Buildings are constantly damaged during use and affect their safe use. The most economical method is to reinforce and repair them.lThe application in strengthening and repairing concrete structures has attracted attention at home and abroad, and research and development have been started. In the late 1980s, a new technology for strengthening and repairing buildings with carbon fiber composite materials was developed abroad, and it was widely used in the 1990s. After the earthquake in Japan in 1994 and the reconstruction and repair after the earthquake in Taiwan, China in 1999, carbon fiber also played an important role.

There are three main aspects to consider when using carbon fiber in buildings.

First, a set of design and construction specifications that are different from traditional reinforcement and repair methods must be established.
Then, a new basic theoretical database of materials and design methods must be established. Prototype materials for new technologies, such as carbon fiber woven fabrics, unidirectional fabrics, mixed fabrics, primer resins, adhesives, and new construction equipment, are gradually forming an industry.
In general, the reinforcement and repair technology currently used in my country is still very backward, and new technologies and prototype materials are rarely used, which will be gradually eliminated.

As a new technology, carbon fiber reinforced repair is welcomed by various countries, and it has actually proved to be very effective.

Applications Of Carbon Fiber In Building Reinforcement

According to the size of the tow, it is divided into large tow industrial grade and small tow aerospace machining grade. According to the classification of mechanical properties, it is divided into general carbon fiber, high-strength high-performance carbon fiber, high-model high-performance carbon fiber, ultra-high-strength carbon fiber and ultra-high model carbon fiber.

The manufacturing of carbon fiber does not happen overnight.

The complete carbon fiber industry chain includes the complete manufacturing process from primary energy to terminal applications. Building a world-class production line and equipment assembly requires a lot of capital and running time.In addition, the carbon fiber manufacturing process includes multiple complex processes such as pre-oxidation, carbonization, and prepreg. Therefore, the carbon fiber industry chain not only means high financial barriers, but also requires high-level technical support, making it difficult for many companies to get involved in the carbon fiber industry.

The excellent characteristics of carbon fiber materials give it huge advantages in its application in the field of building reinforcement. Carbon fiber reinforcement technology is a new technology that uses carbon fiber materials to stick to the surface of concrete structures to reinforce and reinforce concrete structures. Commonly used reinforcement materials include carbon fiber cloth, carbon fiber panels, prestressed carbon fiber panels, Carbon fiber mesh etc.

Carbon Fiber Cloth Reinforcement

Carbon fiber cloth reinforcement uses adhesive to paste carbon fiber cloth on damaged parts of concrete so that it can bear force together with the concrete to achieve the purpose of reinforcing the load-bearing capacity and use function of damaged components. Carbon fiber cloth reinforcement is often used to solve structural problems such as increases in structural loads of building bridges and beams, slabs, columns, walls, etc., and changes in engineering use functions.

Carbon Fiber Plate Reinforcement

The reinforcement method of carbon fiber plates is mainly to stick the plates to the stress-bearing parts of the components to increase the bearing capacity of the area, thereby improving the bending and shear resistance of the components. It is often used for the reinforcement of large-span structures in industrial and civil construction, plate bending reinforcement, Control crack reinforcement, flexural reinforcement of plate girders, box girders, T-beams, and control cracks in reinforced concrete bridges, etc.

Prestressed Carbon Fiber Plate Reinforcement

Kaben’s new reinforcement system, the prestressed carbon fiber plate reinforcement system, changes passive reinforcement into active reinforcement. The reverse bending moment generated by applying prestress to the carbon fiber plate can offset part of the impact of the initial load, greatly improve the strength and stiffness of the reinforced concrete components, and at the same time effectively reduce the deflection deformation of the structure, and can reduce and seal cracks.

Carbon Fiber Mesh Reinforcement

The carbon fiber grid reinforcement system uses carbon fiber materials and special wet sprayed concrete mortar to bond the carbon fiber grid and concrete components to form a “sandwich” structure of mortar-grid-mortar to achieve the effect of joint stress. It is called It is widely used in the reinforcement of bridges, ancient buildings and masonry structures.

With the support of national industrial policies and the continuous technological breakthroughs of domestic carbon fiber manufacturers in the field of high-performance carbon fiber, the localization process of carbon fiber has been further accelerated, and carbon fiber composite materials will have great achievements in the field of building structure reinforcement.

The traditional method of repairing bridges is to use steel plates to surround the piers and then spot-weld the seams, and the middle needs to be filled with cement. The steel plate is easy to rust, and it is very troublesome to maintain it regularly every year. If you use carbon fiber material, you only need to stick the carbon fiber with resin, which saves a lot of work and costs, and does not require much maintenance in the later stage.Not only is it used for reinforcement and repair, but carbon fiber rods can also be directly used in building structures, and carbon fiber felts can be mixed with concrete.
