Abstract: A ballistic impact model was established for textile fabric reinforced composites by using an ABAQUS software to analyze the residual velocity, variation of acceleration and energy loss when a bullet passed through the composites, in which the initial conditions for the incident bullet was set in accordance with the actual one. The results indicated that both the theoretic and experiment values for the residual velocity kept a linear relationship with its incident velocity. The higher the incident velocity, the greater the slope of plot of bullet velocity vs. time at the initial stage of incident bullet, and the greater was the absolute value of acceleration at peak. The calculated values obtained from the simulation of energy loss for the ballistic impact was in good agreement with experimental ones.
