Cov pa roj carbon fiber ntau yog ua los ntawm cov khoom siv carbon fiber ntau, yog li kev ua haujlwm ntawm tag nrho cov pa roj carbon fiber ntau yog sib cais los ntawm cov khoom siv carbon fiber ntau. Cov pa roj carbon fiber ntau yog tsim los ntawm cov ntsiab lus carbon, thiab cov qauv sab hauv zoo ib yam li cov khoom siv graphite. Cov pa roj carbon atoms txuas ua ke hauv daim ntawv ntawm graphitized hexagonal microcrystals, tsim ib qho kev tsis sib haum xeeb graphite qauv thiab taw qhia raws axial kev taw qhia ntawm carbon fiber. Qhov kev taw qhia crystalline no ua rau cov pa roj carbon fiber ntau muaj zog thiab zoo txhua yam khoom.
Yog li yuav ua li cas thiaj li ua tau zoo ntawm cov kav dej carbon fiber ntau tuaj yeem lav tau?
1. Xaiv cov khoom pwm tsim nyog
Rau filament winding los yog yob-pob txheej txheem, vim hais tias cov fiber ntau raug mob nyob rau hauv ib tug compressive quab yuam, nws cov duab sib sau ua ke tseem tsis tau hloov. Yog li ntawd, nws yog qhov zoo dua los siv cov ntaub ntawv hlau nrog zoo rigidity li cov tub ntxhais pwm, xws li steel thiab duralumin. Qhov ntom thiab hardness ntawm hlau yog siab dua li ntawm duralumin, tab sis lub thermal expansion coefficient ntawm hlau tsis zoo li cov duralumin. Cov pa roj carbon fiber ntau ua haujlwm zoo yog kho thaum kub kub. Yog tias xaiv duralumin mandrel ua cov pwm tseem ceeb, qhov ntom ntom thiab cov khoom siv kho tshuab ntawm cov yeeb nkab carbon tuaj yeem txhim kho los ntawm kev kub siab kho los ntawm thermal expansion ntawm hard aluminium.
2. Kev tswj qhov kub thiab txias nrog pre compaction
Ib kauj ruam tseem ceeb hauv kev daws qhov teeb meem ntawm qhov chaw ntawm cov kav dej carbon fiber yog los ua ke ua ntej kev sib cog lus thiab kev tswj qhov kub thiab txias thaum lub sij hawm tso txheej txheem. Lub luag haujlwm tseem ceeb yog ua ntej compact txhua txheej ntawm qhov kub thiab txias thaum lub sij hawm tso, thiab siv qee qhov siab los ua kom txhua txheej ntawm fibers.
Pre compaction tuaj yeem tiv thaiv kev sib sau ntawm cov khaubncaws sab nraud povtseg. Nyob rau hauv ib tug tej yam siab thiab kub, ntau resin, huab cua npuas, thiab tsawg boiling tshuaj raug tshem tawm los ntawm lub prepreg dawb paug, ua rau lub dawb paug compact thiab yeej mus txog lub predetermined thickness. Lub pre-compacted dawb paug yuav tsis nqus cov kua nplaum thaum kho. Tom qab cov kauj ruam no, cov ntsiab lus resin nyob rau hauv cov khoom siv carbon fiber ntau thiab cov tuab ntawm cov yeeb nkab tuaj yeem tswj tau zoo.
3. Thaum tshav kub kub shrinking txheej txheem
Ntxiv nrog rau cov txheej txheem saum toj no, cov txheej txheem kub hnyiab tuaj yeem siv los txhim kho qhov zoo ntawm qhov chaw thiab kev tsim khoom raug ntawm cov kav dej carbon fiber. Thaum lub sij hawm kub-kub kho, cov khoom siv cua sov-shrinkable tuaj yeem cuam tshuam lub siab ntawm lub autoclave, thiab tshem tawm cov kev cuam tshuam ntawm wrinkles ntawm lub hnab nqus tsev vacuum thiab breathable xav ntawm cov khoom sib xyaw. Thaum xaiv cov ntaub ntawv kub hnyiab, ntau qhov ntev xws li shrinkage kub, shrinkage tus nqi, thiab kub tsis kam yuav tsum tau txiav txim siab.
Runfeng yog ib lub tuam txhab nrog ntau tshaj kaum xyoo ntawm kev paub nyob rau hauv lub tshav pob ntawm carbon fiber ntau lawm thiab ua. Nws muaj ib pab neeg ua haujlwm paub txog, ua tiav cov khoom siv carbon fiber ntau ntau lawm, thiab nruj me ntsis tswj ntawm txhua kauj ruam ntawm cov txheej txheem ntau lawm. Pls tiv tauj peb yog tias koj xav tau cov khoom siv carbon fiber ntau.
