Abstract
The present invention envisions a concentric structural combination of elements, consisting of an elongate core component, which is terminated at each end on the internal surface of a chambered coupling, and a elongate sheath component which consists of an interlaced configuration of assemblies of non-metallic filamentary elements embedded in a polymer matrix, the sheath component being bonded at each end to the external surface of the coupling, the load-elongation characteristics of the core and sheath components being chosen so as to ensure that both components share substantially in the load-bearing under the working load conditions, with at least 50% of the load being borne by the aggregate of the non-metallic elements, and the sheath and matrix being disposed so as to substantially cover and protect the core and coupling components.
