What are the processes for cutting carbon fiber?

Cutting carbon fiber, as the name suggests, is a processing process that cuts carbon fiber material to make its length shorter. Short-cut carbon fiber has excellent mechanical properties and chemical stability and is widely used in aerospace, automobile, sports equipment and other fields. The following is a detailed description of the process of cutting carbon fiber and related information.

First, carbon fiber preparation

Before the carbon fiber cutting process, the carbon fiber first needs to be prepared. Carbon fiber is a kind of high strength fiber material made from polyacrylonitrile fiber through a series of processing processes. The process of preparing carbon fiber mainly includes oxidation, carbonization and graphitization. After these processes, the impurities in the polyacrylonitrile fiber are removed, and the carbon content in the fiber gradually increases to form a high-purity carbon fiber.

Second, the process of cutting carbon fiber

1. Fiber cutting

The first step in cutting carbon fiber is to cut the fiber. Mechanical or water-jet cutting equipment is usually used to cut long carbon fibers into short fibers of the desired length. The length of the cut staple fiber can be adjusted according to different needs, generally between 1 mm and 50 mm.

2. Fiber screening

The cut staple fibers need to be screened to remove overly long or short fibers. The purpose of screening is to obtain a uniform length of short fibers to improve the effect of subsequent processing. Commonly used screening equipment with vibrating screen, swirl screen and so on.

3. Fiber drying

The cut and screened staple fibers contain a certain amount of water and need to be dried. The purpose of drying is to remove the moisture in the fiber to improve the storage stability of the fiber and the quality of subsequent processing. Commonly used drying equipment are hot air circulation dryer, vacuum drying box and so on.

4. Fiber packaging

Dried staple fibers need to be packaged for easy storage and transportation. Common packaging methods are cartons, woven bags and so on. In the packaging process, it is necessary to pay attention to protect the quality and length of the fiber to avoid the re-damage of the fiber.

Third, the application of short carbon fiber

Short-cut carbon fiber is widely used in aerospace, automotive, sports equipment and other fields. In the aerospace field, short-cut carbon fiber can be used to manufacture aircraft structural parts, missile casings and so on. In the automotive field, short-cut carbon fiber can be used to manufacture components such as car bodies and chassis to improve the strength and durability of cars. In the field of sports equipment, cut carbon fiber is often used in the manufacture of advanced sports equipment, such as golf clubs, tennis rackets and so on.

In SUMMARY:

The carbon fiber cutting process is a series of processing processes such as cutting, screening, drying and packaging carbon fiber materials. The purpose of these processes is to prepare a uniform length, stable quality of short carbon fiber to meet the needs of different fields. Short-cut carbon fiber has excellent mechanical properties and chemical stability, and is widely used in aerospace, automobile, sports equipment and other fields. With the continuous development of science and technology and the further improvement of carbon fiber materials, short carbon fiber will have a broader application prospect in the future.
