Patent

CA 2700549

The invention relates to a composite component having at least one first and one second sheet metal plate with at least one layer of a polymer arranged between the first and the second sheet metal plates and also a method for production of a corresponding composite component, and also the use thereof. The problem of specifying a composite component optimized with respect to the weight thereof, and which is at the same time simple to manufacture, is solved according to the invention in that the polymer layer has at least one foamed polymer layer (4) of a thermoplastic polymer, wherein the foamed polymer layer (4) has gas bubbles with a volume percentage of 1% to 80%, in particular 5% to 70%.

L'invention concerne un composant composite comprenant au moins une première et une seconde tôle métallique avec au moins une couche d'un polymère disposée entre la première et la seconde tôle. L'invention concerne en outre un procédé de production d'un composant composite correspondant ainsi que son utilisation. L'invention a pour but d'obtenir un composant composite optimisé en ce qui concerne son poids et qui soit, en même temps, simple à produire. A cet effet, l'invention est caractérisée en ce que la couche de polymère comprend au moins une couche de mousse polymère (4) formée d'un polymère thermoplastique, et en ce que la couche de mousse polymère (4) présente des bulles de gaz dans une proportion en volume de 1% à 80%, en particulier de 5% à 70%.
