Abstract: A ballistic article is comprised of high density fibers, where the linear mass density of the fibers is greater than 2000 dtex as measured by ASTM D1907 and the fibers in each layer have a total areal density greater than 100 g/m2. In one example, the ballistic article has two sheets comprising para-aramid fibers in a styrene and isoprene block copolymer matrix material.

Abstract: The invention pertains to an antiballistic panel comprising at least a first stack and a second stack, wherein the first stack has a plurality of first laminates made of a first kind of yarn and the second stack has a plurality of second laminates made of a second kind of yarn, wherein the first kind of yarn has linear density of at least 1001 dtex measured by ASTM D1907 and a filament linear density of at most 1.2 dtex measured by ASTM D1577-07, option C-2 and the second kind of yarn has a linear density of at most 1000 dtex measured by ASTM D1907 and a filament linear density of at least 1.3 dtex measured by ASTM D1577-07 option C-2.
Abstract: The invention pertains to an antiballistic panel. The panel comprises at least a first stack and a second stack, wherein the first stack has a plurality of first laminates made of a first kind of fibers and the second stack has a plurality of second laminates made of a second kind of fibers, wherein the first kind of fibers has a tensile modulus in the range of 40-85 GPa measured according to ASTM D7269 and the second kind of fibers has a tensile modulus in the range of 86-140 GPa measured according to ASTM D7269.
