Abstract

Provided is a laminated glass ( 10 ), including: a core material ( 11 ) including a resin sheet ( 12 ); and a first glass sheet ( 13 a ) and a second glass sheet ( 13 b ) each being laminated on respective surfaces of the core material ( 11 ) via an adhesive layer ( 15 a ) or ( 15 b ). Each of thicknesses of the first glass sheet ( 13 a ) and the second glass sheet ( 13 b ) is smaller than a thickness of the core material ( 11 ). The first glass sheet ( 13 a ) has a cover sheet ( 14 ) made of a resin laminated on an outer surface thereof via an adhesive layer ( 15 c ). With this, the laminated glass has a light weight, and its partial breakage due to collision with a flying object can be suppressed. Each of the thicknesses of the first glass sheet ( 13 a ) and the second glass sheet ( 13 b ) is preferably ⅕ or less of the thickness of the core material ( 11 ).

Claims (18)

1. A laminated glass, comprising:

a core material including a resin sheet;

a first glass sheet laminated on a first surface of the core material via an adhesive layer; and

a second glass sheet laminated on a second surface of the core material via an adhesive layer,

wherein a thickness of the first glass sheet and a thickness of the second glass sheet are smaller than a thickness of the core material,

wherein the first glass sheet has a cover sheet made of a resin laminated on an outer surface thereof via an adhesive layer, and

wherein the thickness of the first glass sheet is larger than the thickness of the second glass sheet.

2. The laminated glass according to claim 1 , wherein each of the thicknesses of the first glass sheet and the second glass sheet is ⅕ or less of the thickness of the core material.

3. The laminated glass according to claim 1 , wherein a thickness of the cover sheet is from 0.1 mm to 5 mm.

4. The laminated glass according to claim 1 , wherein the cover sheet comprises a protective film on an outer surface thereof.

5. The laminated glass according to claim 1 , wherein the core material consists of the resin sheet.

6. The laminated glass according to claim 1 , wherein the core material further comprises at least one sheet-shaped member made of a resin laminated on the resin sheet via an adhesive layer.

7. The laminated glass according to claim 6 , wherein the at least one sheet-shaped member made of the resin is formed of a material different from a material of the resin sheet.

8. The laminated glass according to claim 1 ,

wherein the resin sheet is formed of polycarbonate, acrylic, or polyethylene terephthalate, and

wherein the cover sheet is formed of polycarbonate, acrylic, or polyethylene terephthalate.

9. The laminated glass according to claim 1 , wherein each of the first glass sheet and the second glass sheet is an alkali-free glass sheet.

10. A vehicle comprising at least one window including the laminated glass according to claim 1 .
