An end-cap arrangement for a polymer pressure vessel comprises an end-cap, a filler element for being provided in the vicinity of the end part of the polymer pressure vessel, and a polymer outer ring. The end-cap comprises a polymer end-cap part and a polymer inner ring part being integrally connected to the polymer end cap part. The end-cap is provided for inserting into an end part of the polymer pressure vessel such that the polymer end-cap part seals the end part of the polymer pressure vessel. The polymer inner ring part and the polymer outer ring are arranged for providing radial compression of the filler element.

A method for manufacturing a composite part with continuous fiber reinforcement and a polymer matrix from a composite preform. On one of the faces of the composite preform, a demarcated layer of thermoplastic polymer is deposited using an additive manufacturing method.

A stimulation lead can include segmented electrodes arranged in a single or double helix or other helical arrangement. In one method of manufacture, an electrode carrier with segmented electrode receiving openings is used. Another method employs a connected framework of helically arranged pre-electrodes that are separated during manufacture. Yet another method employs a mold to generate a planar carrier over the segmented electrodes followed by rolling the carrier into a cylinder. A further method includes forming an electrode assembly by alternative segmented electrodes with non-conducting spacers.

A structural assembly includes a first member defining a matrix material, and a second member defining a skin. The skin has a roughed surface of hooks or barbs. The second member is engaged to the first member to define a mechanically interlocked assembly. The assembly may include an open-cell matrix material in a glue-less connection. The assembly may include a chemical bond in addition to a mechanical bond. The assembly may include internal layers of pre-impregnated composite fiber and resin. The skin member may act as a jig for a green composite member. The skin member may be deformed in a press to present a non-planar surface for such other members as may be attached to it. Assemblies may be formed with mechanical interconnection in place of glue or adhesive connections. Assemblies may be formed to may light, thin-walled pipe, flasks, pressure vessels and so forth.
