Abstract

A flexible glass laminate structure includes a flexible glass substrate having a thickness of no more than 0.3 mm. The flexible glass laminate structure includes a flexible glass layer including the flexible glass substrate. A property control layer is laminated to the flexible glass layer. A neutral axis of the flexible glass laminate is located outside the flexible glass layer when the flexible glass layer is in a compressive bend configuration.

First claim

1 . A flexible glass laminate structure comprising:
a flexible glass layer comprising a flexible glass substrate having a thickness of no more than 0.3 mm; and a property control layer laminated to the flexible glass layer; wherein the property control layer has an effective stiffness to unit area weight ratio of between about 0.03 Nm 3 /kg and about 0.4 Nm 3 /kg; and wherein a neutral axis of the flexible glass laminate structure is located outside the flexible glass layer when the flexible glass layer is in a compressive bend configuration.

2 . The flexible glass laminate structure of claim 1 , wherein the flexible glass substrate has a glass edge strength of no less than about 100 MPa.

3 . (canceled)

4 . The flexible glass laminate structure of claim 1 , wherein the property control layer comprises more than one stiffness control layer, and at least one of the more than one stiffness control layers comprises a material having an effective stiffness to unit area weight ratio outside of a range between about 0.03 Nm 3 /kg and about 0.4 Nm 3 /kg.

5 . The flexible glass laminate structure of claim 1 comprising a greater stiffness in a first direction than in a second direction different than the first direction.

6 . The flexible glass laminate structure of claim 1 further comprising a film layer located between the flexible glass layer and the property control layer, the film layer comprising a decorative pattern thereon that is visible through the flexible glass layer.

7 . The flexible glass laminate structure of claim 1 further comprising a decorative pattern on a surface of the flexible glass substrate.

8 . The flexible glass laminate structure of claim 1 , wherein the property control layer comprises a polymer layer with a magnetized iron.

9 . The flexible glass laminate structure of claim 1 , wherein the property control layer is laminated to the flexible glass layer by an adhesive layer, and the neutral axis of the flexible glass laminate is located in the adhesive layer when the flexible glass laminate structure is rolled to an inner diameter of at most about 30 inches.

10 . A method of forming a flexible glass laminate structure, the method comprising:
laminating a flexible glass layer and a property control layer together, the flexible glass layer having a thickness of no more than 0.3 mm; and locating a decorative pattern between the flexible glass layer and the property control layer such that the decorative pattern is visible through the flexible glass layer; wherein a neutral axis of the flexible glass laminate structure is located outside the flexible glass layer when the flexible glass layer is in a compressive bend configuration.

11 . (canceled)

12 . The method of claim 10 , wherein the flexible glass layer and the property control layer are laminated together using an adhesive layer, and the neutral axis of the flexible glass laminate structure is located within the adhesive layer when the flexible glass laminate structure is rolled to an inner diameter of at most about 30 inches.

13 . (canceled)

14 . The method of claim 10 comprising providing the property control layer with more than one stiffness control layer, at least one of the more than one stiffness control layers comprising a material having an effective stiffness to unit area weight ratio outside of a range between about 0.03 Nm 3 /kg and about 0.4 Nm 3 /kg.

15 . The method of claim 10 wherein the locating the decorative pattern comprises at least one of:
locating a film layer comprising the decorative pattern thereon between the property control layer and the flexible glass layer; or
providing the decorative pattern on a surface of the flexible glass substrate.

16 . (canceled)

17 . The method of claim 10 comprising providing the property control layer with a polymer layer comprising a magnetized iron.

18 . A roll of a flexible glass laminate structure comprising:
a flexible glass layer having a thickness of no more than 0.3 mm and a property control layer laminated to the flexible glass layer; the flexible glass laminate structure wound about a center of the roll to an inner diameter of at most about 30 inches; the flexible glass layer located on an inner facing side of the flexible glass laminate structure such that a neutral axis of the flexible glass laminate structure is located outside the flexible glass layer.

19 . (canceled)

20 . The roll of claim 18 , wherein the property control layer comprises more than one stiffness control layer, and at least one of the more than one stiffness control layers comprises a material having an effective stiffness to unit area weight ratio outside of a range between about 0.03 Nm 3 /kg and about 0.4 Nm 3 /kg.

21 . The roll of claim 18 further comprising a film layer located between the flexible glass layer and the property control layer, wherein the film layer includes a decorative pattern thereon that is visible through the flexible glass layer.

22 . The roll of claim 18 further comprising a decorative pattern on a surface of the flexible glass substrate.

23 . The roll of claim 18 , wherein the property control layer comprises a polymer layer with a magnetized iron.

24 . The roll of claim 18 , wherein the property control layer is laminated to the flexible glass layer with an adhesive layer, and the neutral axis of the flexible glass laminate is located in the adhesive layer.

25 . The roll of claim 18 , wherein the flexible glass layer has an edge strength of no less than about 100 MPa.
