Abstract

Light-weight fire barrier materials for aircraft thermal/acoustical insulation blankets were investigated. The burn-through test on blankets inserted with these fire-blocking materials was performed using a small-scale kerosene burner apparatus. The burner system generated a turbulent flame at 1000degrees-1100degreesC and a front heat-flux at 160-180 kW/m(2). The rear or back-side heat flux of blankets and their corresponding burn-through time were monitored by a computerized data acquisition system. The blankets with ceramic or polymeric fire barrier materials provided a significantly additional burn-through time compared with the regular blankets. Blanket samples inserted with an alumino-silicate-based ceramic layer were not burned-through after 6 min. For fire resistant polymeric-based materials, the burn-through time varied from 2 to 6 min. The burn-through resistance was correlated with the stable structure Of SiO2 at high temperature for the ceramic sheets and with the formation of a char layer for polymeric layers.
