In order to meet the needs of customers, carbon fiber manufacturers have developed a variety of fibers with different uses to make full use of the excellent characteristics of carbon fiber. This paper will comprehensively analyze 10 common application methods and uses of carbon fiber products.
1. Continuous long fiber
Product features: the most common product form of carbon fiber manufacturers. The bundle is composed of thousands of monofilaments, which can be divided into three types according to twisting methods: NT (never twisted), UT (untwisted), TT or st (twisted), among which NT is the most commonly used carbon fiber dimension.
Main uses: mainly used for CFRP, CFRTP or C / C composite materials and other composite materials, applications include aircraft / aerospace equipment, sporting goods and industrial equipment parts.
2. Staple yarn
Product features: short fiber yarn for short. Yarn spun by short carbon fiber, such as general pitch based carbon fiber, is usually in the form of short fiber.
Main uses: thermal insulation materials, antifriction materials, C / C composite parts, etc.
3. Carbon fiber fabric
Product features: it is made of continuous carbon fiber or carbon fiber short yarn. According to the knitting 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 uses: the same as continuous carbon fiber, it is mainly used for CFRP, CFRTP or C / C composites and other composite materials, and its application fields include aircraft / aerospace equipment, sporting goods and industrial equipment parts.
4. Carbon fiber braided belt
Product features: it belongs to a kind of carbon fiber fabric, which is also woven by continuous carbon fiber or carbon fiber yarn.
Main uses: mainly used for resin based reinforced materials, especially for tubular products.
5. Chopped carbon fiber
Product features: different from the concept of carbon fiber short yarn, it is usually made of continuous carbon fiber after short cutting. The short cutting length of the fiber can be cut according to the customer’s demand.
Main uses: it is usually used as a mixture of plastics, resins, cement, etc. by mixing into the matrix, it can improve the mechanical properties, wear resistance, conductivity and heat resistance; In recent years, chopped carbon fiber is the main reinforcing fiber in 3D printing carbon fiber composites.
6. Grinding carbon fiber
Product features: as the carbon fiber is brittle material, it can be prepared into powder carbon fiber material after grinding treatment, namely grinding carbon fiber.
Main uses: similar to chopped carbon fiber, but rarely used in the field of cement reinforcement; It is usually used as a mixture of plastics, resins and rubbers 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 cushion. Firstly, the short fibers are layered by mechanical carding and then prepared by acupuncture; Also known as carbon fiber non-woven fabric, belongs to a kind of carbon fiber woven fabric.
Main uses: thermal insulation material, molded thermal insulation material base material, heat-resistant protective layer and corrosion-resistant layer base material, etc.
8. Carbon fiber paper
Product features: it is made of carbon fiber by dry or wet papermaking process.
Main uses: antistatic plate, electrode, loudspeaker cone and heating plate; In recent years, the hot applications are new energy vehicle battery cathode materials.
9. Carbon fiber prepreg
Product features: semi hardened intermediate material made of carbon fiber impregnated with thermosetting resin, with excellent mechanical properties and wide application; The width of carbon fiber prepreg depends on the size of processing equipment. Common specifications include 300 mm, 600 mm and 1000 mm width prepreg.
Main applications: aircraft / aerospace equipment, sporting goods, industrial equipment and other fields that urgently need lightweight and high performance.
10. Carbon fiber composite
Product features: injection molding material made of thermoplastic or thermosetting resin and carbon fiber. The mixture is made by adding various additives and chopped fiber, and then composite process.
