Through a high-pressure vessel, the effect of cryogenic operating temperatures on cfrc material properties was studied via a variety of test specimens und methods, the mathematical modelling of constitutive, thermo- and fracture-mechanical behavior as well as a Finite-Element component analysis. By use of a virtual burst test cfrc proved itself as suitable within the whole temperature spectrum. The simulated sensitivity analysis via a full fractional parameter variation of the special geometrical and material characteristics of wrapped laminates showed, among others, a significant effect from the detailed modelling of the cross-section geometry of the layer end caps on burst pressure.
