Abstract:

To illustrate the impact resistance ability of fabrics under ballistic impact, we used the finite element software package ABAQUS to investigate the impact resistance properties of one kind of typical 2-D aramid fiber fabric. The velocity curve, energy curve, propagation of stress wave and process of ballistic impact were plotted and analyzed and the impact resistance performances and behaviors of this type of fabric were revealed. Under the ballistic impact which can’t puncture the 2-D fabric, the impact process can be divided into 2 stages, and mutual transformation between internal energy and kinetic energy occurs during the impact process. This work of study provides an effective prediction method for designing impact protective fabrics and impact protective analysis of other materials.
