For guaranty of quality of the non-based adhesive sheet, one kind of adhesive used in flat panel display (FPD), damage of adhesive in a laminate process should be controlled to evaluate the interface strength. Standard examinations are not suitable for evaluating the interfacial strength because measured the peel force F includes other influences of peeling. In this paper, we developed Multi Axes-driven Peel method (MAP) to measure the peel force F from 30 to 180 degrees of the peel angle. The delamination energy and the energy dissipation were evaluated considering energy balance in steady state. This delamination energy dependency on the peel angle was discussed to observe the peel front. Then peel force in a laminate process can be obtained by the Y-type peeling test. The prediction of peel force in the Y-peel test using the delamination energy and energy dissipation measured by MAP were in good agreement with the experimental result.
