Research on the Thermal Decomposition of NEPE Propellant Containing CL-20 by Situ/RSFT-IR

The thermal decomposition of NEPE propellant containing CL-20 was researched with the fast thermolysis reaction cell(gas reaction cell) in situ in conjunction with rapid scan Fourier transform infrared spectroscopy(fast thermolysis/RSFT-IR)and the solid reaction cell in situ in conjunction with rapid scan Fourier transform infrared spectroscopy(the solid reaction cell in situ /RSFT-IR).The gas product of thermal decomposition were obtained.The results show that:(1) the temperature of the volatilization and decomposition of NG increase by interaction of components and the temperature of decomposition of PEG decreases;(2) the thermal decomposition of CL-20, decompositing from solid phase directly,is different from that of RDX or HMX which melt before decomposition;(3) addition of AP shortens the process of decomposition and increase the heat release rate.
