Abstract: A tubular structure is described herein comprising an elongate tubular member extending between a first end and a second end, wherein the tubular member comprises an inwardly tapered portion adjacent said first end, the inwardly tapered portion narrowing the tubular member in a longitudinal direction towards said first end. A nut is also provided internally of said tubular member at said inwardly tapered portion, said nut having an outer surface that is in contact an inner surface of said tubular member. An annular member is also provided externally of said tubular member at said inwardly tapered portion, said annular member having an inner surface that is in contact with said outer surface of said tapered portion. The inner surface of said tubular member at said inwardly tapered portion is tapered so as to extend at an angle that compliments an angle of the outer surface of said nut.

Abstract: 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.

Abstract: A composite tubular structure includes an elongate composite member having an inwardly tapered section at an end and an embedded nut retained in the end inwardly tapered section for forming a connection with another component. The inwardly tapered section has an inner surface which follows a tapered outer surface of the embedded nut, the inwardly tapered section narrowing the composite member in a longitudinal direction towards the end so as to provide a constriction which retains the embedded nut within the inwardly tapered section. The embedded nut comprises a multipart nut, comprising an internal nut and an internal support member, and wherein the internal nut is arranged to slide within the internal support member in a direction away from the end of, and into, the elongate composite member when the composite tubular structure is under conditions of excessive axial compressive load.

Abstract: A composite tapered tubular assembly includes a composite tapered tube extending between a first end and a second end and tapered so as to have a smaller radius R1 at the first end than a radius R2 at the second end. The assembly also includes a first internal annular wedge that is in contact with an inner surface of the tube at said first end and a first external annular wedge in contact with the outer surface of the tube at said first end. The assembly further includes a first nut provided at said first end that is configured to be connected to said first internal wedge and a second external annular wedge provided on an outer surface of the tube and a second internal annular wedge in contact with the inner surface of said composite tube at said second end, and a second nut connected to an internal surface.
