SYSTEM AND PROCESS FOR FORMING CURVED GLASS LAMINATE ARTICLE USING SEPARATION MATERIAL

摘要

A co-shaped laminate is provided. The laminate includes a first curved glass substrate having a first major surface, a second major surface opposing the first major surface, a first thickness (h1), and a first viscosity (η1) of 1 x 1011 poises at a first temperature (T1); a second curved glass substrate having a third major surface, a fourth major surface opposing the third major surface, a second thickness (h2), the second thickness being less than the first thickness, and a second viscosity (η2) at the first temperature (T1); and an interlayer disposed between the first curved glass substrate and the second curved glass substrate,wherein the ratio of the first thickness to the second thickness (h1/h2) is greater than about 2.1, and wherein the ratio of the second viscosity to the first viscosity (η2/η1) is between about (h1/h2)2.55 and about(h1/h2)3.45.
