The frame photograph of explosive samples under drop hammer test have a furcate structure, in which the fractal dimension of the explosive is related to its impact sensitivity.
Ignition plays a determinant role in the impact detonation, and the factors that influence ignition are also the crucial ones that decide the impact sensitivity.
A series of HTPB-based PBX with different mechanical modulus were prepared by varying curing parameters or content of HTPB. The impact sensitivity of the PBX was characterized by H_(50) drop height.
The structure and firing sensitivity of percussion primer, series35 were introduced. Some impact sensitivity tests were conducted and the te-trazene content in percussion composition wasetermined.
