Peel Test - an overview | ScienceDirect Topics

Peel tests are also used to determine the adhesion of electrodeposits to non-conductors, where the peel strength is usually a maximum of about 500g/mm. A Hounsfield Tensometer is suitable for testing this system, but since the adhesion is low, a sensitive beam of the tensometer must be used.

How to Perform an Adhesive Strength T-Peel Test - ASTM …

Peel tests are common for tapes, labels, coatings, and other bonded materials. There are three main types of peel tests including 90 degree peel test, 180 degree peel test, and a T-Peel test. The Loop Tack test is similar in concept but is better classified as a tension test.

T-Peel Test - an overview | ScienceDirect Topics

The results from the ‘T-peel’ and the fixed-arm peel test, where the peel angle was varied as discussed above, were not significantly different. Secondly, the same rubber-toughened epoxy adhesive as was used for the ‘T-peel’ tests [ 45 ] discussed in Section 3.3 has also been studied [ 51 , 57 ] using a LEFM test specimen, i.e. the standard tapered-double cantilever-beam specimen [ 58 ].

Peel Testing - ADMET

Common peel testing definitions and keywords include: Peel strength: The average load per unit width of bond line required to gradually separate a flexible member from a rigid member over adhered surfaces. The angle between members varies with the type of peel test (T-peel, 90-degree peel, 180-degree peel, floating roller, or climbing drum).
