Experimental study on the influence of weaving parameters on the ballistic performances of 3D fabrics
Résumé
This paper deals with the study of weaving parameters and their influence on the ballistic performances of 3D fabrics. The goal is to better understand how such fabrics behave when they undertake impact loadings and to find some ways to improve their capacity to absorb the kinetic energy of projectiles. The study is focused on the layer-to-layer interlocks. As varying parameters, we study the material (aramid and polyethylene), the yarn density, the number of inner layer of the structure and the total areal density of the samples. Ballistic tests with 5 mm steel balls at different velocities are performed. Residual velocities after perforation are evaluated by high speed camera or X-ray pictures. Analysis of the experimental results and perspectives on future works are then given.
