Abstract: A car belonging to a rolling vehicle, characterized in that it includes sidewalls in the form of a single piece made from composite material including a sandwich structure provided with a first skin on the outside of the car, a second skin on the inside of the car and a closed-cell foam or honeycomb core between the skins, the walls being provided with window openings formed by interruptions in the drapes of longitudinal fibres, transverse fibres and intersecting diagonal fibres, the openings having a polygonal shape that reduces the surface area of interrupted diagonal fibres in the corners of the openings.

Abstract: A method and a toolset for manufacturing a metal liner for a composite vessel includes a mandrel configured in several mandrel elements forming support elements of primary parts constituting the metal liner.

Abstract: Temporary connection and pyrotechnic separation device with a longitudinal axis (X) comprising a pyrotechnic expansion tube (14) mounted in a space (11) formed in a connection zone between a first (2) and second assembly (4) to be separated, the second assembly (4) being formed of a stack of plies (12.1, 12.2) bonded together, the two assemblies (2, 4) being connected to each other by two metal parts (10.1, 10.2), said metal parts being fixed onto the first assembly and bonded onto the outer plies (12.1) of the second assembly (4), the bonding area between said outer ply (12.1) and the adjacent inner ply (12.2) is less than the bonding area between two inner plies (12.2) forming a fuse ply, such that, when the pyrotechnic expansion tube (14) is used, the outer ply (12.1) separates from the adjacent inner ply.

Abstract: A tank includes a tank body, a liner and a composite body spooled onto the liner, and at least one mounting, wherein the liner and the composite body are adhesively bonded together apart from in an annular joining region between the body of the tank and the mounting, surrounding the mounting.
