1. Continuous long fiber:

Product features: Carbon fiber manufacturers are more common product forms. The bundle wire consists 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), of which NT is the more 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.

Main uses: Mainly used for composite materials such as CFRP, CFRTP or C/C composite materials. Application areas include aircraft/aerospace equipment, sporting goods and industrial equipment parts.


2. Chopped carbon fiber

Product features: It is prepared from continuous carbon fiber after short-cutting processing, and the short-cutting length of the fiber can be cut according to customer needs.

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


3. Staple fiber yarn

Product features: Referred to as staple fiber yarn, yarns spun by using short carbon fibers, such as general-grade asphalt-based carbon fibers, are usually in the form of staple fibers.

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


4. Carbon fiber fabric

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

Main uses: The same purpose as continuous carbon fiber, it is mainly used for composite materials such as CFRP, CFRTP or C/C composite materials. Application areas include aircraft/aerospace equipment, sporting goods and industrial equipment parts.


5. Carbon fiber braided belt

Product features: It belongs to a kind of carbon fiber fabric, which is also woven from continuous carbon fiber or carbon fiber short yarn.

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


6.Grinding carbon fiber/carbon fiber powder

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

Main uses: It is similar to the use of chopped carbon fiber, but it is rarely used in the field of cement reinforcement; it is 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, which is first layered with staple fibers by mechanical combing and other methods, and then prepared by acupuncture; also known as carbon fiber non-woven fabric, it belongs to a kind of carbon fiber braid.

Main uses: thermal insulation materials, molded thermal insulation material substrates, heat-resistant protective layers and corrosion-resistant layer substrates, etc.


8.Carbon fiber paper

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

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


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; the width of the carbon fiber prepreg depends on the size of the processing equipment

Main uses: aircraft/aerospace equipment, sporting goods and industrial equipment with urgent needs for lightweight and high performance.


10.Carbon fiber composite

Product features: An injection molding material made of a mixture of thermoplastic or thermosetting resin and carbon fiber. The mixture is made of various additives and chopped fibers, and then the composite process is carried out.

Main uses: Relying on the excellent electrical conductivity, high stiffness and lightweight advantages of the material, it is mainly used in office automation equipment housings and other products.
