Abstract

The membrane structure provides high satisfaction with lightweight, improved workability, reduced cost, and a free shape. Thus, its applications expanding. On the other hand, in an architectural membrane that is vulnerable to fire, the development of various architectural membranes with flame resistance is in demand. Therefore, this study applied basalt woven fabric safety for flame resistance, excellent heat insulation and thermal properties on an architectural membrane. The PTFE- coated basalt woven fabric membrane was compared with a PTFE coated glass fiber membrane by DSC/TGA, strength properties, flammability, and incombustibility properties. In addition, this study confirmed the membrane applicability of basalt woven fabric and basalt-glass hybrid woven fabric through a comparison with existing architectural membranes.

막구조 건축물은 경량의 건축용 막재를 사용하므로 자유로운 곡면표현이 가능하고 시각적인 만족도가 높아 그 사용이 점차 확대되고 있다. 하지만 건축용 막재를 구성하는 직물이 화재에 취약하므로 용도에 적합하며 보다 높은 난연성능을 가지는 불연성 막재의 개발이 요구되고 있다. 따라서 본 연구에서는 단열성, 내열성, 불연성이 우수한 현무암섬유를 건축용 막재의 직포로 적용하고 PTFE 분산 수지를 함침 코팅하여 DSC/TGA 열분석, 강도특성, 방염 및 난연특성을 평가하였다. 또한, 일반적으로 사용되는 건축용 막재 중 성능이 가장 우수한 유리섬유 직포 막재와 난연특성을 비교하였으며 평가결과 현무암섬유 직포의 건축용 막재로서의 가능성을 확인할 수 있었다.
