A method of manufacturing a sandwich component comprising at least two face layers and a core layer including wires of shape memory metal, the method comprising the steps of: (a) providing a pressing device having a first die part and a second die part movable relative to each other between a closed position in which they enclose a cavity and an open position in which the cavity is open to the environment, the first die part and/or the second die part being heatable, (b) providing a sandwich semi-finished product with a first cover layer semi-finished product layer made of a long-fiber-reinforced molding compound with duromer matrix, a second cover layer semi-finished product layer made of a long-fiber-reinforced molding compound with duromer matrix and between these a core layer semi-finished product layer which includes wires made of shape memory metal (c) in the open position of the pressing device , inserting the sandwich semi-finished product into the cavity , (d) moving the first and second mold parts relative to each other to the closed position , (e) pressing the first and the second tool part together so that the sandwich semifinished product experiences a certain pressing pressure, and heating the first and/or the second tool part so that the sandwich semifinished product experiences a certain processing temperature, wherein the pressing device comprises a spacer which, in the closed position , defines the minimum distance between the first and the second tool part and thus defines the minimum dimensions of the cavity , and the spacer being set in such a way that the pressing pressure in the closed position lies between a minimum processing pressure of the first and/or the second cover layer semifinished product layer and a maximum permissible limit pressure for the core layer semi-finished product layer . (a) providing a pressing device having a first die part and a second die part movable relative to each other between a closed position in which they enclose a cavity and an open position in which the cavity is open to the environment, the first die part and/or the second die part being heatable, (b) providing a sandwich semi-finished product with a first cover layer semi-finished product layer made of a long-fiber-reinforced molding compound with duromer matrix, a second cover layer semi-finished product layer made of a long-fiber-reinforced molding compound with duromer matrix and between these a core layer semi-finished product layer which includes wires made of shape memory metal (c) in the open position of the pressing device , inserting the sandwich semi-finished product into the cavity , (d) moving the first and second mold parts relative to each other to the closed position , (e) pressing the first and the second tool part together so that the sandwich semifinished product experiences a certain pressing pressure, and heating the first and/or the second tool part so that the sandwich semifinished product experiences a certain processing temperature, wherein the pressing device comprises a spacer which, in the closed position , defines the minimum distance between the first and the second tool part and thus defines the minimum dimensions of the cavity , and the spacer being set in such a way that the pressing pressure in the closed position lies between a minimum processing pressure of the first and/or the second cover layer semifinished product layer and a maximum permissible limit pressure for the core layer semi-finished product layer . <EOS>
