Method for producing a pressure tank, a pressure tank and a pressure tank group

摘要

The present invention provides a method for producing a pressure tank for holding a pressurized fluid, comprising the steps of providing a shaped body; arranging one or more elements of a textile sheet material of reinforcing fibers on the shaped body; impregnating the reinforcing fibers, before or after the arrangement of the element or elements on the shaped body, with a thermosetting or thermoplastic resin; and curing the resin to form a composite fiber material surrounding the shaped body. The invention also provides a pressure tank for holding a pressurized fluid, comprising a hollow body which defines a storage space for the fluid, and a composite fiber material surrounding the hollow body which comprises one or more elements of a textile sheet material. The invention further provides a pressure tank group comprising a plurality of such pressure tanks.

主权项

1. A pressure tank group comprising a plurality of pressure tanks for holding a pressurized fluid, each pressure tank comprising a hollow body which defines a storage space for the fluid, and a composite fiber material surrounding the hollow body which comprises one or more elements of a textile sheet material, wherein each pressure tank extends in a longitudinal direction and has a cross-sectional circumference defining an outer contour of the pressure tank, and wherein the plurality of pressure tanks are arranged in rows and columns in a plane extending perpendicularly to the longitudinal direction, wherein the outer contours of the pressure tanks in the regions which face neighboring pressure tanks are substantially flat, and wherein the pressure tanks are connected to one another by a winding of a reinforcing fiber, wherein the winding runs in at least one plane extending perpendicularly to the longitudinal direction and the reinforcing fiber surrounds each pressure tank along its entire cross-sectional circumference, so that a force which is exerted by the pressurized fluid onto the walls of each pressure tank can be distributed by the winding over all pressure tanks in the group.
