Title:
SHAPED GLASS LAMINATES AND METHODS FOR FORMING THE SAME
Document Type and Number:
Japanese Patent JP2023103321
Kind Code:
A
Abstract:
To provide shaped glass laminates including glass substrates that differ from one another and exhibit a minimal shape mismatch therebetween, where the glass substrates are thinner.SOLUTION: Embodiments of a laminate are disclosed, the laminate comprising: a first curved glass substrate including a first viscosity (poises) at a temperature of 630°C; a second curved glass substrate including 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. 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.SELECTED DRAWING: Figure 4
