Impact Fracture Properties of Amorphous Metallic Fiber Reinforced Cementitious Composite by Fiber Length

섬유길이에 따른 비정질 강섬유 보강 시멘트 복합체의 충격파괴특성

In this study, flexural strength and impact resistance were evaluated to investigate the fiber length effect of amorphous metallic fiber. As a result, in the case of 30AFRCC, cutoff behavior due to excellent bonding performance by large specific surface area has greatly influence on the flexural and impact resistance performance. In the case of 15AFRCC, the bonding efficiency is relatively low, because the specific surface area is smaller than that of 30AFRCC and the number of fiber is large, so the effect of improving the flexural and impact resistance performance is smaller than that of 30AFRCC.
