Measurements of shock initiation in the tri-amino-tri-nitro-benzene based explosive PBX 9502: Wave forms from embedded gauges and comparison of four different material lots

摘要: We have completed a series of ambient temperature (23±2°C) shock initiation experiments on four lots (batches) the insensitive high explosive PBX 9502. 9502 consists by weight 95% dry-aminated tri-amino-tri-nitro-benzene (TATB) and 5% plastic binder Kel-F 800, 3∕1 copolymer chloro-trifluoro-ethylene vinylidene-fluoride. Two were manufactured using “virgin” process. Both these had few fine TATB particles. One virgin lot was stored majority its life (>15yr) as molding powder pressed 240mm diameter 130mm thick cylinder. The other hollow hemispherical pressing. “recycle” process many recycled powder, while charge. Shock performed precisely characterized planar shocks generated impacting an exp...
