The invention herewith described refers to the ballistic protective plates and their production process and belongs to the field of protection devices for the vital parts of the body (chest and back part) protection against the grain bullets fired from the small arms – submachine guns, fully automatic firearms, and semi-automatic firearms, sniper rifles and carbines up to the 7,9 mm calibre and the protective plates are made of multi- layered composite material whereat the layer (1) protects the plate from mechanical damage, while the layer made of polyethylene and/or aramid fibres and/or ceramics absorbs energy of the projectile i.e. provides the ballistic protection, and the anti-trauma layer (3) reduces the deflection of the plate where the subject protective panels are made by assembling the pre-formed layers, in which process the assembled layers are mechanically processed in a press with and without heat.Ballistic protective plates are according to the invention, designed for classes III, III + and the class IV of the ballistic level protection prescribed by the standard NIJ 0101.04 U.S. National Institute of Justice, they can be produced as flat plates (for back protection), radius plates (curved at the specific radii of the curve) and as well as multiaxial plates adapted to the shape of the body.
