Muaj pes tsawg qib sib txawv ntawm cov carbon fiber?
Ib nyuag keeb kwm ntawm carbon fiber
Cov roj carbon fiber nws lub hauv paus pib rau Thomas Edison Filament Kev sim thiab Roger Bacon thiab Roger Bacon thiab Roger daim av rau cov khoom siv niaj hnub.
Kev Lag Luam - nplai cov roj carbon fiber thawj zaug tshwm sim hauv 1960 nrogPolyacrylonitrile (Yias)Kev txhim kho ua ntej, hloov los ntawm kev txhim kho txuas ntxiv hauv kev ruaj khov thiab cov pa roj carbonancys kom tawm los ua kom tiav hnub no ntau hom kev ua haujlwm nyob rau niaj hnub no.
Xyoo 1970 pom ib tus neeg siv hluav taws xob nrawm nrawm, thiab los ntawm 1980s, fibers xws li Toray's TURAY's T300 thiab TMATE muaj lub zog thiab txhav.
Kev Tsim Kho Txheej Txheem Txheej txheem cej luam
Zeem ntawm pan -} Raws li cov pa roj carbon folbon: polymerization, fiber ntau, kev kho mob, thiab kom qhuav / siing.
PolymerizationTsim ib lub lauj kaub copolymer uas yog extruded rau hauv cov filaments txuas ntxiv uas siv cov kuab tshuaj zoo li DMSO lossis DMF.
ThaumThermal stabilization, cov fibers yog rhuab mus rau 200-300℃nyob rau hauv huab cua, crosslinking polymer chains kom thiaj li tsis pom zoo nyob rau hauv cov kauj ruam kub tom ntej.
Tuskev kub ntxhovQeb Kawm Ruaj Khov Fibers rau 1,000-3,000 Qib nyob rau hauv ib qho chaw inert, tsav tsheb tawm cov khoom siv tsis muaj roj teeb thiab tsim cov duab graphitic microstructure.
Tom qab carbonization, fibers yauv musNto Kho- Feem ntau oxidation lossis ntshav -}}} los qhia cov pab pawg ua haujlwm tau txhim kho.
Thaum kawg, asizingPolymer Txheej yog thov kom tiv thaiv fibers thaum lub sij hawm tuav thiab kom zoo sib xws nrog matrix resins.
Carbon Fiber ntau cov kev faib tawm
Lub ntsiab lus metric rau cov roj carbon fiber cov qib yogtensile modulus, ib qho kev ntsuas ntawm txhav txhav nyob rau hauv nro. Plaub tus thawj pawg muaj nyob:
Txheem Modulus (sm)
Tensile Modulus:~ 33 MSI (230 GPA)
Lub zog tensile:~ 2,500 MPa
Nqi:$ 7- $ 10 rau ib phaus (Industrial-qeb) SM Fibers, tseem hu uaSiab Zog, muab kev nyuaj heev thiab tawv tawv, ua rau lawv muaj dav siv dav hauvNtaus Pob Ncaws Pob, Kev Siv Tsheb Sib Tham, thiabCov Hom Phiaj General-Lub Hom PhiajComposites.
Nruab Nrab Modulus (IM)
Tensile Modulus:~ 42 MSI (290 GPA), nce txog 47 MSI (325 GPA) rau cov hom hwm hwm.
Lub zog tensile:~ 3,500 MPa
Tus nqi them nqi:~ 20-40% saum sm
Txhij fibers yog prized nyob rau hauvAerospace thawj cov qauv, High-xaus tsheb kauj vab thav ntawv, thiabPrecision Robotics, qhov twg rigidity ntxiv tau muab cov kev ua tau zoo nce.
High Modulus (Hm)
Tensile Modulus:~ 55 MSI (380 GPA)
Lub zog tensile:~ 4,000-4,500 MPa
Ua:Xav tau autoclave kho kom tsis txhob muaj brittleness
Hm fibers tshwm nyob rau hauvSatellite Cheebtsam, Lub rooj muag khoom kho qhov muag, thiabtub rog uav cua thav ntawvqhov twg maximizing stiffness yog qhov tseem ceeb.
Ultra-siab modulus (UHM)
Tensile Modulus:Txog li 130 MSI (900 GPA)
Lub zog tensile:~ 7,000 MPa
Thawj:Feem ntau cov av-tar-tar; yuav tsum muaj cov teeb meem tshwj xeeb
Uhm fibers xa cov siab tshaj plaws rauQhov Chaw Telescopes, Precision Science, thiabUa Ntej Kev Ncua Tawm Lub Tshuab, albeit ntawm 5-10 × cov nqi sm.
Kev Lag Luam VS Cov Chav Tshwj Xeeb
Dhau tensile modulus, cov fibers yog lag luam raws liKev Lag Luam (SM & IM)thiabTshwj xeeb (HM & UHM).
