자동차 내장재의 연소 특성에 관한 연구

We have carried out the test using the cone calorimeter and the smoke density chamber to evaluate the characteristics of the combustion for the car interior materials passed horizontal burning test. We have analysed many parameters related to fire hazard. These parameters are the ignition time, the heat release rate, the maximum average rate of heat emission, the flashover propensity and specific optical density. There was a significant difference in HRR and optical smoke density. The HRR was 185~446㎾/㎡ and optical smoke density was 119~1207. Only horizontal burning test was performed to evaluate the fire hazard for the car interior materials.
