초록

일반적으로 유기섬유는 섬유 자체의 인장강도 및 탄성계수는 작지만, 내화성 및 내부식성이 우수하고, 콘크리트의 균열 제어 및 내충격 성능 향상에 효과적인 섬유이다. 따라서, 유기섬유는 콘크리트용 보강 섬유로서의 적용성이 매우 높은 재료이다. 본 연구에서는 폴리아미드(PA)섬유와 고강력의 폴리에스터(PET)섬유를 혼입한 하이브리드 유기섬유를 개발하였으며, 하이브리드 유기섬유를 혼입한 섬유보강 콘크리트의 휨성능 시험을 통해 하이브리드 유기섬유 보강 콘크리트의 에너지 흡수능력을 평가하고자 한다.

Organic fiber reinforced concrete is applicable to many applications for construction material. In general, organic fibers have low tensile strength and elastic modulus, but they have many advantages such as high crack resistance, impact resistance, chemical resistance, flexural behavior and corrosion resistance. In this study, hybrid organic fibers were prepared by mixing polyamide (PA) fibers and high strength polyester (PET) fibers. Then, flexural performance test of fiber reinforced concrete containing hybrid organic fiber was performed. The energy absorption capacity of the hybrid organic fiber reinforced concrete was evaluated.
