The Interaction between the Components in NEPE Propellant Containing CL-20

The thermal decomposition characteristics of NEPE propellant containing CL-20(CL-20-NEPE propellant) and interaction between the components,such as NG,CL-20 and AP in NEPE propellant containing CL-20,were studied by thermogravimetry(TG).The results show that the thermal decomposition of CL-20-NEPE propellant proceeds in three stages,firstly the volatilization and decomposition of nitrate ester,secondly the decomposition of PEG and CL-20,thirdly the decomposition of AP.The decomposition of NG and PEG in binder were improved with the existence of CL-20 and AP.The improving effect of CL-20 is greater than that of AP for the decomposition of NG and PEG in binder.The decomposition temperature of AP decrease because of the decomposition product of CL-20.The interaction between Al and other ingredients is not obvious.
