Abstract: The present disclosure relates to a composite panel having a sandwich structure formed by a central core having a primary cellular structure, for example, of the honeycomb type, sandwiched between two skins. The primary cellular structure includes an array of main cells. The composite panel further includes a plurality of pins, each pin being, on the one hand, arranged to be housed and to cooperate inside a main cell and, on the other hand, formed of a secondary cellular structure having an array of secondary cells.

Abstract: The present disclosure relates to a brazing tooling for the manufacture of a part, and in particular to a tooling adapted for brazing a set of metallic parts, in particular a composite panel, in an enclosure of a brazing furnace. The tooling includes a first mold element and a second mold element clasped together and a bearing device. The first and the second mold elements respectively include a first material and a second material, the first material having an expansion coefficient greater than the expansion coefficient of the material of the set of parts, and the second material having an expansion coefficient lower than the expansion coefficient of the material of the set of parts. At the brazing temperature, constraining of the set of parts between the bearing device of the first and second mold elements is provided.
