    摘要： A composite shaft with an end fitting mounted on an interface region on at least one end of said shaft, and a preload structure arranged to provide a biasing force to bias the composite shaft against the end fitting; wherein the preload structure is in an interference fit with the composite shaft. The preload structure is applied to the composite shaft in a subsequent operation to the mounting of the end fitting to the shaft.

    摘要： 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.

    摘要： A housing for an electrical device such as a battery includes a casing with opposing ends. The casing is made of a composite material such that the housed device is surrounded by composite walls containing intumescent material which protects the outer composite materials from high temperatures generated inside the housing. An end cap is provided having a sandwich structure with a core, configured to evenly distribute compressive pre-load across a battery stack in the housing. A height adjustable end cap is also provided.
