Abstract
A process for the preparation of a laminate of at least one metal layer and at least one layer of flexible graphite includes producing a non-detachable bond between the graphite and the metal without using a mechanical anchoring device and without using a known adhesive. Initially, a contact surface-active agent from the group including organosilicon compounds, perfluorinated compounds and metal soaps is applied in a thin layer to at least one of the surfaces to be bonded. Then the surfaces to be bonded are brought into contact and bonded together by the action of pressure and heat.
