THE DETONATION PROPERTIES OF DATB (1, 3-DIAMINO, 2, 4, 6-TRINITROBENZENE)
Abstract
The detonation parameters of the relatively new heat-resistant, shock-insensitive explosive DATB were measured. At the normal, pressed-loaded density (1.80 g/cc), the detonation velocity is 7,6000 m/sec, and the Chapman- Jouguet pressure is 251 kb. The detonation velocity (m/sec) varies with density (g/cc). The energy of detonation is 800 cal/g and 3/1 is the value of the isentropic exponent for product gas expansion. The failure diameter was found to be 0.53 cm. When mechanical shocks are slowly applied, as in the impact-hammer machine, DATB is less sensitive than TNT, but when the shock is more rapidly applied, as in the NOL wedge test, the explosive behaves more like Composition B. Addition of 5% plastic binder desensitizes DATB to rapidly-applied shocks, causing it to fail to build up to detonation in the wedge test even though the pressure within the explosive may be as high as 82 Kb.
