FIELD: protective materials, mainly for individual armor protective equipment. SUBSTANCE: protective structure uses woven face layers made of high- modulus polyamide fibres, type CBM, and back woven layers made of polyamide fibres. High-modulus polyamide fibres have a tensile strength of not below 2000 mn/sq.m and elongation at rupture of not lower than 1%. Polyamide fibres have a tensile strength of not below 600 mn/sq.m and elongation at rupture of not lower than 10%. The relation between the face and back fabric layers is within 2:1-4 in mass. EFFECT: enhanced reliability. 1 dwg, 1 tbl
