Abstract: As a core component of compressor, the stator blades have decisive influence on the performance of aeroengine. Adopting fiber reinforced plastic composites in lightweight engine fabrication plays a key role in realizing weight reduction, large thrust-to-weight ratio and high fuel efficiency. This paper mainly presents the designing process and technical progress of fiber reinforced resin-based composite blades, and then reviews the related research on the manufacturing process of stator blades from three aspects: pre-forming, forming and cutting. In addition, underlining the importance of prophase design in the integrated development of aero-engine cold-end. Finally, by analyzing the successful foreign application of typical composite blades and according to the development trend of current design technology and molding process, the paper highlights the visible position of 2.5D woven composites in the development of aerospace engine stator blades in the future, and prospects for the future development of aeroengine composite stator blades.

Key words: fiber reinforced plastic composites, 2.5D braiding, pre-forming, closed molding
