Manufacture method of high-performance recyclable airscrew for unmanned aerial vehicles

Abstract

The invention relates to a manufacture method of a high-performance recyclable airscrew for unmanned aerial vehicles. The manufacture method includes: making a core with 15-30% by weight of cork wood,evenly and tightly wrapping the surface of the core with 30% by mass of carbon fiber cloth, adding carbon fiber PA66 modified material, and performing high pressure resin transfer molding. The manufacture method has the advantages that the cord wood is used herein as a base, giving the advantages of light weight and easy attraction for other materials; carbon fiber is used as a basic reinforcingmaterial; the carbon fiber PA66 modified material is used as a filling dispersive material; the three materials provide an interface of certain binding strength; load that a resin base bears is transferred to reinforcing fibers through the interface so that the reinforcing effect of the reinforcing fibers is given to full play and the overall strength of the composite herein is improved; an airscrew manufactured herein has integrated structure made by one-off mold pressing and features high strength, light specific weight, recyclability and the like.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle components, in particular to a method for manufacturing a high-performance recyclable unmanned aerial vehicle propeller. Background technique [0002] Unmanned Aerial Vehicle (UAV), referred to as unmanned aerial vehicle (UAV), is a new concept of weaponry in rapid development. It has the advantages of flexible maneuvering, quick response, unmanned flight, and low operation requirements. At present, the scope of use of UAVs has been expanded to the three major fields of military, scientific research, and civilian use, specifically in power, communications, meteorology, agriculture, ocean, exploration, photography, disaster prevention and reduction, crop production estimation, anti-drug anti-smuggling, border patrol, Public security anti-terrorism and other fields are widely used. [0003] Due to the characteristics of drones, the materials required to make drones have the characteristics of...

AI Technical Summary

Problems solved by technology

[0007] However, if all epoxy resin (EP) / carbon fiber (CF) composite materials are used to make drone materials, there will also be certain problems. The first is that the price of composite materials is relatively high, and the second is that the specific gravity of composite materials will be relatively heavy.

[0008] The prior art uses carbon fiber reinforced resin composite materials and foam core materials to prepare composite materials with a foam sandwich structure. Although the mechanical and safety properties meet the requirements, the composition of the carbon fiber reinforced resin composite materials with a foam sandwich structure is complex. , during the preparation process, due to the inconsistency of the compatibility between the components and the large gradient of surface tension, the surface of the product will cause defects such as protrusions, depressions, flow lines or pores due to different stresses.
