software programs that consider a multitude of factors associated with the filament winding process. These factors include layer thickness, stacking sequence, and the development of particularly robust models for the dome region. Another challenge is the formulation of predictive behavior and failure models to ensure that COPVs have optimal structural integrity. The present study offers an exploration of numerical methods used in modeling COPVs, aiming to enhance our understanding of their performance characteristics. The methods examined include finite element analysis in Abaqus, involving conventional shell element, continuum shell element, three-dimensional solid element, and homogenization techniques for multilayered composite pressure vessels. Through rigorous comparisons with type-III pressure vessels from the literature, the research highlights the most suitable choice for simulating COPVs and their practicality. Finally, we propose a new design for type-IV hydrogen composite pressure vessels using one explored method, paving the way for future developments in this critical field.

On the Multidisciplinary Design of a Hybrid Rocket Launcher with a Composite Overwrapped Pressure Vessel

“…COPV modelling requires appropriate consideration of the geometrical features of the configuration. Different works can be found in the literature dealing with winding process modelling and thickness profile prediction [22][23][24][25][26], which are crucial to generate a high-fidelity geometric model of COPV with the appropriate path profiles.…”

Lightweight Type-IV Hydrogen Storage Vessel Boss Based on Optimal Sealing Structure

“…The volume of the Type IV hydrogen storage vessel is 150 L. The boss is made of AL_6061, the inner liner is made of high polymer HDPE, and the reinforcement layer is made of T800s carbon fiber and phenolic resin composite with 60% fiber content. The layering winding method is a mixture of helical and hoop winding [35]. The helical winding angle is 12.72 • , the total thickness of the helical winding is 8.47 mm, and the total thickness of the annular winding is 9.47 mm.…”

Analysis of the Boss Structure of Type Ⅳ Composite Vessel for a High-Pressure Hydrogen Tube Trailer

“…For years, analytical solutions and numerical analysis in finite element analysis (FEA) [23] were used to investigate the effects of different boss structures. Bouhala et al [24] delve into the numerical methods, encompassing conventional shell elements, continuum shell elements, three-dimensional solid elements, and specialized homogenization techniques for multilayered composite pressure vessels. The findings suggest that threedimensional solid elements provide the highest level of accuracy in modeling composite pressure vessels.…”
