摘要:
The invention relates to a method for producing a fibre composite cylindrical tank (1) for containing a fluid, comprising: - a step (S0) of assembling a reusable and removable tool kit (5); - a step (S1) of applying an end fitting (91,92) to the tool kit (5), said end fitting (91,92) having an opening (911,921) large enough for removing the tool kit (5) there through after being disassembled; - a step (S2) of forming a barrier layer (2) by swaddling the assembled tool kit (5) with a breather piece (11); - a step (S3) of forming a first shell layer (3) by winding a first composite tape (12), made of a first composite material mixing fibre and resin, over the barrier layer (2); - a step (S4) of disassembling and removing the tool kit (5) through the opening (911,921). The invention also relates to a fibre composite cylindrical tank.

The present invention relates to a pressure tank arrangement for storing and discharging compressed liquid fuels and to a method for producing a pressure tank arrangement of this type. Here, force transmission elements of the pressure tank arrangement are arranged in such a way that they utilize the available installation space for pressure tank arrangements of this type in an optimum manner.
摘要:
A pressure vessel for storing liquids in bulk which forms a space for storing liquids by combining first reinforcing plates each having a creased cross-sectional structure formed by groove parts and ridge parts with at least one second reinforcing plate having a flat plate cross-sectional structure, in which part of the pressure vessel is formed by the reinforcing plates having the creased cross-sectional structure, thus allowing liquids to efficiently flow in the pressure vessel. The pressure vessel includes: a plurality of first reinforcing plates having a creased cross-sectional structure formed by a groove part and by a ridge part, the first reinforcing plates being combined with each other and forming part of the pressure vessel; and at least one second reinforcing plate combined with the first reinforcing plates and forming a remaining part of the pressure vessel, the one second reinforcing plate having a flat plate cross-sectional structure.

The invention relates to a pressure vessel (01), comprising a hollow-cylinder-shaped vessel part (04), which is made of a concrete jacket (07) and which is arranged between a vessel head (02) and a vessel base (03). The cylinder axis (06) of the hollow-cylinder-shaped vessel part (04) extends from the vessel head (02) to the vessel base (03) along the axis of the pressure vessel (01). The hollow-cylinder-shaped vessel part (04) encloses a vessel interior (05), which is closed by the vessel head (02) and the vessel base (03). In a cross-section running perpendicularly to the cylinder axis (06), the hollow-cylinder-shaped vessel part (04) has at least three extensions (08), which are distributed evenly over the circumference of the concrete jacket (07) and which extend radially outward away from the cylinder axis (06). The extensions (08) extend at least so far that, at least from the free end (09) of each extension (08), at least the free ends (09) of the two extensions (08) immediately adjacent in the circumferential direction are visible in a straight line beyond the outer surface (10) of the concrete jacket (07). Linear clamping elements (11) are arranged between extensions (08) adjacent in the circumferential direction. The linear clamping elements (11) put the hollow-cylinder-shaped vessel part (04) under a pre-load, which acts in the circumferential direction and against an overpressure in the vessel interior (05) and is directed radially from the outside toward the cylinder axis (06).
