Abstract

This study tested the wood used in building interiors; each type had various incident heat fluxes based on their thickness. The combustion characteristics measured were effective heat of combustion, heat release rate peak and arrival time, maximum average rate of heat emission, and piloted ignition temperature. The wood specimens used in the experiment were 4.8 to 18 mm thick. 25, 35, 50, and 60 kW/㎡ were applied to the incident heat flux that the wood specimens were exposed to. The wood specimens tested were two types of medium-density fiberboard (each with a different density), treated red pine, particle board, and plywood. A comprehensive comparison of different fire characteristics was conducted to analyze the fire patterns corresponding to each type of wood in this way, the risk of fire was studied. The risk of fire was particularly high for particle board. The results of quantifying the fire characteristics of the types of wood studied could function as important input data with which to calculate the fire load of composite combustibles.

본 연구에서는 건축내장용 합판류 목재를 대상으로 목재의 두께별 다양한 입사열유속에 따른 연소특성 측정 실험을 수행하였으며, 측정한 연소특성은 EHC, HRR peak 및 도달시간, MARHE, 인화온도이다. 실험에 사용된 목재 시편은 4.8~18 mm 두께, 목재 시편에 유입되는 입사열유속은 25, 35, 50 및 60 kW/㎡을 적용하였으며, 목재 시편의 종류는 MDF 2종, 파티클 보드, 일반 합판이다. 종합적인 비교를 통하여 연소특성별 각각의 목재에 해당하는 화재패턴을 분석하여 화재에 대한 위험성을 검토하였다. 파티클 보드의 경우 화재 위험성이 높게 나타났으며, 제시한 연소특성 정량화 결과는 복합 가연물의 화재하중 산정에 중요한 입력 요소로 기여될 수 있다.
