Facts About Carbon Fiber - Properties & Uses

A Botany graduate, Nithya Venkat enjoys researching and writing about topics that interest her.


Carbon fiber is five times stronger than steel. It is lightweight and highly malleable. Carbon fiber is made up of thin strands of carbon, thinner than human hair. These strands can be woven into any shape and further strengthened by using plastic resin. Carbon fiber is used in the manufacture of many products.

How is carbon fiber made?

Carbon fibers are made from organic polymers. The organic polymers consist of long strings of molecules bound by carbon atoms.

About 90% of carbon fibers are made from the polyacrylonitrile (PAN) process, and the remaining ten percent is made from rayon or petroleum pitch. The manufacture of carbon fiber is partly chemical and partly mechanical.


The raw material used to make carbon fiber is drawn out into long strands and then heated to high temperatures in an anaerobic environment (without oxygen). During this process, the carbon fiber atoms do not burn instead, they vibrate with high intensity shaking off all the non-carbon atoms.


After carbonization, the surface of the carbon fibers is oxidized to increase the bonding properties of the surface; this is done so that the carbon fibers can chemically bond well with any coating material. Oxidation involves immersing the fibers in gasses or liquids.

Gasses that are used for oxidation are air, carbon dioxide, or ozone. Liquids that are used for oxidation are sodium hypochlorite or nitric acid.


The next step after surface treatment is sizing. The carbon fibers are coated to strengthen and protect the fibers from damage. Epoxy resin, polyester, nylon, urethane are some of the materials that are used to coat carbon fiber.

The coated fibers are rolled onto huge cylinders called bobbins. These bobbins are loaded onto spinning machines that weave the fibers into yarns of various sizes.

Evolution of Carbon Fiber

Thomas Edison used carbon fiber filaments for his experiments with light bulbs in 1879. He created the carbon fibers by heating bamboo. These carbon fibers were resistant to fires, thereby making them ideal for his light bulb experiments.

In 1958, Roger Bacon made carbon fibers out of rayon material, but the carbon fibers he made with rayon were not very strong.

The Royal Aircraft Establishment at Farmborough, Hampshire, UK, developed very strong carbon fibers. Rolls Royce used this while manufacturing their aircraft engines.

Nowadays, carbon fibers are made from PAN (polyacrylonitrile), rayon, or petroleum pitch.

Uses of Carbon Fiber

Carbon fiber felts used to store thousands of megawatts of energy generated by wind turbines and solar panels.

Carbon fiber is used in the manufacture of sporting goods like golf shafts, rackets, skis, snowboards, hockey sticks, fishing rods, and bicycles. The lightweight and tensile strength properties of carbon fiber make it an ideal material to produce lightweight and durable sports products.

Carbon fiber fabrics are used to strengthen concrete, steel, masonry, timber, etc. It can also be applied to walls, pipes for strengthening.

Wind turbines made from carbon fiber are lighter, stronger, and very efficient. The efficiency of a wind turbine depends mainly on the lightness of the turbine blade.

Carbon fiber reinforced plastic is used in the manufacture of race cars due to its lightweight and strength.

In the field of medicine, carbon fibers are used in the manufacture of x-ray equipment, surgery equipment, prosthesis, and implants.

Carbon Fiber in Air Crafts

Carbon fiber is used to make parts of aircraft. The fuel used by an aircraft is considerably less when the weight of the aircraft is reduced. The lightweight yet durable carbon fiber helps to reduce the overall weight of the aircraft.
