Description

technical field [0001] The invention relates to an automobile air conditioner assembly, in particular to an automobile air conditioner axial flow fan blade and a preparation method thereof. Background technique [0002] Automobile air conditioner axial fan blade is an important part of the exhaust system of automobile air conditioner, which mainly plays the role of ventilation and heat dissipation. Since the axial-flow fan blades of the automobile air conditioner need to rotate continuously in the working process to play a corresponding role, the high-speed friction between the axial-flow fan blades of the automobile air conditioner and the air generates heat. [0003] At present, the axial flow fan blades of automobile air conditioners are all made of polymer materials. During the long-term friction and heat generation process, the mechanical properties of the axial flow fan blades of automobile air conditioners show a gradual decline trend. In the long run, the axial flow ...
