Abstract

The invention provides a fan blade and a preparation method thereof. The bearing capacity of a tenon of the fan blade can be improved. The fan blade comprises a blade body and the tenon. The tenon comprises a tenon core part and a coating layer. The outside of the tenon core part is coated with the coating layer. The tenon core part is made of metal materials. The coating layer and the blade body are made of continuous fiber-reinforced resin matrix composite.

Description

technical field [0001] The invention relates to a fan blade and a preparation method thereof, in particular to a fan blade suitable for an aero-engine and a preparation method thereof. Background technique [0002] Resin-based composite fan blades are an important technical means to reduce weight and increase efficiency of aero-engines. However, most of the current resin-based composite fan blades have a straight tenon structure, and both the blade body and the tenon are made of resin-based composite materials. If the straight tenon is changed to an arc tenon structure, the actual contact area between the tenon and the tenon can be effectively increased, the loading condition of the tenon of the blade can be improved, and the performance of the blade can be improved. However, due to the weak compression resistance of the resin-based composite material, the bearing capacity of the tenon of the fan blade made of the resin-based composite material is poor. Contents of the inv...
