Abstract

Devices and methods for producing sandwich composite materials having at least one layer of plastic disposed between at least two outer metallic covering layers may comprise providing at least two semifinished products coated with plastic on one side, activating at least one of the plastic-coated sides of the metallic covering layers directly from the side of the covering layer having the plastic-coating, and connecting the plastic-coated sides of the metallic covering layers to form the sandwich composite material. The activation of the plastic may be performed by way of a heat source that utilizes an activation medium, radiation, or plasma, for example.
