AbstractIn the velocity range from 1450 m/s to 2100 m/s, the penetrators prepared by Zr-based metallic glass composites with tungsten fiber of 80% volume fraction and 0.3 mm diameter were used to perforate 30CrMnMo steel plates. Results are as follows. (i) The penetration efficiency is influenced by properties and structure of the material, which is helpful to design the rod penetrator of composite material. (ii) For the different structures of the penetrator, curves of penetration depth with velocity are different. The curves of the penetrator with two segments and three segments structures are convex, and at 1750 similar to 1800 m/s and 1850 m/s they arrive to the maximums which are both 1.7L. For the monolithic penetrator, however, the curve is asymptote, and above 1850 m/s the penetration depth approaches to the hydrodynamic limit which is L.(rho(p)/rho(t))(1/2), about 1.5 L. (iii) According to the dynamic damage characteristics of the unidirectional fiber reinforced composite materials, the characteristics of dynamic crack propagation and erosion velocity of impact, the optimal segmentation is defined, and the problem in (ii) is solved, providing a reference for structure design of segment penetrators.
