N2 - Various energetic formulations that rely on the mixing together of plasticized cellulosic polymers compounded together with various solvents and myriad energetic particles exhibit gel-like characteristics. Gelation during processing retards or prevents the distributive and dispersive mixing of the ingredients and the shaping of the formulation. Incorporation of various types of nanoparticles into such formulations is expected to accelerate the formation of such gels during processing and increase their moduli. Here it is demonstrated that the effective distributive and dispersive mixing of the ingredients of an energetic simulant based on a nanoaluminized cellulose acetate butyrate formulation, which cannot be achieved with conventional technologies including roll-milling, can be achieved upon the use of the twin screw extrusion technology starting from a molding powder, in conjunction with a judicious selection of operating conditions and extrusion geometries.
