Carbon fiber has a series of excellent properties such as high strength, high modulus, corrosion resistance, and small thermal expansion coefficient, so its application fields are 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 fibers. This article will comprehensively analyze 10 application methods and uses of carbon fiber products.

  1. Continuous long fiber

  Product features: The most common product form of carbon fiber manufacturers, the tow is composed of thousands of monofilaments, 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-twisted yarn and Z-twisted yarn (as shown in the figure below).

  Main application: mainly used for composite materials such as CFRP, CFRTP or C/C composite materials, and the application fields include aircraft/aerospace equipment, sporting goods and industrial equipment parts.

  2. Short fiber roving

  Product Features: Spun yarn for short, the yarn spun from short carbon fiber, such as general-purpose pitch-based carbon fiber, is usually in the form of short fiber.

  Main application: heat insulation materials, anti-friction materials, C/C composite parts, etc.

 

  3. Carbon fiber fabric

  Product features: It is woven from continuous carbon fiber or short carbon fiber roving. According to the weaving method, carbon fiber fabric can be divided into woven fabric, knitted fabric and non-woven fabric. At present, carbon fiber fabric is usually woven fabric.

  Main use: Same as continuous carbon fiber, mainly used for composite materials such as CFRP, CFRTP or C/C composite materials, and the application fields include aircraft/aerospace equipment, sporting 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 short carbon fiber yarn.

  Main application: Mainly used for resin-based reinforcement materials, especially for the production and processing of tubular products.

  5. Chopped carbon fiber

  Cut according to customer needs.

  Main application: Usually used as a mixture of plastics, resins, cement, etc., the mechanical properties, wear resistance, electrical conductivity and heat resistance can be improved by mixing into the matrix; in recent years, the reinforcing fibers in 3D printing carbon fiber composite materials are mostly chopped carbon fibers Mainly.
 

 

 

  6. Grinding carbon fiber

  Product features: Since carbon fiber is a brittle material, it can be prepared into powdered carbon fiber material after grinding, that is, ground carbon fiber.

  Main application: Similar to chopped carbon fiber, but rarely used in the field of cement reinforcement; usually used as a mixture of plastics, resins, rubber, etc. to improve the mechanical properties, wear resistance, electrical 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 carding and other methods, and then prepared by acupuncture; also known as carbon fiber non-woven fabric, it is a kind of carbon fiber woven fabric.

  Main application: thermal insulation material, base material of molded thermal insulation material, base material of heat-resistant protective layer and corrosion-resistant layer, etc.

  8. Carbon fiber paper

  Product features: Carbon fiber is used as raw material, and it is prepared by dry or wet papermaking process.

  Main applications: anti-static plates, electrodes, speaker cones, and heating plates; hot applications in recent years are cathode materials for new energy vehicle batteries, etc.

 

  9. Carbon fiber prepreg

  Product features: a semi-hardened intermediate material made of carbon fiber impregnated with thermosetting resin, which has excellent mechanical properties and is widely used; view more composite material process articles and log on to the composite material application technology network. The width of carbon fiber prepreg varies according to the size of processing equipment The picture below shows the 300mm and 600mm width prepreg processed and produced with the domestic M55J grade carbon fiber produced by Ningbo Materials Institute.

  Main applications: areas such as aircraft/aerospace equipment, sporting goods and industrial equipment that are in urgent need of lightweight and high performance.



10. Carbon fiber composite

  Product features: Injection molding material made of thermoplastic or thermosetting resin mixed with carbon fiber, the mixture is made of various additives and chopped fibers, and then compounded.

  Main application: Relying on the material's excellent electrical conductivity, high rigidity, and light weight advantages, it is mainly used in office automation equipment shells and other products.
