Compression Test

The compression test is used for the evaluation of the material behaviour under uniaxial compression load. Samples can be rectangular prisms, cylinders or pipe segments. The compression test on polymers has a great importance especially for building materials like polymer concrete or foams. The high relevance of these materials is attributable to their application for dampers, friction bearings or seals. Usually, stiff and semi-rigid samples are tested, such as thermoplastic injection moulding and extrusion polymers, filled and reinforced moulding materials or thermosetting plastics.

Specimen Preparation

  • Sawing
  • Grinding and polishing

Testing Conditions

  • Temperature control from -50 °C to 250 °C
  • Climate control: standard atmosphere (23 °C, 50 % relative humidity)
  • Force ranging from 5 N to 100 kN
  • Testing of stiff and semi-rigid samples, such as thermoplastic injection moulding and extrusion polymers, filled and reinforced moulding materials (short fibre, little rods or plates) or thermosetting plastics
