摘要
The confined explosions of HMX-based thermobaric explosives containing PTFE in a 1.43 m(3) chamber were investigated to study the oxidising ability of PTFE. This work highlights that the time of converting Al to Al2O3 was extended to nearly 200 mu s, based on the optical radiation of Al2O3. The results that were obtained with a high-speed camera concerning the afterburning reactions to PTFE showed that the duration of the fireball reduced by about 18 %. In addition, the total energy, the total impulse and the duration of the oscillation of the shock wave were increased because of PTFE. This work shows that PTFE was an effective oxidizer for an aluminized thermobaric explosive.
