With the continuous advancement of materials science, more and more materials have been made from carbon fiber since the beginning of the millennium. In addition to the well-known carbon fiber cloth that is often used in the reinforcement field, it also has a twin brother called prestressed carbon fiber board. So, what is the prestressed carbon fiber board?
As the name suggests, prestressed carbon fiber boards are made of carbon fiber. The prestressed carbon fiber board reinforcement is an active reinforcement technology by using the high-strength and high-elastic material properties of the carbon fiber board. The pre-tensioning of the carbon fiber board is pre-tensioned to balance the load of the original beam, thereby greatly delaying the crack, reducing the crack width, effectively increasing the structural rigidity, reducing the deflection of the structural members, relieving the strain of the internal reinforcement, and improving the yield load of the steel and the ultimate bearing capacity of the structure.
In addition, there are many advantages to using pre-stressed carbon fiber board reinforcement. It has high tensile strength, good corrosion resistance, shock resistance and impact resistance. It can be used with Nanjing Mankate underwater carbon fiber glue. Even in a humid environment, carbon board can be firmly adhered. Secondly, carbon fiber boards are stronger than steel. The mass is only 1/5 of the steel. It has high toughness and can be coiled. It can be supplied in a large length without overlapping. Finally, the carbon fiber board is resistant to acid, alkali, salt and atmospheric environment and does not require regular maintenance. And the protection of the internal concrete structure can achieve the purpose of double reinforcement repair.
Nanjing Mankate has produced prestressed carbon fiber sheets for 15 years and has accumulated rich production experience and is underwritten by Ping An Insurance. It has been widely used in Chongqing Yuzhong South Main Road, Guodian Inner Mongolia Jingyang Energy Substation, Nanjing Zhongxing Railway Company, 2014 Highway Maintenance and other projects.
