Carbon fiber cloth has become a popular material for building reinforcement and has a wide range of applications. There are many kinds of carbon fiber cloth on the market, and the quality is mixed. How to judge the quality of carbon fiber cloth?
1. Tensile strength value
This value is used as the reference value to distinguish the grade of carbon fiber cloth. The tensile strength of the first class carbon fiber cloth is ≥ 34000Mpa, and the tensile strength of the second class carbon fiber cloth is ≥ 3000Mpa. The material manufacturer will have the test report, and the material will be sent to the professional laboratory to do this kind of drawing test data, or the drawing test can be carried out by spot check to obtain the pasted carbon cloth data.
2. Appearance
The carbon fiber cloth is made of longitude and latitude, the latitude is carbon fiber filament, and the longitude is hot-melt adhesive line, without serious appearance defects such as broken weft, broken weft or broken warp. A good carbon fiber tow is black and shiny, will not curl when burned, and will turn red like fine iron wire. It is smooth and soft when touched by hand. The tow is uniform, straight, smooth and conductive.
3. Specifications
The carbon fiber cloth is woven with 12K small tow and cannot be woven with large tow carbon wire larger than 12K. Although the material cost can be reduced, the reinforcement effect cannot be guaranteed.
4. Dimensions
Wide size: the size deviation of inferior carbon fiber cloth is large, and the length deviation of excellent carbon fiber cloth is not more than 1.
5. Weight
The weight of carbon fiber cloth per square meter is 200g (thickness 0.111mm) and 300g (thickness 0.167mm). The actual weight should not be lower than the standard 8.
The above is about the introduction of carbon fiber cloth. If you have any other questions, please call us.

With the development of science and technology and the progress of society, people have higher and higher requirements for the quality of materials. Therefore, carbon fiber composites have been widely used. Because of its excellent performance, carbon fiber composites are not only used in daily life, but also have its place in the military field. The better the product, the more technical it is.
How to use carbon fiber cloth to prolong its service life
1. For carbon fiber cloth, the fiber stress mode shall be designed to only bear tensile stress. 2. The rear surface of carbon fiber cloth shall be protected. The surface protection material shall be harmless to the fiber and adhesive, and shall have reliable bonding strength and mutually coordinated deformation performance with the adhesive.
