Abstract

A penetration-resistant material is described to include at least a double layer of woven fabric, wherein the double layer includes a first layer of fabric composed of a first set of threads having 3.5 to 20 threads/cm, having a linear density of at least 210 dtex, and composing at least 65% of the first layer fabric weight, and a second set of threads comprising 0.5 to 16 threads/cm and having a linear density of at least 50 dtex, with the second set of threads being transverse to the first set of threads, and the ratio of the number of threads/cm of the first set to that of the second set is greater than 1:1, and a second layer of fabric composed of a first set of threads having 0.5 to 16 threads/cm and having a linear density of at least 50 dtex, and a second set of threads having 3.5 to 20 threads/cm, having a linear density of at least 210 dtex, and composing at least 65% of the second layer fabric weight, with the second set of threads being transverse to the first set of threads, and the ratio of the number of threads/cm of the second set to that of the first set is greater than 1:1. In the first layer of fabric at least the first set of threads, and in the second layer of f…
