Abstract

The objective of this study is to develop an advanced stab proof material composed of shear thickening fluid (STF) and Kevlar fabric. In this study, silica/ethylene glycol suspension was prepared for the use as the STF, and it was analyzed by a rheometer, TEM and dynamic light scattering spectrophotometer. From the results, it was observed that the STF significantly showed the reversible liquid-solid transition at a certain shear rate. Also, we treated Kevlar plain fabric with the STF by 1 dip-1nip finishing method and investigated the mechanical and stab resistant properties. Through the investigation of the fumed silica/Kevlar composite fabric, we found that the STF impregnation significantly improved the stab resistance of Kevlar fabric against spike threats and so enhance the protection performance of Kevlar fabric as a stab proof material.
