fibre ya karubone (CF) ni ubwoko bushya bwibikoresho bya fibre bifite imbaraga nyinshi hamwe na modulus nyinshi yibirimo karubone hejuru ya 95%.

Umubare wa fibre ya karubone bivuga urwego rwibikoresho bya karubone, nate yinganda bivuga ubwoko bwibikoresho bya karubone byakozwe na Sosiyete ya Toray mu Buyapani, naho hanze yinganda muri rusange bivuga ibikoresho bya karubone birenze urugero.T bivuga umubare wa toni yingufu zingutu igice cya fibre karubone ifite ubuso bungana na santimetero kare 1 ishobora kwihanganira.Kubwibyo, muri rusange, umubare munini wa T, urwego rwo hejuru rwa fibre karubone, nibyiza.

Ku bijyanye n’ibigize, byemejwe n’ibizamini bya siyansi ko imiti ya T300 na T700 igizwe ahanini na karubone, igice kinini cy’icyambere kikaba 92.5% naho icya 95.58%.Iya kabiri ni azote, iyambere ni 6.96%, iyanyuma ni 4.24%. Ibinyuranye, karuboni ya T700 iri hejuru cyane ugereranije na T300, naho ubushyuhe bwa karubone burenze ubwa T300, bigatuma karubone nyinshi hamwe na azote nkeya.

T300 na T700 bivuga ibyiciro bya fibre fibre, mubisanzwe bipimwa n'imbaraga zingana.Imbaraga zingana za T300 zigomba kugera kuri 3.5Gpa;T700 tensile igomba kugera kuri 4.9Gpa.Kugeza ubu, 12k gusa ya fibre fibre irashobora kugera kurwego rwa T700.
