Yog lawm
Cov pa roj carbon fiber ntau yog conductive. Cov pa roj carbon fiber ntau muaj qee yam conductivity vim nws cov qauv lattice tshwj xeeb thiab cov khoom siv tshuaj lom neeg. Txawm hais tias nws cov conductivity txawv nyob ntawm qhov kev npaj, feem ntau, carbon fiber yog cov khoom siv hluav taws xob.
Conductive mechanism ntawm carbon fiber xav
Cov khoom siv hluav taws xob ntawm carbon fiber ntau yog los ntawm nws cov qauv graphite microcrystalline. Cov pa roj carbon atoms nyob rau hauv cov pa roj carbon fiber ntau tsim ib tug loj π daim ntawv cog lus los tsim ib tug nruam zog band, yog li ntawd txhua carbon atom muaj peev xwm pab tau ib tug dawb- txav electron mus cuag conductivity. Tsis tas li ntawd, qhov kev tiv thaiv ntawm cov pa roj carbon fiber tsawg, txog 1200x10^-8 ~ 3000x10^-8Ω, uas ua rau carbon fiber xav tau cov khoom siv zoo tshaj plaws.
