Abstract：Due to its excellent property, the application amount of composite materials on the new generation airframe has gradually increased. As a result, it’s of vital importance to improve the quality of assembly process and reduce the stress during assembly process. However, composite components have different characteristics from traditional metal structures. They are large in scale, nonrigid, easy to deform due to its own weight, and with large manufacture deviation. Moreover, they are easy to be damaged when confronted forced assembly. In order to meet the requirements of composite structures during assembly process, new technologies and methods need to be developed. This research takes the Airbus A320 wing box model as an example, states the typical assembly process of composite aircraft structure, and points out some problems in the process, such as high dependence on engineering experience, difficulty in prediction of gaps, and weak ability of shape adjusting; to solve those questions, three kinds of new airframe assembly technology were developed, which are assembly simulation technologies for tolerance control of composite structures, online control technology for assembling deformation of aircraft composite panels and effect of assembling deformation of cladding panel on service performance. At last, the shortcomings and the prospects in assembly deformation control technology of aircraft composite panel are pointed out.
