Abstract：Carbon fiber composites, aluminum alloys and titanium alloys are important materials for manufacturing aerospace vehicles. But at the same time, its shortcomings can be seen at a glance, such as the manufacturing technology is complex, the manufacturing quality requirements are extremely strict, and the manufacturing cost remains high, and the requirements for cleaning accuracy and efficiency are higher, which make the traditional cleaning methods with high pollution, poor adaptability and poor controllability to be updated. Therefore, this paper briefly describes the research status of laser cleaning in aerospace field, and with emphasis on the laser cleaning technology of three aerospace materials: Carbon fiber composite, titanium alloy and aluminum alloy. Ultimately, the literature shows that laser cleaning of surface materials of aerospace materials has remarkable effect, environmental protection and no damage to the substrate. Even under the optimal process parameters, it can effectively improve the surface properties of some materials. In addition, combined with sensing and intelligent manufacturing technology, laser cleaning can carry out controllable high-precision cleaning in the field of space-time, which will have a good application prospect.
