Connecting structure of round metal part and fiber reinforced composite material

The invention discloses a connecting structure of a round metal part and a fiber reinforced composite material. The connecting structure comprises the round metal part and a composite material plate.A connecting device is arranged between the round metal part and a metal plate. A plurality of grooves are formed in the connecting face of the metal plate. When fibers in the grooves are laid, fiberbundles are placed in the grooves, and fiber filaments connected with the fiber bundles are distributed in an umbrella shape and placed in fiber cloth. The connecting device is filled and cured by using a vacuum assisted forming process and negative pressure adsorption resin. The connecting structure has the beneficial effects that 1) the problem that the composite material plate cannot be connected with a cylindrical metal material interface is solved; and 2) the fiber bundles in the grooves and the fiber filaments distributed in the umbrella shape and in the fiber cloth are integrally connected through vacuum assiste
