Carbon fiber reinforcement divides into carbon fiber sheet reinforcement and carbon fiber plate reinforcement. Since 1980s, carbon fiber materials began to be used for concrete structural repair & reinforcement by developed countries, such as the United States and Japan. The application of carbon fiber reinforcement started relatively late in China. While with rapid development of economy and transportation, due to problems caused by original low design load and changes in the using function, a large amount of buildings can not meet the existing standard. Therefore it is urgent to repair, reinforce and strengthen these buildings.
Till now, there are several common methods for reinforcement, for example, enlarging the section, steel-encased reinforcement, carbon fiber reinforcement and so on. Comparing with the first two reinforcements, carbon fiber reinforcement abounds in easy construction, corrosion resistance, high performance in ductility, no additional weight to structural weight. It can dramatically increase the service life of buildings and decrease the cost. Therefore the carbon fiber reinforcement becomes more and more popular with people. Except the above advantages, it also abounds in high tensile strength, a wide range of applications: concrete components, steel structure and timberwork, which can increase the load bearing and seismic resistance of components.
After knowing the basic knowledge of carbon fiber reinforcement, then how to chose the most cost-effective carbon fiber materials?
Nanjing Mankate carbon fiber sheet is a kind of unidirectional carbon fiber reinforced material made by imported Toray carbon fiber filament. It has two kinds of thickness of 0.111mm (200g) and 0.167mm (300g), and many kinds of width: 100mm, 150mm, 200mm, 300mm, 500mm and other special width requirements, widely used for tensile and seismic reinforcement of structural components. And it can be regarded as carbon fiber composite material when used with NJMKT-carbon fiber impregnation adhesive, which is suitable for reinforcement of concrete and wood structure, and has reached the requirements of "Reinforced Concrete Structure Design Code GB50367-2013", This product can effectively improve bearing capacity of components, seismic performance and durability.
