Abstract:

In order to study the ignition ability of metal- based electrothermal film, cotton quilt and towel are selected as combustible cover materials. The temperature changes of various positions of the cover material were studied experimentally, under the conditions of different film power, covering thickness and moisture content. A model was established. The temperature of the place electrothermal film connecting the cover at different ambient temperatures were calculated by the model.The results of this paper can provide some reference data for fire prevention and fire investigation of electrothermal film fire. 

Key words:  metal- based electrothermal film, ignition ability, flammable cover, model calculation
