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 connection between the metal and the carbon fiber composite shaft is overcome; under the premise of guaranteeing no damage to the fiber continuity of the carbon fiber composite shaft, the strength of connection between the metal and the carbon fiber composite shaft is improved by changing the cross-section shape of the respective connection part of the metal and the carbon fiber shaft. 1.
