Abstract
The present paper deals with the simulation of impact of ogival tip projectile on multi-layered plain woven high modulus polypropylene (HMPP) fabric impregnated with shear-thickening fluids (STFs) composed of fumed silica nanoparticles suspended in polyethylene glycol (PEG) using finite element analysis as implemented in LS-DYNA. The effect of STF impregnation on fabric are taken into account as the friction between the yarns and their crossovers and the friction between projectile and fabric during impact. The numeric results confirmed the contribution of frictional properties induced by STF impregnation in restriction of the yarns within the fabric and consequently improving the ballistic properties of woven structures.
