Title
(DE) VERFAHREN UND VORRICHTUNG ZUR HERSTELLUNG EINES VERBUNDBAUTEILS
(EN) METHOD AND DEVICE FOR MANUFACTURING A COMPOSITE COMPONENT
(FR) PROCEDE ET DISPOSITIF POUR LA FABRICATION D'UN ELEMENT COMPOSITE
Abstract
(DE)
Bei einem Verfahren zur Herstellung eines Verbundbauteils (19), das aus einem Aluminiumblech (7) und einer Aluminiumschaumschicht (12) besteht, wird schmelzflüssiger Aluminiumschaum (4) direkt auf das vorgewärmte Aluminiumblech (7) aufgebracht. Hierdurch kommt es zu einer Diffusionsverschweißung zwischen Aluminiumblech (7) und Aluminiumschaum (4) und damit zu einer haltbaren Verbindung. Gegenüber der nachträglichen Verklebung von Aluminiumschaumplatten und Aluminiumblech zeichnet sich das erfindungsgemäße Verfahren durch hohe Wirtschaftlichkeit aus.
(EN)
The invention concerns a method of manufacturing a composite component (19) consisting of an aluminium sheet (7) and a layer (12) of aluminium foam. Molten aluminium foam (4) is applied directly to the pre-heated aluminium sheet (7), thus producing a diffusion-weld joint between the aluminium sheet (7) and the aluminium foam (4) and hence a durable bond. Compared with the adhesive bonding of aluminium-foam panels and aluminium sheets, the method proposed by the invention is extremely cost-effective.
(FR)
Dans un procédé pour la fabrication d'un élément composite (19) se composant d'une tôle d'aluminium (7) et d'une couche de mousse d'aluminium (12), la mousse d'aluminium en fusion (4) est directement appliquée sur la tôle d'aluminium préchauffée (7), ce qui provoque un soudage diffusif entre la tôle (7) et la mousse d'aluminium (4) et, par conséquent, une liaison durable. Comparé à un collage postérieur de plaques de mousse d'aluminium et de tôle d'aluminium, le procédé décrit dans cette invention est caractérisé par une haute rentabilité.
