Carbon fiber yog dab tsi?

Cov pa roj carbon fiber (tseem hu ua carbon fiber) yog ib qho ntawm cov khoom muaj zog tshaj plaws thiab lub teeb tshaj plaws ntawm kev ua lag luam niaj hnub no. Cov pa roj carbon fiber ntau yog tsib zaug muaj zog thiab ib feem peb ntawm qhov hnyav ntawm cov hlau thiab feem ntau siv hauv aerospace, neeg hlau, kev sib tw thiab ntau yam kev lag luam.

 

ntaub
Cov pa roj carbon fiber ntau pib tawm raws li cov fibers nyias nyias, nyias dua li tib neeg cov plaub hau. Cov hlua no tau sib tw ua ke zoo li cov xov paj (hu ua cov hlua) thiab woven rau hauv cov ntaub ntawv carbon fiber, feem ntau muaj nyob rau hauv 3k, 6k, thiab 12k qhov hnyav. 3k ntaub muaj 3,000 strands ntawm carbon ib tug cab, thaum lub hnyav 6k ntaub muaj 6,000 strands ntawm carbon ib tug cab.

Cov ntaub yog muaj nyob rau hauv ntau yam weaves nrog txawv zog zog. Feem ntau cov feem ntau yog tiaj weave, heddle weave, twill weave thiab unidirectional weave.

Braiding yog qhov tseem ceeb rau ob qho laj thawj: tsos thiab ua haujlwm. Txhua cov ntaub so ntswg zoo li txawv heev, thiab qee zaum tib neeg nyiam qhov zoo ntawm cov ntaub so ntswg rau ib daim ntawv thov tshwj xeeb. Weaving kuj cuam tshuam cov khoom muaj zog.

Unidirectional weaving tsim ib daim ntawv uas muaj zog heev nyob rau hauv cov kev taw qhia fiber ntau tab sis tsis muaj zog nyob rau hauv qhov kev taw qhia. Plain thiab twill fabrics, ntawm qhov tod tes, muaj lub zog zoo dua vim tias lawv muaj zog tshaj plaws ntawm cov ntsiab lus uas cov fibers hla mus rau ob qho tib si.

cov ntaub ntawv sib xyaw
Ua cov panels, tseem hu ua composites, carbon fiber ntaub yog dipped los yog infused nrog epoxy resin thiab rhuab ntawm high kub. Mouldings yog tsim los ntawm kev tso cov ntaub ntawm cov pwm, saturating lawv nrog resin, thiab tom qab ntawd cua sov kom txog thaum cov resin nkag mus rau txhua txheej.

Qhov zoo ntawm carbon fiber
Cov pa roj carbon fiber ntau sawv tawm rau ntau qhov laj thawj. Nov yog qee qhov:

Lub teeb yuag - nws yog cov khoom siv tsis tshua muaj siab nrog lub zog siab heev rau qhov hnyav piv
Lub zog tensile siab - Cov pa roj carbon fiber yog ib qho ntawm qhov muaj zog tensile lub zog ntawm tag nrho cov khoom lag luam muaj zog ntxiv thiab nws nyuaj rau ncab lossis khoov vim nws lub zog tensile kawg.
Tsawg Thermal Expansion - Nws nthuav tawm lossis cog lus tsawg dua hauv qhov kub lossis txias dua li cov ntaub ntawv xws li hlau thiab txhuas
Zoo heev durability - nrog
Cov pa roj carbon fiber ntau muaj qhov ua kom qaug zog zoo dua piv rau cov hlau, lub ntsiab lus ua los ntawm carbon fiber yuav tsis hnav sai li sai tau raws li kev ntxhov siab ntawm kev siv txuas ntxiv.
Corrosion Resistant - Thaum tsim los ntawm cov khoom tsim nyog, nws yog ib qho ntawm cov khoom siv tiv thaiv corrosion tshaj plaws
Radiolucency - Carbon fiber yog pob tshab rau hluav taws xob thiab pom tsis pom hauv X-rays, ua rau nws muaj txiaj ntsig rau kev siv hauv cov cuab yeej kho mob thiab cov chaw.
conductivity --
Cov pa roj carbon fiber ntau yog cov khoom siv hluav taws xob zoo heev
UV tiv taus - los ntawm kev siv tsim nyog
Resin, carbon fiber tuaj yeem tiv taus UV rays
ua tsis tau
Cov pa roj carbon fibers tuaj yeem tawg lossis tawg thaum lawv raug compressed, tshaj lawv lub peev xwm muaj zog, lossis raug kev cuam tshuam loj. Yog koj ntaus nws nrog rauj nws yuav tawg. Machining thiab qhov tuaj yeem tsim qhov chaw tsis muaj zog, ua rau muaj qhov ua rau nws tawg.
Tus nqi txheeb ze - Carbon fiber yog cov khoom siv zoo nrog tus nqi kom phim. txawm tias
Cov nqi tau poob qis dua tsib xyoos dhau los, tab sis kev thov tsis tau nce txaus
Txhawb nqa ntau ntxiv. Yog li ntawd, tus nqi
Qhov no yuav zoo li tsis hloov pauv yav tom ntej.
