The aim of this study is to investigate the impact resistant performance of ductile fiber reinforced cementitious composites (DFRCCs) containing 1.5 % volume fraction of polyvinyl alcohol and steel fibers subjected to high velocity impact of steel projectile (the diameter of 19.05 mm and the mass of 28.13 g). To investigate the impact resistant performance of DFRCCs, gunpowder impact facility was used for impact tests, and the impact velocity was from about 450 to 750 m/s. The impact tests were also performed on non-fiber reinforced cementitious composite (Plain) specimens for comparison. The specimens were damaged in various failure modes, which are penetration, scabbing, and perforation. DFRCC specimens have superior capacity on the scabbing limit, and slightly bulged in the back side under the impact velocity of 700 m/s. The fibers play an important role in controlling the local damage of DFRCCs. In perforating, the debris of DFRCCs slightly scattered around a position of the back side in the cross section of the specimen.
