A Design Assessment for Metallic Pressure Vessels Circumferentially Reinforced with a Pre-Tensioned High-Specific-Strength Anisotropic Composite Overwind

Abstract

A design assessment is presented for thick-walled metallic pressure vessels circumferentially reinforced with a pre-tensioned high-specific-strength anisotropic fibre reinforced composite overwind. The assessment is restricted to the most important study of evaluating, for five potential composite overwinds, the relationship between the reinforcement thickness and metallic liner thickness to yield a vessel of comparable strength to an all-metal reference vessel. The resulting data are nevertheless used in a series of ancillary analyses, namely weight comparisons, strain to failure studies and detailed stress computations, to establish optimum configurations and, moreover, to identify the most suitable overwinding material. The influence of variations in the considerably lower transverse moduli (radial and axial) of the circumferentially reinforcing material is also considered by repeating the assessment studies for both 10GPa and IGPa transverse moduli composite overwinds.
