Abstract

The technology of high performance composites has evolved in industry only in the last twenty to thirty years. Since that composites have been used extensively in the aerospace industry. Pressure vessels made from fiber composite materials have had an enormous impact on engineering structures where weight savings is an important consideration. The high service pressure vessel must safely statically withstand without leakage or cracking the maximal operational pressure and fatigue load cycles resulting from recharging. The problems or issues in involved in the design and analysis of a filament wound composite pressure vessel is to optimize composite layer thickness and optimize fiber orientation configuration of composite laminate in order to have higher performance structures. This paper outlines analytical and finite element approaches were studies via both the first-ply failure strength on symmetrically laminated composite pressure vessel subjected to uniform internal pressure loads. Analyses were performed with different fiber orientation angles and various layer thicknesses to optimize the strengths of laminated pressure vessel. Different analytical methods together with most common failure criteria such as maximum stress and strain and the quadratic polynomial theories were used to predict the first-ply failure strengths of the laminated pressure vessel. Finite element analyses have been proved to be efficient and effective utilizing ANSYS 7.1 inc software in the analytical prediction of first-ply failure strength of laminated composite pressure vessels. The pressure vessel was designed with a T6 Aluminum 6061 cylinder with elliptical end closures acts as the liner which was over-wrapped with HM Graphite/Epoxy Composite. The accuracy of the theoretical and numerical prediction of first ply failure pressure was verified by a verification study ad literature test data.
