Chopped carbon fiber specifications detailed!

First, the definition and use of Chopped carbon fiber

Chopped carbon fiber refers to carbon fiber with a length between 1-100 mm and a diameter between 4-15 microns. They have light weight, high strength, high mold, corrosion resistance, wear resistance and other excellent properties, often used in composite materials, electronic components, aerospace, automotive manufacturing and other high-tech fields.

Second, specifications and characteristics of Chopped carbon fiber

1. Average length 10-20 mm, diameter 7-10 microns

This specification of Chopped carbon fiber is relatively low in price, and has a certain flexibility and toughness, and is easy to process into various shapes of composite materials. However, its strength and modulus are relatively low, and it is generally suitable for low-load and low-strength applications.

2. Average length 20-50 mm, diameter 10-12 microns

This specification of Chopped carbon fiber has relatively high strength and modulus, which is suitable for composite materials requiring high strength and high stiffness, and the cost of processing into composite materials is relatively low. However, due to its large diameter, its surface quality and mechanical properties are relatively poor.

3. Average length 50-100 mm, diameter 12-15 microns

This specification of Chopped carbon fiber has the highest strength and stiffness and is suitable for high-load, high-strength applications, but the cost of processing into composite materials is relatively high. At the same time, due to the long length, it is easy to cross the fibers, so that the distribution uniformity of the fibers in the matrix is affected.

Three, how to choose the right specifications

Select the appropriate specifications according to the specific application scenario. In general, for applications requiring high strength and high stiffness, specifications with an average length of 50-100 mm and a diameter of 12-15 microns should be selected; For more common applications, specifications with an average length of 20-50 mm and a diameter of 10-12 microns can be selected; For low-load, low-strength applications, an average length of 10-20 mm and a diameter of 7-10 microns can be selected.

In short, different specifications of Chopped carbon fiber are different in terms of material strength, modulus, cost, etc., and should be selected according to actual needs.

【 Conclusion 】

In this paper, the definition and main uses of Chopped carbon fiber are introduced. At the same time, three specifications of Chopped carbon fiber and their respective characteristics are described in detail, and how to choose suitable specifications is proposed. It has certain reference value for readers who need to shorten carbon fiber materials.
