Vim li cas Carbon fiber tau dhau los ua neeg nyiam hauv kev lag luam tsheb?

carbon fiber (CF) yog ib yam tshiab ntawm cov khoom siv fiber ntau nrog lub zog siab thiab cov qauv siab ntawm cov ntsiab lus carbon siab tshaj 95%. Nws yog tsim los ntawm flake graphite microcrystals thiab lwm cov organic fibers stacked raws axial kev taw qhia ntawm fiber thiab tau los ntawm carbonization thiab graphitization ntawm microcrystalline number case cov ntaub ntawv. Cov pa roj carbon fiber yog cov khoom siv tshiab nrog cov khoom siv kho tshuab zoo heev. Nws feem yog tsawg dua 1/4 ntawm cov hlau. Lub zog tensile ntawm carbon fiber resin composite feem ntau yog siab dua 3500Mpa, uas yog 7 ~ 9 npaug ntawm cov hlau. Tab sis cov khoom siv carbon fiber tsuas yog raws li cov kev taw qhia fiber ntau qhia tau hais tias muaj zog heev, nws cov kev cuam tshuam tsis zoo thiab yooj yim rau kev puas tsuaj, yog li kev tsim cov khoom siv feem ntau siv nws lub teeb tensile kom zoo dua thiab tsis txhob muaj kev cuam tshuam sab nraud.

Nrog rau kev kawm tshawb fawb los ntawm luv-fiber carbon fiber mus rau ntev-fiber carbon fiber, thev naus laus zis, thiab cov khoom siv carbon fiber los ua cov khoom siv cua sov tau maj mam nkag mus rau hauv kev ua tub rog thiab pej xeem. Automotive carbon fiber composites yuav siv tau raws li automotive tsav shafts, phaj springs, thav ntawv, thiab nres pads. Tam sim no, cov ntaub ntawv steel suav txog li 3/4 ntawm qhov hnyav ntawm lub cev tsheb. Yog tias tag nrho cov hlau ntawm lub tsheb tau hloov los ntawm cov khoom siv carbon fiber ntau, qhov hnyav ntawm lub cev lub tsheb yuav raug txo los ntawm 300kg, roj efficiency yuav raug txhim kho los ntawm 36%, thiab carbon dioxide emissions yuav raug txiav los ntawm 17%.

1. Daim ntawv thov ntawm lub tsheb lub cev thiab chassis, vim carbon fiber reinforced polymer matrix composite cov khoom muaj lub zog txaus thiab nruj, nws yog cov khoom siv sib sib zog nqus rau kev tsim khoom loj xws li lub cev tsheb thiab chassis. Nws tau kwv yees tias daim ntawv thov ntawm CARBON FIBER COMPOSITE MATERIAL tuaj yeem txo qhov MASS ntawm AUTOMOBILE lub cev thiab chassis los ntawm 40% ~ 60%, uas yog sib npaug rau 1/3 ~ 1/6 ntawm cov khoom loj ntawm cov qauv hlau. Lub cev sib tw lub cev ib txwm thiab lub cev hloov kho ib nrab ntawm lub tsheb yog tag nrho rau lub hom phiaj no, thiab cov teebmeem pom tau zoo heev thiab txias heev.

2. Daim ntawv thov ntawm cov ntaub thaiv npog, cov pa roj carbon fiber kuj tseem siv rau cov ntaub thaiv npog vim nws qhov kev tiv thaiv ib puag ncig thiab hnav-tiv taus cov yam ntxwv, tab sis cov khoom uas muaj cov ntaub ntawv sib xyaw carbon fiber ntau yog nyob rau sab siab, yog li hom nres nres no feem ntau yog siv hauv cov tsheb qib siab. Cov pa roj carbon fiber nres discs tau siv dav hauv cov tsheb sib tw, xws li F1 tsheb. Nws tuaj yeem txo qhov ceev ntawm lub tsheb los ntawm 300 km / h mus rau 50 km / h ntawm qhov deb ntawm 50 m, thaum lub sij hawm qhov kub ntawm lub brake disc yuav nce mus rau ntau tshaj 900 ℃, thiab lub nres nres yuav tig liab vim. nws absorbs ntau lub zog cua sov. Cov pa roj carbon fiber nres discs tuaj yeem tiv taus kub txog 2 500 ° C thiab muab kev ruaj ntseg zoo heev.

3, daim ntawv thov ntawm lub log hub, log hub manufacturing kws txawj nyob rau hauv lub teb chaws Yelemees launched lub log series, txais yuav 2 daim tsim, lub nplhaib sab nrauv yog ua los ntawm cov khoom siv fiber ntau, thiab lub hub sab hauv yog lub teeb yuag, nrog stainless hlau screws, piv nrog qhov dav dav ntawm lub log loj yog li 40% qis dua. Piv txwv li, ib lub hub 20-nti hnyav 6 kg, thaum lub hub hnyav txog 18 kg. RX-X hom siab heev tsheb tshwj xeeb lub log ua los ntawm Kahm ntawm teb chaws Aas Kiv siv CFRP muaj ib tug loj ntawm 6 kg, uas muaj peev xwm khiav ntawm kev kub ceev thiab txo lub radial inertia quab yuam ntawm lub log. Tsim los ntawm DYMAG nyob rau hauv UK, lub ntiaj teb lub lightest carbon fiber / magnesium log muaj ob feem, ib tug carbon fiber log mesh, thiab ib tug magnesium nres disc, txuas nrog tshwj xeeb titanium-plated hardware.

4, tsav ncej siv lub zog ntawm lub tsheb tsav ncej yog ntau txoj, tshwj xeeb tshaj yog yuav tsum tau dais loj torque, muab tag nrho cov kev xav txog cov carbon fiber reinforced composite khoom anisotropy, siab zog, thiab modulus ntawm tus yam ntxwv ntawm kuj tsawg, yog li siv carbon fiber ntau. reinforced composite kis ncej los hloov cov khoom hlau, ua tau raws li qhov yuav tsum tau siv. Carbon fiber ntau driveshaft tsis tsuas yog txo qhov hnyav los ntawm 60% tab sis kuj muaj kev qaug zog zoo dua thiab ua haujlwm ntev.

Raws li ntev raws li daim ntawv thov ntawm carbon fiber nyob rau hauv lub tsheb yog ua kom lub teeb yuag ntawm lub tsheb thiab ua tau raws li qhov kev thov nruj ntawm lub tsheb, nws tsis tsuas yog ua tau raws li lub ntiaj teb no thov rau lub zog txuag thiab emission txo tab sis kuj ua tau raws li qhov teeb meem ntawm roj txuag. hais txog Volkswagen.
