Abstract

Fabric construction affects the friction between yarns, which is a very important parameter on energy absorption and propagation. This study reports the physical properties dependent on the weaving density and STF (shear thickening fluid) impregnated aramid fabrics. To improve the frictional force between yarns, STF was applied on Kevlar woven fabrics. STF/Kevlar composite was composed of Kevlar woven fabrics impregnated with fumed silica dispersed in poly-ethylene glycol. The results demonstrated that the yarn pull-out force of neat Kevlar fabrics increased linearly as the fabric count increased. In the case regarding STF impregnated Kevlar fabrics, the pull-out force increased exponentially as the fabric count increased. Considering the ballistic performance of the fabric is related to the pull-out force of yarns in the fabric, the STF/Kevlar composite with high density woven fabrics can be a decent material for bullet-proof equipment.
