Txoj kev ntawm niaj hnub carbon fiber industrialization yog precursor fiber carbonization txheej txheem. Cov muaj pes tsawg leeg thiab cov ntsiab lus carbon ntawm peb hom raw fibers yog qhia nyob rau hauv lub rooj.
Lub npe ntawm cov khoom siv fiber ntau rau carbon fiber tshuaj tivthaiv cov ntsiab lus /% carbon fiber yield /% viscose fiber (C6H10O5) n4521~35 polyacrylonitrile fiber ntau (c3h3n) n6840~55 pitch fiber C, h9580~90
Cov txheej txheem ntawm kev siv peb hom raw fibers los tsim carbon fibers suav nrog: kev kho kom ruaj khov (cua ntawm 200-400℃, los yog tshuaj kho mob nrog cov nplaim hluav taws retardant reagent), carbonization (nitrogen ntawm 400-1400℃) thiab graphitization (siab dua 1800℃nyob rau hauv argon cua). Txhawm rau txhim kho qhov adhesion ntawm carbon fiber thiab composite matrix, kev kho saum npoo, sizing, ziab thiab lwm yam txheej txheem yog xav tau.
Lwm txoj hauv kev los ua carbon fibers yog vapor loj hlob. Nyob rau hauv lub xub ntiag ntawm catalyst, discontinuous luv luv carbon fibers nrog ib tug siab tshaj plaws ntev ntawm 50 cm yuav npaj tau los ntawm cov tshuaj tiv thaiv ntawm methane thiab hydrogen ntawm 1000.℃. Nws cov qauv yog txawv ntawm polyacrylonitrile raws li los yog pitch raws carbon fiber, yooj yim rau graphitize, zoo txhua yam khoom, siab conductivity, yooj yim rau tsim intercalation compound.(Saib roj theem kev loj hlob (carbon fiber).
