This creates a high thermal conductivity transverse to the pressing direction.

- the pressing can be done for example by means of an upper and a lower punch by pressure.
- the pressing can be done via an isostatic pressing.
- the isostatic pressing method is based on the physical law that the pressure in liquids and gases is uniformly propagated on all sides and impacted surfaces generates forces whose magnitudes are directly proportional to these surfaces.
- the materials to be pressed can be brought, for example, in a rubber mold in the pressure vessel of a press plant.
- the pressure which acts on all sides of the rubber mold via the liquid in the pressure vessel, uniformly compresses the enclosed materials (at least first and second layer).
- a preform containing at least the first and the second layer can be placed in the isostatic press, for example in a liquid.
- the sandwich structure can be produced.
- the high pressures in isostatic pressing for example, allow new material properties to be created in the composite material.
- one or more sheets of a rolled expanded graphite, flakes of a rolled expanded graphite and / or a graphite fabric are introduced as heat-conducting material into the sandwich structure.
- a further embodiment provides that one or more layers of a material that remains porous remain as gas-conducting layers in the sandwich structure and pressed with it.
- a plurality of sandwich structures are pressed separately from each other and then arranged in a common container.
