Precursors for carbon fibers are [[polyacrylonitrile]] (PAN), [[rayon]] and [[pitch (resin)|pitch]]. Carbon fiber filament yarns are used in several processing techniques: the direct uses are for prepregging, filament winding, pultrusion, weaving, braiding, etc. Carbon fiber yarn is rated by the linear density (weight per unit length; i.e., 1&nbsp;g/1000&nbsp;m = 1&nbsp;[[tex (unit)#Tex|tex]]) or by number of filaments per yarn count, in thousands. For example, 200&nbsp;tex for 3,000&nbsp;filaments of carbon fiber is three times as strong as 1,000&nbsp;carbon filament yarn, but is also three times as heavy. This thread can then be used to [[weaving|weave]] a carbon fiber filament [[textile|fabric]] or [[cloth]]. The appearance of this fabric generally depends on the linear density of the yarn and the weave chosen. Some commonly used types of weave are [[twill]], [[satin weave|satin]] and [[plain weave|plain]]. Carbon filament yarns can also be [[knitting|knitted]] or [[braiding|braided]]. [[Carbon-fiber reinforced polymer|Dry fabric carbon fiber composites (CFRP)]] are typically cut using [[CNC router|CNC digital cutting systems]] equipped with rotating machine knives and [[ultrasonic]] cutting method.<ref>{{Cite web |date=2025-03-06 |title=Cutting of Fiber-Reinforced Composites: Overview |url=https://www.sollex.se/en/blog/post/industrial-cutting-of-fiber-reinforced-composites-textiles-prepregs |access-date=2025-03-31 |website=Sollex |language=en}}</ref>
