Approach

MATISSE aims to develop an integrated, validated approach to the modelling, simulation and testing of safety-critical pressurised FRP structures subjected to impact loading. The applicability of this approach also extends to FRP structures that are not subject to high internal pressure, however MATISSE will focus on pressurised ones as we have identified two classes of these structures that can be major determinants of APV safety.  

The specific tasks of the MATISSE project are:
  • Define and investigate future crash scenarios involving lightweight APV, with a special emphasis on vehicle-to-vehicle compatibility and asymmetric crashes
  • Assess the suitability of current evaluation criteria for occupant, pedestrian and partner injury prevention for these future crash scenarios involving lightweight APVs – develop new criteria where the current ones are not suitable or no current criteria exist
  • Advance a number of very promising modelling methodologies that specifically address the difficulties in modelling FRP composites in comparison to metals. Among the methodologies we seek to advance the BPRCM (bi-phase rheological composite material model) and and XFEM (eXtended Finite Element Method) approach to crack propagation and delamination
  • Apply new methodologies and material models to the investigation, design and testing of one or more FRP pressurised adaptive crash structures with regards to advanced occupant, pedestrian and partner protection
  • Apply new methodologies and material models to the investigation, design and testing of an improved FRP high-pressure storage tank for CNG fuel with regards to advanced occupant protection
  • Develop important elements of a modelling & simulation tool chain that will allow APV designers to predict and optimise the safety performance of parts – and of the whole vehicle - prior to hardware prototyping and testing.
