Nkag Siab Cfrp Composites

- Lub peev xwm amazing ntawm carbon fiber ntxiv txhawb polymers.

Carbon FiberSiv cov tshuaj sib xyaw Polymer (CFRP) yog lub teeb ci, cov ntaub ntawv muaj zog siv nyob rau hauv kev tsim cov khoom siv ntau ntau cov khoom siv hauv peb lub neej. Nws yog ib lo lus siv los piav txog kev txhawb nqa fiber ntau ntxivCov Khoom Siv Compositeuas siv carbon fiber raws li cov txheej txheem thawj. Nws yuav tsum raug sau tseg tias "P" hauv CFRP tseem tuaj yeem sawv ntsug rau "yas" tsis yog "polymer."

Feem ntau, CFRP cov pa sib xyaw siv thermosetting los xws li epoxy,Polyester, lossis Vinyl EsterCov. Txawm yogThermoplastic ResinsYog siv hauv CFRP cov nyiaj sib xyaw, "Carbon Fiber txhawb Thermoplastic Composites" feem ntau mus los ntawm lawv tus kheej acronymites, CFTTr Composites.

Thaum ua haujlwm nrog kev sib xyaw lossis hauv kev sib xyaw kev lag luam, nws yog ib qho tseem ceeb kom nkag siab cov lus thiab cov ntawv sau. Tseem ceeb tshaj, nws yog ib qho tsim nyog kom nkag siab txogCov khoom ntawm Frp Compositesthiab lub peev xwm ntawm cov kev txhawb ntau yam xws li carbon fiber.

Cov khoom ntawm CFRP kev sib xyaw

Composite cov ntaub ntawv, txhawb nqa nrog carbon fiber, muaj sib txawv dua li lwm tus frp composites siv cov ntaub ntawv ib txwm siv xws li fiberglass lossisArabid FiberCov. Cov yam ntxwv ntawm CFRP cov pa sib xyaw uas muaj txiaj ntsig zoo li:

Lub teeb hnyav:Ib txwm muajFiberglass txhawb cov tshuaj sib xyawSiv cov iav fiber ntau nrog cov fiber ntau ntawm 70% iav (qhov hnyav ntawm iav / tag nrho cov iav / tag nrho cov iav / tag nrho muaj qhov ntom ntawm .065 phaus ib qho cubic.

Lub caij no,

Ua kom muaj zog:Tsis yog tsuas yog carbon fiber ntau composites hnyav, tab sis cfrp sib dhos muaj zog ntau dua thiab stifer ib chav ntawm qhov hnyav. Qhov no muaj tseeb thaum sib piv cov pa roj carbon fiber ntau rau cov iav fiber ntau, tab sis txawm ntau dua li thaum piv cov hlau.

Piv txwv li, txoj cai tsim nyog ntawm tus ntiv tes xoo thaum sib piv cov hlau mus rau CFRP cov hlua yog tias cov qauv roj carbon fiber ntau dua 1 / 5th uas ntawm cov hlau. Koj tuaj yeem xav txog vim li cas cov tuam txhab tsheb tau tshawb xyuas siv cov roj carbon fiber es tsis txhob siv hlau.

Thaum muab piv rau CFRP sib xyaw rau txhuas, yog ib qho ntawm cov qauv teeb pom kev zoo, cov qauv txhuas yog tias muaj lub zog txhuas yuav hnyav 1.5 zaug ntawm tus qauv carbon fiber.

Ntawm chav kawm, muaj ntau yam hloov uas tuaj yeem hloov qhov kev sib piv no. Cov qhab-nees thiab cov ntaub ntawv zoo tuaj yeem sib txawv, thiab cov khoom sib xyaw nrog covCov txheej txheem tsim khoom, cov cuab yeej siv fiber ntau, thiab qhov zoo xav tau coj mus rau hauv tus account.

Qhov tsis zoo ntawm CFRP sib xyaw

Nqi:Txawm hais tias cov khoom siv zoo heev, muaj ib qho laj thawj yog vim li cas carbon fiber tsis siv rau txhua daim ntawv thov. Thaum lub sijhawm, kev sib xyaw CFRP yog them nqi rau ntau zaus. Nyob ntawm cov kev ua lag luam tam sim no (muab khoom siv thiab xav tau), cov nqi ntawm cov phuam loj), thiab cov nqi ntawm cov fiber ntau tuaj yeem sib txawv.

Cov roj carbon fiber ntawm cov nqi-per-phaus hauv paus tuaj yeem nyob txhua qhov chaw ntawm 5-zaug rau 25-zaug ntau dua cov nqi fiberglass. Qhov kev sib cav no tseem ceeb tshaj thaum sib piv cov hlau mus rau CFRP cov khoom sib xyaw.

Conductivity:Qhov no tuaj yeem yog ob qho tib si zoo rau cov roj carbon fiber ntau, lossis qhov tsis zoo nyob ntawm daim ntawv thov. Carbon fiber yog cov ua tau zoo heev, thaum lub khob iav fiber yog cov insulative. CoobCov ntawv thov siv cov iav fiber, thiab tsis tuaj yeem siv cov roj carbon fiber lossis hlau, nruj me ntsis vim tias qhov kev coj ua.

Piv txwv li, hauv kev lag luam hluav taws xob, ntau cov khoom lag luam yog yuav tsum tau siv iav fibers. Nws tseem yog ib qho ntawm cov laj thawj yog vim li cas cov tub ntaiv siv khob fiber ntau li tus ntaiv ntaiv. Yog hais tias tus ntaiv fiberglass tau tuaj ntsib nrog lub hwj huam sib luag, txoj kev muaj feem ntawm hluav taws xob yog qhov qis dua. Qhov no yuav tsis yog qhov xwm txheej nrog CFR cov ntaiv.

Txawm hais tias tus nqi ntawm CFRP cov khoom sib xyaw tseem nyob twj ywm, kev nce qib tshiab hauv kev tsim tau txuas ntxiv kom muaj cov khoom siv nqi ntxiv. Vam tias, nyob rau hauv peb lub neej, peb yuav tuaj yeem pom cov roj carbon fiber siv nyob rau hauv ntau cov neeg siv khoom, kev lag luam, thiab cov ntawv thov siv tsheb.
