Carbon Fiber

Carbon fiber

The carbon fiber of PAN fibers, asphalt fibers, viscose rayon, or phenolic fiber carbonization system too. The state is divided into filaments, staple fibers; mechanical properties are divided into general-purpose and high performance type. Universal carbon fiber strength of 1000 MPa (MPa), modulus of about 100GPa. The high-performance carbon fiber is divided into the type of high strength (strength of 2000MPa, Modulus 250GPa) and model (the modulus 300GPa above,). Strength greater than 4000MPa, also known as ultra high strength type; modulus 450GPa called ultra-high model. With the development of aerospace and aviation industry, high strength and high stretch-type carbon fiber, its elongation is greater than 2%. The largest amount of polyacrylonitrile PAN-based carbon fiber.

The more common carbon-fiber polyacrylonitrile carbon fiber and pitch carbon fiber. The manufacture of carbon fiber, including fiber spinning, the thermal stability of the (pre-oxidation), carbonization and graphitization process 4. During which the chemical changes associated with, dehydrogenation, cyclization, the pre-oxidation, oxidation and deoxidation and so on. It not only has inherent intrinsic properties of carbon materials, both soft textile fibers can be processed, a new generation of reinforcing fibers. Compared with conventional glass fiber (GF), the Young's modulus is 3 times; it is compared with the Kevlar fiber (KF-49), not only Young's modulus is about 2 times, and in organic solvents , acid, alkali insoluble swelling, outstanding corrosion resistance.
 Needed carbon fiber filament can be processed into a short fiber, and its basic properties are dependent on the performance of its raw materials - carbon fiber filament. Staple fiber has the advantage of uniformly dispersed, feed forms, simple process, etc., can be applied to the carbon fiber filament is not suitable for specific areas.

First, the main technical parameters

Second, the applications
 Carbon fiber has the softness of the ordinary textiles can be processed into fabrics, carpets, seats, ribbons, paper and other materials. The traditional use of carbon fiber in addition to use as insulation material, is generally not used alone, and more as a reinforcing material added to the resin, metal, ceramics, concrete and other materials to form composite materials. Carbon fiber reinforced composite materials can be used as aircraft structural materials, electromagnetic shielding in addition to electrical materials, artificial ligament substitute materials of the body and used for fabrication of rocket casing, motor boats, industrial robots, automobile spring and driveshafts. Now has many of the filament carbon fiber production of the national grid cables use cases.

Used in the manufacture of rockets, missiles, radar, spacecraft shell, motor boats, industrial robots, automotive leaf spring and the drive shaft and other military areas.
 Construction sector: carbon fiber reinforced cement, conductive coatings, anti-static floor;
 Electric field: conducting paper, electric panels, conductive surface felt, needle felt, conductive mats;
 Shielding materials: manufacturing shielded smoke, shielding curtain;
 Insulation materials: carbon fiber reinforced refractory blank and brick, carbon fiber reinforced ceramic;
 New field of energy: wind power, friction materials, fuel cell electrodes.
 Sports & Leisure Products: golf clubs, fishing gear, tennis rackets, badminton rackets, shaft, cycling, rowing, etc.
 Enhanced modified plastics: nylon (PA), polypropylene (PP), polycarbonate (PC), phenolic (PF), polytetrafluoroethylene (PTFE), polyimide (PI).
