Rivet, system and method for connecting non-metallic material and metallic material

The invention discloses a rivet, a system and a method for connecting non-metal materials and metal materials, solves the problem of large deformation of the metal materials due to rivet connection in the prior art, and has the beneficial effects of realizing stable connection of the metal materials and the non-metal materials and improving the connection strength. According to the specific scheme, the rivet for connecting the non-metal material and the metal material comprises a rivet cover and a hollow rivet body, the rivet cover is connected with the rivet body, a wedge-shaped taper angle is arranged at the end, away from the rivet cover, of the rivet body, and a rotation driving structure is arranged on the side, away from the rivet body, of the rivet cover; a cavity is formed in the hollow position inside the rivet body so that molten non-metal materials can be contained in the rivet welding process, the volume of the cavity of the rivet body can be V < cavity > = k * V < shell >, V < shell > is the volu
