The paper presents results of experimental research and numerical analysis (AnsysAutodyn v13 program) of penetration of 10 and 16 layers of the Twaron T750 aramid fabricwith the 9 mm Parabellum projectile. As a boundary condition in the experiment and in thenumerical simulations it was assumed that all the four edges of the fabric were fixed. In thenumerical simulations the sample of 50x50 mm dimensions and the impact velocitiesV_i=448 m/s for 16 layers of the fabric and V_i =454 m/s for 10 layers of the fabric wereadopted. In the paper the results of the numerical simulations for three materialconfigurations with the same friction coefficients and for different values of yarn-yarnfriction in case of one material configuration are presented. Residual velocity of thepenetrator for the highest friction coefficient μ_s=1 decreased of 13.1% in comparison tosimulation with no friction (μ_s=0).
