Dab tsi yog carbon fiber composite?
Cov pa roj carbon fiber ntau yog cov khoom siv ntev thiab nyias nyias nrog txoj kab uas hla ntawm 0.0002 txog 0.0004 ntiv tes (0.005-0.010 mm), feem ntau yog tsim los ntawm carbon atoms. Lub zog carbon fiber ntau yog 10 npaug zog dua hlau, 8 npaug zog dua aluminium, thiab ntau dua li ob cov ntaub ntawv, 5 zaug thiab 1.5 npaug ntawm qhov sib npaug. Tsis tas li ntawd, lawv cov khoom qaug zog yog qhov zoo tshaj plaws rau tag nrho cov qauv hlau paub, thiab thaum ua ke nrog cov khoom tsim nyog, lawv yog ib qho ntawm cov khoom siv corrosion-resistant tshaj plaws.
Raws li cov khoom sib txawv, carbon fiber tuaj yeem muab faib ua peb pawg. Lub ntiaj teb no tuaj yeem ua tiav kev tsim khoom lag luam feem ntau suav nrog polymerization (PAN)-raws li carbon fiber, pitch-based carbon fiber thiab viscose-based carbon fiber. Ntawm lawv, PAN-raws li carbon fiber nyob rau feem ntau kiag li. Raws li txoj cai, nrog ib feem ntawm ntau tshaj 90%, ua raws li cov pa roj carbon fiber ntau accounting txog li 6-8%, thiab viscose-based carbon fiber ntau lawm yog qhov qis tshaj.
Los ntawm qhov kev xav ntawm daim ntawv thov kev lag luam, qhov kev thov rau cov ntawv thov classic xws li aerospace, cov cuab yeej ua kis las, tsheb, kev txhim kho lub tsev, thiab molding compounding tseem muaj zog, thiab cov chaw tawm tshiab xws li cua zog thiab cov hlab ntsha siab tau dhau los ua lwm lub cav tseem ceeb tsav kev lag luam. . Ntawm lawv, cua zog thiab aerospace suav txog ze li ib nrab, ua raws li kev ua si thiab kev lom zem thiab kev lag luam tsheb.

Ntiaj teb no thiab Suav carbon fiber composite cov ntaub ntawv kev loj hlob thiab thaum ntxov theem ntawm kev loj hlob:

Xyoo 1860, Joseph Swann tau tsim cov pa roj carbon fiber ntau thawj zaug hauv qhov muag teev.
Xyoo 1879, Thomas Edison ci paj rwb xov lossis xyoob strips ntawm qhov kub thiab txias thiab carbonized rau hauv cov pa roj carbon fiber ntau, uas tau siv rau hauv ib qho ntawm thawj qhov muag teev thiab cua sov nrog hluav taws xob.
Xyoo 1958, Roger Bacon tau tsim cov pa roj carbon fiber ntau ntawm Union Carbide Par-ma Technology Center sab nraum Cleveland, Ohio. Cov fibers no yog tsim los ntawm cua sov rayon xov kom txog thaum lawv tau carbonized. Tom qab qhov tseeb tau ua pov thawj tias txoj kev no tsis muaj txiaj ntsig vim tias cov txiaj ntsig carbon fiber tsuas muaj li ntawm 20% carbon thiab muaj zog thiab nruj zog.
Nyob rau xyoo 1960, kev sim ua haujlwm nrhiav lwm cov ntaub ntawv raw coj mus rau kev qhia txog cov khoom siv carbon fiber ntau ua los ntawm cov roj av tau los ntawm kev ua roj av. Cov fibers no muaj txog 85% carbon thiab muaj zog tensile zoo heev. Tsis tas li ntawd, lub sijhawm no, tsoomfwv Nyij Pooj tau txhawb nqa kev txhim kho ntawm cov pa roj carbon fiber hauv tsev, thiab ntau lub tuam txhab Nyij Pooj xws li Toray, Teijin thiab Mitsubishi tau pib lawv tus kheej txoj kev loj hlob thiab tsim khoom.
Txij li thaum xyoo 1970s lig, ntau hom carbon fiber yarns tau nkag mus rau hauv lub lag luam thoob ntiaj teb, muab lub zog tensile ntau dua thiab ntau dua modulus ntawm elasticity. Piv txwv li, lub zog tensile ntawm T400 yog 4,000MPa, thiab modulus yog 400GPa. Intermediate carbon fibers tau tsim, xws li IM 600 nrog rau 6,000MPa. Cov ntaub ntawv carbon fiber ntau tau siv thawj zaug hauv kev siv dav hlau los ntawm theem nrab mus rau cov khoom tseem ceeb hauv cov tub rog thiab tom qab dav hlau dav hlau, xws li dav hlau los ntawm McDonald Douglas, Boeing, Airbus thiab United Aircraft Corporation.

