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.
