Study on the Arrangement of Fabric Materials for Multi-Layer Soft Body Armor Based on their Mechanical Properties
The arrangement of protective material of bullet proof vest is important for face and back strike when all backing materials are hybrid. In this paper, three hybrid protective materials, as UD aramid fabric, Polyethylene (PE) and laminated woven aramid fabric (Argus) were used in this work. The bullet proof vest made of these combinations of materials to wear flexible and comfortable. It was found that the mechanical properties, as work of rupture of material, Young's modulus, bursting strength and penetration stroke at bursting, give trend to arrange the face and back strike for bullet proof vest, the increasing of work of rupture enables energyabsorbing mechanisms and the materials with high work of rupture enable to absorb energy to predict the arrangement of the layers before shooting.
