Abstract
In this study, two Heracron? woven fabrics, HT840-1 and HT840-2, were fabricated with different multifilament fibers, and their resistance to ballistic impact was investigated. For the same weight and number of plies, the HT840-2 fabric showed improved ballistic properties, compared with HT840-1; this result is contrary to the fiber and fabric properties. With the exception of the yarn’s physical properties, this behavior can be explained in terms of the number of multifilaments, which strongly influenced the ballistic mechanism, i.e., a greater number of multifilament fibers facilitates energy dissipation from a high-speed ballistic projectile. In summary, establishing this optimal number of multifilaments is the key to optimizing the ballistic properties of any given fabric.
Highlights
Aramid poly (p-phenylene terephthalamide) or PPTA consists of relatively rigid polymer chains with linked benzene rings and amide bonds
The results given suggest that the lower ballistic resistance of HT840-1 may be explained by an insufficient number of multifilament fibers
Two Heracron® woven fabrics with different numbers of multifilament fibers were assessed for their resistance to ballistic impact
Summary
Aramid poly (p-phenylene terephthalamide) or PPTA consists of relatively rigid polymer chains with linked benzene rings and amide bonds This structure affords aramid fibers high tenacity, high modulus, and toughness [1,2,3]. The ability of a woven fabric to protect against bullets depends primarily on the mechanical properties of the yarn, such as the tenacity, tensile modulus, and toughness. The energy absorption mechanism of soft armor depends on several additional factors, such as the weave pattern, the number of fabric plies, and the weave density. Our research group previously compared the effect of the weaving density of aramid fabrics on their resistance to ballistic impacts. This study provides fundamental information on how the number of multifilaments regulates fabric properties and the ballistic behavior of aramid woven fabrics
