The ballistic impact characteristics of Kevlar® woven fabrics impregnated with a colloidal shear thickening fluid

摘要: This study reports the ballistic penetration performance of a composite material composed woven Kevlar® fabric impregnated with colloidal shear thickening fluid (silica particles (450 nm) dispersed in ethylene glycol). The Kevlar yields flexible, yet resistant material. Fragment simulation projectile (FSP) measurements at ∼244 m/s have been performed to demonstrate efficacy novel results significant enhancement resistance due addition fabric, without any loss flexibility. Furthermore, under these test conditions, targets perform equivalently neat equal areal density, while offering significantly less thickness and more is shown be associated response, possible mechanisms fabric-fluid interaction during impact are identified.
