The first carbon composite layer may include one or more carbon-fiber-reinforced thermoplastic prepreg plies.

A stretchable conductor includes a substrate with a first major surface, wherein the substrate is an elastomeric material. An elongate wire is on the first major surface of the substrate; the wire includes a first end and a second end, and further includes at least one arcuate region between the first end and the second end. At least one portion of the arcuate region of the wire in the region has a first surface area portion embedded in the surface of the substrate and a second surface area portion unembedded on the substrate and exposed in an amount sufficient to render at least an area of the substrate in the region electrically conductive. The unembedded second surface portion of the arcuate region may lie above or below a plane of the substrate. Composite articles including a stretchable conductor in durable electrical contact with a conductive fabric are also disclosed.

A system is disclosed for additively manufacturing a structure. The system may include a feeder configured to feed a thin-film material through the system, and a cutter configured to cut out of the thin-film material a pattern associated with a shape of the structure at a particular layer within the structure. The system may also include a placer configured to place the pattern in at least one of a desired location and a desired orientation.

A composite structure comprises stacked sets of laminated fiber reinforced resin plies and metal sheets. Edges of the resin plies and metal sheets are interleaved to form a composite-to-metal joint connecting the resin plies with the metal sheets.

A method for manufacturing a laminated iron core includes preheating a laminated body in which a plurality of iron core pieces are laminated and which includes a resin filling hole, measuring a temperature of the laminated body after preheating the laminated body, determining whether or not the temperature measured is within a predetermined range, feeding the laminated body into a molding device in a case where it is determined that the temperature is within the predetermined range, and filling the resin filling hole of the laminated body with a resin material in the molding device.

Disclosed herein are composite shafts for sporting goods, such as archery arrows, golf clubs, and rifles, which include a reinforcing layer to improve the performance of the sporting goods.

A method for manufacturing a structural component of a blade segment for a rotor blade includes providing a mold of the structural component having an outer wall that defines an outer surface of the structural component. The method also includes laying up one or more fiber layers in the mold so as to at least partially cover the outer wall. As such, the fiber layer(s) form the outer surface of the structural component. Further, the method includes providing one or more metal mesh layers having one or more ends. Moreover, the method includes providing a cover material to the end(s) of the metal mesh layer(s). In addition, the method includes placing the metal mesh layer(s) with the covered end(s) atop the fiber layer(s). Thus, the method includes infusing the fiber layer(s) and the metal mesh layer(s) together via a resin material so as to form the structural component.

A material system may include: an aluminum layer; a glass composite layer adjacent to the first aluminum layer; and a carbon composite layer adjacent to the first glass composite layer, and opposite to the first aluminum layer. A method of manufacturing a material system may include: stacking an aluminum layer, glass composite layer that may include thermoplastic prepreg plies, and carbon composite layer so that the aluminum layer is adjacent to the glass composite layer, and the glass composite layer is adjacent to the carbon composite layer; and consolidating the thermoplastic prepreg plies to soften the aluminum layer. A method of manufacturing a material system may include: stacking an aluminum layer, glass composite layer that comprises thermoplastic resin, and carbon composite layer so that the glass composite layer is between the aluminum and carbon composite layers; and adjusting temperature and pressure to consolidate the stack.

A method for manufacturing a high-pressure tank includes: forming a preform by winding a carbon fiber around a liner to form a fiber layer on an outer periphery of the liner; and impregnating the fiber layer of the preform with a curable resin and curing the curable resin. When winding the carbon fiber around the liner, a metal wire together with the carbon fiber is wound around the liner.

The invention concerns a hybrid part (11) for a motor vehicle, comprising at least one metal insert (1) overmoulded in a layer of plastic or composite material (17), the insert (1) being at least partially covered on at least one of its faces (7a, 7b) by a layer of material of a given thickness; and comprising at least one relief (5) extending from one of its faces (7a, 7b). The height exhibited by the relief or reliefs (5) is less than or equal to the thickness of the layer of plastic or composite material overmoulded on said face (7a, 7b) of the insert (1), so that the contact between the reliefs (5) and the walls of the mould ensures the positioning of the insert (1) in the mould during the overmoulding operation.
