Abstract

The invention provides a carbon fiber three-dimensional flow centrifugal fan impeller and a molding method thereof. Wheel disks and three-dimensional twisted blades of the impeller are all formed by laminating multiple layers of carbon fiber materials in the thickness direction of the carbon fiber materials in sequence. A plurality of carbon fiber reinforcing bars are clamped in each three-dimensional twisted blade to form a plurality of reinforcing ribs in the three-dimensional twisted blade. The space between the two adjacent carbon fiber materials and the space between the carbon fiber material and the adjacent carbon fiber reinforcing bar are filled with epoxy resin. The two sides, connected with the wheel disks, of the three-dimensional twisted blades are provided with a plurality oftenons correspondingly. The two wheel disks are provided with mortise holes. Carbon fiber sheets are attached to the two sides of the wheel disks. The outer surfaces of the tenon-and-mortise joints are covered with the carbon fiber sheets, and the space is filled with epoxy resin. The epoxy resin is subjected to curing through vacuum pressurizing and heating, so that the wheel disks and the three-dimensional twisted blades are subjected to curing bonding. The weight of the centrifugal fan impeller can be reduced, the anticorrosion performance can be improved. Through the welding method, the production process is greatly simplified, the period is shortened, and welding deformation of the blades is avoided.

Description

technical field [0001] The invention relates to the field of ternary flow centrifugal fan impellers, in particular to a ternary flow centrifugal fan impeller made of carbon fiber and a forming method thereof. Background technique [0002] Carbon fiber composite material is a new type of fiber material with high strength and high modulus fiber with a carbon content of more than 90% with resin as the matrix and carbon fiber filaments as the reinforcing material. It is composed of organic fibers such as flake graphite microcrystals along the fiber It is a microcrystalline graphite material obtained by stacking in the axial direction and undergoing carbonization and graphitization. Carbon fiber is "soft on the outside and rigid on the inside". It is lighter than metal aluminum, but its strength is higher than steel, and it has the characteristics of corrosion resistance and high modulus. It also has both the softness and machinability of textile fibers and the softness and machi...
