Abstract - Storage systems for compressed hydrogen used in automotive applications are internally sealed by a diffusion barrier made of polyethylene or aluminum reinforced by a layer of several millimeters thick carbon fiber composite. A layer of impact resistant glass fiber covers the pressure vessel against external impact damage on the carbon shell. For safety reasons tank systems are qualified by several standardized tests. The main reason for these tests is to ensure that no catastrophic failure of the tank could occur. Investigation on catastrophic failure of high performance composite materials was undertaken by testing and numerical simulation. Here the influence of a preload during penetration of the laminate was in-vestigated. A report of the current research is given.
