The carbon fiber plate anchor consists of end anchors and a carbon fiber plate. Prestress is applied to the carbon fiber plate through effective clamping by the end anchors. Compared to direct carbon fiber bonding reinforcement, the prestressed carbon fiber plate anchoring system can effectively utilize the high strength of carbon fiber, saving carbon fiber usage and reducing overall project costs, while also inhibiting component deformation and crack development, effectively improving the load-bearing capacity of concrete structures. Carbon fiber composite materials have significant characteristics such as high strength, light weight, and corrosion resistance, with minimal increase in the original structure's weight, no impact on the original structure's space, and no effect on aesthetics after reinforcement.
