Qhov kub thiab txias npaum li cas tuaj yeem tiv taus cov pa roj carbon fiber ntau, thiab vim li cas ntau cov khoom siv fiber ntau tsis tiv taus qhov kub thiab txias

Yuav ua li cas carbon fiber cov khoom ua tau zoo nyob rau hauv high-kub ib puag ncig? Ntawm Xinhong Kev Lag Luam, peb feem ntau nug seb peb cov khoom siv carbon fiber ntau npaum li cas tuaj yeem tiv taus. Lawv puas tuaj yeem tswj tau qhov kub thiab txias li 800 degrees? Muaj ntau qhov tsis meej pem nyob ib ncig ntawm lub ncauj lus no. Hauv tsab xov xwm no, peb yuav tham txog cov ntaub ntawv ntsig txog carbon fiber ntau thiab kub kub.

Qhov kub thiab txias npaum li cas tuaj yeem Carbon Fiber tiv taus?

Cov pa roj carbon fiber nws tus kheej muaj kev kub ntxhov heev thiab tuaj yeem suav hais tias yog cov khoom siv hluav taws xob tsis tshua muaj hluav taws xob. Txawm li cas los xij, thaum nws los txog rau carbon fiber composites, nws nyob ntawm cov khoom siv matrix siv. Carbon fiber yog muab los ntawm roj av thiab thee; Thaum pib, polyacrylonitrile (PAN) yog muab rho tawm, thiab tom qab ntawd carbon fiber yog tsim los ntawm PAN. Cov txheej txheem no yuav tsum tau siv thev naus laus zis thev naus laus zis, thiab cov theem ntawm oxidation, carbonization, thiab graphitization yuav tsum ua kom tiav ntawm qhov kub thiab txias.

Tshwj xeeb tshaj yog thaum lub sij hawm graphitization txheej txheem, uas tshwm sim ntawm kub ntawm ob peb txhiab degrees, impurities raug tshem tawm los tsim carbon fiber filaments. Yog li, lub hauv paus ntsiab lus ntawm cov pa roj carbon fiber ntau yog siab heev, muaj peev xwm tiv taus qhov kub thiab txias txog li 3000 degree thaum tswj kev ua haujlwm zoo.

Vim li cas ntau cov khoom siv roj carbon fiber ntau tsis tiv taus qhov kub thiab txias?

Raws li tau hais ua ntej, carbon fiber nthuav tawm cov cua sov ua haujlwm zoo. Txawm li cas los xij, kev tsim cov khoom siv roj carbon fiber ntau muaj ntau dua li cov pa roj carbon fiber nws tus kheej; nws kuj xav tau cov khoom siv matrix los ua kom tiav cov txheej txheem tsim cov khoom siv carbon fiber. Lub tshav kub tsis kam ntawm cov khoom siv fiber ntau nyob ntawm qhov kub tsis kam ntawm cov khoom siv matrix.

Ntau cov khoom siv carbon fiber ntau tsis tiv taus qhov kub thiab txias feem ntau vim tias feem ntau siv cov khoom sib xyaw yog kev sib xyaw ntawm carbon fiber thiab resin matrix. Cov ntsiab lus fiber ntau hauv cov khoom sib xyaw no feem ntau yog li ntawm 40% txog 45%. Yog li ntawd, lub tshav kub tsis kam ntawm cov khoom siv carbon fiber zaum kawg muaj feem xyuam rau cov cua kub tsis kam ntawm cov resin. Qhov no yog zoo li "chij txoj cai," qhov twg lub tshav kub tsis kam ntawm cov resin ua lub siab txwv rau cov khoom carbon fiber.

Feem ntau, qhov kub tsis kam ntawm tus qauv cob matrices yog nyob ib ncig ntawm 180 degree. Yog tias qhov kub siab tshaj qhov kev txwv no rau lub sijhawm ntev, nws yuav ua rau cov resin matrix yaj, cuam tshuam qhov kev ua tau zoo ntawm cov khoom. Tsis tas li ntawd, txhawm rau txhim kho kev tiv thaiv tshav kub, kev ua haujlwm siab dua resin matrices, xws li cov yas tshwj xeeb xws li PEEK lossis PPS, yuav raug xaiv. Cov khoom tsim nrog cov ntaub ntawv no tuaj yeem ua tiav cov cua sov siab tshaj 200 degree. Txhawm rau kom muaj cua sov ntau dua, carbon-based lossis ceramic-hlau matrices yuav tsum tau xaiv.

Hauv kev tsim cov khoom siv roj carbon fiber ntau, nws yog ib qho tseem ceeb uas yuav tsum xaiv cov chaw tsim khoom muaj npe tshwj xeeb hauv cov khoom siv fiber ntau thiab nug txog lawv cov peev xwm ua kom sov kom tau raws li cov kev xav tau tshwj xeeb. Xinhong Kev Lag Luam, nrog ntau xyoo dhau los ntawm kev tsim cov pa roj carbon fiber ntau, muaj kev txawj ntse hauv kev tsim thiab ua ntau yam khoom siv carbon fiber ntau. Lawv cov khoom ua tiav molding thiab cov tshuab ua haujlwm siab heev pab kom lawv tsim tau ntau yam ntawm cov qauv carbon fiber ntau raws li kev qhia tshwj xeeb. Xinhong cov pa roj carbon fiber ntau cov khoom lag luam tau lees paub zoo thiab tau txais kev lees paub thoob plaws ntau qhov kev lag luam. Ntawm lawv cov khoom, kev tsim cov carbon fiber rollers sawv tawm, ua rau lawv ua cov chaw tsim khoom hauv lub tebchaws. Rau txhua qhov kev nug, thov hu rau dawb.
