The investigations deal with the experimental characterization on the structural deformation of type IV pressure vessels subjected to internal pressure. For the widespread use of hydrogen technology in transport industries, the development of cost-effective storage systems is an important step. State of the art in the field of hydrogen storage are type IV pressure vessels, consisting of a polymeric liner and an enforcing winding of carbon fiber-reinforced plastic (CFRP). Regarding the structural optimization, the experimental validation of numerical simulations is a necessity for the development of material-optimized and reliable pressure vessels.

In a newly developed test chamber subscale vessels are subjected to internal pressure. At defined pressure levels the vessel is scanned from three sides. Therefore the vessel’s deformation is recorded and analyzed with regard to the corresponding pressure level. Consequently, the overall structural deformation, as well as locally varying strain distributions can be detected, analyzed and assessed regarding their influence on the vessel’s performance. The results can be used for the validation of numerical simulations as well as for the optimization of manufacturing processes with respect to the material usage.
