Abstract

Due to the enhanced energy absorption characteristics, the steel fiber-reinforced concrete (SFPC) structures gains more and more attention in the civilian and military ballistic protection structures when comparing with the plain concrete (PC) ones. By comparison on the penetration depth, the crater volume on impact face of the target and the debris cloud topography, the resistance of PC and SFPC slabs against projectiles impacting was investigated experimentally in a two-stage light-gas gun. In order to more widespread understand the effect of steel fibers against projectiles impacting, five different types of concrete slabs were done in the range of unconfined compressive strength from ordinary to high. Through the analysis of the test results it was found that the incorporation of steel fibers in the concrete reduced the crater diameter and restrained the initiation and propagation of cracking, but did not have a significant effect on the penetration depth.
