Embodiment 1

[0020] A method for preparing a lightweight flange made of carbon fiber forging material. The carbon fiber forging material is used as a raw material, and through a molding process, it is heated and pressurized for a certain period of time to rapidly form a lightweight flange blank, and then processed by flange machining. The hole positions are used to obtain the final finished flange. Specific steps are as follows:

[0021] 1) Preparation of materials: use self-prepared fast-curing resin matrix, and mix it with carbon fiber in a kneader in proportion to obtain carbon fiber forging material for use; wherein, the types of carbon fiber are T300, T1000, and M30. The composition of three PAN-based carbon fibers, carbon fiber The length range is between 1-100mm; the resin matrix is ​​a thermal latent epoxy resin composition, which has a storage period of more than 20 days at room temperature between 20-30°C; the mass percentage of carbon fiber in the carbon fiber forging material ...

Abstract

The invention provides a preparation method of a light-weight flange of a carbon fiber forging material. The preparation method comprises the steps of material preparing, material packing, forming, processing and the like; and a carbon fiber forging material is taken as a raw material, through a mould pressing process, and heating and pressurizing for a certain time, a light-weight flange is obtained from rapidly forming, various hole positions are machined through a flange machine, and a final finished product flange structural member is obtained. According to the preparation method, the weight is light, the weight of the rotor can be obviously reduced, and the problem that the imbalance is large due to the fact that centers of the flange and the shaft pipe are slightly misaligned in a later stage gluing process is further reduced; basic composition material and high-end carbon fiber transmission shaft material of the flange are same, so that the problems that the electric coupling corrosion and the thermal expansion coefficient are different are solved; and the connection firmness degree and the stability in a cementing process are better, the defect that a traditional metal flange is poor in corrosion resistance is overcome, the weight of the transmission shaft can be further reduced, and the transmission shaft is convenient to install and transport.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a method for preparing a lightweight flange made of carbon fiber forging material. Background technique [0002] Carbon fiber composite material is a lightweight structural material with excellent comprehensive performance. It is widely used in aerospace, military and industrial fields. It has excellent comprehensive performance compared with traditional metal materials such as steel and aluminum alloys. It has been favored by developed countries in the world. Pay attention to. At present, carbon fiber has been widely used in key structural parts such as drive shafts, but the traditional metal flange glued with it has poor corrosion resistance, increases the weight of the drive shaft, and is inconvenient for installation and transportation. Therefore, it is urgent to use a new lightweight material. To prepare flanges, improve overall performance, and achieve energy s...
