Composite materials had become one of the most important materials for aircraft structures. However

there is still a certain gap between the application of composite materials in China and the world’s advanced level. The typical feature is that the proportion of composite materials is relatively low. Compared with metal structures

the connection is the weak link in the assembly and manufacturing of composite structures. The riveting of composite structures has a positive effect on aircraft weight reduction and manufacturing cost control

but the riveting of composite materials is prone to damage

which limits its application in key connection parts. In this paper

the mechanical connection technology of aviation composite structure

especially the application of riveting technology

is systematically introduced

including riveting process and method

composite riveting structure and fasteners used in composite riveting. The damage of the composite material during riveting mainly includes three aspects: The damage in the hole making process

the impact damage on the surface of the composite material structure during riveting

and the extrusion damage to the composite material when the upsetting head is formed and the nail rod is expanded. This paper focuses on the impact damage to composite materials caused by the installation process and the extrusion damage to composite materials caused by the expansion of rivets

and puts forward corresponding solutions

mainly from reducing the extrusion degree of composite materials caused by the expansion of nail bars and taking protective measures for composite materials. Combining with the comparison of relevant research conclusions

it is concluded that formulating reasonable process specifications

adopting advanced riveting process methods and paying attention to the protection of gaskets can effectively suppress the riveting damage of composite materials and improve the riveting quality of composite materials. Finally

the development of composite riveting technology is prospected.
