Abstract

The invention provides a design and processing technology of a basalt fiber propeller, and relates to the field of composite materials. The basalt fiber propeller comprises the following components inparts by weight: 100 parts of basalt fiber, 30-50 parts of epoxy resin, 10-30 parts of a modifier, 2-3 parts of a coupling agent, 10-20 parts of a curing agent, 0.05-0.1 part of an antioxidant and 0.1-0.2 part of a flexibilizer, and the processing technology of the basalt fiber propeller comprises the following steps: S1, cutting and soaking basalt fiber cloth; S2, preparing a thick glue liquid;S3, preparing a mixed thick glue liquid; s4, forming prepreg; and S5, carrying out mold pressing or autoclave forming and curing. By using the components in parts by weight and a processing technology, the propeller is light in weight, high in strength, high in toughness and low in price, and has ultraviolet radiation resistance and aging resistance.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a design and processing technology of a basalt fiber propeller. Background technique [0002] The propeller is one of the important power devices for small and medium UAVs. The performance of the propeller directly determines the performance of the UAV, and the efficiency of the propeller is closely related to the flight time and range of the UAV. Traditional drone propellers are often made of wood or plastic. Wooden propellers have the advantages of light weight, easy processing, low cost, and convenient use, but they are easily scratched, have poor resistance to rain and snow, poor weather resistance, and low efficiency. Plastic propellers are easy to process, low in cost, high in processing precision, and light in weight, but low in strength and easy to break. With the development of science and technology, there is a demand for UAV propeller flight, and propellers made o...
