层状金属复合板以优良的材料和结构性能在舰船、汽车和飞行器等装备中显示了广阔的应用前景。为研究工艺因数对层状金属复合板激光弯曲成形的影响，以不锈钢碳钢层合板为研究对象，对这种层状金属复合板的激光弯曲角度和规律进行了系统的试验研究。结果表明，不锈钢碳钢层合板和不锈钢板激光弯曲存在共性，弯曲角度随着激光功率增加而增大，随着扫描速度增加而减小，随着扫描次数增加而增大，随着板厚增大而减小。同时二者也存在差异；随着不锈钢碳钢层合板宽度的增加，弯曲角度先减小后增大；在相同工艺条件下，不锈钢碳钢层合板弯曲角度大于不锈钢板的弯曲角度，并在一次固定安装下获得85.6°这一接近直角的极限弯曲角度。

Metal laminated sheets with fine material and structural performance reveal broad application prospects in ships, automobiles, aircrafts and other equipments. In order to study the influence of process factors on laser bending of metal laminated sheets, a stainless steel-carbon steel laminated sheet is chosen as the object of the research and a systematic experimental study is conducted to investigate the bending angle and transformative law of this metal laminated sheet by laser bending. The results reveal that, there are common features between stainless steel-carbon steel laminated sheet and stainless steel sheet during laser bending. For instance, the bending angle increases with the increase of laser power, scanning times and decreases with the increase of scanning velocity, the sheet thickness. Meanwhile, there are differences between them. With the increase of the sheet width, the bending angle of stainless steel-carbon steel laminated sheet decreases at first, and then increases. The bending angle of stainless steel-carbon steel laminated sheet is bigger than that of the stainless sheet in the same processing condition. And the ultimate bending angle, 85.6°, which approximates right angle, is obtained in one clamping.
