Abstract

In this paper, finite element model of woven fabric target has been investigated which is impacted by a cylindrical projectile. Fabrics are impregnated with Shear Thickening Fluid (STF). The effects of the (STF) have been considered as frictional effect. The STF has been made (Nano Silica and Polyethylene Glycol (PEG)) and then diluted by ethanol proportion of 3:1. Yarn pulling out test from inside of fabric is performed to estimate the pulling out force and the friction coefficient. The speed of pulling out was 500 mm/min and the samples were placed vertically in tensile device. The results of yarn pulled out indicated that the fabric impregnated in STF needs more force in order to gets out of fabric. Friction coefficient of a regular fabric is 0.26 and in a fabric impregnated by STF is 1.5. Friction coefficients of tow fabric types of raw fabric and fabric with STF are entered in ANSYS software along with mechanical characteristic of a yarn. Ballistic range velocity was extracted for samples in software and was compared with experience results.
