Abstract: A pressure vessel and a method for producing a pressure vessel are provided. The pressure vessel has a liner and a fiber-reinforced laminate, which surrounds the liner and has a first fiber layer and a second fiber layer, which are incorporated in a matrix material. The method includes: a) providing the liner for storing a fluid, having a cylindrical region and two cap regions at opposite ends of the cylindrical region, b) wrapping a fibrous material impregnated with matrix material around the liner at the cap regions and the cylindrical region to produce the first fiber layer, which is already permeated with matrix material, c) arranging the second fiber layer around the first fiber layer, wherein the second fiber layer is formed by at least one braided sleeve of dry fibers, and d) curing or consolidating the matrix material without supplying additional matrix material to produce the fiber-reinforced laminate.

Abstract: A method for producing a braided preform, includes the steps of: a) creating a braided sleeve from filler threads and braiding threads in a braiding process, for which purpose the filler threads and braiding threads are taken off thread accumulators, b) feeding a core to the braided sleeve, c) continuing the braiding process, wherein the core is advanced such that it is braided along its length, wherein, during step c), the take-off of at least one filler thread is blocked such that the at least one filler thread is pulled out of at least one section of the braided sleeve surrounding the core.
