Abstract: A new structure of post-composited rod is designed to improve the penetration ability of rod penetrator. The comparison experiment of post-composited rod and homogeneous rod with the same overall structure invertically penetrating a semi-infinite steel target is conducted. The result indicates that the penetration ability of post-composited rod is superior to that of homogeneous rod. The maximum penetration depth of post-composited rod is 25% more than that of homogeneous rod. The reason of the result is analyzed by the numerical simulation and verified by experimental result. The further simulation of post-composited rod with four different configurations in penetrating a semi-infinite steel target at impact velocity from 1 000 m/s to 1 600 m/s is carried out. The corresponding relationship between the penetration efficiency of post-composited rod with different configurations and the impact velocity is obtained.
