Abstract

Burst pressure is the vital parameter to be strong-minded for their design. Burst pressure is the pressure at which vessel crack and core fluid seep outs. A design shelterbound that ought to not be surpassed. Further than this pressure possibly willescort to mechanical fall foul of and enduring loss of pressure restraint. The present work is aimed in studying the pressure vessel (PV) made with composite material. During the study the PV is fabricated by glass fiber with 90O fiber angle and performed hydrostatic test. Later the same PV is modeled in Ansys and analyzed with various fiber angles to determine the failure by considering their deformation, stress and strain of the PV using GFRP, CFRP and hybrid composites. At last the results obtained are validated.

Highlights

  • A pressure vessel playsa very important role as they are used to store many liquids under high pressure

  • Some of the pressure vessels has to carry high pressures, and thickness of the vessel walls must increase in order to provide adequate strength

  • Composite pressure vessel made with glass fiber is fabricated with dimension as mentioned above in table 1, and tested

Summary

INTRODUCTION

A pressure vessel playsa very important role as they are used to store many liquids under high pressure. Some of the pressure vessels has to carry high pressures, and thickness of the vessel walls must increase in order to provide adequate strength. It is a design safety limit that should not be exceeded Exceeding this pressure may lead to mechanical breach and permanent loss of pressure containment. Many studies and research works were carried out by various researchers for the better understanding of structural performance of laminated composite pressure vessels. Cylindrical shells such as thin walled laminated composite unstiffened vessels like deep submarine exploration housings and autonomous underwater vehicles are subjected to any combination of in plane, Out of plane and shear loads due to the high external hydrostatic pressure during their application. Due to the geometry of these structures, buckling is one of the most important failure criteria
