WebCarbon fiber, also called graphite fiber, is an organic polymer made up of thin crystalline filaments. There are different formulations for producing carbon fiber with certain qualities or effects. In general, though, here’s how carbon fiber is made. The process is part chemical and part mechanical, and involves heating up long strands of ... In wire and fiber, all crystals tend to have nearly identical orientation in the axial direction, but nearly random radial orientation. The most familiar exceptions to this rule are fiberglass, which has no crystal structure, and carbon fiber, in which the crystalline anisotropy is so great that a good-quality filament will be a distorted single crystal with approximately cylindrical symmetry (often compar…
