During the process of pasting carbon fiber cloth, due to the unqualified carbon fiber cloth and supporting carbon fiber glue; the surface treatment of the concrete structure during construction does not meet the requirements; or the construction method of pasting carbon fiber cloth does not meet the requirements, etc., which may cause the surface of the carbon fiber cloth has some small bubbles and hollow phenomenon.
How can we avoid the hollowing of carbon fiber cloth?
First of all, the following aspects of the construction process should be paid attention to: before pasting carbon fiber cloth, the uneven parts of concrete should be polished; when brushing carbon fiber glue, the thickness of glue should be consistent; when pasting the carbon fiber cloth, we need to keep the cloth flat. The scraper shall completely discharge the air when the cloth is scraped; after pasting the carbon fiber cloth, the glue must be evenly brushed.
After seeing the operational precautions in the construction process, we can easily find that with only a little care, hollowing problems can easily be avoided. However, if it is the quality of the carbon fiber cloth and the supporting carbon fiber glue that cause this problem, we need to select a reliable carbon fiber cloth manufacturer when purchasing the carbon fiber cloth.
Solutions to the hollowing caused by the quality problems of carbon fiber cloth
The hollow drums caused by the quality problems of carbon fiber cloth mainly include: poor carbon fiber raw materials, insufficient monofilament strength, and inconsistent carbon fiber tow gaps. The carbon fiber cloth produced by Nanjing Mankate is made of imported carbon fiber yarn. The strength of the monofilament is as high as 5019 MPa. The flatness is high, and the cutting is not scattered. There is no flattening, and the dipped effect is good. We have the same test equipments in the industry as the test center.
You can also visit Nanjing Mankate's factory to see the tensile strength, elastic modulus, and elongation at the scene. After you have read the satisfactory data, and then you place your orders at ease!
