Mechanical Behavior of TNAZ/Hytemp Explosives During High Acceleration

The mechanical behavior of TNAZ/Hytemp (1,3,3- trinitroazetidine/polyacrylate) explosives subjected to high acceleration has been studied in an ultracentrifuge. Pressed plastic-bonded TNAZ/Hytemp was studied as a function of the percentage of Hytemp at -10\r{}C and 25\r{}C. The percentage of Hytemp in the samples varied from 1\% to 2\%. Failure occurs when the shear or tensile strength of the explosive is exceeded. The fracture acceleration of pressed plastic-bonded TNAZ/Hytemp decreases with the increasing percentage of Hytemp in the explosive at -10\r{}C and 25\r{}C. The fracture acceleration of pressed plastic-bonded 98%/2\% TNAZ/Hytemp at 25\r{}C is about 1/3 that at -10\r{}C.
