Large-scale adoption of composite blades is the most effective way to achieve ultra-high bypass ratio and low weight of aero-engine in the aerospace industry. The research progress in the manufacturing technology for resin matrix, metal matrix, and ceramic matrix composite blades is discussed in this paper. The development and application situation of the common processing technology and key manufacturing technology of aero-engine composite blades are reviewed in detail, including prepreg/molding process and three-dimensional braided/reinforced resin transfer molding process of resin matrix composite blades, molding process, pressure casting process and superplastic forming/diffusion bonding process of metal matrix composite blades, and melt infiltration process of ceramic matrix composite blades. Finally, the trend of aero-engine composite blades is discussed and the research direction to further develop key manufacturing technology of composite blades is summarized.
