A plurality of struts (2) made from a fiber-reinforced plastic composite material extend away from a central joint element (3). Each strut (2) can be connected to the undercarriage via this from the end facing away from the central joint element (3). For this, a connecting joint element (4) is arranged on the end of each strut (2) facing away from the central joint element (3), wherein the central joint element (3) and the connecting joint elements (4) are formed from a light metal material. The central joint element (3) and the connecting joint elements (4) are then connected to the struts (2) by an at least positive connection. The central joint element (3) and the connecting joint elements (4) are each formed from several individual elements joined together.

Abstract: A method for the production of a connecting structure for a motor vehicle involves inserting two profile elements, connected to one another by a plastic joint element, into a tool and hardening in the tool. A fiber semi-finished product with respective receivers for corresponding connecting regions of the profile elements is produced. The connecting regions of the profile elements are connected to the respective receivers of the fiber semi-finished product. The plastic joint element is produced by injecting plastic in a transfer molding process into a forming region of the tool provided for this purpose.

Abstract: The invention relates to a lightweight component for a vehicle body, which forms at least one closed frame. The lateral parts of the frame are designed as cast components and joined by at least one reinforcement profile disposed between the lateral parts, the end regions of the reinforcement profile being cast around by the cast components with a positive and adhesive connection. The invention further relates to a method for the production of such lightweight components.

Abstract: A door pillar for a supporting frame structure of a vehicle body has an upper section which extends from a vehicle roof as far as a vehicle side edge, and a lower section which extends from the vehicle side edge in the direction of a vehicle floor. In order to improve the door pillar with regard to loading and weight, it has a pillar body which extends at least in the upper section and is made of iron or iron alloy, and a pillar base which is connected fixedly thereto, extends at least in the lower section, and is made of light metal or light metal alloy.

Abstract: The present invention relates to a method for joining at least one joint part (3), provided with a through-opening (4), to a hollow profile (1), the joint part (3) being pushed with its through-opening (4) onto the hollow profile (1) up to a joint point (2), and the hollow profile (1) being expanded at least at the joint point (2). In order to improve the durability of the connection between joint part (3) and hollow profile (1), an adhesive (11) is arranged between an inner side (6) of the joint part (3) and an outer side (5) of the hollow profile (1) before the expansion in such a way that the adhesive (11) adheres to the inner side (6) and to the outer side (5) in the region of the joint point (2) after the expansion.

The sheet-metal body is produced by cutting, edging, stamping and/or plastic forming a plate-shaped metal sheet, and has a surface coating on at least one visible side, as well as at least one uncoated cut or stamped edge. The plastic body is injection-molded so that it seals the at least one uncoated or stamped edge of the sheet metal body and stiffens the sheet metal body.

Abstract: The invention concerns a steel for lightweight construction, consisting of a multiphase structure. In the case of a duplex steel, it consists of mixed ferrite (?) and austenite (?) crystals. In the case of a triplex steel, it comprises, additioally to said two phases, martensitic (?) and/or (?) phases. The volumetric weight of the inventive steel is low as a result of the high proportion of light alloys A1, Si Mn, Mg, Ga and Be. The inventive alloys have a volumetric weight of less than 7b/cm3.

Abstract: A process for producing a component with an inner fabric includes layering at least two layers of fabric one on top of the other. A layer of plastic in powder form or sheet form is introduced between respective pairs of neighboring layers of fabric. The plastic has a melting point corresponding to at most the melting point and/or the decomposing temperature of the fabric layers. The fabric layers and plastic layer are heated and pressed at a pressure greater than atmospheric pressure, during which the plastic layer is at least partially melted. After reaching the desired final form, the partially-melted plastic is cooled, thereby bonding the fabric layers to one another. The cooled plastic is arranged between the layers of fabric and, in particular, at least partially between the fibers of the fabric layers.
