METHOD OF MAKING RADIOTRANSPARENT POLYMER-COMPOSITE ARMOUR PROTECTIVE DEVICE AND DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2020 - IPC F41H1/04 H01Q1/42 F41H5/04 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of making armoured structures and to devices for implementation of methods for their production. Method of producing a radiotransparent polymer-composite armour protective device includes forming a packet from a bulletproof ceramic screen from a multilayer polymer-composite shell of an outer splinter screen over a bulletproof ceramic screen and from multilayer polymer-composite shell of internal splinter screen below bulletproof ceramic screen made of protective reinforcing fabric impregnated with synthetic binder. Package is made by layer-by-layer moulding in matrix, the configuration of inner surface of which corresponds to configuration of outer surface of radiotransparent polymer-composite armour protective device. Layers are impregnated with synthetic binder and held until polymerisation. Bullet-proof ceramic screen is moulded in a matrix of separate modules, which are made in a device for making a bulletproof ceramic screen facing the impact element. Modules are formed in the form of triangles, or quadrangles, or hexagons, at 1/3-1/2 of their height are filled with elastic polymer binder. Modules of bullet-proof ceramic screens with shock-absorbing underlayer are laid in matrix by continuous layer with outer surface of ceramic screen on surface of outer splinter-proof screen, shock-absorbing sublayer outside, giving them any shape. Then vacuum moulding is performed by elastic polymer binder. After polymerisation, a multilayer polymer shell is formed in the matrix from layers of protective reinforcing fabric and held until polymerisation. Thermal stabilization of the packet produced in the matrix is performed. Product is removed from matrix, subjected to machining, additionally external and internal matching layers are made, which are made of weather resistant elastic polymer material with coefficient of dielectric permeability ε ≤ 2.5.

EFFECT: higher manufacturability, reduced metal consumption.
