The complex phenomena of Detonation Wave (DW) propagation in PBX of 82% of HMX, with successively HTPB, as inert binder, and GAP as Energetic Binder (EB), with an initial density 99.5% TMD was studied. A thin optical multifibre strip (250 μm each fibre), connected to a fast electronic streak camera, allows the nanosecond temporal resolution not only of the behavior of coarse HMX particles, surrounded by binder, but also the fine geometrical structure of detonation and its subsequent shock waves. The results obtained with micro gap and corner turning tests, prove the influence of EB in the mechanisms of DW formation in PBX, especially in the interaction zone between binder and particles. Detonation in PBX with GAP binder shows the shock front interacting earlier in the EB space, between the coarse particles, and DW oscillations with a mean period of 1.5 times less than those observed in PBX with HTPB.
