Abstract

The bond properties between polypropylene fiber reinforced cement composites and structural synthetic fiber have been investigated. in this paper. Three levels of polypropylene fibers volume fraction were used, 0.10%, 0.15%, and 0.20% in a series of Dog-bone pull out tests. The bond strength between structural synthetic fiber and polypropylene fiber reinforced cement composites increases with the volume fraction of polypropylene fiber, but the bond strength decreases above the amount of 0.20% by volume of polypropylene fiber reinforced cement composites. Also, the addition of polypropylene fiber a significant improved the interface toughness and the frictional resistance, The microstructure of structural synthetic fiber surface was investigated after the pullout test. The scratched of structural synthetic fiber increased with the polypropylene fiber volume fraction.

폴리프로필렌섬유보강 시멘트 복합재료와 구조용 합성섬유의 부착특성을 평가하였다. 폴리프로필렌섬유는 0.10%, 0.15% 및 0.20%의 체적비로 적용하여 dog-bone 시험을 실시하였다. 구조용 합성섬유와 폴리프로필렌섬유보강 시멘트 복합재료 사이의 부착강도는 폴리프로필렌섬유의 혼입률이 증가할수록 증가하였으나 0.20% 이상이 되면 감소하였다. 또한 폴리프로필렌섬유의 첨가는 계면인성과 마찰저항을 증가시킨다. 인발시험 후 구조용 합성섬유 표면의 미소구조 분석은 폴리프로필렌섬유의 혼입률이 증가할수록 긁힘 현상이 증가하였다.
