High-performance SiC ceramic-based composite material aero-engine blade manufacturing method
The invention discloses a high-performance SiC ceramic-based composite material aero-engine blade manufacturing method. According to the invention, an aero-engine blade mold is prepared with a 3D printing technology; with a gel injection molding method, a SiC ceramic blank part with added carbon fiber is prepared; through processes such as freeze-drying and degreasing, a porous SiC ceramic preform is obtained; the preform is subjected to organic matter precursor impregnation cracking several times, and the pores of the preform are filled with a cracking product, such that preliminary compactness is achieved; and for ensuring the strength and compactness of the part, with a thermal isostatic pressing method, the high-performance SiC ceramic-based composite material aero-engine blade is manufactured. According to the method, various near-net-shape forming methods are combined, such that defects of difficult processing of the SiC material are overcome. Compared with traditional alloy blades, the SiC ceramic-based composite material aero-engine blade has the advantages of light mass and high-temperature resistance. The blade is a development trend of future aero-engine blades.
