Tsav los ntawm cov thev naus laus zis tshiab, kuj tseem muaj cov kev xav tau siab rau kev ua haujlwm ntawm cov khoom siv.Lub sijhawm no, cov khoom siv ua haujlwm siab yuav raug siv los hloov cov khoom siv hlau niaj hnub no.Tau kawg, qee cov neeg uas tsis paub cov khoom siv no zoo heev yuav siv carbon fiber.Cov khoom siv yog piv nrog cov iav fiber ntau thiab aluminium alloy cov ntaub ntawv, yog li tsab xov xwm no yuav tham txog kev sib piv ntawm peb cov ntaub ntawv no.
Cov khoom siv carbon fiber ntau vs iav fiber ntau
Los ntawm qhov kev xav ntawm cov khoom, nws tuaj yeem pom tias carbon fiber yog cov khoom siv fiber ntau uas muaj 90% cov hnub qub.Tam sim no nws yog feem ntau siv los rho tawm carbon fiber los ntawm polyacrylonitrile, los yog los ntawm viscose fiber los yog pitch fiber, uas yog oxidized thiab carbonized ntawm kub.ntau lawm.Nws tau hais tias qhov ntom ntawm cov khoom siv fiber ntau tsuas yog 1.5g / cm3, yog li qhov zoo ntawm cov khoom siv fiber ntau yuav yog lub teeb heev.Tom qab ntawd cov khoom siv carbon fiber tuaj yeem sib xyaw nrog hlau, ceramic, resin thiab lwm yam matrices los ua cov ntaub ntawv carbon fiber ntau.Cov iav fiber ntau lub khob hliav qab yog cov khoom siv tsis zoo nrog kev ua haujlwm zoo.Muaj ntau yam ntaub ntawv uas tsis yog xim hlau, uas yog ua los ntawm xya hom ores, xws li E pob zeb, quartz xuab zeb, limestone, dolomite, boronite, thiab boronite, los ntawm high-temperature melting, hlau kos duab, winding, thiab weaving.
Los ntawm qhov kev xav ntawm kev ua tau zoo, cov ntaub ntawv carbon fiber muaj qhov tshwj xeeb me me, thiab cov kev qhia dav dav ntawm lub zog tshwj xeeb thiab cov qauv tshwj xeeb yog qhov zoo tshaj rau cov khoom siv uas twb muaj lawm.Lawv tuaj yeem tiv taus qhov kub thiab txias hauv qhov chaw uas tsis yog oxidizing, thiab muaj zog zoo zog.Qhov tshwj xeeb kub thiab hluav taws xob conductivity yog nruab nrab ntawm cov hlau tsis muaj hlau thiab hlau.Nws muaj qhov zoo X-ray permeability thiab tuaj yeem siv rau hauv kev kho mob.Nws muaj kev tiv thaiv corrosion zoo, yog insoluble thiab tsis o nyob rau hauv cov organic solvents, acids, thiab cov kuab tshuaj, thiab muaj zoo heev corrosion kuj.Cov iav fiber ntau yog ib qho inorganic fiber, tsis-flammable, zoo rwb thaiv tsev, zoo tshuaj tiv thaiv, siab modulus elasticity, zoo rigidity, tsis tshua muaj dej nqus, txawm tias tus nqi qis dua carbon fiber, tab sis tag nrho cov kev ua tau zoo tsis zoo li carbon fiber. .
Kev sib piv ntawm cov khoom siv carbon fiber thiab aluminium alloy khoom
Qhov zoo ntawm carbon fiber composites yog sib dua.Qhov ceev ntawm carbon fiber composites yog 1.7g / cm3, thaum lub ntom ntawm aluminium alloy yog hais txog 2.7g / cm3, uas ua rau cov nyhuv txo qhov hnyav ntawm carbon fiber composites zoo dua.
Lub zog compressive ntawm cov khoom siv fiber ntau nyob rau hauv ntu hla mus txog 20G, thaum lub zog ntawm peb cov aluminium alloy tsuas tuaj yeem ncav cuag 70g, uas txhais tau hais tias cov pa roj carbon fiber ntau dhau ntawm aluminium alloy ntawm lub zog, thiab nws lub zog yog. ntau dua li ntawm aluminium alloy.Qhov no yog vim li cas carbon fiber composites sawv tawm ntawm ntau yam khoom siv.Qhov khoov tsis kam ntawm carbon fiber ntau dua li cov ntaub ntawv hlau.
Thaum lub sij hawm vuam txheej txheem ntawm aluminium alloy, nws yog ib qho yooj yim los tsim cov ntaub ntawv yas, thiab carbon fiber composite cov ntaub ntawv muaj kev ua tau zoo dua nyob rau hauv kev ua, vim carbon fibers muaj ob qho tib si softness thiab processability ntawm textile fibers ua ntej tsim, yog li cov txheej txheem tsim ntawm lawv. tsim kev ua tau zoo yog qhov zoo dua, thiab kev ua haujlwm corrosion kuj nyob rau hauv qee qhov chaw tshwj xeeb kuj zoo dua.
Nyob rau hauv txoj kev no, nws tuaj yeem pom tias nws tsis yog qhov tsim nyog rau cov ntaub ntawv carbon fiber ntau los ua cov kub kub hauv cov khoom lag luam, tab sis nws tsis tau txhais hais tias carbon fibers tau siv txhua qhov chaw, thiab ntau dua nyob ntawm qhov xav tau.Piv txwv li, iav fiber ntau yog qhov zoo dua rau hluav taws xob rwb thaiv tsev.Yog tias koj xav tau cov khoom siv carbon fiber ntau, txais tos hu rau tus editor ntawm Cov Khoom Tshiab.
Xinmai yog cov chaw tsim khoom tshwj xeeb hauv kev tsim cov khoom siv carbon fiber ntau.Nws muaj kaum xyoo ntawm kev nplua nuj nyob hauv kev ua haujlwm ntawm carbon fiber.Nws koom nrog hauv kev tsim thiab ua cov khoom siv carbon fiber ntau.Nws muaj cov cuab yeej molding tiav thiab zoo meej ntxiv cov cav tov, thiab tuaj yeem ua tiav ntau yam khoom siv carbon fiber ntau.Kev tsim khoom yog customized raws li cov duab kos.Cov pa roj carbon fiber ntau cov khoom tsim tawm kuj tau xa tawm mus rau ntau qhov kev lag luam, thiab tau txais kev lees paub thiab qhuas.
