Mechanical Testing of Components of Cryogenic Hydrogen Tank

  • Cryogenic hydrogen tanks are important element for future hydrogen based drive technologies
  • Crash loads impose high requirements with respect to mechanical strength
  • The mechanical strength of a hydrogen tank suspension has been tested and verified for both extreme temperature points of the operational spectrum (+85°C and -196°C)
  • KRP-M provided the know-how for the design of the cryo-capable test set-up and performed the tests in a 100kN tensile testing machine
