PRESSURE CONTAINER FOR STORING GASES OR LIQUIDS UNDER PRESSURES ABOVE 200 BAR

摘要

The present invention relates to a pressure container for storing gases or liquids under pressures above 200 bar, comprising an elongate storage element (1) having at least one rotationally symmetrical, preferably conical and/or cylindrical, central portion (2), a plurality (N) or number (N) of individual layers (n= 1 to N) which each have at least one braided or wound reinforcing fibre (7, 7 '), preferably at least two braided or wound reinforcing fibres (7, 7 '), wherein the individual layers (n= 1 to N) lie over one another in a local sequence along a perpendicular (S) to the axis of rotation (11) of the central portion (2), and wherein an inner starting layer (n= 1) surrounds a hollow body (4) arranged within the storage element or forms said hollow body, and wherein an end layer (n= N) arranged above the starting layer (n= 1) is provided, and wherein the reinforcing fibre (7, 7 ') or the reinforcing fibres (7, 7 ') in each of the individual layers (n= 1 to N) has or have a layer-dependent fibre angle ? relative to the axis of rotation (11') projected into the respective individual layer (n= 1 to N), wherein, proceeding from the starting layer (n= 1) to the end layer (n= N), the angle differences Δφ_η of the fibre angles φ_η of two successive individual layers (n= 1 to N-1) are defined by the equation Δφ_η = φ_η+1 - φ_η, where n= 1 to N-1, and, for at least 80%, preferably at least 90%, of all angle differences Δφ₁ to Δφ_N-1, the condition Δφ_η 0 is met.
