Lamination Bond Strength Testing Methods
topic
Laminate peel strength measurement uses T-peel test per ISO 11339 or 90-degree and 180-degree peel tests peeling separated layer arms at 100 millimetres per minute on a tensile tester, measuring peel force in Newtons per 50 millimetres width at defined temperature and peel rate conditions, with minimum peel strength specifications of 20 to 50 Newtons per 50 millimetres width being typical for technical textile laminates and higher specifications for automotive and medical applications.
Role
Verifies laminate bond integrity against the minimum peel strength required for delamination resistance during end-use application by providing the quantitative adhesion measurement that determines whether the lamination process has achieved adequate bond strength, with peel strength testing being the primary quality control test for all adhesive lamination operations and the acceptance criterion for laminate specification compliance in technical textile qualification.
