What is carbon fiber ?

2022-09-12 Share

Carbon fiber as the most advanced high-tech material in modern industry is widely used.

Carbon fiber is made from specially treated high-quality polyacrylonitrile (PAN). Pan-based carbon fibers have 1000 to 48,000 carbon filaments, each 5-7μm in diameter, and all are microcrystalline ink structures. Carbon fibers are usually cured together with resins to form composites. These carbon-fiber components are lighter and stronger than parts made of metal, such as aluminum, or other fiber-reinforced composites.


The unique properties and designability of carbon fiber make it an ideal choice for a variety of processes and applications.
