GLASS-PLASTIC LAMINATE DEVICE, PROCESSING LINE AND METHODS THEREFOR

摘要

A laminate including a glass sheet (10) and a first polymer layer (20) laminated to a first surface of the glass sheet. The glass sheet has a thickness of from 5 to 500 microns, and the first polymer layer provides a coating factor (F) to the glass sheet, wherein the coating factor (F) is defined by the following formula F = (1 - ?ß2) / (1 + ?ß2), wherein ? = [Ep1 (1 - vg2)] / [Eg (1 - vp12)], ß = tp1 / tg, Ep1 = Young's Modulus of the first polymer, tp1 = thickness of the first polymer, vp1 = Poisson's Ratio of the first polymer, Eg = Young's Modulus of the glass, tg = thickness of the glass, and vg = Poisson's Ratio of the glass. The laminate is curved so that a second surface of the glass sheet is disposed in a concave shape; and the coating factor (F) is less than 1. A second polymer layer (30) may be disposed on the second surface of the glass sheet, and its properties may be chosen relative to those of the first polymer layer so as to reduce the maximum principle stress-due to a bending moment-in the glass as compared to a bare glass sheet.
