People often ask: do you want first-class cloth or second-class cloth? Carbon fiber cloth is also known as carbon fiber cloth, carbon fiber cloth, carbon fiber braided cloth, carbon fiber prepreg cloth, carbon fiber reinforced cloth, carbon fiber fabric, carbon fiber belt, carbon fiber sheet (prepreg cloth), etc.
1. Look at the level
The tensile strength of primary carbon cloth is greater than or equal to 3400MPa, the elastic modulus is 230GPa, and the elongation is 1.6%.
The tensile strength of secondary carbon cloth is greater than or equal to 3000MPa, the elastic modulus is 200GPa, and the elongation is 1.5%.
2. Second, look at the specifications
High quality carbon fiber cloth is braided with small bundles of 12K. There are also many businesses to use more than a dozen k number to perfunctory, resulting in reduced bond quality.
The quality CFRP has a difference of less than 1.5% in length and less than 0.5% in width, while the quality CFRP has a larger difference, which can be determined by dimensional measurement.
In the final analysis, the mechanical properties of carbon fiber cloth are the basis of whether carbon fiber cloth is good or bad. In the process of reinforcement and reconstruction, we should choose a more reasonable and suitable carbon fiber cloth for construction according to the design requirements or the engineering needs, so as to ensure safety and achieve the ideal effect.
