철도차량 내장판용 페놀수지의 화재특성 연구

초록

The time to ignition, heat release rate characteristics and carbon monoxide yield of fiber reinforced and honeycomb type phenol resin were investigated with cone calorimeter. Heat flux of 35 kW and 50 kW was used. Thermal gravimetric analysis(TGA) was used to monitor the degree of thermal decomposition for the phenolic resin. according to the cone calorimeter data, the time to ignition and heat release rate was faster and higher as the external heat flux increase. But, CO yield was not shown that tendency. under the same heat flux, the time to ignition of fiber reinforced phenolic resin was faster than that of sandwich type.
