What is Carbon fiber material K value means?

The K value of carbon fiber material refers to its thermal conductivity. It is a measure of how well the material conducts heat. Carbon fiber has a relatively low thermal conductivity compared to other materials, meaning it is a good insulator and does not easily transfer heat. The exact K value of carbon fiber can vary depending on the specific type and manufacturing process, but it is typically in the range of 1-10 W/m·K (watts per meter-kelvin).

As for 1k is more expensive than 3k because of the manual problem, the 1k process will be more complicated than 3k~

But 3k is the most cost-effective carbon fiber

Another point is that the grid sizes of 1k and 3k are different. The picture above is 1k plain weave size

The picture below shows 3k twill.
