CEMENTITIOUS COMPOSITE WITH STRUCTURAL SYNTHETIC FIBER AND METHOD FOR MAKING THE SAME
The present invention relates to synthetic fibers for a cement-based composite structure and a production method therefor, wherein the synthetic fibers promote the improvement of material performance by applying organic and inorganic nanomaterials as reinforcements to conventional synthetic fibers for a structure and have improved pullout resistance by improving adhesive performance with respect to a cement matrix through a physical surface treatment on the longitudinal surface of smooth, circular fibers produced using a conventional melt-spinning technique. As such, the present invention improves adhesive performance with respect to a cement matrix in comparison with conventional synthetic fibers for a structure by means of primary physical surface treating and secondary twisting and improves the performance of a polymer matrix itself, which is a main component of the synthetic fibers for a structure, by using organic and inorganic nanomaterials as reinforcements for the fibers. As a result, the present invention has the effect of improving the performance of the structure reinforcements of the synthetic fibers for a structure by 80-140% in comparison with synthetic fiber reinforcements produced using prior art.
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.
