Concrete subjected to dynamic loading shows local failure and it can be suppressed by improvement of flexural toughness with reinforced of fiber. Since bonding properties of fiber with matrix, specific surface area and numbers of fiber are different by fiber reinforcement type, mechanical properties of fiber reinforced concrete and improvement of impact resistance performance need to be considered. In this study, improvement mechanical properties by dynamic lodaing have been evaluated according to SF, PA fiber.
