Qhov tshwm sim ntawm cov roj carbon fiber muaj sau dua keeb kwm ntawm cov ntaub ntawv thiab kev tsim khoom lag luam. Ua raws li cov iav fiber ntau, carbon fiber sawv cev rau lwm qhov kev tshawb nrhiav hauv av hauv av. Nws cov khoom tshwj xeeb-siab, lub siab ua hauj lwm, kev sib kis hluav taws xob, ua rau nws kis tau hluav taws xob, tau ua nws lub pob kws ntawm cov khoom siv thev naus laus zis. Tshawb nrhiav rau hauv cov pa roj carbon fiber txuas ntxiv ua ntej, thiab carbon fiber ntau composites yog tam sim no dav nyob rau hauv ntau kev lag luam.
Thawj zaug tsim nyob rau xyoo 1950, carbon fiber underwent peb lawm xyoo dhau los ua ntej high-ua rau muaj kev tshawb fawb thiab kev nce qib thev naus laus zis. Carbon fiber yog ib qho tshwj xeeb cov khoom siv tau tsim cov pa roj carbon, tsim los ntawm kev ruaj khov, hluav taws xob, thiab cov txheej txheem teeb meem. Nws cov ntsiab lus carbon ntau thiab tsis tau melting cov yam ntxwv thaum tshav kub kho kom paub qhov sib txawv ntawm cov ntaub ntawv.
Cov Khoom Siv Lub Cev
Carbon Fiber kev nthuav tawm cov kev coj ua thermal vim yog qhov tseem ceeb anisotropic xwm ntawm nws cov muaju graphite. Tsis zoo li cov khoom siv cov khoom siv ntau, nws cov tshav kub tshwj xeeb tseem nyob ntawm qhov sib txawv ntawm cov qib ntawm graphitization. Thermal conductivity nyob rau hauv cov ntaub ntawv carbon tso cai rau lotice vibrations dua li hluav taws xob txav, diverging los ntawm Wiedemann-Franz txoj cai pom hauv cov hlau. Parallel rau cov lus sib dhos, nws thermal conductivity rivals uas ntawm tooj dag. Hluav Taws Xob, Carbon fiber qhia tau ua qauv zoo sementonductor-zoo li cov khoom, nrog resistivity cuam tshuam los ntawm cov cab kuj kev txiav txim siab thiab ua cov dej sov.
Tshuaj Tshuaj Muaj Zog
Raws li cov roj carbon cov roj carbon ntau, carbon fiber qhia kev ua yeeb yam hauv qab cov qauv txheej txheem, reacting tsuas yog nrog cov accidizing muaj zog lossis cov neeg sawv cev tshwj xeeb. Hauv qab no 250 degree, nws undergoes minimal hloov kev hloov pauv, xws li oxidation lossis compound tsim. Nws cov qauv ntxig, nrog kwv yees li 25% porosity, tswj hwm roj desorption thaum cua sov, txhim kho hluavtaws ruaj khov thiab haum rau cov ntawv thov electrothermal.
Cov ntawv thov cov pa roj carbon fiber ntau
Niaj hnub nimno fiber composites feem ntau poob rau hauv cov thermosetting qeb, feem ntau sib txuas cov roj carbon fiber nrog epoxy resins los ntawm kev kho tshwj xeeb. Cov ntawv sau ua ke no khaws cov ntsiab lus zoo ntawm carbon fiber ntau-lub zog, muaj zog tshaj plaws-thaum ua kom muaj zog ntawm cov hlau hauv lub zog-rau-luj txoj kev sib piv.
Hauv cov chaw muaj kev muaj, cov roj carbon fiberites ua cov khoom siv kub xws li foob pob hluav taws, thermal shubher, thiab huab cua tus kav hlau txais xov. Lawv tseem suav cov khoom tseem ceeb tshaj plaws-cov kabmob hauv cov dav hlau wings, Tail cov rooj sibtham, thiab tsaws iav. Hauv kev thauj mus los, kev siv ntau ntawm automotive Tsav tsheb Shafts thiab tshem tawm cov tshuab ua marine engineering cov khoom noj haus dej nuv ntses.
Los ntawm Aerospace hloov kho lub zog txuas ntxiv mus ntxiv rau kev rov ua dua tshiab engetine contribering, ntsuas tsis muaj kev ua tau zoo nrog cov hom phiaj ruaj khov. Lawv txoj kev taug kev los ntawm Kev Lag Luam Xav Txog Kev Lag Luam Qhov Tseem Ceeb Tshaj Plaws uas Tsis nthuav dav tseem nthuav thoob plaws hauv ntiaj teb kev lag luam.
