[0025] See also Figure 1-5 The utility model provides a high-strength carbon fiber reinforced film, including a film body 1, an inner receiving opening 5 is opened in the middle of the bottom of the film body 1, and a middle receiving opening 4 is opened on the outer side of the inner receiving opening 5, and an outer receiving opening 3 is opened on the outer side of the middle receiving opening 4, and a side receiving opening 2 is opened on the outer side of the outer receiving opening 3, and a transverse reinforcing rib 7 and a longitudinal reinforcing rib 8 are fixedly installed on the surface of the film body 1, and the transverse reinforcing rib 7 and the longitudinal reinforcing rib 8 are vertically arranged.
[0026] Working principle: When in use, the glue can be evenly filled in the side receiving port 2, the outer receiving port 3, the middle receiving port 4, and the inner receiving port 5. The setting of the receiving port can facilitate the glue to be evenly applied to the surface of the film body 1. When bonding and fixing, the stability of the film body 1 after bonding and fixing can be improved by increasing the amount of adhesive to avoid the situation where the glue is too little and it is easy to fall off.
[0027] As a preferred embodiment, the outer accommodating opening 3, the middle accommodating opening 4 and the inner accommodating opening 5 are concentric circle structures, and the depths of the outer accommodating opening 3, the middle accommodating opening 4 and the inner accommodating opening 5 are consistent, and the depths of the outer accommodating opening 3, the middle accommodating opening 4 and the inner accommodating opening 5 are all 0.5 mm.

[0029] The setting of the side accommodating opening 2, the outer accommodating opening 3, the middle accommodating opening 4 and the inner accommodating opening 5 can be used to limit the position when applying glue, so that the glue is applied to the inside of the outer accommodating opening 3, the middle accommodating opening 4 and the inner accommodating opening 5, and overflows to the outside of the outer accommodating opening 3, the middle accommodating opening 4 and the inner accommodating opening 5. When the film body 1 is bonded, the glue on it is squeezed so that the glue on the film body 1 is evenly applied to the surface of the film body 1, thereby increasing the stability of the film body 1 during bonding.
[0030] As a preferred implementation, notches 6 are provided at both ends of the film body 1, and the notches 6 are arranged in a "U" shape, and the thickness of the film body 1 is 2 mm.

[0033] The film body 1 is made of carbon fiber, which has extremely high strength, about 5 times that of steel. This allows the use of carbon fiber reinforced film to significantly improve the strength of automotive structural parts and enhance collision safety; the high stiffness property helps reduce the deformation of the vehicle body during driving and improve the vehicle's handling stability and durability;
