Carbon fiber cloth is a kind of reinforcing material which is often used in building reinforcement. When consulting or buying carbon fiber cloth, many people have noticed the problem of carbon fiber cloth weight. How is the weight calculated? We use the 200g/m2 and 300g/m2 carbon cloth as examples. If we use the weighing method to intercept the weight of carbon fiber cloth every time, it is not only a waste of materials, but also a trouble. Today,Horse Construction with a ruler to teach you the fast calculation of carbon fiber's weight.

First, take 12K carbon fiber cloth 200g/m2 as an example

Its weight is 0.2g/m 3k, then 12K is 0.8g/m, if you know the root number per unit area (M2) in carbon fiber bundle, then it is possible to calculate the weight of the carbon fiber cloth. We used a ruler to measure, can be seen from the diagram clearly, carbon fiber bundle length single direction one centimeter to 2.5, so the carbon fiber length of 1m single direction of the fiber bundle is 250, then we can calculate the 12K carbon fiber cloth 200g/m2 grams.

Total gram weight =0.8g/m*250 root *1m=200g

Two, take 12K carbon fiber cloth 300g/m2 as an example

From the above can be clearly seen, carbon fiber bundle length single direction one centimeter to 3.75, so the carbon fiber length of 1m single direction of the fiber bundle is 375, then we can calculate the 12K carbon fiber cloth 300g/m2 grams.

Total gram weight =0.8g/m*375 root *1m=300g

Note: 

1. fiber fabric quality test results per unit area, its allowable deviation is (+ -)3%.

2. this method can be used for carbon fibers with different gram weights.

For manufacturers, strict control of carbon fiber weight is the premise of good faith management. For consumers, the standard carbon fiber is the source of trust and the prerequisite for cooperation.
