Plate impact experiments on the TATB based explosive PBX 9502 at pressures near the Chapman-Jouguet state

, 2013
A series of two-stage gus-gun driven plate impact experiments on PBX 9502 (95 wt.% tri-amino-trinitro-benzene, 5 wt.% Kel-F800 plastic binder) was completed in the 28-34 GPa pressure range. This is just above the Chapman-Jouguet state of ≈ 28 GPa.
