A three-dimensional electroconductive mat formed of an electroconductive knitted fabric capable of homogeneously distributing electrical charges over the entire surface thereof, wherein the knitted fabric includes at least one electroconductive metal filament yarn; a composite material including such a mat, and 40 to 95% by volume of a thermoplastic and/or thermosetting polymer material.

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.

A process of producing electrically conductive pathways within additively manufactured parts and similar parts made by plastic extrusion nozzles. The process allows for a three-dimensional part having both conductive and non-conductive portions and allows for such parts to be manufactured in a single production step.

A method of preparing a stringer (101) and panel (103) lay-up comprising the steps of providing a stringer preform (303), a panel preform (508), a filler (309) and a mold (307). The mold is adapted to define an inner surface of a stringer. The method further comprises the steps of arranging the stringer preform (303) to contact the mold (307), placing filler (309) material between the mold (307) surface and stringer preform (303), and bringing the reinforcement material (303) into contact with the panel preform (508). The shape of the mold (307) is configured to control filler (309) placement and/or filler shape and/or filler volume.

In order to optimize a method for stiffening a metal component by pressing a fiber-reinforced plastic insert onto the metal component in such a way that the method can be integrated into the serial production of the car body, it is proposed that the fiber-reinforced plastic insert be picked up by means of a robot-controlled application head and pressed onto the metal component.

The invention relates to a method for producing a component (1, 2) consisting of a fibre-reinforced plastic and prepared for the welding of a metal component (4), which comprises at least one fibre element (2) impregnated with a plastic matrix, wherein at least some portions of at least one metal joining partner (1) are integrated into a fibre element, a first section of the joining partner (1) being surrounded by the fibres of the fibre element (2) such that it is in contact therewith, and a second section of the joining partner (1) projecting over a surface of the fibre element (2) or lying at least in the surface, the joining partner (1) being connected, by at least some portions, to the liquid and hardening plastic matrix, especially at least by the first section. The invention also relates to a metal joining partner for integrating into a component consisting of fibre-reinforced plastic in order to weld a metal component (4) thereto.

A system is disclosed for additively manufacturing a composite structure. The system may include a print head configured to receive a continuous reinforcement, and at least one of a matrix jet and a matrix bath configured to wet the continuous reinforcement with a liquid matrix during passage through the print head. The system may also include a coating mechanism configured to dispense at least one of metallic and ceramic particles onto the wetted continuous reinforcement during passage through the print head, and at least one cure enhancer configured to at least one of cure the liquid matrix and cause the at least one of metallic and ceramic particles to coalesce around the continuous reinforcement. The system may further include a support configured to move the print head in multiple dimensions during discharging.

An additive manufacturing system is disclosed. The additive manufacturing system may include a first print stage configured to discharge a first type of composite structure. The additive manufacturing system may also include a second print stage configured to discharge a second type of composite structure. The additive manufacturing system may further include a support configured to move the first and second print stages.

A head is disclosed for use with an additive manufacturing system. The head may include a nozzle configured to discharge multiple fiber strands oriented transversely adjacent each other relative to a travel direction of the head. The head may also include a matrix supply separately associated with each of the multiple fiber strands.

An additive manufacturing system is disclosed. The additive manufacturing system may include a plate having a plurality of print heads arranged in a grid and each configured to discharge a curable material, and at least one shuttle having a plurality of print heads arranged in a row and each configured to discharge a curable material. The additive manufacturing system may also include at least one cure enhancer associated with at least one of the plate and the at least one shuttle. The at least one cure enhancer may be configured to cure the curable material as the curable material is being discharged. The additive manufacturing system may further include at least one actuator configured to move at least one of the plate and the at least one shuttle during discharge of the curable material.
