Abstract
The preparation of new homogeneous and heterogeneous solid propellant formulations based on the new interesting high-energy dense oxidizer 2,2,2-trinitroethyl-formate (TNEF) and different kinds of binders (nitrocellulose, hydroxyl-terminated polybutadiene, and glycidyl azide polymer) are reported. The prepared TNEF was characterized by Fourier-transform infrared spectroscopy and nuclear magnetic resonance. The thermal investigation using non-isothermal differential scanning calorimetry and thermogravimetric analysis showed high thermal stability. TNEF has a decomposition temperature of similar to 210 degrees C. The high density of TNEF (1.81 g/cm(3) at 298 K) gives the propellant high loading density in the rocket motor. The Kissinger model-free method was used to determine the kinetic parameters of the studied samples. It was concluded that the new propellant formulations are a safe manufacturing process and have green (chlorine-free) gaseous products and higher activation energy than the common traditional formulations.
