    Abstract

    Metal foil forming by laser-driven flyer is a novel high-speed micro-forming technology. The structure and performance of the flyer are the main factors affecting the forming ability and the workpiece quality of this technology. A series of experiments are carried out by a Spitlight 2000 NdYAG laser in order to investigate the effects of the multi-layered flyer [composed of absorbing layer (black acrylic paint), insulating layer (polyimide film) and aluminum flyer] on the formability of metal foil forming by laser-driven flyer. Experimental results show that the multi-layered flyer can increase the maximum deformation depth of the workpiece and attain better consistency of the workpiece and the mold. Therefore, the multi-layered flyer can magnify and equalize the shock wave pressure in the forming process, which leads to the improvement in forming ability and workpiece quality. The reasons for the improvement of the forming quality using multi-layered flyers are discussed. The effects of the laser energy and the polyimide film thickness on forming ability are also studied.
