Abstract
A penetration-resistant material is disclosed comprising at least one layer having a thickness D, the layer comprising a first and second layer of woven fabric, with the first and second layers being bonded together with an adhesive material, the first layer of fabric composed of a first set of threads comprising 3.5 to 20 threads/cm, having a linear density of at least 210 dtex, the filaments forming the threads having a diameter F1, and comprising at least 65% of the 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 at an angle of >0° to 90° with respect 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 being >1, and the second layer of fabric being composed of a first set of threads comprising 0.5 to 16 threads/cm and having a linear density of at least 50 dtex, and a second set of threads comprising 3.5 to 20 threads/cm, having a linear density of at least 210 dtex, and comprising at least 65% of the fabric weight, the filaments forming the threads having a diameter F2, with the second set of threads being…
