Carbon fiber reinforcement includes two types: carbon fiber cloth reinforcement and carbon fiber plate reinforcement.
A considerable portion of modern buildings have historical problems due to the low design load standards at that time. Some buildings are difficult to meet the current norms due to changes in their use functions, and they urgently need maintenance and reinforcement. There are many commonly used reinforcement methods, such as increasing the section method, external steel reinforcement method, sticking steel reinforcement method, carbon fiber reinforcement method, etc. The carbon fiber reinforcement and repair structure technology is a new structural reinforcement technology after increasing the concrete section and sticking steel.
Carbon fiber reinforcement is one of the most commonly used reinforcement methods for building structures at present. Using carbon fiber cloth reinforcement has the advantages of high strength, light weight, easy cutting, simple construction, good economy, and short construction period. The carbon fiber cloth reinforcement concrete structure technology is an emerging, high-tech structural reinforcement method. The strength of carbon fiber cloth is generally more than ten times that of building steel, and the elastic modulus is at the same level as building steel and slightly improved. It is an excellent structural reinforcement material with high strength, thin material, light weight, convenient construction, and good durability and corrosion resistance. Compared with the original other reinforcement methods, carbon fiber reinforcement technology has obvious technical advantages. The technology of sticking carbon fiber cloth reinforcement is also one of the most basic reinforcement technologies of professional reinforcement companies at present.
The application of carbon fiber reinforcement technology is becoming more and more widespread. The research on carbon fiber reinforcement of concrete and reinforced concrete structures is relatively mature, while the research on carbon fiber reinforcement of masonry structures, steel structures, and wood structures is still in its initial stage.
The carbon fiber reinforcement method can be used for the bending and shear reinforcement of concrete structures, and it is widely used in the anti-seismic, anti-cracking, and anti-corrosion reinforcement of various industrial and civil buildings and structures.
· Reinforcement of concrete structures, bridges, and building beams, columns, and panels.
· Reinforcement of tunnels, harbor facilities, chimneys, warehouses, and factories.
· Protection and reinforcement of concrete, bridges, and river structures affected by salt damage.
