A Study of Catalyzing Thermal Decomposition and Combustion of AP/HTPB Propellant with Nano Cu/CNTs

The nano Cu/CNTs composite catalyst were prepared by liquid reductive deposition method and using the carbon nanotubes as the carrier, its microstructure and composition of nano Cu/ CNTs were characterized by SEM, XRD and XPS. The catalytic performance of nano Cu/CNTs in the ther?mal decomposition and combustion of AP/HI PB propellant was investigated. The result shows that Cu/CNTs can remarkably decrease the high temperature decomposition peaks, evidently increase the aooarent decomposition heat and improve the burning rate and decrease the pressure exponent for AP/ Hl PB propellant effectively. The catalytic mechanism of nano Cu/CNTs composite on the thermal de?composition and combustion of AP/ Hl PB propellant was tentatively explored.
