Cov pa roj carbon fiber ntau yog cov pa roj carbon monoxide / carbon cov khoom sib xyaw ua ke ntawm carbon fiber thiab carbon matrix. Raws li cov khoom txhawb nqa ntawm diffusion txheej ntawm proton pauv membrane roj hlwb, nws plays ob lub luag hauj lwm ntawm huab hwm coj hloov mus thiab conductivity. Yog li ntawd, cov ntawv carbon fiber tsis yog tsuas yog yuav tsum muaj qhov zoo porosity, tab sis kuj zoo conductivity. Lub conductivity ntawm carbon fiber ntawv yog tsuas yog txiav txim los ntawm ob yam. Ib qho yog kev tiv thaiv kev sib cuag los ntawm kev nruj ntawm kev sib txuas ntawm carbon fiber thiab carbon matrix, thiab lwm yam yog cov conductivity ntawm carbon fiber thiab carbon matrix. Cov conductivity ntawm carbon yog ncaj qha ntsig txog microstructure thiab kev kho cua sov ntawm carbon. Cov pa roj carbon nyob rau hauv resin carbon thiab carbon fiber yog ib qho kev hloov pauv ntawm qhov nyuaj graphitization carbon. Cov qauv no tsis yog qhov zoo tshaj plaws graphite siv lead ua qauv, tab sis lub xeev hloov pauv los ntawm amorphous chaotic txheej txheej mus rau qhov zoo tagnrho graphite siv lead ua qauv. Piv nrog rau cov qauv siv lead ua graphite zoo tagnrho, cov qauv siv lead ua ntawm cov ntawv carbon fiber ntau muaj cov yam ntxwv hauv qab no: nws cov hexagonal network yog tiaj tus tab sis muaj ntau yam tsis xws luag xws li voids, dislocations thiab impurity atoms; lub network dav hlau yog distorted thiab qhov nyiam orientation tsis zoo; qhov sib txawv interlayer yog qhov loj, nruab nrab ntawm 0.336-0.344nm; crystallite loj me me, feem ntau tsis tshaj 60nm. Graphitization yog cov txheej txheem ntawm kev hloov pauv los ntawm cov txheej txheem chaotic mus rau qhov zoo tshaj plaws graphite siv lead ua qauv, thiab nws txoj kev vam meej yog tswj los ntawm graphitization kho kub thiab lub sij hawm rwb thaiv tsev. Yog li ntawd, nws yog qhov tseem ceeb heev los kawm txog cov txiaj ntsig ntawm graphitization kub ntawm cov khoom siv hluav taws xob ntawm cov ntawv carbon fiber.
