The invention relates to the field of a carbon fiber composite shaft head connection method, particularly a carbon fiber roll shaft head connection structure and method. The connection structure is characterized by comprising a pipe and a shaft head, wherein the front of the shaft head is provided with a polygonal structure; and the length of any diagonal line of the polygon is less than the internal diameter of the pipe. The connection method comprises the following steps: 1) grinding the front of the shaft head to obtain polygonal edges; 2) connecting the ground shaft heads in an interaction mode; 3) punching the superposition position of the shaft head front end and pipe by using a puncher, inserting a pin, and fixing; 4) filling a resin into the gap between the shaft head and pipe; and 5) curing the resin. The method can convert the force borne by the resin from shearing force into extrusion force, thereby enhancing the maximum bearing force and durability of the connecting shaft and solving the problem of high tendency to shedding and damage of the resin.
