Definitions

  • the present invention relates to a pressure vessel and a method for manufacturing a pressure vessel.
  • Pressure vessels are well known, for example in the form of pressure bottles in which compressed air is stored.
  • these pressure vessels usually not only have to withstand pressure from the inside, which emanates from a fluid compressed in the pressure bottle, but also pressure from the outside, for example a dive of the submarine acts on the pressure vessel.
  • pressure cylinders made of steel are used for submarines in order to meet the loads mentioned.
  • these pressure bottles generally have such a high weight that they cannot be used to achieve a targeted balancing of a hull, for example the submarine, without additional balancing weights.
  • EP0666450 A1 relates to a pressure vessel comprising a liner with a cylindrical middle part and two dome-shaped end parts, and an outer jacket enveloping the liner.
  • the present object is achieved by the pressure vessel according to claim 1.
  • the use of the fiber layer package advantageously provides reinforcement, and the preferably targeted arrangement of the area of increased material thickness increases stability or increases shock resistance.
  • the use of fibers in the fiber layer package makes it possible to realize a fiber-plastic composite which, together with the area of increased material thickness, ensures that the pressure vessel also has an increased external pressure which, for example, acts on the pressure vessel during a submarine dive, withstand.
  • the at least partial use of the fiber-plastic composite instead of a solid pressure vessel made of steel advantageously enables a weight reduction compared to the pressure vessels made of solid steel.
  • the pressure vessel is a pressure bottle that is used in a submarine and in which compressed air or a pressure fluid is stored.
  • the inliner is designed as a hollow body.
  • the inliner is shaped in such a way that the pressure vessel has an axis of symmetry and / or that the pressure vessel is adapted to its place of use in terms of its geometric configuration for better use of space. It is conceivable, for example, that the cross section of the pressure vessel is kidney-shaped or that its cross section deviates from a circular or elliptical shape.
