激光驱动飞片加载金属箔板成形技术是一种新型微成形技术,其飞片的结构和性能是影响该技术成形能力和质量的主要因素之一。通过Spitlight 2000Nd:YAG激光器探究了复合飞片(主要由黑漆吸收层、聚酰亚胺隔热层和铝飞片组成)对激光驱动飞片加载金属箔板成形性能的影响。实验结果表明复合飞片能够增大工件的最大成形深度,同时工件形貌中心与模具中心的对中性更好,证明复合飞片在成形过程中对冲击波具有增压和均压作用,能够提高该技术的成形能力和质量。讨论了复合飞片提高成形能力和质量的原因,同时探究了激光能量和聚酰亚胺薄膜厚度对成形性能的影响。 Laser-driven fly-sheet metal foil molding technology is a new micro-forming technology, the structure and performance of its flyer is one of the main factors that affect the forming ability and quality of the technology. The effect of composite flyer (mainly composed of black lacquer absorbing layer, polyimide insulating layer and aluminum flyer) on the forming performance of laser driven flyer loaded metal foil was investigated by using Spitlight 2000Nd: YAG laser. The experimental results show that the composite flyer can increase the maximum forming depth of the workpiece, and the alignment of the center of the workpiece and the center of the mold is better. It proves that the composite flyer can enhance and equalize the shock wave during the forming process The technology’s ability to shape and quality. The reason of improving the forming ability and quality of the composite flyer is discussed, and the influence of the laser energy and the thickness of the polyimide film on the formability is also discussed.
