Testing

 

Mechanical Testing

 
  • Determination of mechanical properties (temperature range from -50 ° C to 150 º C):

    - Tensile tests.
    - Three-point bending.
    - Compression and plane strain compression tests.

  • Specific studies of fracture mechanics:

    - Determination of fracture toughness KIC and GIC
    - Determination of J0.2 and JIC
    - Determination of J-R curves.
    - Determination of essential work of fracture (EWF).

  • Hardness testing ( (Shore A and Shore D).
  • Determination of  impact resistance:

    - Pendulum Impact (Charpy, Izod, tensile-impact).
    - Dart drop impact (temperature range from -40 ° C to 150 º C).

  • Determination of fracture toughness by instrumented impact test.
  • Determination of fatigue properties.

Thermal and Rheological Tests
  • Thermal analysis using differential scanning calorimetry (DSC)
  • Dynamic mechanical thermal analysis (DMTA) in several geometries: three-point bending, single and dual cantilever, tensile, compression and indentation.
  • Determination of decomposition spectrum by thermogravimetric analysis (TGA).
  • Determination of creep- recovery curves using adapted DMTA.
  • Determination of the softening temperatures: Heat deflection under load (HDT) and indentation (VICAT).
  • Determination of gravimetric melt flow index (MFI).
  • Determination of rheological curves by capillary rheometry and dynamic oscillatory rheometry (RDA).

Other tests
  • Determination of burning behavior by cone calorimetry.
  • UL94 Flammability Test.
  • Determination of the density (Archimedes principle).
  • Determination of porosity by air pycnometer.
  • Chemical resistance tests.
  • Ageing tests.
  • Determination of ash content by combustion.
