The materials tested and investigated are derived from the reference case study defined during an initial workshop. It consists of 5 polypropylenes grades. A reference rubber grade used for aging problematic is also characterized.

Work description. The following work tasks are included:

  • Tg assessment
  • Tensile testing
  • Compression testing for model calibration
  • Microstructural analyses to track damage
  • Crack initiation and propagation in the polymer systems
  • Definition of the case study/experimental procedure
  • Testing on reference demonstrators
  • Results analyses/suggestions for improvements
  • Models for polymeric materials at low temperature
  • Effect of low temperature on ageing of polymers
