Abstract

A method of field shaping a laminated glass structure is provided. The method includes providing the laminated glass structure comprising a flexible glass sheet having a thickness of no greater than about 0.3 mm laminated to a non-glass substrate by an adhesive material. The laminated glass structure is field cut using a handheld power tool thereby forming a shaped laminated glass structure. An edge strength of a cut edge of the shaped laminated glass structure at least about 20 MPa.

Claims (26)

1. A method of field shaping a laminated glass structure, the method comprising:

providing the laminated glass structure comprising a flexible glass sheet having a thickness of no greater than about 0.3 mm laminated to a non-glass substrate by an adhesive material;

supporting the laminated glass structure on a support surface such that the non-glass substrate is located between the flexible glass sheet and the support surface;

field cutting the laminated glass structure using a cutting tool of a handheld power tool in a climb cut orientation applying a compressive force to a surface of the flexible glass sheet that is opposite the non-glass substrate in a direction of movement of the handheld power tool thereby forming a shaped laminated glass structure;

finishing a cut edge of the shaped laminated glass structures to form a finished cut edge

wherein said finishing uses abrasive particles having an average diameter of less than about ¼ of the thickness of the flexible glass sheet and

wherein a glass edge strength of the finished cut edge of the shaped laminated glass structure is at least about 20 MPa.

2. The method of claim 1 , wherein a glass edge strength of a cut edge of the shaped laminated glass structure is at least about 50 MPa.

3. The method of claim 1 , wherein the step of field cutting comprises cutting the laminated glass structure at an installation location for the shaped laminated glass structure.

4. The method of claim 1 , further comprising applying a mask along an intended cutting line on a surface of the flexible glass sheet.

5. The method of claim 1 , further comprising applying a fluid to a surface of the flexible glass sheet.

6. The method of claim 1 , wherein the handheld power tool is a router comprising a compression router bit.

7. The method of claim 1 , wherein the handheld power tool is a tile saw.

8. The method of claim 1 , wherein the handheld power tool includes a table saw.

9. A method of field shaping a laminated glass structure, the method comprising:

providing the laminated glass structure comprising a flexible glass sheet having a thickness of no greater than about 0.3 mm laminated to a non-glass substrate by an adhesive material;

supporting the laminated glass structure on a support surface such that the non-glass substrate is located between the flexible glass sheet and the support surface;

field cutting the laminated glass structure using a cutting tool of a handheld power tool in a climb cut orientation applying a compressive force to a surface of the flexible glass sheet that is opposite the non-glass substrate in a direction of movement of the handheld power tool thereby forming a shaped laminated glass structure

wherein the handheld power tool includes a cutting tool having an abrasive coating of abrasive particles having an average diameter of less than about ¼ of the thickness of the flexible glass sheet and

wherein a glass edge strength of a cut edge of the shaped laminated glass structure is at least about 20 MPa.

10. The method of claim 9 , further comprising applying a mask along an intended cutting line on a surface of the flexible glass sheet.

11. The method of claim 9 , further comprising applying a fluid to a surface of the flexible glass sheet.

12. The method of claim 9 , wherein the glass edge strength of the cut edge of the shaped laminated glass structure is at least about 50 MPa.

13. The method of claim 9 , wherein the step of field cutting comprises cutting the laminated glass structure at an installation location for the shaped laminated glass structure.

14. The method of claim 9 , wherein the handheld power tool is a tile saw.

15. The method of claim 14 , wherein the tile saw includes a cutting wheel coated with diamond powder.
