Patent ID: 8470111

Claim:
Method for the production of a composite component comprising at least one first and at least one second sheet metal plate with at least one layer of a polymer arranged between the at least one first and the at least one second sheet metal plate, the method comprising: unwinding a first metal strip from a first coil and unwinding a second metal strip from a second coil, applying a thermoplastic foamed polymer layer comprising a PA6 polyamide with a proportion of grafted polyethylene and a reactive copolymer onto at least one of the first or second metal strips, producing the foamed polymer layer by physically introducing gas bubbles into a polymer melt, so that the foamed polymer layer comprises gas bubbles with a volume percentage of 1% to 80%, binding the first metal strip, the thermoplastic foamed polymer layer and the second metal strip to one another through temperature and exertion of pressure and winding a linear composite component that is produced onto a coil or cutting the linear composite component into sheet composite components.
