Carbon Fiber Cloth Prestressing System
Structural Strengthening Systems
Prestressing system using carbon fiber reinforced polymer (CFRP) fabric for the structural strengthening of concrete structures
Carbon fiber cloth prestressing systems use CFRP fabric to apply active tension to concrete structures, shifting the fiber’s role from passive reinforcement to proactive load support. This approach increases the load-bearing capacity of bridges, buildings, and other structural elements. The carbon fiber cloth prestressing system consists of five main components: custom-designed anchors, carbon fiber cloth, impregnating adhesive, anchor bolts, and eccentric adjustment units. Anchors are tailored according to design specifications to ensure compatibility with each project’s structural layout and performance requirements.
| Model | Anchor block width (mm) (fixed end/tensioning end) | Anchor block length (mm) (fixed end/tensioning end) | Fixed anchor bolt (size/quantity) | Anchor locking bolt (size/quantity) | Eccentricity adjustment unit | Tension rod |
| 210/210 | 322.5/322.5 | M16/8 | M8/4 | 8 sets | M16 | |
| 210/210 | 240/240 | M16/8 | M8/4 | 8 sets | M16 |
Used for reinforcing various types of bridge girders and structural elements in buildings. Our carbon fiber cloth prestressing systems help enhance load-bearing performance and long-term stability in critical structural components.
- Offers a practical solution for structural conditions where CFRP plate prestressing systems are not suitable due to specific service environments or installation challenges.
- Based on a pulley-style mechanism, the prestressing system allows full flexibility in determining the number of CFRP fabric layers, with no fixed limitation.
- Each layer of carbon fiber cloth within the same prestressing setup receives equal stress, ensuring uniform tension and avoiding inconsistencies.
- Compared to CFRP plate prestressing systems, this approach generally results in lower material and installation costs.
- Prestressing anchors can be tailored according to project drawings and on-site requirements for better integration with structural designs.
