Qhov kub siab npaum li cas tuaj yeem carbon fiber tiv taus
Cov pa roj carbon fiber nws tus kheej muaj qhov kub thiab txias heev, thiab nws tuaj yeem hais tau tias yog cov khoom siv kub kub resistant, tab sis cov ntaub ntawv carbon fiber ntau nyob ntawm cov khoom siv matrix.
Yan F cone rho cov ntaub ntawv raw los ntawm roj av thiab thee.Ua ntej, polyacrylonitrile yog muab rho tawm, thiab ces carbon fiber yog muab rho tawm los ntawm polyacrylonitrile.Cov kev cai ntawm no yog siab heev, thiab oxidation, carbonization thiab graphitization nyob rau hauv tag nrho cov txheej txheem yog tag nrho nws xav tau kub kub kom tiav, tshwj xeeb tshaj yog nyob rau hauv lub kub kub ntawm ob peb txhiab degrees ntawm pob zeb quarrying, tom qab tshem tawm cov ntawv xov xwm, cov pa roj carbon fiber cab tau txais, yog li cov pa roj carbon fiber nws tus kheej muaj qhov kub thiab txias tsis kam, tuaj yeem tiv taus qhov kub thiab txias ntawm 3000 ℃, thiab tuaj yeem tswj tau qhov kev ua tau zoo.
Vim li cas ntau cov khoom siv carbon fiber ntau tsis tiv taus qhov kub thiab txias?
Raws li tau hais los saum no, carbon fiber muaj qhov zoo thiab kub tsis kam.Hauv kev tsim cov khoom lag luam carbon fiber, nws tsis yog tsuas yog cov khoom siv carbon fiber.Cov khoom siv matrix kuj yuav tsum tau ua kom tiav cov khoom siv fiber ntau lig.Cov khoom siv carbon fiber ntau tiv taus qhov kub thiab txias.Xav txog qhov kub tsis kam ntawm cov khoom siv hauv paus.
Qhov tseeb tias ntau cov khoom siv fiber ntau tsis wrinkle thiab kub yog vim cov khoom siv fiber ntau feem ntau yog carbon fiber + resin-raws li cov ntaub ntawv sib xyaw, thiab cov ntsiab lus ntawm cov fiber ntau cab hauv cov khoom sib xyaw yog li 40% -45%, yog li ntau lawm Lub siab kub tsis kam ntawm cov khoom tiav carbon fiber ntau muaj feem xyuam rau qhov kub kub tsis kam ntawm cov resin.Qhov no zoo li lub hauv paus ntsiab lus ntawm cov ntoo chim.Lub siab kub tsis kam txwv ntawm resin tau dhau los ua qhov txwv siab ntawm kev kub siab ua haujlwm ntawm cov khoom siv fiber ntau.
Nyob rau hauv ib txwm muaj xwm txheej, qhov kub tsis kam ntawm resin matrix yog li 180C.Yog tias nws siab tshaj qhov kub ntawm lub sijhawm ntev, nws yuav ua rau cov resin matrix yaj, uas yuav cuam tshuam rau qhov kawg ntawm cov khoom.
Tsis tas li ntawd, txhawm rau txhawm rau txhawm rau txhim kho qhov kub thiab txias, tsob ntoo ntiv tes hauv paus yuav xaiv cov matrix uas muaj qhov kub thiab txias, uas yog, tshwj xeeb yas.Yog tias koj muaj cov khoom siv matrix uas muaj kev ua tau zoo dua qub xws li PEK thiab PPS, cov khoom siv carbon fiber ntau uas tsim tawm yuav tiv taus qhov kub siab tshaj 20YC.Yog tias yuav tsum tau ua kom sov siab dua, yuav tsum tau xaiv carbon-based lossis ceramic hlau matrix.Xws li kub kub kuj yuav ua tau zoo dua.
