Energetic materials production has the risk of uncontrolled explosion at high temperature which is hazardous for personnel and equipment. Flexible aerogel blanket is fireproofing and has the lowest heat transfer among the thermal insulations. In this study, aerogel blanket with 3mm thickness have been used as insulating layer within multilayer composite textiles contain clothes which are fireproof and compatible with the body. Then, its performance as heat transfer barrier have been evaluated against explosion of the energetic materials. Direct fire testing at controlled conditions and field testing under uncontrolled explosion of the energetic materials have been performed. Results showed that aerogel composites have high capability in preventing from the temperature rising and burning of persons exposed in explosion of energetic materials. When aerogel composite exposed to explosion of energetic materials, the temperature of the other side of the composite did not exceed from the pain threshold temperature (44oC). Also, the experimental testing showed the aerogel composites provide sufficient time for escape and avoid from burn injury. Flexibility and thickness of the aerogel composites are such that it is possible to prepare insulating and fireproofing clothes using them.
