Comportement au feu de réservoirs composites de stockage d’hydrogène sous pression

Abstract : A type IV composite pressure vessel subjected to fire may burst because of the degradation of the outer layers, but when the inner pressure is less than a critical value, leak is observed instead of burst. This phenomenon is due to the heat transfer through the composite shell which leads to liner melting. In order to characterize this failure mechanisms, engulfing fire tests have been performed in the framework of the FireComp project whose objective is to understand and simulate the fire performance of hydrogen storage. An experimental set-up has been implemented to expose the cylinders to fire by the means of gas injectors. A complete instrumentation of the tank was implemented to follow the behavior of its envelope during and after the fire using thermocouples located inside its composite wall, and pressure measurement inside the vessel. A simple Finite Element model has been developed to simulate the coupled effects of mechanical damage and temperature. This approach accurately predicts the time leading to burst of the composite tank, as well as the transition between burst and leak.
