Ballistic tests on packs made of stratified aramid fabrics LFT SB1

Abstract

Ballistic experiments are fundamental for body armor new products and help to identify key factors influencing the damage processes of sophisticated materials these armors are made of. Tests made on packs made of LFT SB1 according to Ballistic Resistance of Body Armor NIJ Standard-0101.06-2008 gave good results for the packs made of 24 layers of this fabric and the backface signature (BFS - the depth of the deformation generated in the support material - ballistic clay) was measured. The average value of 23.11 mm recommends this system for protection level of II and IIA, according to the above-mentioned standard. Macro photography investigations pointed out the penetration process in both slim pack (with total penetration) and thick packs (with partial penetration).
