What is Peel Testing in materials test and how does it work? (IKB-032)
Peel Testing is a slow perpendicular (usually 90 or 180 degrees) pull that is applied to the work sample with a “peel like” movement involved.
For peel testing, a tweezer pull cartridge is required; once the cartridge has been installed you will be able to select “Peel Test” as a test option. This test is essentially the same as a standard tweezer pull test but with the addition of XY movement in a chosen direction, whilst the tool is applying the upward load.
The image shows a standard peel test, the tweezer jaws close onto the item being tested (top image), the Z axis then moves upwards and the XY stage moves in a specified direction (right image).
Once a peel test has been carried out and completed then a results graph will be available. The second image shows the force displacement results of a sample peel test performed on a Dage4000Plus Materials Test system.
Essentially anything that needs to have its adhesive strength measured will be peel tested. Examples can include:
- Adhesive testing; tapes, epoxy etc
- Solar panel testing; testing of interconnects, different types of laminates etc…
NOTE: To Perform a Peel test you will require a tweezer pull cartridge and a motorised XY Stage.
