Detailed Inventory Of The Top Ten Applications of Carbon Fiber Products

 

Carbon Fiber has a series of excellent properties such as high strength, high modulus, corrosion resistance, and low thermal expansion coefficient, so its application field is very wide. In order to meet customer needs, carbon fiber manufacturers have developed a variety of fibers for different purposes to make full use of the excellent properties of carbon fiber. This article will comprehensively analyze the 10 applications and uses of carbon fiber products.

 

Continuous Long Fiber

 

 

Product Features:

The most common product form of carbon fiber manufacturers, the bundled yarn is composed of thousands of single filaments, which are divided into three types according to the twisting method: NT (Never Twisted, untwisted), UT (Untwisted, untwisted), TT or ST (Twisted, twisted), among which NT is the most commonly used carbon fiber. For twisted carbon fiber, according to the twist direction, it can be divided into S twist yarn and Z twist yarn (as shown in the figure below).

 

 

Main Uses:

Mainly used in composite materials such as CFRP, CFRTP or C/C composites, and application areas include aircraft/aerospace equipment, sporting goods and industrial equipment parts.

 

2. Short Fiber Yarn

 

 

Product Features:

Short-fiber yarn, which is a yarn spun from short carbon fibers, such as general-grade asphalt-based carbon fibers, which are usually short-fiber products.

 

Main Uses:

thermal insulation materials, friction-reducing materials, C/C composite parts, etc.

 

3. Carbon Fiber Fabric

 

 

Product Features:

It is woven from continuous carbon fiber or short carbon fiber yarn. According to the weaving method, carbon fiber fabrics can be divided into woven fabrics, knitted fabrics and non-woven fabrics. Currently, carbon fiber fabrics are usually woven fabrics.

 

Main uses: Same as continuous carbon fiber, mainly used in composite materials such as CFRP, CFRTP or C/C composite materials, and application areas include aircraft/aerospace equipment, sports goods and industrial equipment parts.

 

4. Carbon Fiber Braided Belt

 

 

Product Features:

It is a kind of carbon fiber fabric, which is also woven from continuous carbon fiber or carbon fiber short yarn.

 

Main Use:

It is mainly used for resin-based reinforcement materials, especially suitable for the production and processing of tubular products.

 

5. Short-Cut Carbon Fiber

 

 

Product features: Different from the concept of carbon fiber short yarn, it is usually prepared by chopped continuous carbon fiber, and the chopped length of the fiber can be cut according to customer needs.

 

Main Uses:

Usually used as a mixture of plastics, resins, cement, etc., it can improve mechanical properties, wear resistance, conductivity and heat resistance by mixing into the matrix; in recent years, the reinforcing fibers in 3D printed carbon fiber composites are mainly chopped carbon fibers.

 

6. Grinding Carbon Fiber

 

 

Since carbon fiber is a brittle material, it can be prepared into powdered carbon fiber material after grinding, which is ground carbon fiber.

 

Main Uses:

Similar to chopped carbon fiber, but rarely used in cement reinforcement; usually used as a mixture of plastics, resins, rubber, etc. to improve the mechanical properties, wear resistance, conductivity and heat resistance of the matrix.

 

7. Carbon Fiber Felt

 

 

Product Features:

The main form is felt or mat, firstly the short fibers are layered by mechanical combing and then prepared by needle punching; also known as carbon fiber non-woven fabric, which is a kind of carbon fiber woven fabric.

 

Main Uses:

Thermal insulation materials, molded insulation material substrates, heat-resistant protective layers and corrosion-resistant layer substrates, etc.

 

8. Carbon Fiber Paper

 

 

Product Features:

Made of carbon fiber using dry or wet papermaking process.

 

Main Uses:

anti-static plates, electrodes, speaker cones and heating plates; hot applications in recent years include positive electrode materials for new energy vehicle batteries, etc.

 

9. Carbon Fiber Paper

 

 

Product Features:

A semi-hardened intermediate material made of carbon fiber impregnated with thermosetting resin, which has excellent mechanical properties and is widely used. The width of the carbon fiber prepreg is determined by the size of the processing equipment. The following figure shows 300mm and 600mm wide prepregs produced using domestically produced M55J grade carbon fiber from Ningbo Institute of Materials.

 

 

Main Applications:

aircraft/aerospace equipment, sporting goods, and industrial equipment, where lightweight and high performance are urgently needed.

 

10. Carbon Fiber Composites

 

 

Product Features:

Injection molding material made of thermoplastic or thermosetting resin mixed with carbon fiber. The mixture is made by adding various additives and chopped fibers, and then undergoes a composite process.

 

Main Uses:

Relying on the material’s excellent conductivity, high stiffness, and lightweight advantages, it is mainly used in products such as office automation equipment housings.
