Structure for connecting carbon fiber composite shaft and metal shaft

The invention discloses a structure for connecting a carbon fiber composite shaft and a metal shaft. The structure is structurally characterized by consisting of polygonal metal ends (1) and a carbon fiber composite shaft (2), wherein two ends of the carbon fiber composite shaft are respectively formed in the shape of a polygon consistent with the end shape of the polygonal metal end in a way of twining and the like; two ends of the carbon fiber composite shaft are respectively connected with the end parts of the polygonal metal ends in a bonding way; alternately, the structure consists of the polygonal metal ends (1), a metal internal layer (3) and a carbon fiber pipe (4); the end parts of the polygonal metal ends are respectively connected with polygonal holes in the interior of the metal internal layer in a sheathing way; the carbon fiber pipe is twined on the external surface of the metal internal layer, and fixed in a resin connection way. According to the structure, the defect of ...
