Safe application of composite materials – mechanical characterization

© Fraunhofer IWM

The mechanical properties of composite materials with polymer, metal or ceramic matrices are determined under operational conditions – be it quasi-static, cyclical or dynamic loads under tensile, compressive, shear or flexural loads. We perform standardized tests and can define testing concepts that are appropriate to the particular demands of the materials. The objective is to determine:

  • Limitations, stiffness and strength
  • Parameters for material and component simulation
  • Relationship between manufacturing, microstructure and properties
  • Material and component optimization
