Motivation

With increasing energy costs and stringent emission targets aiming for 95 g/km CO2 emissions for the year 2020, material efficient lightweight design and alternative propulsion systems play an important role in today’s vehicle research and development activities. Furthermore the security of occupants is a core demand on passenger vehicles. MATISSE addresses both, electric and compressed natural gas (CNG) storage systems and an extensive use of light fibre reinforced structures.

For the reliable application of fibre reinforced polymers (FRP) in a vehicle structure the accurate prediction of the material behaviour using the finite element method (FEM) is crucial. MATISSE focuses on advancing the modelling, simulation and testing capabilities for FRP structures under dynamic loading (crash impact safety). Crash modelling tools used in the automotive industry currently do not adequately address a number of issues specific to FRP structures under these load conditions:
  • Consideration of the load history - in particular with regards to crack initiation and growth – on residual strength and stiffness
  • Non-linearity in the stress-strain behaviour for multi-axial loading
  • Anisotropy caused by fibre orientation
  • Behaviour under continuous in-plane crushing processes
