Carbon Fiber Reinforcement in Construction


There is more and more technical work to strengthen and rebuild building structures. Carbon fiber reinforcement is a relatively mature new technology that uses building reinforcement. Carbon fiber fabric has the advantages of high strength, high efficiency, light weight, corrosion resistance, aging resistance, practical construction and wide range of uses. Based on reinforcement theory and technical examples, the article introduces the performance of carbon fiber board and its application and analysis in the process of renovation and reinforcement of existing buildings.


1. The use of carbon fiber reinforced materials in various concrete load-bearing components

Carbon fiber itself has many advantages, such as high strength, corrosion resistance, light weight, large thickness and ease of use. By selecting appropriate and effective connecting materials, the combination of carbon fiber and concrete can be ensured to a greater extent. By applying force, carbon fiber reinforced materials can meet the reinforcement and reinforcement requirements of various load-bearing concrete structures when building structures are reinforced.


(1) Common cross-section carbon fiber reinforced concrete bending parts have been tested on common cross-section carbon fiber reinforced concrete bending parts. We can determine that the concrete part of the component obtained by using this fiber material is used for reinforcing carbon in terms of strength, stability and load capacity. Through some improvements, the overall strength of the reinforced component has also been significantly improved, and the width of the crack caused by the rupture of the component has also been significantly reduced. When the reinforced component reaches the limit of its bearing capacity, the number and width of cracks generated by the component will be greatly reduced, and the distribution of cracks will be more regular.


(2) Carbon fiber reinforced concrete pressure element The regular winding of carbon fiber on the square concrete column can significantly improve the bearing capacity and stability of the square concrete column. The bearing capacity of concrete columns can also be improved by using carbon fiber reinforcement methods. After reinforcement with carbon fiber, the compressed concrete is compressed under the load. However, due to the strong retention of carbon fiber, it ensures the passive retention of the reinforcing element and generates a corresponding lateral retention force. When a limited amount of concrete is formed, the load-bearing capacity of the concrete compression element is greatly improved.

2. The application and social and economic benefits of carbon fiber reinforced concrete structure

Carbon fiber structure reinforcement technology is a new type of reinforcement technology, and its wide application has brought huge economic advantages. Carbon fiber fabric is mainly responsible for the force of steel bars, and its main task is to improve structural members. Because of its high tensile strength, it is widely used in the reinforcement of concrete structures. The bearing capacity of ordinary profiles is higher than that of carbon fiber cloth, but they are strengthened without increasing the weight of the components and the use of free space. However, when rebuilding existing buildings, the rigidity and strength of the floor slab will be weakened to varying degrees, especially when compared with the situation without openings. There are stress concentrations and deviations on the sides and short corners of the opening. Therefore, when selecting the reinforcement method, specific analysis should be made according to the span and opening of the soil to determine the optimal reinforcement plan.


3. Conclusion

Carbon fiber structural reinforcement technology is a new type of structural reinforcement technology, and its wide application has brought huge economic advantages: carbon fiber fabrics mainly bear the force of steel bars, and its main task is to strengthen structural members. Because of its high tensile strength, it is widely used to reinforce concrete structures. Conventional profiles have higher load-bearing capacity than carbon fiber cloth, but they are strengthened without increasing the weight of the component and using free space. However, when rebuilding existing buildings, the rigidity and strength of the floor slab will be weakened to varying degrees, especially when compared to the situation without openings. Stress concentration and deviation mainly occur in the lateral and short angles of the opening. Therefore, when selecting a reinforcement plan, a specific analysis should be made according to the soil span and opening to determine the best reinforcement plan.
