Carbon fiber tube with shear-resistant flange and preparation method of carbon fiber tube

The carbon fiber tube comprises an inner cylinder and radial discs integrally connected to the two ends of the inner cylinder, and annular radial carbon fiber fabric layers and folded carbon fiber fabric layers are alternately bonded to the inner surfaces of the radial discs; radial ring parts are arranged at the two ends of the folded carbon fiber fabric layer, and an axial cylinder part is integrally connected between the radial ring parts at the two ends; a winding layer is wound between the axial cylinder part of the folding carbon fiber fabric layer on the innermost side in the radial direction and the inner cylinder, and a winding layer is wound between the axial cylinder parts of every two adjacent folding carbon fiber fabric layers. All the layers of structures are bonded through liquid resin to form an integral structure. The invention further discloses a corresponding preparation method. The anti-shearing performance of the flange structure under the action of tensile force is greatly improved, so t
