Novel compound material propeller

Abstract

The invention discloses a novel compound material propeller. The novel compound material propeller comprises a framework and a and covering layer, wherein the framework comprises a framework body, a mounting hole and cutouts, wherein the covering layer is adhered to the cutouts; raw materials of the framework body comprise polystyrene, polymethyl methacrylate, polystyrene, polyvinyl chloride, polyolefine, unsaturated polyester resins, styrene-butadiene-styrene triblock copolymer, ethylene-vinyl acetate copolymer, polytetrafluoroethylene resins, polyhydroxybutyrate, short-cut carbon fibers, urea-formaldehyde resins, trimethyl phosphate, zinc stearate, a dispersing agent, a silane coupling agent KH-560, and rigidity strengthening addition agents. The novel compound material propeller disclosed by the invention is high in strength, good in rigidity, light in weight, stable in structure, and excellent in weatherability, and the service life is prolonged.

Description

technical field

[0001] The invention relates to the technical field of propellers, in particular to a novel composite material propeller. Background technique

[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 toughn...
