Definitions
- the present invention relates to a pressure vessel and a method of 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 have to withstand not only a pressure from the inside, which emanates from a compressed fluid in the pressure bottle, but also a pressure from the outside, for example a dive of the submarine on the pressure vessel acts.
- a pressure vessel for internal or external compression in particular for a submarine, with a wall comprising an inliner and a fibrous fiber package comprising fibers, wherein the inliner is at least partially encased by the fiber layer package, wherein the The fiber layer packet has a first layer and a second layer, wherein fibers extend along a first fiber direction around the inliner in a partial area in the first layer and fibers in the second layer are formed. run long a second fiber direction, wherein the inliner for stabilizing the pressure vessel has a region of increased material thickness.
- armoring is advantageously provided by the use of the fiber layer package, and the increase in stability or an increase in shock resistance is ensured by the preferably targeted arrangement of the region of increased material thickness.
- a fiber-plastic composite which, together with the area of increased material thickness, ensures that the pressure vessel also has an increased external pressure, for example when a submarine dives onto the pressure vessel acts, withstands.
- the at least partial use of the fiber-plastic composite instead of a solid pressure vessel made of steel thereby advantageously allows a reduction in weight compared to the massively made of steel pressure vessels.
- it is a dimensionally stable pressure vessel, which is particularly preferably intended for use in maritime environments, especially in a submarine.
- the pressure vessel is a pressure bottle which 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 such that the pressure vessel has an axis of symmetry and / or that the pressure vessel is adapted for better use of space in terms of its geometric configuration at its place of use.
- the pressure vessel is designed kidney-shaped in its cross-section or that its cross-section deviates from a circular or elliptical shape.
- the pressure vessel is preferably designed to fit into the environment in which the pressure vessel is to be used.
- the pressure vessel can be used to store a compressed fluid, wherein the compressed fluid is preferably enclosed in a cavity formed by the inliner.
- regions of increased material thickness are arranged at regular intervals on the inliner and / or they are specifically arranged in certain areas on the inliner.
- the region of increased material thickness is a bulge or a protrusion on the outside of the inliner.
- the wall of the pressure vessel can be specifically strengthened at the points at which an increased tension, for example during a dive, is to be expected. It is conceivable, for example, that such areas of increased material strength are arranged at regular or irregular intervals along the axis of symmetry of the pressure vessel.
- an area of increased material thickness is arranged between the cylindrical area and the pole cap area is. It can preferably be provided that the distances of the regions of increased material thickness along the axis of symmetry in the middle region of the inliner are half as large as in the outer region.
- the fiber layer package has a third layer, wherein in the third layer fibers extend along a third fiber direction, wherein the second fiber direction and the third fiber direction differ from each other, wherein second layers and third layers along a direction perpendicular to the surface of the liner alternate direction.
- the inliner forms a mold core.
- the fiber layer package has a plurality of second layers and a plurality of third layers, wherein the individual second layers and third layers are each arranged alternately to one another.
- the fibers of the second layer follow a circulating winding and the fibers of the third layer follow a polar winding.
- the fibers of the second layer extend approximately perpendicular to the fibers in the third layer. Furthermore, it is provided that the fibers are each distributed uniformly in the first or second layer.
- the most stable possible plastic composite for reinforcing the pressure vessel can be realized in the form of the fiber layer package, wherein a layer thickness of the first layer extends up to a maximum increase of the inliner in the region of increased material thickness.
- first layer can be provided in an advantageous manner as smooth and flat surface, above which the rest of the fiber layer system is arranged.
- the fibers of the compensation layer extend at least obliquely, preferably substantially perpendicular, to the fibers of the second or third layer adjoining the first layer.
- the fibers of the first layer are preferably wound on an outer side of the inliner in accordance with a circulation winding, in particular without wrapping the region of increased material thickness.
- the fiber layer package is surrounded by a protective layer.
- the protective layer is a glass-fiber-reinforced plastic, which in particular is uniformly applied to the fiber layer package.
- the protective layer can advantageously ensure that the pressure vessel is not corroded or otherwise damaged.
- the protective layer is preferably attached to the operating environment of the pressure vessel, while For example, to its maritime environment, adapted and prevents, for example, a deposition and / or fouling, which would ultimately be responsible for a corroding.
- the Schutz devis can thus ensure in an advantageous manner, on the one hand, a fouling, ie fouling, is minimized and on the other hand by insulation or material separation corrosion is prevented.
- the protective layer isolates the fiber layer package against seawater, whereby no electric currents can flow and the electromagnetic signature is not increased.
- the protective layer can be designed such that it changes in the event of impact or point loads, for example becomes cloudy or changes color.
- This indicator function makes it easy to detect possible damage to the fiber layer package.
- the pressure vessel is stored in a pocket with zipper.
- the bag can be made of neoprene or similar material, for example. To check the indicator function, the bag can be removed, thus facilitating an inspection.
- the region of increased material thickness is designed as a reinforcing rib.
- the inliner is at least partially cylindrical in shape and / or has a Polkappen Scheme up.
- the fiber layer package is arranged in a cylindrically shaped region.
