Problems solved by technology

[0002] At present, the materials of propellers generally include wood, aluminum alloy, composite materials, etc., and the structure is mainly solid or sandwich + skin. The production of wood and aluminum alloy propellers is to complete the blank on the CNC milling machine, and then surface Finished products are processed, and the production efficiency is low. These products are solid and heavy; composite material propellers usually adopt a sandwich + skin structure, and weight control is relatively easy, but the molding process of composite material propellers is relatively complicated, and prepreg is generally used. Material molding or wet hand lay-up process, low production efficiency
The strength and rigidity of the composite material propeller in the prior art cannot meet the needs of actual use, and the toughness and weather resistance of the skin material cannot meet the needs of actual use, so it is urgent to develop a new type of composite material propeller to solve the problem. Problems in the prior art
