초록

본 연구에서는 기존 구조물의 방호 방폭에 대한 보강 방법으로서 프리캐스트 패널의 단층구성 재료에 경량성, 고강도, 내화성능 등을 향상시켜 단층 각각의 개별적인 특수성능과 복합적인 패널 구성물로서 방호 방폭 성능을 극대화 할 수 있는 복합섬유 패널을 제작하기 위해, 아라미드섬유(Aramid Fiber, 이하 AF)와 폴리에스터섬유(Polyester Fiber, 이하 PF)로 혼합된 내피와 외피의 기초물성을 평가하였다. 또한, 내화성능이 우수하고 경량인 Nano size의 복합소재를 이용한 충전재의 압축강도, 휨강도, 인장강도를 평가하여 복합섬유패널의 성능에 대한 기초 연구를 수행하였다.

In order to develop composite fiber panels that can maximize the protection and blast resistance of the existing structures by improving lightweight, high-strength and fireproof performances of the single layer material of precast panels, the basic properties of the inner and outer covers that are mixed with aramid fibers (AF) and polyester fibers (PF) were evaluated in this study. Also, a basic study was performed on the performance of composite fiber panels by testing Nano-sized composite materials that are lightweight and excellent in fire resistance for their compressive strength, bending strength and tensile strength.
