Abstract
Abstract Based on the combustion experiment of combustion characteristics of air-supported membrane materials the fire dynamic phenomenon at different heights was studied, and the combustion critical temperature of the membrane materials was obtained, shrinkage, tension and thinning appeared on the surface of the membrane materials after the material was heated. When the temperature reached the critical temperature, the membrane materials began burning, appearing a hole with a cloud of thick black smoke. In the course of the experiment droplet phenomenon didn’t appear. Temperature data was collected by using the data collecting system Agilent 34970A.Results show that critical temperature of the air-supported membrane material when the material begin pyrolysis and burn is about 365.5 to 437.6.
