Carbon fiber is made from organic polymers, which consist of long strings of molecules held together by carbon atoms. Most carbon fibers (about 90%) are made from the polyacrylonitrile (PAN) process. A small amount (about 10%) are manufactured from rayon or the petroleum pitch process.
Carbon fiber is typically made from polyacrylonitrile, which is formed into fibers then treated to ensure they'll maintain their closely-bonded pattern. The exposure to extreme heat that follows...
To produce a carbon fiber, the carbon atoms are bonded together in crystals that are more or less aligned parallel to the fiber's long axis as the crystal alignment gives the fiber a high strength-to-volume ratio (in other words, it is strong for its size).
Delving into the carbon fiber fabrication process, one discovers a series of carefully controlled stages, each contributing to the fiber’s distinctive characteristics. From the initial polymer processing to the final surface treatments, every step matters.
A carbon fiber is a long, thin strand of material about 0.0002-0.0004 in (0.005-0.010 mm) in diameter and composed mostly of carbon atoms. The carbon atoms are bonded together in microscopic crystals that are more or less aligned parallel to the long axis of the fiber.
Carbon fiber is a graphite fiber that is extremely lightweight and strong. It is made by drawing the fiber into long strands, heating to a high temperature, and carbonizing to expel the non-carbon atoms.
Carbon fibre completely revolutionised road bike technology when it was first introduced in the 1980s. Since then use of the material has become increasingly popular, and composite technology...
What is commonly referred to as carbon fiber is a material consisting of very thin filaments of carbon atoms. When bound together with plastic polymer resin by heat, pressure or in a vacuum a composite material is formed that is both strong and lightweight.
Carbon fiber always begins with an organic polymer, known as the precursor. About 90% of the time, that precursor is polyacrylonitrile (PAN). Sometimes rayon or petroleum pitch is used instead. Organic polymers consist of long strands of molecules bonded by carbon atoms.
In simplest terms, carbon fiber is produced by pyrolysis of an organic precursor fiber in an inert atmosphere at temperatures above 982°C/1800°F. Carbon fiber manufacture, however, is a complex undertaking.
