BALLISTIC STABLE ITEMS Russian patent published in 2015 - IPC F41H5/04 

FIELD: armaments and ammunition.

SUBSTANCE: group of inventions relates to ballistic stable item, package of combined plates, and method of manufacturing of the ballistic stable item. Item and package contain reinforcement elements of linear tension, at that direction of elements of the linear tension inside the package is not unidirectional. Some elements of the linear tension are elements of linear tension containing high-molecular polyethylene, and some of elements of linear tension contain aramid. From the impact side the specified package contains first layer that has over 50 wt % of the polyethylene elements of linear tension, and second layer containing over 50 wt % of aramid elements of linear tension, at that wt % are calculated based on total weight of elements of linear tension in the layer excluding binding material. The polyethylene elements of linear tension can be tapes. The method includes stages of plates submission, plates packing and jointing, at least some plates with each other.

EFFECT: increased protection and integrity keeping of the protection panel.
