TL;DR: In this paper, the welding rivets are arranged: on the side turned away from the second component in a fluid-tight manner; and by foaming, casting or laminating during manufacturing the components.
Abstract: The method for joining components comprising a first component (1) made of plastic or non-ferrous metal and a second component (2) made of steel, nonferrous metal or plastic, comprises arranging welding rivets (3) made of steel in the first component in the region overlapping with the second component in openings, fixing the components in a welding position, partially applying an adhesive on the components, arranging the welding rivets in the components by riveting, bonding, form-fit locking or non-positive pressing, and welding the welding rivets directly with the second component. The method for joining components comprising a first component (1) made of plastic or non-ferrous metal and a second component (2) made of steel, nonferrous metal or plastic, comprises arranging welding rivets (3) made of steel in the first component in the region overlapping with the second component in openings, fixing the components in a welding position, partially applying an adhesive on the components, arranging the welding rivets in the components by riveting, bonding, form-fit locking or non-positive pressing, welding the welding rivets directly with the second component by resistance spot welding or the welding rivets arranged with the second component made of non-ferrous metal or plastic, and curing or hardening of the adhesive. The welding rivets are arranged: on the side turned away from the second component in a fluid-tight manner; and by foaming, casting or laminating during manufacturing the components. An independent claim is included for a composite component.

TL;DR: The FutureSteelVehicle (FSV) as discussed by the authors is an automotive Stahlforschungsprojekt, das erheblich zur Entwicklung und Einfuehrung hoeherfester (HSS) und hochfester Staehle and deren Verarbeitung beigetragen hat.
Abstract: Das FutureSteelVehicle (FSV) ist das fuenfte automobile Stahlforschungsprojekt, das erheblich zur Entwicklung und Einfuehrung hoeherfester (HSS) und hochfester (AHSS) Staehle und deren Verarbeitung beigetragen hat. Ziel ist, dass neue Stahlgueten und innovative Halbzeuge fuer zukuenftige Fahrzeuggenerationen mit alternativen und konventionellen Antrieben zur Umsetzung gebracht werden koennen, da fortgeschrittene Antriebe (Hybrid-, elektrische und Brennstoffzellen-Antriebe) radikal die Fahrzeugstrukturen und damit die Werkstoffauswahl veraendern. Das FSV verwendet zukunftsweisende CAE-Methoden mit einem Portfolio an AHSS und ultrahochfesten Staehlen (UHSS), vielfaeltige intelligente Halbzeuge und Verarbeitungstechniken. Damit soll fuer ein Elektrofahrzeug (BEV) das Gewicht der Rohkarosserie auf 188 kg reduziert werden. Die Schwerpunkte der Entwicklungsmethodik lagen auf der topologischen Analyse und Optimierung des Gesamtkonzepts, der Entwicklung von Stahl-Leichtbau-Konzepten und der Ueberpruefung des Crashverhaltens durch Simulation. Der Beitrag stellt die Schritte des Engineering-Teams im Rahmen des FSV-Projekts vor. Aktuell befindet sich das FSV-Programm in den Phase 3, bei der die entwickelten sicheren und gewichtsoptimalen Stahl-Leichtbau-Konzepte der Fahrzeugindustrie vorgestellt und den Entwicklungsabteilungen fuer eine optimale Umsetzung kommuniziert werden.

TL;DR: In this paper, the curable edge filler is poured between milled edge surfaces of component and the cavity surfaces, so that the component can be rested on flat tool surface, and the component is manufactured from lightweight core made of rigid foam and aramid honeycomb material.
Abstract: The method involves cutting the edge component to undersize, and inserting the component into the cavity of lockable casting tool, so that the component is rested on flat tool surface. The curable edge filler is poured between milled edge surfaces of component and the cavity surfaces. The component is manufactured from lightweight core made of rigid foam and aramid honeycomb material.

TL;DR: In this paper, the PU-based Sichtbauteil-Halbzeuge with abschliesend behandelten Oberflachen in so genannter Class-A-qualitat is considered.
Abstract: Die Erfindung betrifft ein Sichtbauteil, insbesondere fur die Interieurgestaltung von Fahrzeugen, wobei die Sichtbauteile in hochster Oberflachenqualitat und edler Optik gestaltet und konsequent nach dem Leichtbauprinzip ausgebildet sind. Zum Verbau der Sichtbauteile ist es notwendig, an deren Ruckseiten nachtraglich Befestigungs- und Ausrichtelemente auszubilden. Erfindungsgemas werden diese aus einem PU-System angeschaumt, ohne dass sie Bestandteil einer flachigen PU-Beschichtung auf der Ruckseite des Sichtbauteils sind. Durch den Wegfall der flachigen PU-Beschichtung kommt es zu keinem Warmeverzug am fertigen Sichtbauteil, so dass kein Einsatz von abrasiven Fullstoffen, wie zum Beispiel Verstarkungsfasern, notwendig ist. Auf diese Weise ist es moglich, Sichtbauteil-Halbzeuge mit abschliesend behandelten Oberflachen in so genannter Class-A-Qualitat einzusetzen.
