In this study, the effects of friction on ballistic performance of fabrics used in armors have been investigated. Residual velocity was obtained as a criterion of ballistic performance of fabric. For this purpose, ballistic tests were performed on the Kevlar fabric and double plies of fabric were shot with hemispherical projectiles. Also a finite element model was developed using LS-DYNA software. The result of the simulation shows an acceptable agreement between the experimental and numerical analysis. Friction was introduced between Kevlar yarns and also between the projectile and the fabric. Results show that friction has an effect on decreasing projectile velocity via delaying fabric failure and therefore improve fabric ballistic performance. The simulation result may be a proof that the increased ballistic performance for shear thickening fluid impregnated Kevlar fabric is at least due to the increased friction.
