Abstract: A method for measuring mechanical strength of a pressurized gas storage tank for a vehicle is provided, the method including providing a tank having at least one opening, introducing an expandable element into the tank via the opening, connecting the expandable element to a pipe for a liquid, filling the expandable element with liquid, exerting a pressure, Pint, on all interior walls of the tank by means of the expandable element filled with liquid, measuring a possible deformation of the tank, emptying the liquid contained in the expandable element, and removing the expandable element from the tank via the opening. Also provided is a device for measuring mechanical strength of a pressurized gas storage tank for a vehicle.

Abstract: A process for winding a filament around a winding support. The winding support has a cylindrical shape with dome-shaped longitudinal ends and a roll axis, and is held by a holding device fixed to a base. The process includes the following, occurring in synchronization, feeding a filament, by means of at least one feeding device, towards the winding support, rotating the winding support with respect to the base around a pitch axis of the winding support, rotating unlimitedly the at least one feeding device around a yaw axis of the winding support with respect to the base, and/or rotating unlimitedly the winding support around the yaw axis of the winding support with respect to the base, and rotating unlimitedly the winding support with respect to the base around the roll axis of the winding support.
