Abstract : A study has been made of the application of fibre reinforced composite materials to the construction of a lightweight, long life, high pressure, gas storage vessel for satellite attitude control systems. The operational requirements demand good dynamic fatigue, long term pressure holding capability with negligible leakage and compatibility with a wide range of media. These requirements can be met by the use of composite materials manufactured from the recently introduced carbon and PRD.49 fibres which, unlike glass fibre composites, have a stiffness comparable with metal materials. In addition, these materials have excellent specific tensile strength and good resistance to ageing and fatigue, such that vessels can be constructed with a 'long term' performance rating, much higher than that available from metallic structures. This document reports on the results of tensile static, dynamic fatigue and very long term static fatigue strength tests with type 2 carbon fibre composite structure NOL rings.
