High strength polymer fibers such as poly(p-phenylene terephalamide) (PPTA) are used for ballistic body armors. Additionally, a co-polymer aramid fiber containing 5-amino-2-(p-aminophenyl)-benzimidazole is also being considered as reinforcement for ballistic body armor. During ballistic impact, fibers in soft body armor are loaded in tension at fast deformation rates (typically > 1000 s-1). Compared to PPTA fibers which have been well studied, statistical characteristics of tensile properties of co-polymer aramid fibers are rarely reported. Furthermore, most of the measured fiber tensile properties which have been subjected to statistical analysis were obtained under quasi-static loading condition, many orders of magnitude loading rate lower than ballistic impact. We measure fiber tensile properties of aramid and co-polymer aramid under high rate loading conditions and compare the statistical characteristics of their respective tensile properties.
