Die Erfindung schafft ein Verbundbauteil mit einem umschäumten Einleger aus expandiertem Metall. Gegenüber herkömmlichen Einlegern aus Metall, hat der erfindungsgemäße Einleger aus expandiertem Metall verschiedene Vorteile. Insbesondere wird zur Erreichung einer bestimmten Steifigkeit des Verbundbauteils weniger Metall benötigt, was Gewichts- und Kostenvorteile hat. Femer ist aufgrund der Gitteröffnungen des expandierten Metalls eine innigere Verbindung zwischen dem Metall und dem Schaumstoff erreichbar. Dadurch lässt sich die mechanische Beanspruchbarkeit des Verbundbauteils verbessern.The invention provides a composite component with a foamed-in insert of expanded metal. Compared to conventional inserts made of metal, the insert of expanded metal according to the invention has various advantages. In particular, to achieve a certain rigidity of the composite component less metal is needed, which has weight and cost benefits. Furthermore, due to the lattice openings of the expanded metal, a more intimate bond between the metal and the foam can be achieved. As a result, the mechanical strength of the composite component can be improved.
