Kev tsim kho cov txheej txheem ntawm cov ntaub pua fa roj carbon fiber ntau

 

Carbon fiber ntau siv nyob rau hauv aerospace, tsheb, ntaus pob ncaws pob thiab lub zog zoo heev xws li lub zog siab, lub teeb yuag thiab corrosion tsis kam. Nws cov txheej txheem tsim tau yog qhov sib txawv thiab yuav tsum muaj cov ntxaij ntawm cov thev naus laus zis thiab khoom siv tshwj xeeb. Cov hauv qab no yog cov txheej txheem tsim khoom loj ntawm cov ntaub pua fa carbon fiber:

1. Fiber npaj

Kev tsim cov khoom siv roj carbon fiber ntau pib nrog kev npaj ntawm carbon fiber. Polyacrylonitrile (yias) lossis cov pa roj carbon fiber ntau precoator fiburs feem ntau yog siv los ua cov ntaub ntawv raw. Cov fibers tau ua tiav los ntawm kev kos duab, cua sov thiab oxidation los ua cov high-zog thiab high-modulus carbon fiber.

2. Tab tom hlab thiab lamination

Kev tsim cov khoom siv fiber ntau tuaj yeem weaving carbon fiber ntau yarns rau hauv cov ntaub. Qhov no tuaj yeem ua tiav los ntawm kev sib txawv ntawm weaving (xws li lub ntsej muag dawb, twill, hollow weave, thiab lwm yam) kom ua tiav kev ua tau zoo thiab yam ntxwv zoo. Tom qab nws tab tom, ntau txheej ntawm carbon fiber ntau ntaub tuaj yeem ua ke kom ua kom muaj zog thiab tawv tawv.

3. Resin Impregnation

Txhawm rau ua kom muaj zog ntxiv ntawm cov carbon fiber thiab tiv thaiv cov ntaub pua fiber ntau, carbon fiber feem ntau yog impregnated nrog resin. Cov txheej txheem no hu ua Resin Impregnation lossis Impregnation. Feem ntau siv cov resins suav nrog epoxy cob, polyester Resin thiab Phenumed Resin. Tom qab Impregnation, cov ntaub pua fa carbon fiber ntau yog kho los ua cov khoom siv sib xyaw ua ke.

4. Kub Nias

Tom qab Impregnation thiab kho, cov ntaub fiber ntau cov ntaub rau cov duab zaum kawg los ntawm cov xovxwm kub. Thaum lub sij hawm cov xovxwm kub kub Moulding txheej, cov ntaub pua carbon fiber tau muab tso rau hauv tshav kub kub thiab siab kho cov cob qhia thiab sib txuas nrog cov fibers los ua qhov kawg lossis ib feem.

5. Txiav Thiab Ua

Tom qab kub xovxwm moulding, cov ntaub fiber ntau cov ntaub ua tau thiab ua tiav. Qhov no tuaj yeem siv cov cuab yeej txiav (xws li riam los yog lasers) kom raug txiav cov tshuaj fiber ntau cov ntaub kom tau txais cov duab uas xav tau thiab qhov loj me. Ib qho ntxiv, kev ua haujlwm xws li drilling, xuas nrig, xuas nrig ntaus, sib tsoo, thiab lwm yam tuaj yeem ua tau.

Lub ntsiab

Kev tsim khoom thiab kev ua cov ntaub pua fiber ntau yog cov txheej txheem nyuaj uas yuav tsum muaj qib siab thiab khoom siv. Cov neeg ua haujlwm yuav tsum nkag siab cov khoom siv, cov txheej txheem tsis sib xws thiab kev ua haujlwm tshwj xeeb los xyuas kom zoo thiab ua tau zoo ntawm cov khoom kawg. Yog li ntawd, rau cov teeb meem loj loj lossis cov kws tshaj lij uas ua cov tshuaj fiber ntau, lawv ib txwm muaj kev tshaj lij thiab kev paub dhau los.
