Abstract
Float glass is widely used for many applications such as windows of buildings and cars due to its properties of transparency and corrosion resistance. The float glass is usually brittle material so that it might fracture, scatter on impact loading in some accidents and damage human bodies. There is one of the ways to reduce the risk that the installing window films to the float glass and that is a reasonable way to prevent scattering and also suggests that the glass plate installed the films might enhance the strength with the increase of the adhesive force between the film and the glass. Although the strength of the glass plate is qualitatively evaluated according to JIS R 3212, we measured the strain of the impact loading during the test. On the other experiment the adhesive forces were determined for JIS A 5759 with the days and it was investigated that the more adhesive force affects the surface strain and then the strength of the float glass. The results show that the increase of the adhesive force decreases the maximum strain and also improves the gross strength of the glass plates.
