Preparation and characterization of CL-20 based composites by compressed air spray evaporation

Abstract

Ultrafine CL-20 particles and three CL-20-based composites were prepared by a compressed air spray evaporation method. All samples were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), differential scanning calorimetry (DSC) and mechanical sensitivity instruments. The results indicated that the thermal stabilities of the CL-20-based composites are better than that of ultrafine CL-20, and that the mechanical sensitivities of ultrafine CL-20 is lower than those of CL-20-based composites. The thermal stability and safety properties of CL-20/Estane 5703 are better than the other samples.
