Drum Peel Test Fixture GZ D-25

A drum peel test fixture is used to determine the resistance of core composites to peeling loads acting perpendicular to the surface layer, in accordance with DIN 53295 or similar standards. This test fixture is suitable for core composites whose surface layer can be wound around the drum during the test. The part of the core composite that is not wound around the drum (the core and the second top layer) must be sufficiently rigid to resist bending. The drum peel test fixture can be used in all standard universal testing machines.

The GZ D-25 drum peel test fixture is characterised by a user-friendly and easy-to-operate design, as well as an extremely precise linear guide for the roller-bearing-mounted drum with end stops. The test rig has an stainless design and is made of high-alloy tool steel.
