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.
Claims20
A ballistic article comprising:
- at least one sheet comprising fibers in a polymeric matrix material, wherein the fibers have a linear mass density greater than 2000 dtex as measured by ASTM D1907 and the fibers in each sheet of the at least one sheet have a total areal density greater than 100 g/m2.
A ballistic article comprising:
- two sheets, each comprising para-aramid fibers in a styrene and isoprene block copolymer matrix material, wherein the fibers in each sheet have a linear mass density greater than 2000 dtex as measured by ASTM D 1907 and the fibers in each sheet have a total areal density greater than 100 g/m2, and wherein a V50 value for ballistic performance testing with a .44 Magnum Speer bullet is greater than 500 m/s as measured according to MIL-STD 662F, and a V50 value for ballistic performance testing with 9 mm or .357 Magnum Remington bullets is greater than 430 m/s as measured according to MIL-STD 662F.
