## Abstract

Laminated structures comprise a metal sheet including a first face and a second face with a thickness of from about 0.5 mm to about 2 mm extending between the first face and the second face. The laminated structure further includes a first chemically strengthened glass sheet including a thickness of less than or equal to about 1.1 mm and a first interlayer attaching the first chemically strengthened glass sheet to the first face of the metal sheet. In further examples, methods of manufacturing a laminated structure comprise the steps of laminating with a metal sheet and a first chemically strengthened glass sheet together with an interlayer.

## Claims

### Claim 1

A laminated structure comprising:
a stainless-steel metal sheet including a first face and a second face with a thickness of from about 0.5 mm to about 2 mm extending between the first face and the second face;
a first chemically strengthened glass sheet including a thickness of less than or equal to about 1.1 mm, wherein the first chemically strengthened glass sheet comprises a glass sheet selected from the group consisting of aluminosilicate glass and alkali-aluminoborosilicate glass; and
a first transparent interlayer attaching the first chemically strengthened glass sheet to the first face of the metal sheet,
wherein, when the laminate is placed on a 1 inch thick flexible foam support and the first chemically strengthened glass sheet is impacted with a 535 g ball, the laminate exhibits impact energy of from 4.34 Joules to 7.49 Joules.

### Claim 2 (depends on 1)

The laminated structure of claim 1, wherein the first interlayer comprises layer of polyvinyl butyral.

### Claim 3 (depends on 2)

The laminated structure of claim 2, wherein the layer of polyvinyl butyral includes a thickness of from about 0.1 mm to about 0.8 mm.

### Claim 4 (depends on 1)

The laminated structure of claim 1, wherein the first interlayer comprises an ionomer.

### Claim 5 (depends on 4)

The laminated structure of claim 4, wherein the thickness of the first interlayer is from about 0.1 mm to about 2 mm.

### Claim 6 (depends on 1)

The laminated structure of claim 1, wherein the Young's modulus of the first interlayer is greater than or equal to 15 MPa.

### Claim 7 (depends on 6)

The laminated structure of claim 6, wherein the Young's modulus of the first interlayer is greater than or equal to 275 MPa.

### Claim 8 (depends on 1)

The laminated structure of claim 1, wherein the first chemically strengthened glass sheet comprises an acid-etched glass sheet.

### Claim 9 (depends on 1)

The laminated structure of claim 1, wherein the first chemically strengthened glass sheet includes a thickness of from about 0.5 mm to about 1.1 mm.

### Claim 10 (depends on 1)

The laminated structure of claim 1, further comprising:
a second glass sheet including a thickness of less than or equal to about 1.1 mm; and
a second interlayer attaching the second glass sheet to the second face of the metal sheet.
