Effect of Strike-face Material Strength on Ballistic Performance of Multi-ply Soft Armor

ZHERUI GUO, J.Q. ZHENG, WEINONG CHEN

Abstract


In this study, the impact-face material of a multi-ply soft armor system was varied to different ratios and tested for the effects on the ballistic performance. While it is known that the first few layers of multi-ply soft armor material typically fail inelastically near the system ballistic limit and can be replaced with a “sacrificial” material with other more desirable properties, the extent to which the highperformance fabric can be replaced has yet to be quantified. Materials of different shear strengths, namely stainless steel mesh, Makrolon®, and cotton were used as replacement material for 840d Twaron®, and the hybrid panels were impacted by O1 tool steel RCC projectiles fired using a single stage smooth-bore gas gun.
