FIELD: piercing-resistant material and products made of it (bulletproof armored vests, armor plates). ^ SUBSTANCE: the material has at least a double layer of cloth material. The first layer of the cloth consists of the first set of threads of a definite linear density, making up at least 65% of the cloth mass, and of the second layer of threads with a definite linear density, the second set of threads is arranged transversely with respect to the first set of threads, and the proportion of the quantity of threads/cm in the first set to the respective value for the second set >1. The second layer of the cloth consists of the first set of threads with a definite linear density, making up at least 65% of the cloth mass, the second set of threads is arranged transversely with respect to the first set of threads, and the proportion of the quantity of threads/cm in the second set to the respective value in the first set >1. The first and second sets of threads in the first layer are oriented in parallel with respect to the first and second sets of threads, respectively, in the second layer. ^ EFFECT: simplified manufacture, absence of crossed arrangement of layers, which causes a danger of formation of weak points. ^ 14 cl, 1 dwg |
