The present study was performed to prepare, characterize and evaluate the rheology of CuCr2O4 @ rGO nanocomposite. This nanocomposite was used as a new catalyst in composite solid propellants. One of the applications of catalyzed copper chromite nanocomposite with reduced graphene oxide is the rheological casting behavior of composite solid propellant slurries. The reduction of viscosity in the casting process in composite solid propulsion has been investigated. Also, complete curing of solid propellant composite with copper chromite nanocomposite with reduced graphene oxide was performed. Casting viscosity reduction parameter in composite solid propulsion containing CuCr2O4 @ rGO nanocomposite plays an important role in casting large diameter propellants in the propulsion and launch of space satellites.
Copper chromite is an almost versatile catalyst involved in many commercially important chemical processes related to defense, space, control, and environmental pollution. By investigating the mechanical properties of CuCr2O4 @ rGO nanocomposite, the effect of reduced graphene oxide on chromite copper and the complete sintering process of composite solid propellant and comparison with chromite copper catalyst was performed.
CuCr2O4 @ rGO nanocomposite was prepared by hydrothermal method and EDX, SEM, XRD and FTIR methods were used for characterization. The rheological properties of the nanocomposite were compared with both the synthesized samples and the chromite copper reference catalyst samples in the composite solid propellant. By measuring the mechanical properties of the cured samples, the test results show that all the measured parameters are within the allowable range. Also, the results of reducing the viscosity of the slurry show that the propellant slurry containing CuCr2O4 @ rGO nanocomposite has a better casting capability.
