The relationships between strain and stress of several kinds of high strength fibers, such as Kevlar, Twaron and Dyneema were obtained, and the dependence of mechanical properties of fibers on the strain rate was gotten and explained from the microstructures and deformation mechanism of fibers. Then, the damage and failures of plates with the reinforcement of fibers under high velocity impacting were studied experimentally. Based on experimental results, a set of equations was presented to depicted the deceleration of penetrator. The dynamic response of fiber cluster and sandwich were simulated successfully with a new algorithm and code, which was developped by our group. The coupling effect of stress wave and thermal conduction could be considered with acceptable accuracy and CPU time.
