Abstract: The present invention relates to lightweight components of hybrid design, also termed hybrid components or hollow-chamber lightweight components, composed of a shell-type parent body which is reinforced by means of thermoplastics and is suitable for the transmission of high mechanical loads, where particular flow aids are added to the thermoplastic in order to improve its physical properties.

Abstract: A device for the reduction of injuries in the event of a motor-vehicle accident comprises an adapter inserted between the vehicle bodywork and adjacent internal vehicle components to reduce the free space distance between the bodywork and the components. The free space distance is the shortest direct distance between a vehicle component and the adjacent bodywork which is free from other parts. The adapter changes the energy transfer involved in a collision between a person and the vehicle, in order to reduce the risk of injury to the head.

Abstract: The present invention relates to one-piece reinforcement elements consisting of an elongate shell-shaped basic body, the inner space of which has reinforcement ribs which are fixedly connected to the basic body, the reinforcement ribs consisting of plastic injection-molded on and their connection to the basic body taking place at discrete connection points via perforations in the basic body through which the plastic passes and extends over the surfaces of the perforations, and of a rigid structure reinforcement which is appended from the same plastic, by means of the same injection-molded operation, at at least one end of the basic body and which corresponds essentially to the form of the cross section of the hollow profile to be reinforced at this point of a body, an expandable adhesive material being applied over a portion of the surface of the rigid structure reinforcement and of the elongate shell-shaped basic body, the form of the rigid structure reinforcement and of the elongate basic body and also the

Abstract: The invention describes a composite component based on a sandwich structure, composed of: (a) at least two outer layers which independently of each other comprised at least one film, sheet, fiber mat and/or foam made from metal, plastic, glass, natural material and/or carbon, and (b) a core positioned between the outer layers, made from metal, plastic, natural material and/or paper having a large number of cavities, in which a casting resin system at least partially penetrates the outer layers and the core and the outer layers are bonded to the core by press molding. The composite component is characterised in that in at least one area of the sandwich structure the outer layers are pressed together and the compressed area of the sandwich structure is encapsulated with thermoplastic polymer. Composite base on a sandwich structure are obtained by encapsulating at least one area of the two outer layers. The encapsulating area is that area of the two outer layers have been pressed together.

Abstract: A process for preparing a composite hollow body article by means of injection molding is disclosed. The process includes the steps of: (a) providing a hollow body (2) having exterior surfaces (10) and interior surfaces (14), the interior surfaces (14) of the hollow body (2) defining a hollow interior (17), the hollow body (2) also having at least one opening (4, 4?) which provides fluid communication with the hollow interior (17) thereof, (b) introducing a substantially incompressible fluid (23) into the hollow interior (17) of the hollow body (2), the hollow interior (17) being substantially filled with the substantially incompressible fluid (23); and (c) injection molding thermoplastic material (3, 3?, 3?) onto at least a portion of the exterior surfaces (10) of the hollow body (2).

Abstract: A composite structural article, of preferably metal and thermoplastic material is described. The composite structural article comprises: (a) at least one reinforcing element (2) having sized openings (20); and (b) at least three profiled sections (1, 3, 4). A portion of each profiled section (1, 3, 4) is connected interlockingly with a portion of the reinforcing element (2). At least two of the profiled sections (1, 3, 4) have terminal portions each having a projecting region (5) that engages interlockingly with the sized openings (20) of the reinforcing element (2), such that a portion of the reinforcing element (2) surrounds at least partially the projecting regions (5). The profiled sections (1, 3, 4) are further joined to the reinforcing element (2) by means of thermoplastic material (11, 13) injected in the region of each interlocking connection with the reinforcing element (2).
