Abstract

본 연구에서는 건축외장재로 많이 사용되고 있는 알루미늄복합패널의 일반재와 난연재에 대한 화재성능 비교분석에 관해 연구하였다. 실험방법은 중소형 실험장치 중 콘칼로리미터 실험과 SBI(Single Burning Item)을 적용하여 분석하였다. 그 결과 콘칼로리미터 실험에서 최대 열방출률이 일반 알루미늄복합패널은 <TEX>$1,293kW/m^2$</TEX>(<TEX>$75kW/m^2$</TEX>), 난연 알루미늄복합패널은 <TEX>$70kW/m^2$</TEX>(<TEX>$75kW/m^2$</TEX>)가 측정되었다. SBI 실험에서 화재확산지수가 일반 알루미늄복합패널은 약 743W/s이고 난연 알루미늄복합패널은 약 97 W/s의 값이 측정되었다. 이는 일반 알루미늄복합패널의 경우 건축물 내장재의 성능기준에서 난연기준에도 훨씬 못 미치고, 플래쉬 오버(Flash over) 발생 가능성을 나타내었다. 따라서 이러한 알루미늄복합패널의 화재 위험성을 평가하여 외장재로서 사용 시 갖춰야 할 조건에 대한 기준마련이 시급히 요구된다. In this research, aluminum composite panels of the general materials and fire retardant materials as building claddings make researches about fire performance comparison analysis. Test methods of the small and medium cone calorimeter experiments and SBI (Single Burning Item) experiments was applied to the determination. As a result, in the experiments peak heat release rate cone calorimeter the general aluminum composite panel <TEX>$1,293kW/m^2$</TEX> (<TEX>$75kW/m^2$</TEX>), flame-retardant aluminum composite panel <TEX>$70kW/m^2$</TEX> (<TEX>$75kW/m^2$</TEX>) was measured. In the SBI experiments fire growth rate the general fire aluminum composite panel is approximately 743 W/s and the flame-retardant aluminum composite panel is approximately 97 W/s of the value were measured. Thus, a standards enactment are urgently required in this case it is used as building claddings of the aluminum composite panel by fire risk assessment.
