There are two main methods for the application of carbon fiber in repair and reinforcement, one is carbon cloth repair, and the other is prestressed carbon plate reinforcement.
Application of carbon fiber composite materials in construction
The application of carbon fiber in construction was originally used for repair and reinforcement. In the 1980s, European, American and Japanese engineers and technicians began to study the repair and reinforcement of carbon fiber and composite materials in houses and bridges, and it developed rapidly in my country in the late 1990s. Because carbon fiber has the advantages of high strength, high modulus, corrosion resistance, fatigue resistance and easy processing, this new type of carbon fiber reinforced material is more and more widely used in the field of reinforced concrete reinforcement.
Carbon fiber has high strength, light weight, basically no increase in structural section size, convenient and fast construction, and simple operation. At the same time, carbon fiber is corrosion-resistant, will not rust or corrode, and has a longer life. At present, there are two main methods for the application of carbon fiber in repair and reinforcement, one is carbon cloth repair, and the other is prestressed carbon plate reinforcement.
The following are two typical applications of carbon fiber materials in the field of reinforcement:
At present, carbon fiber cloth repair and carbon plate reinforcement have been widely used in my country. The application fields of reinforcement and repair include: bridges, culverts, dams, buildings (especially cultural heritage buildings). In addition, there are also carbon fiber planting rods and carbon fiber grids for reinforcement and repair, but they are rarely used.
The following are some engineering cases of carbon fiber material reinforcement and repair:
In recent years, with the improvement of people's awareness of carbon fiber and the decline and popularization of the cost of carbon fiber materials, more designers and engineers have added carbon fiber elements at the beginning of architectural design:
And this kind of pre-construction market application is just combined with the designability of carbon fiber composite materials. As we all know, in the field of architecture, especially well-known buildings, the value of their design even exceeds the value of "the building itself". With the maturity of carbon fiber technology and the decline of cost, the application of carbon fiber and composite materials in construction will become more and more extensive....
