Definitions

  • the invention relates to a method for producing a pressure tank specified in the preamble of claim 1. Art.
  • Pressure tanks for storing and dispensing compressed fluid fuels are known per se.
  • WO 2017/008899 A1 shows such a pressure tank and a method for producing such a pressure tank.
  • An elongated pressure vessel is provided with at least one longitudinal end tapered towards a pressure vessel end.
  • a plurality of force introduction elements are provided, each having an oblong connection area with a tapered projection and an anchoring area, wherein an acute angle is enclosed between the respective connection sections and anchoring sections, thereby forming an undercut.
  • the force introduction elements are arranged at least indirectly with their anchoring regions on a lateral surface of the longitudinal end, so that the connecting regions are aligned at least substantially parallel to the container longitudinal axis of the pressure vessel.
  • the reinforcing layer comprises a reinforcing braid.
  • a major challenge is to embed the force introduction elements, which are also referred to as inserts, in this Arm michs layer and to anchor within this and thus in the pressure tank.
  • an elongated pressure vessel is provided with at least one tapering towards the longitudinal end in the direction of a pressure vessel end.
  • the pressure vessel may have a zylinderförmi gene central region, wherein at the longitudinal ends of each one of the tapered longitudinal ends is arranged.
  • the tapered longitudinal ends can be designed, for example in the form of so-called polar caps, so have a hemispherical or dome-like shape.
  • the pressure vessel is made of a material which is gas- and / or liquid-tight.
  • the elongated pressure container can for example be made in one piece of a thermoplastic material or steel or aluminum.
  • a plurality of force introduction elements each having an elongate connection region with a tapered projection and an anchoring region, wherein in each case between the connection region and the anchoring region enclosed an acute angle and thereby an undercut is formed.
  • the provided force introduction elements are arranged at least with their anchoring areas on a lateral surface of at least one longitudinal end, so that the connecting portions are aligned at least substantially parallel to the container longitudinal axis of the pressure vessel.
  • a reinforcing layer is made on the pressure vessel by a repeated relative movement between the pressure vessel and a trained from a reinforcing braided braided hose is performed, wherein the projections through immerse the braided tube and the braided hose hooked to the undercuts, wherein each individual layers of the reinforcing braid arranged one above the other on the pressure vessel and the force introduction elements are anchored in the reinforcing braid.
  • the braided hose is in other words, a kind of braid made of reinforcing fibers.
  • the ampli kung fibers for example, be made of carbon fibers or other materials be. Due to the relative movement between the pressure vessel according to the invention and the braided hose formed from the reinforcing braid, it is possible in a simple manner to fix or anchor the force introduction elements within the individual layers of the reinforcing web.
  • the relative movement between the pressure vessel and the braided tube takes place in a kind of oscillating movement, in which the projections of the individual force introduction elements repeatedly through the braided tube and then the relative movement between the pressure vessel and the braided tube is designed so that the braided tube to closing on the respective connecting portions of the force introduction elements is slipped and hooked to the undercuts.
  • the reinforcing layer single Lich the reinforcing braid from which the braided tube is made, without a plastic matrix is applied.