Tuam Tshoj tus carbon fiber kev loj hlob keeb kwm:
Thaum xyoo 1970, txhawm rau ua kom tau raws li qhov xav tau ntawm kev tiv thaiv hauv tebchaws, Lub Tsev Haujlwm ntawm Chemistry ntawm Suav Academy ntawm Kev Tshawb Fawb tau xa qee cov kws tshawb fawb los ntawm Polymer Physics Laboratory thiab Special Polymer Materials Laboratory los tsim cov pab pawg 803 thiab 804, tsom mus rau "kev npaj txuas ntxiv ntawm. carbon fibers" thiab "shortening ntawm carbon fiber npaj cycles." Kev tshawb fawb" thiab ua tiav "stannic chloride" catalysis thiab lwm yam txiaj ntsig.
Xyoo 1972, Jilin Research Institute of Chemical Industry ntawm Ministry of Chemical Industry tau tsim cov txheej txheem nitric acid los tsim cov pa roj carbon fiber ntau PAN precursors, thiab tau txais cov nitric acid ib-kauj ruam txoj kev los npaj cov precursors ntawm 3 tons txhua xyoo tso zis ntaus ntawv rau lub Kev tshawb fawb ntawm carbon fiber los ntawm Shanxi Combustion thiab Chemical Institute thiab Changchun Institute of Applied Chemistry. Shanxi Combustion thiab Chemical Company tau ua qhov kev tshawb fawb tsis ncaj ncees ua ntej oxidation thiab carbonization, thiab ua tiav kev kuaj ua ntej oxidation thiab carbonization.
Los ntawm 1975 mus rau 1990, txawv teb chaws carbon fiber nkag mus rau ib theem ntawm kev loj hlob sai, tab sis domestically, nws tsuas pom tau hais tias tsis muaj cov khoom, thiab nws tsis muaj peev xwm tsim nyob rau hauv loj scale.
Muaj peev xwm nkag mus rau theem ntawm kev loj hlob sai hauv xyoo 2007; Tam sim no muaj ze li ntawm 30 lub tuam txhab hauv tebchaws, tab sis lawv feem ntau yog me me. Feem ntau ntawm cov tuam txhab 'ib kab nominal muaj peev xwm tsuas yog 1,000 tons, thiab ntau ntawm lawv tsuas yog nyob rau theem 100-tuj, kaum tawm tons, thiab nyob deb. deb ntawm kev ncav cuag qhov ntsuas ntawm kev ua lag luam daim ntawv thov.

Carbon fiber ntau txhim kho lub sijhawm:
Lub ntiaj teb kev kub ntxhov nyiaj txiag tau tshwm sim hauv ib nrab xyoo 2008, kev lag luam tiag tiag tau cuam tshuam loj heev, thiab qhov kev thov rau carbon fiber kuj poob qis. Tshwj xeeb tshaj yog thaum kev lag luam poob qis tshaj plaws hauv 2009, ntau lub tuam txhab carbon fiber ntau kuj tau ncua lossis qeeb lawv cov phiaj xwm kev loj hlob. Txawm li cas los xij, txij li xyoo 2010, nrog kev txhim kho ntawm kev lag luam ntsoog, kev lag luam thoob ntiaj teb carbon fiber tau pom cov cim ntawm kev rov qab los sai. Qhov kev thov loj loj txhawb kev rov qab los ntawm kev lag luam carbon fiber ntau, yog li qhov kev thov tag nrho ntawm cov roj carbon fiber tseem tseem nce ntxiv. Tam sim no, lub ntiaj teb carbon fiber ntau lawm tau mus txog ntau tshaj 40,000 t / xyoo. Nrog rau kev nthuav dav ntawm kev siv carbon fiber ntau, kev lag luam xav tau carbon fiber ntau ntxiv. Cov pa roj carbon fiber ntau thiab nws cov khoom sib xyaw Cov khoom siv kev lag luam tau qhia txog kev txhim kho zoo. Raws li cov koom haum cuam tshuam] kev kwv yees, lub ntiaj teb cov pa roj carbon fiber ntau yuav loj hlob sai ntawm tus nqi ntawm 13% hauv ib xyoos, thiab lub ntiaj teb xav tau carbon fiber ntau yuav ncav cuag 100,000 tons hauv 2018. Lub ntiaj teb cov tuam txhab carbon fiber ntau yog Nyiv Toray, Toho. Rayon thiab Mitsubishi Rayon, Tebchaws Asmeskas HEXCEL, ZOLTEK, thiab ALDILA, nrog rau ob peb lub tuam txhab xws li SGL SGL Group hauv Tebchaws Yelemees thiab Taekwang Industries hauv Kaus Lim Qab Teb.

Kev kwv yees ntawm carbon fiber kev lag luam rau 2030:
Txij li thaum xyoo 2010, qhov kev faib ua feem ntawm cov pa roj carbon fiber ntau hauv kuv lub teb chaws qhov xav tau carbon fiber ntau tau nce los ntawm 4.8% mus rau 37.8%. Piv nrog rau 31.7% hauv 2019, qhov kev loj hlob ntawm 2020 yog 53.8%. Kev loj hlob sai ntawm ntau dua 30% rau peb xyoos sib law liag.
Nyob rau hauv 2019, tag nrho lub ntiaj teb no carbon fiber xav tau yog hais txog 103,700 tons, nce li ntawm 12% xyoo-rau-xyoo piv rau 2018. Ntawm lawv, cov carbon fiber xav tau rau cua zog hniav, aerospace, thiab kev ua si thiab leisure yog 25,500 tons. , 23,500 tons, thiab 15,000 tons, feem. 24.59%, 22.66%, 14.46% ntawm tag nrho. Xyoo 2030, qhov kev thov rau carbon fiber ntau yuav tsum ncav cuag 422,200 tons.
Xyoo 2021, vim cua fais fab thiab txoj cai hloov kho nyob rau hauv Tuam Tshoj txoj kev lag luam carbon fiber, cov khoom ntawm carbon fiber precursors yog nruj, thiab tus nqi ntawm raw cov ntaub ntawv tau nce sharply. 2022 tau los txog.
Yav Tom Ntej Composites Co., Ltd. yuav txuas ntxiv tuav nws lub hom phiaj qub thiab nquag tsim cov thev naus laus zis tshiab thiab cov khoom tshiab Cov neeg siv khoom muab cov khoom lag luam zoo tshaj plaws thiab kev pabcuam.
