A multi-section tubular member including a sleeve surrounding and bridging a joint between a first section and a second section of the tubular member, and a method of forming a multi-section tubular member are disclosed. A polymeric sleeve may extend over a portion of the first section and an adjoining portion of the second section. A length of heat shrink tubing may be placed over the sleeve and heated, thereby compressing the heat shrink tubing around the sleeve. The sleeve may then be thermally bonded to each of the first section and the second section. The heat shrink tubing may then be removed, leaving the sleeve securely joining the first section and the second section to form a multi-section tubular member.

A segment and a method for producing such a segment, in particular for an aircraft, having a skin field and a skin field stiffening structure. The skin field and stiffening structure are made from fiber-reinforced plastic materials. The stiffening structure is bonded to an inner surface of the skin field and comprises a multiplicity of first stiffeners and mounts which are formed integrally with the first stiffeners and extend in a transverse direction of the first stiffeners for the connection of second stiffeners to form an integral lattice structure. Reinforcement elements are provided for mechanically fixing the mounts to the skin field. Each reinforcement element has a connection section and a blocking section having an extension in a direction inclined to the connection section. The connection section penetrates the skin field and the mounts, and the blocking section is in contact with an outer surface of the skin field.
