Abstract: The degree and pattern of damage in composite armors influenced by the shock wave were decided by comprehensive factors. Herein, a wave-absorbed layer was used to decrease the degree of damage in materials by shock wave. Meanwhile, some effective measures were adopted to improve the ballistic performance of composite armors based on decreasing the reflection and overlapping of the shock wave. The experiment results shows that the wave-absorbed layer improves the ballistic performance of composite armors remarkably.
