Peel strength, the average force required to separate two bonded materials from one another, is a property applicable to various industries including aerospace, automotive, adhesives, packaging, biomaterials, microelectronics, and more. Peel test data is used to determine the quality of the adhesive joint and, where applicable, provides information on the effects of processes and of the environment on the adhesive-adherend interface strength.

How To Measure Peel Strength

Tensile tests are used to determine how materials behave under tension load. In a simple tensile test, a sample is typically pulled to its breaking point to determine the ultimate tensile strength of the material. The amount of force (F) applied to the sample and the elongation (∆L) of the sample are measured throughout the test.

Tensile grip jaw selection plays an important role for successful mechanical tests as if specimen slippage between the jaws occurs or if the specimen breaks or tears in the jaw area testing may need to be discarded. This post covers the available jaw surface types for tensile grips and also the operation of quick-change type jaws.

For flexible electronics applications it is important to understand the behavior of electrical resistance of metal films on polymer substrates under applied tensile strain. Although the growth of resistance during tensile loading was investigated in a number of research papers, the recovery of resistance during unloading remains virtually unexplored. In this paper, substantial recovery (decrease) of electrical resistance during and after unloading is demonstrated for copper films on polyethylene terephthalate (PET) substrates subjected to a tensile strain with different peak values.
