Carbon fiber laminate is a pultruded material made of carbon fiber and resin. It can be used for the repair and reinforcement of the slabs and beams of concrete structures. It has light weight, high tensile strength, and simple construction. It is deeply loved by structural reinforcement engineers. In this regard, the editor specially summarized several reasons why we had to choose carbon fiber laminate for reinforcement:

1. Unique formula.

The unique resin and fiber infiltration formula that makes the resin and carbon fiber tow composite more fully, shortens the infiltration time by more than 2 times than ordinary resin, ensures that each carbon fiber tow is fully infiltrated with the resin, and maximizes the composite performance of carbon fiber.

2. Fully cured, the strength of the carbon plate is more stable

The heating is uniform and without deviation, and the strength is more stable. The electronic digital temperature control system enables the carbon fiber and resin to be uniformly heated in the mold cavity for a long time and fully cured. The numerical control hydraulic system ensures that the force applied during the pultrusion process of the carbon plate is even and without deviation, so that the strength of the carbon plate is more stable.

3. 3 unique functional groups

High-temperature curing resin with better performance. The high-temperature curing resin contains three unique functional groups. The carbon fiber and the resin produce three times the crosslinking strength, which greatly improves the performance indicators of the carbon fiber cloth. The ordinary thermosetting resin has only a single functional group, and the strength and toughness of the resin are very low, and the composite carbon fiber laminate has poor mechanical properties and aging resistance.

4. Better straightness

The surface is smoother. The independent carbon fiber tow tension constant creel and the large-tonnage hydraulic traction system make each carbon fiber have no hair before entering the dipping tank, and no scratches after exiting the dipping tank, and the distribution is more even. In order to ensure the integral curing of fiber and glue entering the mold cavity, the precise control of tension, temperature and linear speed ensures the straightness and flatness of the carbon plate.

5. Carbon plate stress is small, construction is safer

The computer-controlled tensioning system allows the fibers to be uniformly arranged before and after entering the mold cavity to avoid the stress after the carbon plate is formed to the greatest extent.

In addition, carbon fiber laminate reinforcement has many advantages. It has high tensile strength, good corrosion resistance, shock resistance and impact resistance. With underwater carbon fiber glue, even in a humid environment, the carbon plate can be stuck very firmly. Secondly, carbon fiber laminate is stronger than steel, weighs only 1/5 of steel, has higher toughness, can be coiled, and can be supplied in a larger length without overlapping. The carbon fiber laminate is resistant to acid, alkali, salt and atmospheric corrosion and does not require regular maintenance. It also protects the internal concrete structure and can achieve the purpose of double reinforcement and repair.

No matter what kind of reinforcement method is selected, the final result is for better reinforcement effect. There is no best reinforcement method but better reinforcement method. We need to continuously explore upward when strengthening carbon plates and choose better ones.
