Carbon fibre reinforcement includes carbon fibre cloth reinforcement and carbon fibre board reinforcement. The research on the use of carbon fibre materials for the reinforcement and repair of concrete structures began in the United States, Japan and other developed countries in the 1980s. China's technology started very late, but with the rapid development of China's economic construction and transportation, a considerable part of the existing buildings caused historical problems due to low design load standards at the time, and some buildings were difficult to meet due to changes in use functions The requirements of the current standard use urgently require maintenance and reinforcement. There are many commonly used reinforcement methods, such as enlarged section method, outer steel reinforcement method, sticky steel reinforcement method, carbon fibre reinforcement method, and so on. Carbon fibre reinforced structure repair technology is another new type of structural reinforcement technology after increasing the concrete section and bonding steel.
Carbon Fibre Cloth
Why does carbon fibre reinforcement produce hollow drums? Let ’s take a look at the Carbon Fibre Sheet Supplier. The main reason may be that the carbon fibre glue is not painted uniformly, which causes the carbon fibre reinforcement to produce hollow drums. Furthermore, during the reinforcement process, the radians of the corners of the carbon fibre reinforcement are inconsistent. Or the carbon fibre cloth that is too wide is pasted at one time, and the unevenness of the concrete surface causes the carbon fibre to bulge. In addition, if the surface of the concrete base is uneven, and the construction of sanding and screeding is not standardized, it may also cause hollowing of the carbon fibre. Another reason may be that the carbon fibre cloth is uneven, and the scraper does not completely squeeze out air when scraping the cloth.
So what should I do if the carbon fibre reinforces the hollow drum? If it is locally hollow and the area is relatively small, it can be injected with a needle; because the injection with a needle cannot completely guarantee the solution of the hollow drum of the needle cannot be injected, this method is not commonly used. If it is a large-area empty drum, cut out the empty drum directly, repair the surface with flat glue, and then paste the Carbon Fibre Cloth.
