Fibre idasanzwe ikozwe muri karubone. Ifite ibiranga ubushyuhe bwo hejuru, kurwanya ubukana, gutwara amashanyarazi, ubushyuhe bwumuriro no kurwanya ruswa, kandi imiterere yabyo ni fibrous, yoroshye kandi irashobora gutunganyirizwa mumyenda itandukanye. Bitewe nicyerekezo cyiza cya grafite microcrystalline imiterere ya fibre axis, ifite imbaraga nyinshi na modulus kumurongo wa fibre. Ubucucike bwa fibre karubone ni buke, imbaraga zayo rero na modulus yihariye ni ndende. Intego nyamukuru ya fibre ya karubone nuguhuza hamwe na resin, ibyuma, ceramic na karubone nkibikoresho bishimangira gukora ibikoresho bigezweho. Imbaraga zihariye hamwe na modulus yihariye ya karubone fibre ikomezwa na epoxy resin yibigize ni byinshi mubikoresho byubuhanga biriho.
