Abstract: The invention relates to a fibre-reinforced pressure vessel (1, 6) comprising a rigid gas- of fluid-tight body (2, 7, 13, 19) overwound with fibre filaments (3, 10,11, 18), whereby the fibre filaments are wound such that at least a number of fibre filaments can freely move with respect to one another and when the pressure vessel is under internal pressure the fibre filaments are loaded exactly in their longitudinal direction. The invention also relates to a method of manufacturing a fibre-reinforced pressure vessel whereby no matrix material (for example, resin) is used so that at least a number of fibre filaments would be incorporated in a matrix for that section of the pressure vessel in which the fibre filaments can freely move with respect to one another.

Abstract: A vessel for containing a fluid is provided. A composite wall encloses the fluid chamber and is connected, at at least one location, to a shaft-like body which traverses the fluid chamber and extends through the composite wall. A sealing ring is further provided to which the composite wall is connected at the connection location(s) and is slidable around the shaft-like body, subject to being limited in at least one axial direction by a stop means.

Abstract: A wheel-shaped pressure-resistant vessel for storing gaseous, liquid or liquefied fuel and which has a substantially rigid shape. Specifically, the vessel contains a substantially continuous shell of a fiber-reinforced resin. The shell has a central opening, an inner lining and an axial reinforcement member. The shell has a substantial mechanical equilibrium shape such that the axial member is situated in a central opening. The axial member contains an inner member and two end plates, with each of the end plates fixing the shell to the inner member. Further, the axial member is attached, through both end plates, to the shell such that outer surfaces of the shell are pulled towards each other, thus reinforcing the vessel and maintaining the vessel, even while it is pressurized, in its wheel-like shape.
