An Investigation of Different Composite on Performance of Pressure Vessel by Filament Winding

Abstract

Lightweight composite pressure vessels are very important in many applications such as aerospace, constructions, automotive , energy gas and liquid saving systems due to their high strength and stiffness weight ratios replacing metal alloys in alternative applications. In the present paper, different fibers are used to reinforce epoxy matrix (carbon fiber, Kevlar fiber and E- glass fiber) to fabricate composite pressure vessels with different winding angles orientations [±45°3], [±55°3], [±65°3] and [±75°3] to investigate different mechanical performances like burst pressure and hoop stress. The von-Mises stress of the composites pressure vessel is performed by building a model based on FEM- ACP workbench 17.The obtained results show a strong influence of type of reinforcing fibers and winding orientations on the vessel strength where the maximum pressure recorded up to 100 bar for carbon fiber reinforced laminates which show no failure. While the rest composite laminates exhibit failure. As well as the internal pressure and hoop stress performance show the best results are for composite laminates with [±55°3] angle orientation. The von-Mises stress studies show that best performance is for [±65°3] winding angle observed at Kevlar fiber composite laminate is 4924.8 MPa while the lowest stress value observed with glass fiber composite laminate with [±75°3] winding angle is 606.02 MPa.
