摘要

The study was based on the behavior of the fabricated composite that comprise of aluminium and a thin layer of epoxy/aerogel and coated with epoxy/different types of silica aerogel subjected to flame fire using a standard ISO2685 propane-air burner. The aim of this study is to fabricate a new, user friendly composite and to evaluate the behaviour of the composites in a pool fire by determining the penetration time of silica aerogels used. The composites were developed to resist a fire penetration based on the standard of temperature and heat flux for at least 15 minutes for fireproof and 5 minutes for fire resistance. The developed samples are one weight percent of aerogel in the mixture of resin/hardener and were mixed using mechanical mixer and sonicator. The results indicate that composite of GEA^(TM) 0.125 silica aerogel resists higher flame than the other types of aerogel composites examined, where it was 5.56% and 10.39% more fire resistance than Enova® IC3100 and Hamzel® respectively. The study reveals that the developed composites possess the required properties to be used.
