Abstract
The thermal behaviors and mechanism of nano-based fuel air explosive (FAE) were investigated by using DSC measurements in different situations and DSC/TG–FTIR–MS coupled technique. The thermal decomposition process of FAE under non-oxidizing environment was analyzed and described. The decomposition of FAE takes place in a multistage complex process. The first process is assigned to volatilization process of the volatile components. With an increase in temperature, isopropyl nitrate starts to break up into alkene and secondary alcohol. In the temperature range of 350–500 °C, the dominant volatile products are hydrocarbon fragments, CO2 and H2O. At the same time, the full formulation of FAE and formulation without nano-Al powder were studied and compared. The thermal decomposition of other components in FAE is significantly promoted by nano-Al powder.
