Patent number: 11585488Abstract: A pressure vessel is disclosed comprising an inner vessel with a rotationally symmetrical middle part with an axis of symmetry along the middle part and two dome-shaped polar caps which close off the middle part, and an outer layer, wound on the inner vessel to reinforce it, made of fiber composite material made of a plurality of plies of fibers embedded in a matrix material which are arranged one above another, which run as a fiber band made of a number of fibers with a location-dependent and position-dependent fiber orientation across the inner vessel, wherein the fiber band at least in some of the plies enters from the middle part at a respective entry fiber angle relative to the axis of symmetry into the region of the dome-shaped polar caps.Type: GrantFiled: July 24, 2018Date of Patent: February 21, 2023Assignee: NPROXX B.V.Inventor: Christian Middendorf

Patent number: 11402065Abstract: The invention relates to a method for manufacturing a fibre-reinforced pressure vessel having fibre-reinforced polar caps as well as a corresponding pressure vessel having these polar caps. Therein, the method comprises the steps of applying fibre composite material onto a provided winding body having the shape of the polar caps at at least one of the ends, using a winding process; of intermediately curing the fibre composite material for dimensional stabilisation, said fibre composite material, however, subsequently still remaining chemically active for later cross-linking; of severing the fibre composite material for producing a polar cap reinforcing layer which is detached from the winding body and placed onto a liner underlay of the pressure vessel. Subsequently, the polar cap reinforcing layer is cross-linked with the fibre composite material of the pressure vessel for producing the pressure vessel reinforcing layer.Type: GrantFiled: May 8, 2018Date of Patent: August 2, 2022Assignee: NPROXX B.V.Inventors: Michael Sonnen, Frank Otremba, Thomas Bäumer, Christian Middendorf, Heinz-Willi Bickendorf

Patent number: 11162638Abstract: The invention relates to a pressure vessel with reinforced pole caps and a method for producing such a pressure vessel, which comprises an inner vessel of a cylinder-shaped central part and two dome-shaped pole caps closing the central part on both sides and an outer layer wound on the inner vessel for the reinforcement of the inner vessel against a pressure load, wherein the outer layer comprises at least one pole cap reinforcement layer and a pressure vessel reinforcement layer of fiber composite material, wherein the pole cap reinforcement layer at least partially covers the pole caps and the pressure vessel reinforcement layer covers the pole caps and the central part and a contour-stable preform is arranged as the pole cap reinforcement layer on at least one of the pole caps, preferably on both pole caps.Type: GrantFiled: January 31, 2017Date of Patent: November 2, 2021Assignee: NPROXX B.V.Inventors: Thomas Bäumer, Christian Middendorf
