Nws paub zoo tias carbon fiber yog ib yam tshiab ntawm cov khoom siv fiber ntau nrog lub zog siab thiab siab modulus, muaj ntau dua 95% carbon.Nws muaj cov yam ntxwv ntawm "Mos rau sab nraud tab sis nruj rau sab hauv", lub plhaub yog tawv thiab cov khoom siv fiber ntau yog mos.Nws yog sib dua li txhuas, tab sis muaj zog dua hlau, nrog corrosion kuj, siab modulus yam ntxwv.Lub npe hu ua "Cov khoom siv tshiab", tseem hu ua "Dub Kub", yog lub cim tshiab ntawm cov fibers ntxiv.
Cov no yog tag nrho cov kev paub superficial ntawm science.Muaj pes tsawg tus neeg paub txog carbon fiber?
1. Carbon fiber ntaub
Los ntawm cov ntaub ntawv yooj yim carbon fiber ntau, carbon fiber yog nyias nyias.Nws yog hais txog tib yam li cov plaub hau, tab sis nws zoo dua cov plaub hau, nws yog ntau pua lub sij hawm me me, tab sis yog tias koj xav ua cov khoom tawm ntawm cov roj carbon fiber, koj yuav tsum tau weave rau hauv ib daim ntaub, thiab muab tso rau saum. ntawm nws, txheej los ntawm txheej, thiab qhov ntawd yog hu ua daim ntaub carbon fiber.
2. Unidirectional ntaub
Carbon fiber bundles, ib-txoj kev ntaub los ntawm tib cov kev taw qhia los ntawm cov carbon fiber array.Cov neeg siv tau hais tias kev siv cov ntaub ntawv carbon fiber ib leeg tsis zoo.Nws tsuas yog kev npaj, tsis yog qhov loj ntawm cov pa roj carbon fiber ntau.
Vim tias daim ntaub unidirectional tsis zoo nkauj, zoo li marble lis.
Cov pa roj carbon fiber tam sim no nyob rau hauv kev ua lag luam yog marble, tab sis ob peb tus neeg paub tias nws los ua li cas.Nws yog qhov yooj yim li kev noj cov pa roj carbon fiber ntau rau saum npoo, txheej nrog cov resin, nqus nws, thiab muab cov khoom ua ke los ua cov kab carbon fiber.
3. Ntaub ntaub
Woven fabrics feem ntau hu ua 1K, 3K, thiab 12K carbon fibers.1K yog 1,000 daim ntawm carbon fiber uas yog woven ua ke.Nws tsis yog hais txog carbon fiber, nws yog hais txog qhov zoo.
4. Resin
Cov resin yog siv los coated carbon fiber.Yog tsis muaj cov resin coated carbon fiber, nws yog mos, 3,000 carbon fibers tawg nyob rau hauv ib tug rub, tab sis coated nrog cob, cov pa roj carbon fiber yog nyuaj tshaj hlau thiab muaj zog tshaj hlau.Roj txheej kuj tseem tshwj xeeb tshaj, ib qho hu ua Preg, ib qho hu ua kev cai lij choj.Pre-impregnation yuav ua ntej txheej txheej ua ntej siv cov pa roj carbon pwm;txoj hauv kev yog siv nws li koj xav tau.Lub prepreg yuav tsum tau khaws cia ntawm qhov kub thiab txias thiab kho ntawm qhov kub thiab txias, kom cov pa roj carbon fiber ntau yuav muaj zog.Hauv kev siv txoj cai lij choj, cov resin thiab curing tus neeg sawv cev yog sib xyaw, coated rau ntawm daim ntaub carbon, nias ua ke, tom qab ntawd lub tshuab nqus tsev qhuav thiab sab laug rau ob peb teev.
