摘要: 使碳纤维复合材料反射器的表面金属化可以有效降低电磁波在反射器表面的能量消耗,采用机器人进行喷涂可以有效解决人工喷涂产品质量不稳定以及效率低下的问题。基于机器人的喷涂过程,分析了喷涂过程的影响因素:一是机器人轨迹,包含机器人行走路径模式和相邻行走路径的间距;二是喷枪单元参数,包含各路气压值、喷涂丝材的走丝速度、喷枪的行走速度以及喷枪距离基体表面的相对高度。以某反射器为基础,确定了合适的自动喷涂参数,制备了某含有金属涂层的复合材料卫星天线反射器,孔隙率检测结果为0.162%,粗糙度结果为Ra=1.417 μm,均优于常规要求,为后续的优化使用打下了基础。

Abstract: Metallization on the surface of carbon fiber composite reflector can effectively reduce the energy consumption of electromagnetic wave on the surface of reflector, while robot spraying can effectively solve the problem of unstable quality and low efficiency of artificial spraying products. Based on the spraying process of the robot, the influencing factors of the spraying process have been analyzed. The first is the trajectory of the robot, including the walking path pattern of the robot and the distance between adjacent gun paths. The second is the parameters of the gun unit, including the air pressure, the speed of the spraying wire, the walking speed of the gun and the relative height of the gun from the base surface. Based on a reflector, the appropriate parameters of automatic spraying have been determined, and a composite satellite antenna reflector containing metal coating has been prepared. The porosity detection result is 0.162 %, and the roughness result is Ra 1.417 μm, both of which are better than the conventional requirements, laying a foundation for the subsequent optimization.
