1. A method for producing a pressure vessel, comprising:
a) providing a liner for storing a fluid, having a cylinder region and two cap regions at opposite ends of the cylinder region;
b) wrapping the liner at the cap region and the cylinder region with a fiber material impregnated with matrix material, to produce a first fiber layer already imbued with matrix material;
c) arranging a second fiber layer around the first fiber layer, the second fiber layer having been formed by at least one braided sleeve of dry fibers, the second fiber layer saturated by the matrix material; and
d) curing or consolidating the matrix material, without supplying additional matrix material, to produce a fiber-reinforced laminate surrounding the liner.
