چکیده In this paper, yarn pull-out testing was performed to estimate the pulling-out force and the friction coefficient. Fabrics were impregnated with Shear Thickening Fluid (STF) of two types. Single fibre tensile tests were performed to determine the resistance of each fibre. The speed of pulling out was 500 mm/min and the samples were placed horizontally in a tensile device. The results indicated that the fabric impregnated in STF needed more force in order to get out of the fabric. Friction coefficients of three fabric types of raw fabric, fabric with dissolved fluid and fabric with STF were entered into an explicit dynamics finite element model along with the mechanical characteristic of a yarn. Ballistic range velocity was extracted for samples by the software and was compared with experimental results. The effects of the shear thickening fluid (STF) were considered as frictional effects.
