A glass sheet composite having two or more glass sheets and a liquid layer between at least a pair of glass sheets out of the glass sheets, wherein a thickness of the liquid layer is 1/10 or less of a total thickness of the pair of glass sheets when a total thickness of the pair of glass sheets is 1 mm or less, and 100 μm or less when the total thickness of the pair of glass sheets is more than 1 mm.

The present disclosure relates to bullet-resistant laminated glass having at least three sheets of glass. One of the sheets of glass faces the impact side as a cover sheet, and one sheet of glass is formed as a closure sheet facing away from the impact side. Between the cover sheet and the closure sheet, one or more intermediate sheets are disposed, these sheets of glass being connected to each other by composite layers. The composite layers are formed by flexible and dimensionally unstable films and/or cast compounds. The composite layers do not consist of polycarbonate, polyurethane or polymethylmethacrylate. In order to prevent splinter output on the rear side, this glass composite has a closure sheet on the rear side consisting of thermally or chemically prestressed glass.
