Carbon filaments or carbon strands (on the other hand CF, graphite fiber or graphite fiber) are filaments around 5–10 micrometers in width and made for the most part out of carbon iotas. Carbon strands have a few points of interest including high firmness, high elasticity, low weight, high substance opposition, high temperature resilience and low warm development. These properties have made carbon fiber exceptionally famous in aviation, structural building, military, and motorsports, alongside other rivalry sports. In any case, they are generally costly when contrasted and comparable filaments, for example, glass strands or plastic filaments.

To create a carbon fiber, the carbon particles are fortified together in precious stones that are pretty much adjusted corresponding to the long pivot of the fiber as the gem arrangement invigorates the fiber high to-volume proportion (at the end of the day, it is solid for its size). A few thousand carbon filaments are packaged together to frame a tow, which might be utilized without anyone else or woven into a texture.

Carbon filaments are normally joined with different materials to shape a composite. When impregnated with a plastic tar and heated it structures carbon-fiber-fortified polymer (regularly alluded to as carbon fiber) which has a high solidarity to-weight proportion, and is incredibly inflexible albeit to some degree fragile. Carbon strands are additionally composited with different materials, for example, graphite, to shape strengthened carbon-carbon composites, which have a high warmth resistance.
