Abstract
The invention relates to a method for manufacturing a sandwich panel as a semi-finished product where at least one layer of a non-metallic material is positioned between at least two metallic layers. At least one of the metal layers is shaped into a three dimensional layer, and the metal layers are in direct mechanical contact to enable resistance weldability of the semi-finished product in order to connect the semi-finished product to a desired combination of solutions in a subsequent manufacturing process.
Claims17
A method for manufacturing a sandwich panel as a semi-finished product comprising:
- providing a first metallic layer;
- providing a second metallic layer, wherein the second metallic layer is shaped into a three dimensional layer having recesses and raised areas;
- at least partially filling the recesses of the second metallic layer with a non-metallic material while leaving at least a portion of the raised areas free of non-metallic material;
- covering a surface of the second metallic layer in which the recesses have been at least partially filled with non-metallic material with the first metallic layer, such that the non-metallic material is disposed between the first metallic layer and the second metallic layer;
- and bonding the first metallic layer to the second metallic layer,
- wherein the portion of the raised areas of the second metallic layer that is free of non-metallic material and the first metallic layer contact each other to enable resistance weldability of the semi-finished product for connecting the semi-finished product to an at least partially metallic product in a subsequent manufacturing process.
