Influence of Flyer Material on Morphology of Flyer Driven by Micro Charge

Numerical simulation and experimental methods were utilized to study the influence of material type on the morphology of the flyer in the field of MEMS booster train based on micro charge involving copper azides. The research results indicate that titanium is suitable for flyer material, while copper, aluminum and polyimide are not. The flyer morphology is closely related to the mechanical properties of material. The integrity of the metal flyer depends mainly on the effective plastic failure strain, while that of the non-metal flyer depends mainly on the Young's modulus.
