DAMAGES IN THERMOPLASTIC COMPOSITE STRUCTURES: APPLICATION TO HIGH PRESSURE HYDROGEN STORAGE VESSELS

摘要

For several years, CEA has been involved in the development of type IV high pressure vessels and has obtained promising achievements. This type of vessels presents an hydrogen proof polymeric liner reinforced by a structural composite layer. Up to now, the design of this structural layer takes classically into account the material/components initial mechanical properties and safety coefficients but without any consideration of durability and damage tolerance.
