Abstract:
Principles and embodiments of the present disclosure relate to unique asymmetric laminates and methods that produce the laminates that have improved damage tolerance, where the laminate includes a first strengthened glass substrate having a first central tension value bonded to a second strengthened glass substrate having a second central tension value by an interlayer, where the first central tension value is less than the second central tension value.
Abstract:
A laminate structure having a first glass layer, a second glass layer, and at least one polymer interlayer intermediate the first and second glass layers. In some embodiments, the first glass layer can be comprised of a strengthened glass having first and second surfaces, the second surface being adjacent the interlayer and chemically polished and the second glass layer can be comprised of a strengthened glass having third and fourth surfaces, the fourth surface being opposite the interlayer and chemically polished and the third surface being adjacent the interlayer and having a substantially transparent coating formed thereon. In another embodiment, the first glass layer is curved and the second glass layer is substantially planar and cold formed onto the first glass layer to provide a difference in surface compressive stresses on the surfaces of the second glass layer.
