Kev lag luam thiab kev tsim kho qib siab tsis ntev los no tau ua tiav ntau yam thev naus laus zis tshiab, feem ntau cuam tshuam nrog cov ntaub ntawv tshiab. Ib tus neeg siv zoo tib yam tuaj yeem pom qhov tshwm sim ntawm cov txheej txheem no ntawm qhov piv txwv ntawm cov khoom siv hauv tsev nrog kev suav nrog cov khoom sib xyaw. Tsis tas li nyob rau hauv kev lag luam tsheb, cov ntsiab lus carbon tau nthuav tawm uas ua rau muaj kev ua tau zoo ntawm kev ua si tsheb. Thiab qhov no tsis yog txhua qhov chaw uas siv carbon fiber ntau. Lub hauv paus rau cov khoom no yog carbon fibers, ib daim duab uas tau nthuav tawm hauv qab no. Qhov tseeb tiag, qhov tsis sib xws thiab kev faib tawm ntawm cov tiam tshiab sib xyaw yog nyob rau hauv qhov tsis muaj txiaj ntsig ntawm kev txawj ntse thiab lub cev zoo.

Rau cov khoom siv, cov khoom siv raw yog siv rau hauv daim ntawv ntawm ntuj lossis tshuaj fibers ntawm organic keeb kwm. Tsis tas li ntawd, raws li kev ua haujlwm tshwj xeeb, tsuas yog cov pa roj carbon atom nyob ntawm qhov qub workpiece. Lub zog cuam tshuam tseem ceeb yog qhov kub thiab txias. Cov txheej txheem thev naus laus zis suav nrog kev siv ntau theem ntawm kev kho cua sov. Nyob rau hauv thawj theem, thawj cov qauv yog oxidized nyob rau hauv qhov kub thiab txias mus txog 250 ° C. Nyob rau tom ntejNyob rau theem, kev tsim cov pa roj carbon fiber ntau dhau mus rau hauv cov txheej txheem carbonization, vim tias cov khoom siv tau rhuab hauv ib puag ncig nitrogen ntawm qhov kub siab txog 1500 ° C. Yog li, cov qauv zoo li graphite yog tsim. Tag nrho cov txheej txheem tsim khoom yog ua tiav los ntawm kev kho zaum kawg hauv daim ntawv ntawm graphitization ntawm 3000 ° C. Nyob rau theem no, cov ntsiab lus ntawm cov pa roj carbon ntshiab hauv fibers ncav cuag 99%.

carbon fiber siv nyob qhov twg?

Yog tias thawj xyoo ntawm kev nrov npe cov khoom siv tshwj xeeb hauv cov chaw tshwj xeeb, niaj hnub no muaj kev nthuav dav ntawm cov khoom siv tshuaj fiber ntau. Cov khoom siv yog yas heev thiab heterogeneous nyob rau hauv cov nqe lus ntawm muaj peev xwm ntawm exploitation. Nrog rau qhov ua tau zoo, cov peev txheej ntawm cov fibers zoo li no yuav nthuav dav, tab sis niaj hnub no cov qauv yooj yim ntawm cov khoom nthuav qhia ntawm kev ua lag luam tau coj cov duab. Tshwj xeeb, peb tuaj yeem nco ntsoov kev tsim kho kev lag luam, tshuaj, kev tsim hluav taws xob engineering, khoom siv hauv tsev, thiab lwm yam. Raws li rau cov chaw tshwj xeeb, kev siv cov pa roj carbon fibers tseem cuam tshuam rau cov tuam txhab ntawm cov khoom siv dav hlau, kev kho mob electrodes thiab radar absorbing cov ntaub ntawv.

Ua ntej ntawm tag nrho cov, cov no yog cov khoom siv hluav taws kub-resistant textile, ntawm cov uas peb muaj peev xwm paub qhov txawv fabrics, threads, knitwear, xav, thiab lwm yam. Tej zaum qhov no yog qhov dav tshaj plaws nyob rau hauv uas cov pa roj carbon fiber tau sawv cev ua lub hauv paus rau cov khoom lag luam serial ntau lawm.ntau lawm. Tshwj xeeb, cov no yog cov bearings, cov cua sov-resistant units, qhov chaw thiab ntau yam khoom uas ua haujlwm nyob rau hauv ib puag ncig hnyav. Feem ntau cov khoom sib xyaw yog tsom rau kev lag luam tsheb, txawm li cas los xij, kev tsim kho kev lag luam kuj tseem txaus siab los txiav txim siab cov lus pom tshiab los ntawm cov tuam txhab ntawm cov tshuaj fiber ntau.

Khoom Khoom

Qhov tshwj xeeb ntawm thev naus laus zis kom tau txais cov khoom siv tau tso nws cov cim ntawm kev ua haujlwm ntawm cov fibers. Yog li ntawd, siab thermal stability tau dhau los ua qhov tseem ceeb ntawm cov qauv ntawm cov khoom zoo li no. Ntxiv nrog rau cov teebmeem thermal, cov khoom siv kuj tseem tiv taus cov tshuaj lom neeg ib puag ncig. Muaj tseeb, yog tias muaj cov pa oxygen nyob rau hauv cov txheej txheem oxidation thaum rhuab, qhov no muaj kev cuam tshuam rau cov fibers. Tab sis cov neeg kho tshuab lub zog ntawm carbon fiber tuaj yeem sib tw nrog ntau cov ntaub ntawv ib txwm suav tias yog qhov nyuaj thiab tiv taus kev puas tsuaj. Qhov kev ua tau zoo no tshwj xeeb tshaj yog nyob rau hauv cov khoom siv carbon. Lwm cov cuab yeej uas xav tau ntawm cov kws tshaj lij ntawm ntau yam khoom yog lub peev xwm ntawm kev nqus. Vim lub active nto, cov fiber no tuaj yeem suav hais tias yog ib qho kev ua haujlwm zoo.
