Analysis of Failure Reduction Properties Cementitious Composites with Reinforced Fiber by Impact of High Velocity Projectile

비상체의 고속 충격을 받는 시멘트복합체의 혼입 단섬유에 따른 파괴저감특성 분석

Flexural stress and fracture energy of fiber reinforced cementitious composites is increased by bridge effect of reinforced fiber, scabbing failure is restrained. Shape, properties of fiber were SF(steel fiber), PA(polyamide), NY(nylon) have effects on flexural stress and fracture energy, impact resistance improve of fiber reinforced cementitious composites. In this study, local failure properties by impact of high velocity projectile was analyzed by mixing 3 types of fiber which have different shape and properties respectively.
