Abstract:

Based on the understanding of the response of flexible materials upon ballistic impact, by finite element analysis and ballistic test, this paper reviews the working mechanisms of projectile-material and yarn-yarn friction in ballistic protection, investigates the direct and indirect influence of friction on projectile energy absorption, and summarizes the common approaches for frictional increase. It gas been found that increasing the projectile-material friction leads to an increase in material kinetic and strainenergy absorption, and increasing yarn-yarn friction avoids yarn slippate and enlarges the energy absorption area; it has also been claimed that, although an increase in friction could be obtained using fiber-surface-modification -based technology, treated fabric is difficult to massively profuce; and incorporation of leno structure into plain weave increases the wraping angle of the weft yarns, leading to an improvement on yarn gripping. In addition, structure-modification-based-technology could be achieved on the power loom, solving the problems of mass production and overhigh labor cost.
