Bullet-resistant transparent laminate composite and protection arrangement having a bullet-resistant transparent laminate composite

1. A bullet-resistant transparent laminate composite comprising:

at least two plates arranged one behind the other and at a spacing relative to each other in the direction of threat, each of said at least two plates being formed of a transparent first material with a modulus of elasticity of at least 1,500 N/mm 2 , wherein the transparent first material is a plastic material, and

at least one respective intermediate layer of a transparent second material with a lower modulus of elasticity than that of the first material, said at least one intermediate layer being between said at least two plates, wherein the transparent second material is a polyurethane (PU), a thermoplastic polyurethane (tPU), a polyvinyl chloride (PVC), or polycarbonate (PC) based material,

wherein the layer thicknesses of the plates and the at least one intermediate layer are so selected that the overall layer structure of the layer composite of plates and the at least one intermediate layer has an average modulus of elasticity which is at least 20% and at maximum 60% lower in comparison with a block made exclusively from the first material and of the same overall thickness,

wherein the laminate composite in the direction of threat is of an overall thickness in the region of 20 mm to 300 mm; and

wherein the layer thickness of the at least one intermediate layer is 3.5 mm to 7.5 mm.

2. The laminate composite according to claim 1 , wherein the thicknesses of the plates are selected to be greater in a region on the side towards the threat than in a region on the side of the laminate composite that is remote from the threat.

3. The laminate composite according to claim 1 , wherein there are provided means for carrying tensile stresses in the at least one intermediate layer in a region of the laminate composite that is remote from the threat.

4. The laminate composite according to claim 1 , wherein a pane heating means is integrated in at least one of a plate on the side of the laminate composite, that is towards the threat, and a plate on the side of the laminate composite, that is remote from the threat.

5. The laminate composite according to claim 1 , wherein the laminate composite further has a plate of polycarbonate on its side remote from the threat.

6. The laminate composite according to claim 1 , wherein the laminate composite is provided with a protection device against laser beams.

7. The laminate composite according to claim 1 , wherein the laminate composite is provided with a metal structure for electromagnetic screening.

8. A process for the production of a bullet-resistant transparent laminate composite according to claim 1 , comprising the steps of:

arranging the plates, the intermediate layer and optionally the polycarbonate plate;

surrounding the arrangement with a flexible and fluid-tight enclosure;

producing a reduced pressure in the enclosure; and

acting on the arrangement surrounded by the enclosure with pressure and temperature in an autoclave.

9. The laminate composite according to claim 1 , further comprising a plurality of intermediate layers between said at least two plates.

10. The laminate composite according to claim 9 , wherein at least one of said plurality of intermediate layers has a layer thickness of 3.5 mm to 7.5 mm.
