A method for resistance welding of two fiber-composite components to give a fiber-composite structure includes arranging conductive fibers within a jointing region of the two fiber-composite components, where each conductive fiber includes a carbon fiber with an electrically insulating coating. An electric current is passed through the conductive fibers to heat the jointing region to a welding temperature and melt the fiber-composite components in the jointing region. The jointing region is hardened in a manner that bonds the two fiber-composite components by way of the jointing region to give the fiber-composite structure.

Multi-ply composite charges are laid up by a multi-head laminator in a single pass, enabling high rate production of composite laminate structures such as stringers.

The invention relates to a method for manufacturing a steering wheel comprising a frame, a covering formed by a body, overmoulded onto the frame, and at least one insert, the method comprising steps aimed at: providing at least one recess in the covering, and producing the insert so that an assembly of the insert with the body of the covering allows the recess, to be at least partially covered, wherein the insert is obtained in a single piece with the body of the covering.

A tool is configured to form a composite charge into a stringer having a net shape with at least one out-of-place feature. The out-of-plane feature is formed by a shim removably attached to the tool. A family of the shims may be used to form a range of out-of-plane features having varying characteristics.

An apparatus for manufacturing a metal-resin composite by press molding includes upper and lower molds sandwiching a metal member and a resin material, a molding auxiliary component detachably fixed to the upper mold to fill part of a cavity for the resin material between the upper and lower molds, and a drive unit that vertically moves at least one of the upper and lower molds. The molding auxiliary component has a first press surface for molding the metal member. The upper mold has a second press surface for integrally molding the metal member and the resin material when the molding auxiliary component is removed. The upper and lower molds are for pressing the resin material between the second press surface and the lower mold to cause the resin to flow to fill the cavity with the resin material when the molding auxiliary component is removed.

A system for forming a composite stiffener includes a support surface to support a composite sheet and a sheet-locating device to locate the composite sheet such that a first sheet-portion is supported on the support surface and a second sheet-portion extends beyond the support surface. The system includes a separation device to separate the second sheet-portion from the first sheet-portion to at least partially form a composite charge. The system includes a layup tool including a longitudinal tool-axis and a layup surface configured to receive the composite charge. The layup surface includes a curvature along the longitudinal tool-axis. The system includes a compaction device to compact the composite charge on the layup surface. The system includes a tool-positioning device to position of the layup tool such that a compaction force, applied to the composite charge by the compaction device, is normal to the layup surface.

A method for repairing a composite structure, includes creating a repair cavity in a composite structure, placing foamable media in the repair cavity, placing a replacement skin over the repair cavity, and expanding the foamable media placed in the repair cavity.

Wing panels having composite wing skins and stringers are produced on a moving production line. The wing panels are formed on mandrels that move through workstations along the production line where laminators layup the wing skins and pick-and-place machines place stringers on the wing skins that are supplied by stringer feeder lines.

A joint structure includes a reinforcement portion that is formed by joining a composite material and a reinforcing material through an adhesive. The composite material includes a plate portion that is formed by laminating a plurality of fiber sheets, and a raised portion that is formed by laminating a plurality of fiber sheets in addition to the plurality of fiber sheets of the plate portion, and surfaces of the plate portion and the raised portion are covered with a single fiber sheet. The reinforcement portion includes the raised portion and the reinforcing material that is bonded to the raised portion through an adhesive. A first boundary between the plate portion and the raised portion and a second boundary between the raised portion and the reinforcing material are located at different positions in an in-plane direction of a laminated interface between the fiber sheets that are laminated.

Pellet having an axial direction and comprising a core that extends in the axial direction and further comprising a polymer sheath applied around said core, wherein said core comprises a plurality of filaments that extend in the axial direction; said polymer sheath is at least substantially free of said filaments; said polymer sheath comprising a plurality of filler particles; said pellet comprises at least 30%, preferably at least 35%, more preferably at least 40%, and preferably at most 60%, preferably at most 50%, of filaments by weight of the total weight of said pellet. Further disclosed is a reinforced article obtained from molding a plurality of said pellets, and a method of making such a pellet.
