Aluminium Lined, Carbon Composite Overwrapped Pressure Vessel

Abstract

A numerical analysis of filament-reinforced internally pressurized cylindrical vessel with over-wrapped metallic liner is presented, the study deals with simulation of aluminium liner pressure vessel overwrapping by composite T800/epoxy was selected, ABAQUS Software was use in which 20 layers of composite were analysed. The stress state of the pressure vessel under the internal pressure of 33MPa was analysed, and the bursting strength was predicted to be 92.3MPa. MATLAB software was used to simulate the winding process, the 5 axis numerical control winding machine was used for the actual winding, and the fibres were arranged in a regular and uniform way, and the sliding phenomenon was not occurred. After solidifying, the bursting strength was 85.4MPa, and the difference between the actual value and the predicted value was 6.9%. The experimental results were in good agreement with the simulation results.
