The advantages of the CFRP external bonding method compared with other structural reinforcement methods:

1) The CFRP material has high strength and relatively light weight, which is convenient for transportation and installation, and reduces the structural load.

2) It has a wide range of applications and strong plasticity. It can be made into various types of materials to fit different surfaces. It is suitable for various buildings, structures, and bridges (main body or parts) and has a good reinforcement effect.

3) The reinforcement efficiency is high, the deflection of the reinforced beam body is reduced and the bearing capacity is increased greatly, and the reinforcement quality is more reliable, and the protection and safety are also higher.

4) The construction process of CFRP material is simple, no complicated equipment is required, the construction period is short, and the forming is fast.

The CFRP embedded reinforcement method has many advantages compared to the CFRP external attachment method, which are summarized as follows:

1) The CFRP material is wrapped in the colloid to isolate the contact of air, water, corrosive substances, and flammable substances, reduce the disadvantages of poor fire resistance, and effectively protect the working performance of the CFRP material.

2) The contact area of CFRP material with colloid and concrete is larger, the force transmission is more coordinated, the utilization rate of CFRP material becomes higher, and the material performance can be fully exerted.

3) The CFRP material embedded in the structure is less likely to fall off and peel off than the external paste, and the load-bearing capacity is improved more.

Advantages of carbon fiber cloth wrapping reinforcement technology:

1) CFRP has better flexibility and can be used in a wider range of structures, and it is flexible to repair and cut according to site requirements.

2) Compared with the sheet structure, the carbon fiber cloth can be densely pasted, and the wrapping range can effectively protect the internal concrete from external erosion.

3) Compared with other materials, the unidirectional tensile strength of carbon fiber cloth can be higher, and it can provide more protection for the concentrated load. It can be pasted in multiple layers and pasted to strengthen the bridge components can greatly improve the bending and shear resistance of the beams and slabs, and can significantly improve the stiffness and ductility of the bridge components (such as suppressing cracking, reducing deflection, etc.)
