Influence of Reinforced Fiber on Local Failure of the Concrete subjected to Impact of High-Velocity Projectile

고속 비상체 충돌에 의한 콘크리트의 국부파괴에 미치는 혼입 섬유의 영향

The purpose of this study in to evaluate relationship between mechanical properties of materials and fiber type by reinforced fiber with high-velocity impact fracture behavior of fiber reinforced concrete. As a result, for fracture behavior by high-velocity impact, it is considered that impact fracture behavior is not affected by static mechanical properties directly but affected by fiber type and density of the number of fiber. It is necessary to consider type, shape, mechanical properties and the number of fiber with flexural and tensile performance for the evaluation on impact resistance performance of fiber reinforced concrete.
