Abstract
A method of formulating high energy explosives and propellants, including e steps of melting the explosive at a temperature just above its melting temperature, admixing and dissolving or plasticizing a binder, and extruding or casting the resultant solution into a useful form for further forming the resulting material into a munitions. The first step in this method includes the use of any high energy explosive material. Examples of these include hexanitrohexaazaisowurtzitane or CL-20, 1,3,3-trinitroazetidine or TNAZ, 2,4,6-trinitrotoluene or S-TNT, 1,3,5-trinitrobenzene or S-TNB, HMX, RDX, butane-trio-trinitrate or BTTN, trimethylolethane trinitrate or TMETN; triethylene glycol dinitrate or TEGDN, bis, 2,2-dinitro propyl acetal/bis 2,2 dinitro propyl formal or BDNPA/F, methyl nitrato ethyl nitramine or methyl NENA, ethyl NENA, mixtures thereof and the like. Binders that are useful for the present invention include cellulose acetate butyrate, ethyl centralite, oxetane thermoplastic elastomers, nitrocellulose, HYTREL and ESTANE polymers, and the like.
