Characterization of the dynamic behavior of yarns for the modeling of ballistic fabrics

International audience; The use of fabrics as part of ballistic protections is widely spread since 70’s. The development of these new ballistic solutions needs numerical simulations, in order to predict the performance of the ballistic protection and the potential secondary effect. The performances and the induced mechanisms in ballistic fabrics during an impact depend on the weaving parameters and also on inner parameters of yarns used in these structures. Thus, knowing the dynamic behavior of yarn is essential to determined the ballistic behavior of fabrics during an impact. For this purpose, we use four experimental setups in order to reveal dynamic parameters of ballistic yarn during high speed mechanical stress.
