Abstract

A tension adhesion test is developed to measure the adhesion of a polymer interlayer to the glass plates in laminated glass. The polymer adhesive is bonded between two cracked glass plates and is loaded under a remote tension P. Typically, a peak load P* exists and its value depends on the adhesion between the polymer interlayer and the glass. The peak load P* is often used to characterize the adhesion strength of the interface. The experimental data is analyzed using a micromechanical model of debonding and simulated using finite element computation. Our analysis allow us to determine the shear and normal strength of the interface and the relation between the peak load and the mechanism of debonding.
