Abstract: One of the most important properties of fiber-reinforced composites is its considerably improved impact resistance compared to that of the unreinforced matrix. However, the choice of fiber type, length and shape greatly influence the composites performance. Recently, utility of hybrid fiber system has been advocated with the intent of conforming the best performance characteristics of each constituent fiber types to the composite material. It was seen from literature that the hybrid fiber composites have not yet investigated extensively, particularly studies on the dynamic properties. This paper presents the results of experimental investigation on the impact behavior of steel-polymeric hybrid fiber reinforced mortar using instrumented drop weight impact machine. It was seen that the partial replacement of polymeric fiber with steel fiber, modifies the failure mode of polymeric fiber from brittle to ductile and enhances the energy absorption capacity. However, the enhancement due to the steel fiber addition is relatively lower for impact loading as against to static loading.
