Optimization of the Winding Layer Structure of High-Pressure Composite Overwrapped Pressure Vessels

The large thickness COPV is designed by netting theory and the finite element simulation method, but the actual performance is low and the cylinder performance still cannot be improved after increasing the thickness of the composite winding layer. This paper analyzes the reasons for this and puts forward a feasible solution: without changing the thickness of the winding layer, the performance of COPV can be effectively increased by increasing the proportion of annular winding fiber. This method has been verified by tests and is supported by theory.

This paper analyzes the issue of low performance in the large thickness composite overwrapped pressure vessel (COPV) designed using netting theory and the finite element simulation method. It proposes a feasible solution that increases the proportion of annular winding fiber to improve the performance of COPV without changing the thickness of the winding layer. This method has been verified through tests and is supported by theory.
