Abstract
A composite shaft with an end fitting mounted on one end of said shaft and a preload structure arranged to provide a biasing force to bias the composite shaft against the end fitting. The end fitting has a first interface surface, the first interface surface being tapered at an angle to the shaft axis and the shaft has a second interface surface for engagement with the first interface surface and is tapered at an angle to the shaft axis, the second interface surface extending axially from a first end to a second end, the shaft being thicker at the second end than at the first end. The shaft has a third interface surface and the preload structure has a fourth interface surface and the contact pressure of the third interface against the fourth interface increases from the first end of the shaft to the second end of the shaft.
