Koj ua kom muaj zog carbon fiber ntau?
Ua ntej, ib daim ntawv ntawm fiber ntau thiab lwm yam polymers yog rhuab mus rau qhov kub siab heev hauv qhov chaw tsis muaj oxygen. Txij li thaum tsis muaj oxygen, fiber ntau tsis tuaj yeem hlawv tab sis hloov tau kub heev uas carbon atoms yog tag nrho cov nyob.
Tom ntej no, cov pa roj carbon monoxide yog ruaj khov thiab carbonized. Qhov no cuam tshuam nrog cua sov hluav taws xob-resistant cov pa roj carbon rau qhov kub nyob rau hauv cov pa roj cua, tab sis tsis yog oxygen pup (tab sis ua noj nws txawm tias ua noj ua haus.
Thib peb, cov ntawv txias thiab raus hauv ntau yam tshuaj roj ntau, suav nrog oxygen, los muab nws zoo dua kev sib raug zoo.
Thaum kawg, tus epoxy resin txheej yog thov rau daim ntawv los tiv thaiv cov fibers los ntawm kev puas tsuaj thaum siv los ua cov khoom lag luam. Qhov sib xyaw ntawm txheej sib txawv raws cov ntaub ntawv thaum siv rau cov fiber.
Qhov no yog cov txheej txheem los ua ib daim ntawv carbon fiber ntau, uas yog ib qho khoom siv hauv tsev uas muaj zog heev tab sis tseem tuaj yeem ua tsis taus thiab yooj yim tawg rau qee qhov kev hwm. Yog xav paub ntxiv txog yuav ua li cas cov ntawv carbon fiber ntau dhau los ua tsis tiav, saib cov lus hauv qab no ntawm "Puas Carbon Fiber Break Yooj Yim?"
Nws yog ib qho tseem ceeb kom paub tias ua kom muaj zog carbon fiber yog ib qho txheej txheem nyuaj heev uas tsis tuaj yeem ua hauv tsev.
Vim li cas Carbon Fiber thiaj li muaj zog?
Carbon fiber yog ib qho ntawm cov khoom muaj zog tshaj plaws hauv ntiaj teb vim yog chainlike bonds ntawm nws cov molecules. Cov qauv no yog tsim thaum lub sij hawm tag nrho cov tshuaj tiv thaiv thiab huab cua kub hloov cov fiber mus txog thaum ua.
Cov txheej txheem khi ua ke ntau txhiab tus me me strands thiab sib tov lawv nrog epoxy. Cov Strands ua txheej txheej txheej ntawm carbon fiber, lub zog ntawm uas cuam tshuam los ntawm kev qhia meej ntawm cov strands thiab hom npuag siv hauv txheej.
Ib txheej ntawm carbon fiber yog feem ntau nyob ib ncig 0. 25mm tuab, thiab tsis muaj zog heev txhua. Qhov tseeb, ntawm qhov tuab ntawd, carbon fiber yooj yim heev rau tawg. Uas tej zaum yuav yog kev tawm tsam rau yam uas koj paub txog carbon fiber muaj zog, tab sis lub zog yog tsim muaj ntau txheej thiab xaws ntawm cov fibers, tseem hu ua "kev sib tw."
Lub molecular purity ntawm carbon fiber kuj pab nws tsim ib tug nruj kev sib raug zoo qauv.
Puas yog carbon fiber tawg yooj yim?
Cov lus teb luv luv yog tias nws tuaj yeem ua tau, raws li tau piav qhia saum toj no. Qhov zoo tshaj plaws ntawm carbon fiber yog koj tuaj yeem tswj tau lub zog thiab kev coj ntawm lub zog. Piv txwv li, yog tias koj xav kom nws muaj zog heev nyob rau hauv ib qho kev taw qhia, thiab hloov tau yooj yim dua rau lwm qhov, koj tuaj yeem ua qhov ntawd siv ib hom ntaub thiab layup.
Unidirectional Cov Ntawv
Txhawm rau piav qhia, xav txog ib qho ntawm cov ntoo mats uas siv los ua Sushi. Lub lev yog tsim los ntawm ib pawg ntawm cov ntoo uas nqaim uas khiav mus sib txuas thiab sib khi ua ke. Qhov tshwm sim yog tias nws yooj yim los khoov daim lev yog tias koj khoov tawm tsam cov noob nplej. Yog tias koj khoov nrog cov noob nplej, txawm li cas los xij, lub lev yuav tsis khoov yooj yim txhua vim tias qhov ntawd yuav txhais tau tias yog khoov tau nyuaj txaus rau snap cov pas ntoo.
Carbon fiber cov ntawv txheeb tau tsim ntawm cov pas nrig parallel, zoo ib yam li Sushi lev. Tab sis nyob rau hauv carbon fiber, cov pas nrig yog tsim los ntawm kev kho fiber ntau thiab muaj zog tshaj li ntoo. Vim tias qhov no, nws yog qhov nyuaj heev rau kev zom cov ntawv ntawm cov pa roj carbon fiber yog tias koj thov siab nyob rau hauv tib txoj kev coj ua pas nrig. Ib daim ntawv ntawm cov Rods khiav hauv ib qho kev coj zoo ib yam li cov tshuaj carbon fiber ntau cov ntaub hu ua "unidirectional," qhov twg tag nrho cov fibers khiav hauv tib txoj kev?
