Influence of architecture and orientation in 2-layers fabric structures

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, mesosca..
