T-Peel Adhesion Test

T-peel tests determine the relative peel resistance of adhesive bonds between thin flexible adherends using a T-type specimen. A ‘flexible’ adherend is one that bends through 90 degrees without breaking or cracking. T-peels are a form of tensile testing and are performed upon two flexible substrates that have been bonded together and placed into peel test grips. One substrate should stick up while the other points down so that the bonded area sticks out horizontally and the entire setup forms a “T” shape. T-peel tests help evaluate environmental durability of adhesively bonded systems and are particularly suited to testing thin aluminum alloys. A benefit to peel testing adhesives is that specimen costs run relatively low. When reviewing tests results, note that the average peeling load per unit length/width defines peel strength. It is common to peel test adhesives according to international standards. ASTM F88 is one of the more typical standards used to T-peel test adhesives.
