Abstract
In this research, evaluation on of textile mechanical properties was performed with using of fiber pull-out method. that used for detection of their internal intraction with concern of fiber role. One of main hypothesis in this research, using of textile as a composite that consist of filaments. In this research, textiles was used in two types, pure and impregnated to shear thickening fluid. This experiments was performed in 50,250 and 500 mm.min-1 rates and with transverse force tensile for the effect of velocity on coefficient of friction. Results show that the present of shear thickening fluid cause to significantly increasing of friction between fibers and filaments. Therefore fibers conflict together effectively and suppressed their mobility and movements. Thus neccesery energy was increased for pull-out of fibers.
