The invention relates to a method for producing a sandwich composite material (9, 9'), comprising at least two outer metal cover layers (4a, 5a, 4a', 5a', 9a, 9b) and at least one plastic layer (4b, 5b, 4c', 5c', 9c) arranged between the cover layers, wherein: at least two metal semi-finished products (4a, 5a, 4a', 5a') coated with plastic (4b, 5b, 4c', 5c') on one side are provided; in order to establish a connection between the plastic layers of the semi-finished products, at least one of the sides of the metal semi-finished products coated with the plastic is activated before the connecting occurs; and the semi-finished products are connected to each other by means of the sides of the semi-finished products coated with plastic in order to form a sandwich composite material. The problem of providing a method that ensures an improvement in the process reliability in the production of sandwich composite materials from semi-finished products coated with at least one plastic layer on one side is solved by activating the plastic layer of the semi-finished products directly from the side of the semi-finished product coated with plastic. |
