Core element for sandwich elements, use of such a core element, and method for producing such a core element

A core element (20), in particular for sandwich elements, wherein

• the core element (20) has at least two hemisphere panels (16, 18) combined with each other,
• each hemisphere panel (16, 18) having uniform hemispherical elevations (12) or elevations (12) in the shape of a sphere segment or a sphere layer between planar regions (10) and spaced at a distance from one another,
• the two or in each case two hemisphere panels (16, 18) face each other with their elevations (12), and
• when two or in each case two hemisphere panels (16, 18) combined with each other, the elevations (12) of a hemispherical panel (16, 18) respectively make contact with their apex points or apex surfaces to a planar region of the other hemisphere panel (16, 18),
• wherein
• two hemisphere panels (16, 18) are connected to each other in that the elevations (12) are connected in the region of their apex points or apex surfaces with the planar region of the other or another hemisphere panel (16, 18) to which they make contact.
