Abstract
A bullet-resistant transparent laminate composite () has at least two plates () arranged one behind the other and at a spacing relative to each other in the direction of threat and comprising a transparent first material with a modulus of elasticity of at least about 1,500 N/mm, and a respective intermediate layer () of a transparent second material with a lower modulus of elasticity than that of the first material between two adjacent plates (). The layer thicknesses of the plates () and the intermediate layer or layers () are so selected that the overall layer structure of the layer composite () of plates and intermediate layer or layers has a modulus of elasticity which is at least about 10% lower in comparison with a block made exclusively from the first material and of the same overall thickness.
