Carbon fiber braiding tshuabyog ib tug kuj high-endbraiding tshuabkhoom ntawm no series ntawm braiding tshuab.Piv nrog rau cov khoom siv braiding ib txwm muaj xws li paj rwb xov thiab hlau xaim, carbon fiber braiding tshuab muaj cov txheej txheem ntau dua thiab cov qauv tsim thiab tsim nyuaj.
Txawm li cas los xij, nws yog qhov tsis lees paub tias piv rau cov khoom siv niaj hnub, cov pa roj carbon fiber ntau weaving muaj cov yam ntxwv zoo heev, thiab nws cov ntawv thov yav tom ntej yog qhov dav.Qhov no yog ib qho ntawm cov laj thawj vim li cas Benfa Technology yeej ib txwm ua cov pa roj carbon fiber ntau lub tshuab ua haujlwm tseem ceeb.
Piv nrog rau cov khoom siv niaj hnub, cov khoom siv carbon fiber ntau yog dab tsi?
1. Muaj zog tensile zog
Lub zog tensile ntawm carbon fiber yog li 2 txog 7 GPa, thiab tensile modulus yog li 200 txog 700 GPa.Qhov ceev yog li ntawm 1.5 mus rau 2.0 grams ib cubic centimeter, uas yog txiav txim siab los ntawm qhov kub thiab txias ntawm cov txheej txheem carbonization ntxiv rau cov qauv ntawm cov thawj lo lo ntxhuav.Feem ntau tom qab qhov kub thiab txias 3000 ℃ graphitization kho, qhov ceev tuaj yeem ncav cuag 2.0 grams ib cubic centimeter.Tsis tas li ntawd, nws qhov hnyav yog qhov hnyav heev, nws lub zog tshwj xeeb yog sib dua li txhuas, tsawg dua 1/4 ntawm cov hlau, thiab nws lub zog tshwj xeeb yog 20 npaug ntawm cov hlau.Lub thermal expansion coefficient ntawm carbon fiber txawv ntawm lwm cov fibers, thiab nws muaj cov yam ntxwv ntawm anisotropy.
2. Me thermal expansion coefficient
Cov thermal expansion coefficient ntawm feem ntau carbon fiber nws tus kheej yog qhov tsis zoo nyob hauv tsev (-0.5 ~ -1.6) × 10-6 / K, nws yog xoom ntawm 200-400 ℃, thiab 1.5 × 10-6 / K thaum nws tsawg dua 1000 ℃ .Cov khoom sib xyaw ua los ntawm nws muaj qhov ruaj khov expansion coefficient thiab tuaj yeem siv los ua tus qauv ntsuas ntsuas.
3. Zoo thermal conductivity
Feem ntau, cov thermal conductivity ntawm inorganic thiab organic cov ntaub ntawv tsis zoo, tab sis cov thermal conductivity ntawm carbon fiber yog ze rau cov hlau.Ua kom zoo dua ntawm qhov kom zoo dua no, nws tuaj yeem siv los ua cov khoom siv rau cov khoom siv hluav taws xob hnub ci thiab cov khoom siv hluav taws xob ua hluav taws xob nrog cov khoom siv hluav taws xob zoo sib xws.
4. Mos thiab processability
Ntxiv nrog rau cov yam ntxwv ntawm cov ntaub ntawv carbon dav dav, carbon fiber woven fabrics muaj anisotropic softness nyob rau hauv tsos thiab tuaj yeem ua tiav rau hauv ntau yam ntaub.Vim lawv qhov tshwj xeeb lub ntiajteb txawj nqus me me, lawv muaj lub zog siab ntawm cov axis fiber ntau.Carbon fiber reinforced rings Oxygen resin composite cov ntaub ntawv muaj qhov ntsuas siab tshaj plaws ntawm lub zog tshwj xeeb thiab cov qauv tshwj xeeb ntawm cov khoom siv uas twb muaj lawm.
5. Tsawg kub tsis kam
Cov pa roj carbon fiber muaj qhov kub thiab txias tsis kam, xws li tsis nkig nyob rau hauv cov kua nitrogen kub.
6. Corrosion kuj
Cov pa roj carbon fiber ntau muaj kev tiv thaiv zoo rau cov organic solvents, acids, thiab alkalis.Nws tsis yaj los yog o.Nws muaj qhov zoo tshaj plaws corrosion kuj thiab tsis muaj teeb meem ntawm xeb.
7. Zoo hnav tsis kam
Cov pa roj carbon fiber ntau thiab hlau tsis tshua hnav thaum rub tawm ib leeg.Cov pa roj carbon fiber ntau yog siv los hloov cov asbestos los ua cov ntaub ntawv sib txhuam qib siab, uas tau siv los ua cov ntaub ntawv nres tsheb rau cov dav hlau thiab tsheb.
8. Zoo kub tsis kam
Kev ua haujlwm ntawm carbon fiber ntau ruaj khov hauv qab 400 ° C, thiab tsis muaj kev hloov pauv ntau txawm tias nyob ntawm 1000 ° C.Qhov kub tsis kam ntawm cov ntaub ntawv sib xyaw feem ntau yog nyob ntawm qhov kub tsis kam ntawm matrix.Lub sij hawm ntev tshav kub tsis kam ntawm resin-raws li cov ntaub ntawv sib xyaw tsuas yog kwv yees li 300 ℃, thiab qhov kub tsis kam ntawm ceramic-based, carbon-based thiab hlau-raws li cov ntaub ntawv sib xyaw tuaj yeem phim cov carbon fiber nws tus kheej.Cov ntaub ntawv carbon fiber ntau yog siv dav hauv kev lag luam aerospace raws li cov ntaub ntawv kub resistant.
9. Zoo heev fineness
Cov pa roj carbon fiber ntau muaj qhov zoo tshaj plaws (ib qho piv txwv ntawm kev ua kom zoo yog tus naj npawb ntawm grams ntawm 9000-meter-ntev fiber ntau), feem ntau tsuas yog li 19 grams, thiab lub zog tensile txog li 300 kg ib micron.Ob peb lwm cov ntaub ntawv muaj ntau yam zoo li carbon fiber.
10. Kev cuam tshuam tsis zoo thiab yooj yim rau kev puas tsuaj
Oxidation tshwm sim nyob rau hauv qhov kev txiav txim ntawm cov kua qaub muaj zog, lub zog electromotive ntawm carbon fiber yog qhov zoo, thiab lub zog electromotive ntawm aluminium alloy yog qhov tsis zoo.Thaum cov ntaub ntawv carbon fiber ntau yog siv ua ke nrog txhuas alloys, hlau carbonization, carburization thiab electrochemical corrosion yuav tshwm sim.Yog li ntawd, carbon fiber yuav tsum tau kho deg ua ntej siv.
