BALLISTIC SOFT PROTECTIVE PACK Russian patent published in 2010 - IPC F41H1/02 

FIELD: weapons.

SUBSTANCE: invention relates to personnel bullet- and splinter-proof means, particularly to soft protective packs that make a part of armor vest. Proposed pack comprises front, central and rear layers of fabric weaves made from high-strength equal-linear density warps and weft aramide threads with equal lengthwise configuration, equal density of weave and twisting factor not exceeding 4. Front and rear fabric layers consist of single equal-density layers of woven threads and with equal surface density exceeding that of every central layer to form a structure symmetric about central layers, total surface density of front and rear layers vs total surface density of central layers varying from 0.32 to 2.85.

EFFECT: higher specific ballistic strength, reduced number of layers, hence, weight, and improved operating performances.
