Carbon fiber (CF) sabon nau'in kayan fiber ne mai ƙarfi mai ƙarfi da matsakaicin matsakaicin abun ciki na carbon sama da 95%. Ya ƙunshi flake graphite microcrystals da sauran zaruruwan kwayoyin halitta da aka tattara tare da axial shugabanci na fiber kuma samu ta carbonization da graphitization na microcrystalline tawada kayan. Carbon fiber sabon abu ne tare da kyawawan kaddarorin inji. Adadin sa bai kai 1/4 na na karfe ba. Ƙarfin ƙarfin ƙarfin carbon fiber resin composite yana gabaɗaya sama da 3500Mpa, wanda shine sau 7 ~ 9 na ƙarfe. Amma kayan fiber carbon kawai tare da jagorar axis fiber yana nuna ƙarfi sosai, juriyar tasirin sa ba ta da kyau kuma yana da sauƙin lalacewa, don haka masana'anta na kayan aikin galibi suna amfani da fa'idar haske mai ƙarfi kuma yana guje wa ɗaukar ɓangaren tasiri.

Tare da binciken ilimi daga ɗan gajeren fiber carbon fiber zuwa fiber carbon fiber mai tsayi, fasaha, da samfuran da ke amfani da fiber carbon don yin kayan dumama sun shiga fagen soja da farar hula a hankali. Za'a iya amfani da abubuwan haɗin fiber carbon da ke ƙera motoci azaman tuƙi na mota, maɓuɓɓugan faranti, firam ɗin, da pad ɗin birki. A halin yanzu, kayan ƙarfe suna lissafin kusan 3/4 na nauyin jikin mota.
