1. A method for producing a pressure vessel having a wall surrounding an interior space, the wall including an arrangement of first threads embedded in a matrix, and an internal structure disposed in the interior space, the internal structure including a plurality of horizontal second threads and a plurality of vertical third threads, wherein the plurality of horizontal second threads and the plurality of vertical third threads each enter the wall at two respective entry points that lie opposite one another in a pair and are anchored in the matrix, and the plurality of horizontal second threads and the plurality of vertical third threads are anchored in the matrix by interlacing with the first threads, comprising the acts of:
immersing the first threads and respective adjacent or encompassing portions of the plurality of horizontal second threads and the plurality of vertical third threads in a bath of the matrix material; and
forming concave boundary surfaces of the wall between the plurality of horizontal second threads and the plurality of vertical third threads as the matrix rises up along the plurality of horizontal second threads and the plurality of vertical third threads.
