Abstract: The disclosure relates to a sandwich arrangement having at least two peripheral disposed ceramic panels and a ceramic felt which is inserted between a first and second ceramic panel, The material of the first ceramic panel is equal or different to the material of the second panel, wherein the ceramic felt is formed by a textile structure with a regularly or quasi-regularly structured woven fibres. The fibres are made of at least one material and/or composition, wherein at least one adhesive is provided between an underside of the panels and adjacent fibres.

Abstract: A method of manufacturing of a structured cooling panel includes cutting of desized 2D ceramic into tissues; slurry infiltration in the tissues by at least one knife blade coating method; laminating the tissues in a multi-layer panel, with slurry impregnation after each layer, wherein the tissue has combined fibres and/or pre-build cooling holes; drying; de-moulding; sintering the multi-layer panel, wherein part of the combined fibres burns out during the sintering process leaving a negative architecture forming the cooling structure and/or the pre-build cooling holes define the cooling structure; finishing, using of i) post-machine, and/or ii) surface smoothening/rework, and/or iii) coating application, and/or other procedures.
