LAMINATED STRUCTURE Russian patent published in 2006 - IPC B32B15/04 F41H5/02 

FIELD: protection of transport and stationary devices against unauthorized effects including the acts of terrorism.

SUBSTANCE: the invention is pertaining to the laminated structures and may be applied for protection of the transport and stationary devices against unauthorized actions, including the acts of terrorism. Substance of the invention is the fact, that the laminated structure contains a robust body, in which there is a protection made out of a heat-resistance material and a material, which is capable to change its phase state and possess the property to absorb heat, and the layer made out of a highly hard non-metallic material, on the outer side of which in respect to the protected object, there is a layer made out of the heat-resistant material. The protection is combined in a unified layer and is mounted on the inner side of the layer made out of a highly hard non-metallic material. Closely to the protection there is an installed base made out of no less than two layers: the first layer consisting out of material with the percent elongation of no less than 20 %, the tensile strength from 100 up to 360 MPa, the second layer made out of the material with the percent elongation no more than 25 %, tensile strength - no less than 370 MPa. All the layers are encircled by the layer made out of a resilient non-metallic material, for example, a joint filler, an elastomer or rubber. T width of the layers are chosen in the following ratios: h₁ = (0.025-0,.3)h₂,_{h3 = (l-20)h1, h4 = (0.15-0.5)h2, h5 = (0.25-2) h4, where: h1 is the thickness of the layer made out of the heat-resistant material;h2 is the thickness of the layer made out of the highly rigid non-metallic material;h3 is the thickness of the layer of protection made out of the heat-resistance material and the material changing its phase state and possessing the property to absorb heat;h4 is the thickness of the base;h5 is the thickness of the layer made out of the resilient non-metallic material. The technical result of the invention is the raised protective properties of the laminated structure due to making the effect of the floating layer resulting in the decrease of the damage of the inner layers of the structure, that allows to withstand the mechanical actions and actions of the small arms bullets, the action of the high-temperature fire with temperature up to 1000°C within one hour and more and the local actions of the high temperatures.}

EFFECT: the invention ensures the raised protective properties of the laminated structure, its capability to withstand the mechanical actions, actions of the small arms bullets, fires with temperatures up to 1000°C for one hour and more and the local actions of the high temperatures.
