    Abstract

    A vehicle composite glass includes an outer pane, an inner pane, at least one polymeric intermediate layer which is arranged between the outer pane and the inner pane, and a textile film which includes a textile in a plastic matrix, wherein the textile film is adhered on a sub-region of the outer pane or the inner pane of the vehicle composite glass or is laminated in a sub-region between the polymeric intermediate layer and the outer pane or the inner pane. The vehicle composite glass has an attractive design with, at the same time, increased mechanical stiffness. The textile film can also serve as visual cover such that the otherwise customary black masking print is not required.

    4. The vehicle composite glass according to claim 1, wherein the textile film is a carbon fiber film.

    5. The vehicle composite glass according to claim 1, wherein the textile film is opaque.

    6. The vehicle composite glass according to claim 1, wherein the textile film is adhered on the sub-region of the outer pane or the inner pane of the vehicle composite glass.

    7. The vehicle composite glass according to claim 1, wherein, when the textile film is laminated between the polymeric intermediate layer and the outer pane, a polymeric bonding layer is arranged between the textile film and the outer pane, or, when the textile film is laminated between the polymeric intermediate layer and the inner pane, a polymeric bonding layer is arranged between the textile film and the inner pane.

    8. The vehicle composite glass according to claim 7, wherein the polymeric bonding layer is implemented over an entire surface in the vehicle composite glass or over part of a surface in the sub-region of the textile film.

    9. The vehicle composite glass according to claim 1, wherein the textile film is positioned in an edge region of the vehicle composite glass.

    10. The vehicle composite glass according to claim 1, wherein the textile film is frame-shaped.

    11. The vehicle composite glass according to claim 1, wherein two or more textile films are, in each case, adhered on a sub-region of the outer pane or the inner pane of the vehicle composite glass or are, in each case, laminated in a sub-region between the polymeric intermediate layer and the outer pane or the inner pane.

    12. The vehicle composite glass according to claim 1, wherein the outer pane and the inner pane have no black coating in an edge region of the vehicle composite glass.

    13. The vehicle composite glass according to claim 1, wherein the vehicle composite glass further includes a functional element or an additional functional layer.

    14. The vehicle composite glass according to claim 1, wherein the vehicle composite glass is a rear window, side window, windshield, or roof panel.

    15. A method comprising utilizing a vehicle composite glass according to claim 1 as a roof panel of a motor vehicle.

    16. The vehicle composite glass according to claim 2, wherein the fibers are selected from carbon fibers, glass fibers, or aramide fibers.

    17. The vehicle composite glass according to claim 9, wherein the textile film is arranged circumferentially around the entire edge region of the vehicle composite glass.

    Description

    [0050] The invention is further explained in the following using nonrestrictive exemplary embodiments and referring to the accompanying drawings. The drawings are schematic and not to-scale. They depict:

    [0051] FIG. 1 a plan view of a textile film,

    [0052] FIG. 2 a textile film as a rolled product,

    [0053] FIG. 3 a plan view of a vehicle composite glass according to the invention,

    [0054] FIG. 4 a cross-section of a detail of a vehicle composite glass according to the invention, and

    [0055] FIG. 5 a cross-section of a detail of another vehicle composite glass according to the invention.

    [0056] FIG. 1 depicts a plan view of a textile film 4 in the form of a carbon fiber film as it is commercially available. The carbon fiber film has a woven fabric made of carbon fibers. The woven fabric is embedded a plastic matrix. The carbon fiber film is opaque. The carbon fiber film has a decorative pattern.

    [0057] FIG. 2 depicts a textile film 4 in the form of a carbon fiber film as a rolled product as it is commercially available.

    [0058] FIG. 3 depicts a plan view of a vehicle composite glass 5 according to the invention. The vehicle composite glass 5 has, circumferentially around the edge region, a textile film 4 in accordance with FIG. 1 in the form of a frame. The through-vision region 6 is situated in the central region of the vehicle composite glass 5. The frame-like textile film 4 can be laminated into the vehicle composite glass 5 (see FIG. 4) or adhered on the vehicle composite glass 5 (see FIG. 5). The textile film 4 gives the vehicle composite glass 5 a decorative appearance. The textile film is, for example, an opaque carbon fiber film. With the use of an opaque textile film, unsightly elements, such as mechanical parts, seals, glued bonds, or cables, can also be visually concealed when installed in a vehicle such that the otherwise customary visual cover by means of a black print in the edge region of the vehicle composite glass is not required. The vehicle composite glass is suitable, for example, as a roof panel for the lightweight roof structure of a car.

    [0059] FIG. 4 depicts a cross-section of a detail of the vehicle composite glass according to the invention in accordance with one variant of FIG. 3 in a sub-region that is provided with the laminated-in textile film 4. The vehicle composite glass has, in this detail, in this order, an inner pane 2, a polymeric intermediate layer 3, the textile film 4, a polymeric bonding layer 7, and an outer pane 1. The inner pane 2 and the outer pane 1 are made of soda lime glass. The polymeric intermediate layer 3 is, for example, a PVB film with a thickness of 0.76 mm. The polymeric bonding layer 7 is, for example, a PVB film with a thickness of 0.38 mm. The textile film 4 is, for example, a carbon fiber film with a thickness of 0.4 mm. As a result of laminating the textile film 4 into the composite, increased stiffness of the vehicle composite glass is achieved, in particular in the edge region or at the edges.

    [0060] FIG. 5 depicts a cross-section of a detail of the vehicle composite glass according to the invention in accordance with one variant of FIG. 3 in a sub-region that is provided with an adhered textile film 4. The vehicle composite glass has, in this detail, in this order, an inner pane 2, a polymeric intermediate layer 3, and an outer pane 1. The inner pane 2 and the outer pane 1 are made of soda lime glass. The polymeric intermediate layer 3 is, for example, a PVB film with a thickness of 0.76 mm. The textile film 4 is, for example, a carbon fiber film with a thickness of 0.4 mm. The textile film 4 is adhered with an adhesive on the outer pane 1 (adhesive layer not shown). As a result of the adhering of the textile film 4, increased stiffness of the vehicle composite glass is also achieved; however stiffening due to lamination of the textile film 4 is more significant.