Tam sim no xav txog tias koj muab ob lub sushi mats ib qho rau sab saum toj ntawm lwm tus, nrog cov ntoo ntawm cov lev hauv qab mus rau ib txoj kev thiab cov pas nrig ntawm cov lev saum toj kawg nkaus khiav mus rau lwm txoj kev. Tam sim no, cov mats txhawb ib leeg thiab kom ib leeg tsis txhob khoov rau hauv ob qho tib si.
Nrog unidirectional carbon fiber, thaum koj muab cov khaubncaws sab nraud povtseg ntawm cov khoom, koj tuaj yeem tswj cov kev taw qhia ntawm lub zog nrog txhua txheej. Qhov kev tswj ntawm lub zog kev taw qhia no yog ib qho ntawm cov txiaj ntsig ntawm carbon fiber. Siv ntau cov khaubncaws sab nraud povtseg, koj tuaj yeem ua cov khoom kawg kom muaj zog raws li koj xav tau rau daim ntawv thov.
Woven Daim Ntawv
Hauv cov ntawv sau cia ntawm cov fiber carbon fiber, cov filaments yog woven ua ke zoo li cov strands ntawm lub pob tawb los tuav ua ke zoo dua. Muaj ntau hom sib txawv ntawm weaves uas tau siv rau ntau vim li cas ntau yam. Nws tuaj yeem ua kom zoo nkauj, lossis nws tuaj yeem yooj yim dua los ua haujlwm ib hom khoom siv rau hauv pwm, thiab nws yuav muaj zog ntau hauv ntau cov lus qhia. Hom ntaub tau siv thiab cov kev taw qhia uas lawv tau muab tso rau tswj lub zog, yog txhua feem ntawm kev txhim kho cov phiaj xwm kev sib tw.
Txawm li cas los xij, txawm li cas los xij, ib daim ntawv ntawm cov ntaub fiber ntau tseem yuav tsis muaj zog tshwj tsis yog tias lawv tau txheej.
Cov khoom siv ntawm cov pa roj carbon fiber ntau (txawm yog woven lossis unidirectional) nrog rau kev hloov pauv ntawm cov hlau, qhov tseeb.
Koj tuaj yeem hlawv cov fiber carbon fiber ntau?
Koj yuav muaj lub sijhawm nyuaj hlawv carbon fiber.
Yog tias koj kub nws mus txog 750 degrees, nws yuav kub hnyiab heev kom ntev li ntev tau siv cov roj hlawv rau nws. Tab sis txawm nyob rau ntawm lub sijhawm ntawd, qhov hluav taws kub yuav nres sai li sai tau thaum lub qhov hluav taws xob raug tshem tawm.
Qhov kev txwv tsis pub hlawv yog tshwm sim los ntawm cov resin ua ke nrog cov pa roj carbon fiber ntau, vim tias carbon nws tus kheej yuav tsis hlawv. Tsuas yog vim li cas cov fiber ntau hlawv yog vim tias cov khoom tsis yog carbon nyob rau hauv nws yuav hlawv.
Muaj ntau hom resin uas tuaj yeem txhawb nqa ntau hom cua sov. Ib qho epoxy resin yog qhov zoo txog li ntawm 200 degrees Fahrenheit, tab sis cov khoom kub kub feem ntau yuav tiv taus cua sov txog 400 degrees. Nco ntsoov xyuas cov specifications ntawm cov resin siv.
Vim tias cov pa roj carbon fiber yog li kev tiv thaiv tshav kub tab sis tseem muaj zog, nws yog siv rau hauv cov ntawv thov enginalering zoo li cov tog sab hauv.
Puas tuaj yeem carbon fiber ntau xeb?
Tsis yog. Cov ntawv cog lus nruj hauv cov pa roj carbon fiber ntau tiv thaiv oxidation vim yog cov txheej txheem tshuaj lom neeg siv thaum tsim khoom. Cov epoxy resins siv los tiv thaiv cov carbon fiber los ntawm kev puas tsuaj yog inert, txhais tau tias nws muaj kev ruaj ntseg los ntawm xeb thiab lwm yam corrosion.
Muaj zog npaum li cas Carbon Fiber Filament?
Cov pa roj carbon fiber ntau yog cov hlua ib leeg siv rau ntawm cov ntaub ntawv carbon fiber. Cov strands feem ntau yog sib koom ua ke siv cov cob, uas yog RP hauv CFRP (carbon fiber reinforced yas). Los ntawm kev sib koom ua ke cov khoom siv rau cov pa roj carbon fiber ntau cov tshuaj muaj pes tsawg leeg, engineers tuaj yeem tsim ib yam dab tsi ntau ruaj, muaj zog, thiab sib zog dua nws qhov chaw.
Hauv cov ntaub npuag, txhua txoj hlua ntawm cov roj carbon fiber yuav ib txwm muaj qhov nruab nrab ntawm 1, 000 thiab 12, 000 ib leeg filaments, tsawg dua qhov dav ntawm tib neeg cov plaub hau.
Yog li cas muaj zog carbon fiber? Cia li muab tso rau hauv no: tsis muaj ntau cov ntaub ntawv nyob rau hauv lub ntiaj teb no muaj zog tshaj carbon fiber -- tshwj xeeb tshaj yog tsis muaj nyob rau hauv lub lag luam.
