Dharka kaarboonka ee dhalaalaysa waa nooc ka mid ah maro ku daray midabo kala duwan oo xariijimo dhaldhalaalaya hab-socodka dhaqanka ee fiber-karboonka tolmada leh, si ay u sii daayaan midabo kala duwan iftiinka, jebiya monotony-ka dunta kaarboonka ee leh midabka madow oo keliya. Waxaa si weyn loogu isticmaalaa dusha isku-dhafka fiber-carbon ee kala duwan.

Maadaama qalabyada toogashada ee kala duwan iyo bandhigyadu ay leeyihiin qaraaro kala duwan, midabku waa inuu hoos yimaadaa alaabta dhabta ah.
