Abstract

A method is provided for producing a pressure vessel from a metal liner, which is reinforced at an outer lateral surface thereof by fiber composite material having a resin matrix. In at least one production step, the resin matrix of the fiber composite material is subjected to an ultrasound treatment.

First claim

What is claimed is:

1 . A method of producing a pressure vessel, the method comprising the acts of:
reinforcing a metal liner at an outer lateral surface thereof via fiber composite material having a resin matrix, and in at least one production step, subjecting the resin matrix of the fiber composite material to an ultrasound treatment.

2 . The method according to claim 1 , wherein one or more characteristics of ultrasound waves used during the ultrasound treatment are chosen to provide an increased degassing rate of enclosed air or air bubbles from the resin matrix.

3 . The method according to claim 1 , wherein the act of reinforcing the metal liner is carried out by applying the fiber composite material to the outer lateral surface of the metal liner via a winding method.

4 . The method according to claim 3 , wherein the ultrasound treatment is carried out during the winding method.

5 . The method according to claim 2 , wherein the ultrasound waves are input during the ultrasound treatment via one or more ultrasound probes coupled mechanically or acoustically to the metal liner.

6 . The method according to claim 3 , wherein the ultrasound waves are input during the ultrasound treatment via one or more ultrasound probes coupled mechanically or acoustically to the metal liner.

7 . The method according to claim 5 , wherein the one or more ultrasound probes are coupled to a respective inlet stub or outlet stub of the metal liner of the pressure vessel.

8 . The method according to claim 6 , wherein the one or more ultrasound probes are coupled to a respective inlet stub or outlet stub of the metal liner of the pressure vessel.

9 . The method according to claim 3 , further comprising the act of:
rotating the metal liner about an axis of the pressure vessel to enable the metal liner to be wound with the fiber composite material via the winding method.

10 . The method according to claim 8 , further comprising the act of:
rotating the metal liner about an axis of the pressure vessel to enable the metal liner to be wound with the fiber composite material via the winding method.

11 . The method according to claim 9 , wherein the ultrasound waves are input such that the increased degassing rate due to ultrasonic excitation occurs only in a region of an upper half shell that is at a top during rotation of the metal liner.

12 . The method according to claim 1 , wherein the ultrasound treatment of the resin matrix occurs before applying the fiber composite material.

13 . The method according to claim 1 , wherein the ultrasound treatment of the resin matrix occurs during a curing process.

14 . The method according to claim 13 , wherein the ultrasound treatment during the curing process occurs in a vacuum chamber.

15 . The method according to claim 1 , wherein the fiber composite material is composed of carbon and/or glass fibers.
