Abstract
A strut comprises a composite cylinder with a mid-strut fitting mounted on an interface region on a mid-portion of said cylinder. At least in the interface region, layers of helical-filaments are displaced radially-outward and even inclined with respect to an axis of the cylinder such that they may follow a path with a radial component. A mid-strut fitting is provided which has a plurality of teeth on an inner circumferential surface. The plurality of teeth engage the helical-filaments in the interface region to provide a mechanical connection. Portions of surface and intermediate layers of the helical-filaments may be removed to expose ends of those filaments in the interface region before mounting the mid-strut fitting on the cylinder.
