Abstract
A penetration-resistant material having at least a double layer of woven fabric having a first layer of fabric composed of a first set of threads having 3.5 to 20 threads/cm, a linear density of at least 210 dtex, and at least 65% of the fabric weight, and a second set of threads having 0.5 to 16 threads/cm and a linear density of at least 50 dtex and a second layer of fabric composed of a first set of threads having 0.5 to 16 threads/cm and a linear density of at least 50 dtex, and a second set of threads having 3.5 to 20 threads/cm, a linear density of at least 210 dtex, and at least 65% of the fabric weight. In each layer, the second set are transverse to the first set and the ratio of the number of threads/cm of the second set to that of the first set is >1.
