Abstract
A method of forming a laminated glass structure includes introducing a continuous ribbon of flexible glass substrate having a thickness of no greater than about 0.3 mm to a substrate material. The substrate material has a coefficient of thermal expansion (CTE) that is greater than that of the flexible glass substrate. The flexible glass substrate is laminated to the substrate material at an elevated temperature. The substrate material is cooled to introduce a compressive stress across a thickness of the flexible glass substrate.

A method of forming a laminated glass structure, the method comprising:
- from a roll of a continuous ribbon of flexible glass substrate, introducing the continuous ribbon of flexible glass substrate having a thickness of no greater than 0.3 mm to a continuous ribbon of non-glass substrate material, the non-glass substrate material having a coefficient of thermal expansion (CTE) that is greater than that of the flexible glass substrate;
- continuously laminating the flexible glass substrate to the non-glass substrate material at an elevated temperature of at least about 100 degrees C.;
- and
- cooling the laminated glass structure to introduce a compressive stress across a thickness of the flexible glass substrate as the laminated glass structure passes continuously through a cooling station where the laminated glass structure is cooled.
A method of forming a laminated glass structure, the method comprising:
- shaping a substrate into a non-planar shape, the substrate comprising a non-glass material;
- and
- laminating a flexible glass substrate to the substrate while the flexible glass substrate conforms to the non-planar shape of the substrate, wherein a rolling pressure is applied to the flexible glass substrate by a programmable roller assembly that moves along an actuation path during the step of laminating.
A method of forming a laminated glass structure, the method comprising:
- introducing a flexible glass substrate as a continuous ribbon to a substrate comprising a non-glass material where the substrate of non-glass material is introduced to the flexible glass substrate as a continuous ribbon;
- forming a substrate stack including a layer of the flexible glass substrate, a layer of the substrate comprising the non-glass material and a layer of an adhesive material located between the flexible glass substrate and the substrate;
- introducing the substrate stack to a pressure zone;
- applying pressure to the substrate stack within the pressurized zone while the substrate stack is both heated and then cooled;
- and
- cutting the laminated glass structure into multiple, individual laminated glass structures.
