Abstract
A composite filament-wound shaft with an end fitting mounted on an interface region on at least one end of said shaft, wherein in said interface region filaments of the filament-wound shaft are angled with respect to the shaft axis such that they follow a path with a radial component and have been cut so as to expose the ends of said filaments in said interface region; and wherein said end fitting comprises a helical thread engaging with said interface region. The helical threaded engagement provides excellent load transmission of axial forces and is therefore well suited to tension and compression elements. The joint provides a low cost and low weight interface.
