Abstract In order to reduce the weight and pursue a higher culmination ratio of large culmination ratio commercial turbofan engines, the use of composite fan blades has become the trend today. The development and application of composite fan blade are introduced, and the material application, mold design and main manufacturing process of blade are summarized, including prepreg hand lay-up/autoclave process, automatic fiber placement process/autoclave process, 3D-woven carbon fiber reinforced resin transfer molding (RTM). At the same time, the mold material selection and structural design of Hexcel, Snecma, Rolls-Royce and other foreign companies' composite fan blades are introduced respectively, and the characteristics of the three manufacturing processes are compared and analyzed. Finally, the key technologies for manufacturing composite fan blades are summarized, and it is pointed out that the manufacturing technology of composite fan blades is now developing towards the trend of mixed material forms, automation and selfadaption of manufacturing processes, diversification of tooling materials.
