Carbon fiber reinforcement technology

Carbon fiber reinforcement technology as a new and efficient reinforcement technology. By sticking carbon fiber material on the surface of the member to make it firmly combined with concrete, it can improve the mechanical performance, achieve the purpose of strengthening the structure, improving the bearing capacity and seismic resistance.

Carbon fiber reinforcement technology is suitable for the reinforcement and repair of various structural types and various structural parts. Structures such as beams, slabs, columns, roof trusses, piers, bridges, cylinders, shells, etc., require that the strength of the base concrete is not lower than C15. In addition, some mechanical properties of brick masonry can also be reinforced with carbon fiber.

The working principle of carbon fiber reinforcement technology is to make carbon fiber into carbon fiber cloth. Combined with the relevant factors of the damage to the building components, a certain method is used to attach it to the surface of the building component, so as to spread the force and achieve the reinforcement effect.

First of all, carbon fiber cloth and bonding materials need to be used in carbon fiber reinforcement technology. Due to their different roles and characteristics, they need to form a perfect whole during the manufacturing process, which can enhance its stability and effective To avoid the breaking problem of single fiber under strong action.

Secondly, the carbon fiber cloth has high initial strength, strong load pulling force, and little change due to external force. The adhesive material is easily affected by external forces in the force transmission. In order to avoid the peeling of carbon fiber and building components under external force, Adhesive materials require very high initial properties and strength.

It is a technological innovation, because the traditional reinforcement method is often passively stressed, and the prestressed carbon fiber board reinforcement technology is an active force, the prestress applied by the carbon fiber board through the tensile anchoring end and the carbon sheet rubber work together and It is evenly and effectively transmitted to the beam body, which improves the bearing capacity of the component, and at the same time reduces deflection and deformation, or closes the cracks of the component, thereby improving the rigidity of the component and improving the performance at the stage of use.
