Characterization of a DIGIMAT viscoelastic model for fiber reinforced polymers


Some differences between short and long glass fiber reinforced polymers

  • Studies on plaque including the project for Tesla
  • Gather data generated in the past on charpy/Izod with the main difference observed for the notched samples (better resistance to failure propagation)




Standard impact tests such as Charpy/Izod tests or dart (multi-axial) impact tests are mainly part of the Syensqo Core Labs capabilities. The description of the related equipment can be found in the below links (core labs wikipages):

The Brussels analytical Lab (Explorer Center, Haren) is also equipped with impact test capabilities. On top of pendulum impact tests and dart impact tests, this Lab has the capability to characterize the behavior of our polymers at high strain rates using a Very High Speed (VHS) tensile test machine. 

Brussels Labs equipmentDescription

Very High Speed (VHS) tensile test machine

  • Speed: up to 20m/s - Today, we can tests samples from 0.1/s up to 10/s and a project is ongoing to increase this range up to 100/s.
  • Temperature range: -80°C to 250°C
  • Loading modes: tensile, shear, compression
  • Strains are measured by DIC (digital image correlation) using high speed cameras (up to 1000 000 images/s) and a specific xxx pattern pasted on the samples (in-house development).


  • The samples are so-called VHS-1-20 coupons developed internally:

The VHS machine is particularly relevant for the calibration of advanced material models to run structural simulations taking into account the effect of the strain rate as well as the fiber orientation for filled materials (see "Theory and Model" section for more details).

Dart Drop Tower

  • For coupons to medium size parts
  • Energy range: 0.57 to 1800J
  • Speed range: 0.77 to 24 m/s
  • Temperature: -70°C to 200°C
  • Compatible with high speed cameras
Charpy/Izod/Tensile impact test
  • Temperature range: -50°C to 300°C
  • Energy range (hammers): 0.5 to 25J
