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 having at least one rotationally symmetrical, preferably conical and/or cylindrical, central portion, a plurality (N) or number (N) of individual layers (n=1 to N) which each have at least one braided or wound reinforcing fibre, preferably at least two braided or wound reinforcing fibres, 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 of the central portion, and wherein an inner starting layer (n=1) surrounds a hollow body 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 or the reinforcing fibres in each of the individual layers (n=1 to N) has or have a layer-dependent fibre angle φn relative to the axis of rotation 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 Δφn of the fibre angles φn of two successive individual layers (n=1 to N−1) are defined by the equation Δφn=φn+1−φn, where n=1 to N−1, and, for at least 80%, preferably at least 90%, of all angle differences Δφ1 to ΔφN−1, the condition Δφn≥0 is met.
