CEMENTITIOUS COMPOSITE WITH STRUCTURAL SYNTHETIC FIBER AND METHOD FOR MAKING THE SAME
The present invention relates to a cementitious composite with structural synthetic fiber which applies an organic nano-material and an inorganic nano-material to conventional structural synthetic fiber as a reinforcing material to improve material performance, and improves attachment performance with respect to a cement matrix by a physical surface treatment on a longitudinal surface of smooth cylindrical fiber produced by a conventional melt-spinning technique in order to improve drawing resistance of the fiber, and to a manufacturing method thereof. According to the present invention, a primary physical surface treatment and a secondary twisting process are performed to improve attachment performance with respect to the cement matrix in comparison to conventional structural synthetic fiber. The organic nano-material and the inorganic nano-material are used as reinforcing materials of the fiber to improve performance of a polymer matrix itself, wherein the polymer matrix is a main material of the structural synthetic fiber. Accordingly, the performance of the structural synthetic fiber as a reinforcing material is improved by 80-140% in comparison to structural synthetic fiber made by a conventional technique.
본 발명은 기존의 구조용 합성섬유에 유기 및 무기질의 나노재료를 보강재로 적용하여 재료적인 성능향상을 도모하고, 또한 기존의 용융방사기법을 통해 생산된 매끈한 원형의 섬유의 종방향 표면에 물리적인 표면처리를 통해 시멘트 매트릭스와의 부착성능을 향상시켜 인발저항성이 향상된 시멘트계 복합체 구조용 합성섬유 및 그 제조방법에 관한 것이다. 상기와 같은 본 발명에 따르면, 1차적인 물리적 표면처리와 2차적인 꼬임(twist) 가공을 함으로써 종래의 구조용 합성섬유에 비해 시멘트 매트릭스와의 부착성능을 향상시키며, 유기 및 무기질의 나노재료를 섬유의 보강재로 사용함으로써 구조용 합성섬유의 주요 재료인 폴리머 매트릭스 자체의 성능을 향상시켰다. 이를 통해 구조용 합성섬유의 구조 보강재로서 성능을 종래 선행기술들로 만들어진 합성섬유 보강재보다 80~140% 향상시키는 효과가 있다.
