Abstract

The invention provides a connecting method and structure of a carbon fiber reinforced composite part and a metal part. The connecting method of the carbon fiber reinforced composite part and the metalpart includes the steps that an adhesive film layer (2) is laid on the surface of the metal part (3), and multiple carbon fiber reinforced composite prepreg layers (7) are laid on the adhesive film layer (2); each metal rod (4) penetrates through the multiple carbon fiber reinforced composite prepreg layers (7), the adhesive film layer (2) and the metal part (3); and the structures of the carbonfiber reinforced composite part and the metal part are transferred into a forming die to be heat-cured, and the multiple carbon fiber reinforced composite prepreg layers (7) are heat-cured to form thecarbon fiber reinforced composite part (1). According to the connecting method of the carbon fiber reinforced composite part and the metal part, the interlayer strength of a carbon fiber reinforced composite can be improved, the stripping-resistant capacity of the adhesive film layer for connecting the carbon fiber reinforced composite with the metal part is improved, and the bearing capacity isimproved.
