Title:
成形ガラス積層体及びその形成方法
Document Type and Number:
Japanese Patent JP7277369
Kind Code:
B2
Abstract:
Embodiments of a laminate including a first curved glass substrate comprising a first viscosity (poises) at a temperature of 630 °C; a second curved glass substrate comprising a second viscosity that is greater than the first viscosity at a temperature of 630 °C; and an interlayer disposed between the first curved glass substrate and the second curved glass substrate, are disclosed. In one or more embodiments, the first curved glass substrate exhibits a first sag depth that is within 10% of a second sag depth of the second curved glass substrate. In one or more embodiments, the first glass substrate and the second glass substrate exhibit a shape deviation therebetween of about ± 5 mm or less as measured by an optical three-dimensional scanner or exhibit minimal optical distortion. Embodiments of vehicles including such laminates and methods for making such laminates are also disclosed.
