Abstract
A penetration-obstructing article comprising a multiplicity of fabric layers of fibers having elongation at break of less than 8%, measured according to EN 12562, wherein there are at least two groups of fibers in at least one single fabric layer, wherein the regions of a first group have a first fabric density DG1 according to Walz of from 8% to 80% and wherein the regions of a second group have a second fabric density according to Walz of from 8% to 80% and wherein the difference between DG1 and DG2 is at least 3%.
