Impact Resistant Flax Fiber Fabrics Using Shear Thickening Fluid

Shear thickening fluids (STFs) have been shown to improve the effectiveness of fabrics used in soft body armor applications. They are increase puncture and ballistic impact resistance Kevlar® fabrics. However, effect using STFs with natural such as flax appears never studied. Similarly, hybridization different fabric types impregnated STF has also only undergone limited study. The rheology at varying concentrations nanosilica dispersed polyethylene glycol (PEG) was studied temperatures. It found that behave a non-Newtonian fluid response changes shear rate. In this study on impregnating 30%, 50%, 70% w/w PEG investigated. both treated hybrids significantly can be controlled by concentration. hybrid samples when concentration least 50%. showed either decrease specific energy absorption per layer for lower concentration, or very small
