    摘要： The invention concerns a folded core structure (100) formed from an uncut flat body, the folded core structure having a plurality of consecutive 3D-structures (1, 2) formed by plastic deformation and connecting areas (3, 4) formed by the plastic deformation, the folded core structure comprising a first primary surface and a second primary surface oriented plane-parallel to the first primary surface, wherein the first primary surface and the second primary surface are defined by a length and a width of the folded core structure, and comprising a first secondary surface extending over the entire width of the folded core structure and extending over a part of the length of the folded core structure, wherein the first secondary surface is oriented parallel to the first primary surface and wherein the first secondary surface is located at a distance from the first primary surface between the first primary surface and the second primary surface, wherein a channel for fluid flow at least along the width of the folded core structure is provided, the circumference of the channel for fluid flow being formed by the first secondary surface, the connecting areas or a part of the 3D-structures, and the first primary surface, and wherein the first primary surface and/or the second primary surface i s/a re configured such to provide dimensional stability under a compression force applied perpendicular to the first primary surface of the folded core structure. The invention also concerns a process for providing said folded core structure.
