Definitions

  • the invention relates to a cylindrical pressure vessel made of fiber-reinforced plastic for storing gases.
  • the prior art is characterized by pressure vessels containing an inliner of metal or plastic. On the inliner, the fiber-reinforced plastic is applied by means of a winding process.
  • the axial strength is realized by longitudinal windings and the circumferential strength separated by circumferential windings.
  • the inliner serves as a scaffold for the application of the fiber-reinforced plastic and as a barrier to the permeation of gases.
  • the strength of the pressure vessel is achieved by the application of fiber-reinforced plastic.
  • the inliner increases the weight of the component.
  • a problem that precludes the use of the largest possible volume of the known container relates to the fact that the end faces of the pressure vessel are always formed as a convex dome. Due to the shape of the dome an unfavorable volume utilization is given.
  • the modification of the dome by a so-called isotensoidal shape and the modification of the fiber distribution and angle can mitigate this problem only conditionally.
  • DE 197 49 950 A shows a container with arranged in the cavity of the container with the cladding layer connected support elements, which may be formed as threads and are passed through corresponding guide channels.
  • the cladding layer is held in a specific shape and the support elements assume the function of a seam.
  • the disadvantage of these arrangements is that the reinforcing structures must absorb the pressure in all directions.
  • the resulting shape of the pressure vessel is inevitable, since the windings must be offset at an angle.
  • the general requirements for minimizing weight and volume are best met by a spherical pressure vessel in the first approach.
  • the disadvantages of a spherical pressure vessel consist in the very complex production and the unfavorable use of space in an assembly z. B. in a vehicle.
  • WO 92/06324 describes a cylindrical container.
  • the invention has for its object to develop a pressure vessel, which allows a significant improvement in the design of the pressure vessel with little effort.
  • this object is achieved in that reinforcing structures which consist of fiber strands (primarily carbon fibers) arranged uniformly distributed over the cross-sectional area of the cylindrical pressure vessel, which are exactly aligned axially and parallel between flat lids, whereby the forces caused by the internal pressure axially acting forces are received, and are enclosed by a separate circumferentially directed radially acting reinforcing layer, which receives the radially acting forces.
  • reinforcing structures consist of fiber strands (primarily carbon fibers) arranged uniformly distributed over the cross-sectional area of the cylindrical pressure vessel, which are exactly aligned axially and parallel between flat lids, whereby the forces caused by the internal pressure axially acting forces are received, and are enclosed by a separate circumferentially directed radially acting reinforcing layer, which receives the radially acting forces.
  • a container is formed by the helical winding of a largely unidirectional fiber layer, which is thickened at the ends.
  • the spirally wound Unidiretationallagen with the thickenings at the two ends of the lid or part of the lid are formed.
  • the fiber orientation of the layer is in the area transverse to the winding direction.
  • the thickenings can also be oriented in another direction or be made of a different material.
  • circumferential radially acting reinforcing layers are applied which form the end of the pressure vessels.
  • One embodiment provides, to increase the gas tightness of the pressure vessel, to wrap barrier layers between the outer layer of the axial reinforcing structures passing therethrough and the circumferential radially acting reinforcing layer, which largely overlap.
  • the lids which form the end faces of the pressure vessel, are made of suitable, lightweight metallic materials or of fiber-reinforced plastic.
  • For receiving the reinforcing structures slots can be regularly introduced at an angle, but different in depth.
  • the reinforcing materials are oriented almost completely in the direction of the forces that occur. From both properties results in a significant improvement in the weight-specific storage capacity. The production is simplified.
  • the pressure vessel after Fig. 1 arises by the arrangement of axially penetrating reinforcing structures 1, preferably impregnated monofilaments of carbon fibers or other high-strength thread-like strands, inside a cylinder. They are evenly distributed over the cross-sectional area. and are anchored in flat lids 7.
  • the cover 7 are also formed by a winding technology from the strand material or miteingewickelt from another material.
  • a metallic connection 5 for the fittings is embedded in the composite material.
  • these reinforcing strands are arranged very densely so that they can be covered with a barrier layer 3. Then the radial reinforcing layers 2 are wound on these, which form the outer end of the pressure vessel.
  • the pressure vessel after Fig. 2 and 3 is formed by winding a semifinished product, consisting of a base layer of substantially unidirectional scrim with applied at the ends of thickenings 8 as axial through reinforcing structures 1.
  • the thickenings are preferably also formed by composite material and may additionally contain barrier layers 6.
  • the semifinished product is usually preimpregnated with a matrix system.
  • the winding can be done on a metallic reinforcing tube 4, which simultaneously carries the fittings. In this case, the tube 4 must have openings for flowing through the storage medium.
  • the semifinished product is aligned so that the direction of the fibers in the base layer coincides with the axial direction of the pressure body.
  • the thickenings 8 in the edge region form the same as the axial end of the pressure hull.
  • a radially acting barrier layer 3 can be applied. On this is then oriented in the circumferential direction radially acting reinforcing layer. 2
