Abstract

A transparent glass/plastic material composite pane, comprising at least one transparent plastic pane, at least one glass pane and according to demand an adhesion-promoting intermediate layer between the glass pane and the plastic pane, the glass pane being a glass film of a layer thickness of from 30 to 1,000 μm.

Claims

1. A transparent glass/plastic material composite pane, comprising at least one transparent plastic pane, at least one glass pane and an adhesion-promoting intermediate layer between the glass pane and the plastic pane, wherein the glass pane is a glass film of a layer thickness of from 300 to 700 μ

m, and the adhesion-promoting intermediate layer is elastic to thereby equalize different thermal expansions of the plastic pane and the glass pane.

2. A composite pane according to claim 1, wherein the glass film is prestressed.

3. A composite pane according to claim 2, wherein the prestressing of the glass film is generated by chemical hardening.

4. A composite pane according to claim 1, wherein the plastic pane has a thickness of at least 1 mm.

5. A composite pane according to claim 1, wherein the adhesion promoting intermediate layer is a transparent adhesive comprising an adhesive resin, or a transparent adhesive film.

6. A composite pane according to claim 1, comprising at least one layer sequence of a glass film, an adhesion-promoting intermediate layer, a plastic pane, a second adhesion-promoting intermediate layer and a second glass film.

7. A composite pane according to claim 1, wherein the transparent plastic pane is a polycarbonate, copolycarbonate, polyester carbonate, copolyester carbonate, poly(meth)acrylate or polymethyl(meth)acrylate plastic material.

8. A composite pane according to claim 1, wherein the plastic pane is a thermoplastic polymer.

9. A composite pane according to claim 1, wherein the plastic pane is produced by direct polymerization of a plastic resin between two adjoining glass films, the interior surfaces of the glass films being provided with an adhesion-promoting layer.

10. A composite pane according to claim 1, further comprising at least one functional coating.

11. A composite pane according to claim 10, wherein said functional coating is at least one of an electrically conductive layer, a thermal insulation layer and an electrochromic system.

12. A composite pane according to claim 1, having a curved surface.

13. A composite pane according to claim 6, further comprising at least one functional coating.

14. A composite pane according to claim 13, wherein said functional coating is at least one of an electrically conductive layer, a thermal insulation layer and an electrochromic system.

15. A composite pane according to claim 6, having a curved surface.
