| Abstract: | The random distribution packing models of filler in the binder of composite propellant was generated regarding the propellant as a composite of filler and binder. The generation process is based on the Molecular Dynamics ( MD) method. The results showed that the MD method could generate the microstructure of propellant effectively by allowing filler to grow at a rate proportional to the filler diameter. The obtained distribution packing models of filler provides the basis for micromechanical mechanical and combustion analysis. |
