Modern composites, using continuous fibres in a resin matrix, are important candidate materials in the engineering of energy-efficient structures. In many applications, fibre/matrix materials are lighter, stronger and more cost effective when compared with traditional materials like metals. Filament-wound tubular structures, more specifically pressure vessels, offer significant weight saving over conventional all metallic ones for containment of high pressure gases and liquids. The main advantage of COPV’s over similar sized monolithic metallic pressure vessels is a much better strength-to-density ratio due to significant mass reductions.Currently, a large amount of research works has been concentrated on the stress and failure analysis of the cylindrical part of the composite-metallic vessels. The study of the stress and strain distribution in the structure is of prime interest for designing the vessel. The complicated failure mechanisms and degradation mechanisms are distinct characteristic of composites although they exhibit high stiffness- and strength-density ratios. In this paper various failure modes of composite pressure vessels are studied such as failure due to hygrothermal stresses, influence of flaws, effect of thermal loads etc.
