Abstract

Ein Bauteil für insbesondere Landfahrzeuge, vorzugsweise Karosseriebauteil für Kraftfahrzeuge, bestehend aus einem metallischen Schaumwerkstoff mit einer Metallpulver und Treibmittel umfassenden aufgeschäumten porösen Schicht, und eventuell zumindest einem massivmetallischen Blech, wobei zwischen dem massivmetallischen Blech und der aufgeschäumten porösen Schicht metallische Bindungen bestehen, weist zumindest eine aus seiner Fläche (1'') erhaben ausgeprägte Kontur (1') auf, wobei die im Bereich der Übergänge zwischen der dreidimensional ausgeformten Kontur (1') und dem Flächenbereich (1'') vorkommenden Winkel (α) in einer Größenordnung zwischen 100° und 180° gehalten sind. Zu dessen Herstellung wird ein im wesentlichen flächiger metallischer Schaumwerkstoff, der mit massivmetallischen Blechen als Deckschichten versehen sein kann, zunächst zu einem einseitig endkonturierten Formhalbzeug umgeformt und das so gebildete Formhalbzeug in eine mit einer Wandung an dessen endkonturierte Seite angepaßte Aufschäumform und darin aufgeschäumt.

A component for in particular land vehicles, preferably a body component for motor vehicles, consisting of a metallic foam material with a foamed porous layer comprising metal powder and propellant, and possibly at least one solid metal plate, wherein there are metallic bonds between the solid metallic plate and the foamed porous layer, at least one from its surface (1 '') there is a pronounced contour (1 '), the angle (α) occurring in the region of the transitions between the three-dimensionally shaped contour (1') and the surface region (1 '') being of the order of magnitude between 100 ° and 180 ° are kept. To manufacture it, an essentially flat metallic foam material, which can be provided with solid metal sheets as cover layers, is first formed into a semi-finished product that is contoured on one side, and the semi-finished product thus formed is expanded into a foam mold that has a wall on its end-contoured side and is foamed therein.
