The construction quality is easy to guarantee. As the carbon fiber cloth is soft in texture, it can ensure 100% effective bonding even when reinforcing objects with uneven surfaces. If there are bubbles on the pasting surface, the air can be easily expelled by injecting the paste with a syringe, but it is more difficult to paste steel plates. The construction is convenient, no wet work is required, no large construction equipment is required, and no on-site fixing facilities are required. The carbon fiber cloth can be cut arbitrarily, the construction is simple, and the construction period is short. Thin thickness and light weight. After pasting, the weight per square meter is less than 1.0kg (including the weight of glue), and the thickness of a layer of carbon fiber cloth is only 0.111mm/0.167mm. After repair, the self-weight and external dimensions are basically not increased.

Reinforcement and repair with carbon fiber cloth can be widely used in concrete structures of various types and shapes without changing the structural shape or affecting the appearance of the structure. Carbon fiber cloth has excellent physical and mechanical properties, the tensile strength is 7-10 times higher than that of ordinary steel, and the elastic modulus is close to that of steel, which is very suitable for reinforcement and repair of reinforced concrete. Carbon fibers with extremely high tensile strength are pre-impregnated with epoxy resin to form composite reinforcement materials (unidirectional continuous fibers); they are pasted on the structure to be reinforced along the direction of tension or perpendicular to the crack direction with epoxy resin adhesive to form a new composite material, so that the reinforced adhesive material and the original reinforced concrete are subjected to stress together, thereby increasing the structure's crack resistance or shear resistance, and improving the structure's strength, stiffness, crack resistance and elongation.
