Abstract (en)

[origin: FR2776750A1] The invention concerns a tank (1) designed to contain a fluid under pressure, having an external polyhedral shape whereof the walls constitute a sandwich structure providing it with a multidirectional resistance to pressure. The sandwich structure of the walls is formed by an outer skin (2) and an inner skin (4) made from a compact material and by a core (3) made from a porous or alveolate material, said core (3) being enclosed on its outer surface by said outer skin and on its inner surface by said inner skin (4) The wall sandwich structure is made from a honeycomb or foam material. The invention is applicable to motor vehicles.
