SHAPED GLASS LAMINATES AND METHODS FOR FORMING THE SAME

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 【課題】互いに異なり、互いの間に最小限の形状不一致を示すガラス基板を含む成形ガラス積層体であって、より薄いガラス基板を有する積層体を提供する。【解決手段】６３０℃の温度で第１の粘度（ポアズ）を含む第１の湾曲したガラス基板；６３０℃の温度で第１の粘度より大きい第２の粘度を含む第２の湾曲したガラス基板；並びに、第１の湾曲したガラス基板と第２の湾曲したガラス基板との間に配置された中間層を備えた積層体の実施形態が開示される。１つ以上の実施形態では、第１の湾曲したガラス基板は、第２の湾曲したガラス基板の第２の垂下深さの１０％以内の第１の垂下深さを示す。１つ以上の実施形態では、第１のガラス基板及び第２のガラス基板は、光学三次元スキャナで測定して約５ｍｍ以下の形状偏差を示すか、若しくは最小光学歪みを示す。このような積層体を含む車両の実施形態、及びこのような積層体の製造方法についても開示される。【選択図】図４
