With increasing service life, increasing traffic loads, and continued erosion from the natural environment, bridges face severe challenges in terms of damage and reinforcement and maintenance. Many bridges are experiencing problems such as concrete cracking, steel corrosion, aging bearings, and reduced bearing capacity. The incidence of damage on some older bridges has been increasing year by year. Despite ongoing renovations, some bridges still have these problems, impacting traffic efficiency and posing serious safety risks.

As bridge reinforcement technology continues to evolve, prestressed carbon plates, with their unique properties and advantages, have become an innovative tool in this field. Based on carbon fiber materials, they integrate advanced structural design and manufacturing processes, providing an efficient and reliable solution for bridge reinforcement.

In terms of structural design, the prestressed carbon plate reinforcement process is considered "active reinforcement." By applying prestress to the carbon plates, a reaction force is generated before the bridge structure undergoes further deformation, thereby offsetting some of the effects of external loads on the bridge and significantly increasing the bridge's load-bearing capacity and stiffness. Compared to traditional passive reinforcement methods such as bonded steel reinforcement, this active reinforcement method more effectively leverages the material's properties, enhancing the bridge's reinforcement effectiveness.

From the perspective of material properties, prestressed carbon plates use high-strength Grade I carbon fiber plates as tensioning objects, with extremely high tensile strength, far exceeding that of steel, providing strong structural support for bridges. Carbon fiber plates are also light in weight, corrosion-resistant, and durable, and can adapt to the complex working environment of bridges, reducing subsequent maintenance costs.

In terms of construction performance, compared with the prestressed steel strand process, prestressed carbon plate construction does not require large equipment, is more convenient, does not require traffic interruption during the construction process, and has a shorter construction period. It not only saves worry and time, but also greatly reduces labor costs.
