Ngwaahịa carbon fiber anyị na-ahụ n'ezie dị nnọọ iche na ihe carbon fiber anyị, n'ihi na a pụghị imepụta eriri naanị ya, a ga-ejikọta ya na matriks resin iji mezue mmepụta nke ngwaahịa.Otu n'ime ihe kpatara ọnụ ahịa ngwaahịa fiber ji dị oke ọnụ bụ na ọnụ ahịa carbon filaments dị oke ọnụ, yabụ anyị ga-ebu ụzọ ghọta ihe ndọtị carbon fiber.
Enwere ụdị eriri eriri atọ agbajiri agbaji, gụnyere polyacrylonitrile (PAN) carbon fiber based, pitch based carbon fiber na carbon fiber based gum.Fiber carbon fiber na-emekarị na PAN bụ nke a na-ahụkarị, na oke ahịa niile karịrị 90%, yabụ, eriri carbon thermoplastic dị ugbu a na-ezo aka na eriri carbon sitere na PAN.
A na-emepụtakwa polyacrylonitrile na mmalite.Akio Kondo chepụtara ya na Japan na 1959, wee mepụta ya na Toray na 1970. Ihe niile polyacrylonitrile carbon filament nwere nnukwu ike na njirimara nke kpakpando nlereanya.Ọ bụ Mahadum Gunma dị na Japan mepụtara eriri ahụ sitere na asphalt na 1965. Ihe ndọba carbon fiber a nwere ezigbo ikuku thermal conductivity dị elu dị ka 90OGPa, yabụ a na-etinyekarị ya na ngwa ọrụ pụrụ iche.A na-ejikarị eriri carbon nke dabeere na viscose mee ihe dị ka ihe ngwakọta maka ọta okpomọkụ ụgbọ elu na 1950, ọ bụkwa ihe a ga-eji ugbu a.Ya mere, anyị chọpụtara na ndị Japan chepụtara nke mbụ abụọ, nke mere na ụkpụrụ nrụnye nke carbon fiber tow dabeere na Toray carbon fiber ihe.
