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.
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.
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.
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.
