Potmacore panel bend test

Research report NO VTT-S-03561-06,
Flexural strength 100 kg/m2.

Different Potmacore panel types with different thicknesses are supported at various bearing distances, while the panel is pressed steadily with a constant load of 100 kg/m2, after which the bend is measured. There will be no permanent deformation; instead, the panel, after the test, returns to its level form.

Potmacore panel strength test

Permanent deformation after the test.

Performed by VTT Technical Research Centre of Finland

Chart for strength test:

  • vertical axel is the load on top of the panel
  • horizontal axel is the thickness (h) of the panel
  • colour of the line shows what is the supporting/
    binding interval behind the panel
