Abstract In this work, ballistic resistance of single and 2-layers aramid fabric structures with different weaving architectures and orientations were investigated via the impact tests carried out using a gas gun setup. To analyse the influence of each structural factors and their significance, a statistical study was performed using Taguchi method with a L9 matrix, which indicated the optimum structural arrangements for the 2-layer fabrics. The reduction of the velocity, the consequently absorbed energy, and the post-mortem failure modes were analysed to understand the ballistic resistance of the fabric structures studied. To investigate the damage mechanisms of different weaving structures, mesoscale Finite Element models were developed to observe the resultant velocity of the projectile, the deformation of the woven yarns, as well as the evolution of the energy components. The final model was then constructed in resembling the optimum structural arrangement derived from the Taguchi statistical study, which revealed the significance of yarn-yarn and yarn-projectile friction properties towards the ballistic resistance of the fabrics.
