Composite Pressure Vessels

The 16th European Conference of Fracture (ECF16) was held in Greece, July, 2006. It focused on all aspects of structural integrity with the objective of improving the safety and performance of engineering structures, components, systems and their associated materials. Emphasis was given to the failure of nanostructured materials and nanostructures including micro- and nano-electromechanical systems (MEMS and NEMS).

With his work, Martin Nebe provides principal insights into the mechanical response of composite pressure vessels subjected to internal pressure. By establishing and validating an in situ characterization methodology, the vessel’s geometry, its deformation behavior and the damage evolution process under internal pressure loading become accessible. This not only permits to trace back certain phenomena related to the manufacturing of these components but also allows to verify analytical and numerical modeling strategies. The exercised correlation of predicted and experimental results delivers detailed insights into design considerations to composite pressure vessels such as the definition of stacking sequence. The transfer of knowledge to a fullscale vessel geometry, which is representative for the use in fuel cell electric vehicles underlines the industrial application of this work. By combining numerical modeling, filament winding and experimental characterization, this work provides a sound foundation for future developments in the area of composite pressure vessels used for hydrogen storage.

Peak vessel efficiency generally occurred at the same wall thickness, implying the efficiency is mostly affected by the type of fibre/matrix combination selected. A slight improvement in efficiency was noticed by increasing the number of individual layers and allowing their thicknesses to vary. Finally, the manufacturing and testing aspects are described.

Pressure vessels are closed containers designed to hold gases or liquids at a pressure substantially different from the ambient pressure. They have a variety of applications in industry, including in oil refineries, nuclear reactors, vehicle airbrake reservoirs, and more. The pressure differential with such vessels is dangerous, and due to the risk of accident and fatality around their use, the design, manufacture, operation and inspection of pressure vessels is regulated by engineering authorities and guided by legal codes and standards. Pressure Vessel Design Manual is a solutions-focused guide to the many problems and technical challenges involved in the design of pressure vessels to match stringent standards and codes. It brings together otherwise scattered information and explanations into one easy-to-use resource to minimize research and take readers from problem to solution in the most direct manner possible. Covers almost all problems that a working pressure vessel designer can expect to face, with 50+ step-by-step design procedures including a wealth of equations, explanations and data Internationally recognized, widely referenced and trusted, with 20+ years of use in over 30 countries making it an accepted industry standard guide Now revised with up-to-date ASME, ASCE and API regulatory code information, and dual unit coverage for increased ease of international use
