1. Cov pa roj carbon fiber ntau yog feem ntau muaj ntawm polyacrylonitrile-}} kev ua tau zoo matrices, nrog cov txiaj ntsig tseem ceeb
Carbon Fiber yog ib qho khoom siv carbon monoxide High-polymer nrog cov ntsiab lus carbon ntau dua 90%
Carbon fiber muaj cov kws kho tshuab zoo nkauj, thiab nws cov kev nqus tshwj xeeb yog tsawg dua 1/4 ntawm cov hlau. Lub zog tensile ntawm cov pa roj carbon fiber ntau feem ntau yog ntau dua 3500Mpa, uas yog 7 {}}}}}}}} 9 zaug ntawm cov hlau. Nws yog cov fiber ntau nrog lub zog siab tshaj plaws thiab cov hluav taws xob muaj zog, kev ua kom muaj zog tsis kam, cov cua sov} {8}- tshav kub nkag, tsis sib nqus Tab sis nws muaj cov yam ntxwv ntawm electromagnetic tiv thaiv cov nyhom, thiab yog ib qho khoom siv tswv yim tseem ceeb rau kev txhim kho kev tiv thaiv lub teb chaws thiab kev lag luam tub rog thiab kev lag luam hauv tebchaws. Nws yog dav siv nyob rau hauv kev ua tub rog, aerospace, kev lag luam khoom, khoom siv hluav taws xob, kev thauj khoom siv, kev thauj khoom, kev tsim kho thiab nws cov kev teeb tsa kev teeb tsa.
Cov pa roj carbon fiber tuaj yeem ua haujlwm raws li qhov sib txawv xws li hom prefursor, txoj kev tsim khoom, thiab kev ua haujlwm. Raws li hom ntawm precursor, carbon fiber tuaj yeem faib rau hauv polyacrylonitrile (evk)-} {}} raws carbon fiber. Ntawm lawv, polyacrylonitrile {{5} Raws cov fiber ntau muaj qhov zoo ntawm cov khoom tiav zoo, txheej txheem yooj yim, thiab cov khoom lag luam yooj yim, thiab cov khoom lag luam yooj yim, thiab cov khoom siv zoo heev. Txij li thaum nws addutes nyob rau xyoo 1960, nws tau ua tiav sai sai ntawm txoj haujlwm, suav rau ntau dua 90% ntawm tag nrho cov carbon fiber. Tam sim no, carbon fiber ntau thiab feem ntau yog hais txog pan - raws cov fiber roj fiber.
Raws li tus naj npawb ntawm cov fibers, carbon fiber tuaj yeem faib ua cov fiber ntau, thiab ua kom muaj zog}} {- lub zog siab qauv. Rad ME carbon fiber yog pib 1k, 3k, thiab 6k, thiab maj mam tsim mus rau 12k thiab 24k. It is mainly used in high-tech fields such as national defense and military industry, as well as sports and leisure products, such as aircraft, missiles, rockets, satellites, fishing gear, golf clubs, tennis rackets, etc. Large tow carbon fiber usually refers to carbon fiber above 48K, including 48K, 60K, 80K, etc., which are mainly used in industrial fields, including textiles, medicine and health, Electromechanical, neeg txua nkoj, tsheb thauj mus los thiab lwm yam, thiab lwm yam.
Carbon fiber ntau cov ntaub ntawv yog muaj los ntawm cov ntawv Matrix thiab cov khoom siv roj carbon fiber ntau ntxiv. Los ntawm kev sib nrig sib txawv ntawm Matrix cov ntaub ntawv thiab cov pa roj carbon fiber hauv kev ua tau zoo, cov nyhuv symistic yog tsim tawm. Cov khoom ua tau zoo ntawm cov pa roj carbon fiber ntau cov ntaub ntawv yog qhov zoo dua li ntawm cov ntaub ntawv qub thiab ua kom tau ntau yam. Cov khoom siv roj teeb muaj cov yam ntxwv muaj cov yam ntxwv ntawm lub teeb yuag, cov khoom siv zoo li cov khoom siv, cov khoom siv hloov tau yooj yim, cov khoom siv tau, thiab tus nqi qis. Lawv ua lub luag haujlwm tseem ceeb hauv kev txhim kho lub teb chaws kev tiv thaiv thiab tub rog, thiab tau siv dav hauv ntau lub dav hlau, drones, cuaj cuaj, tua tawm, thiab satellites.
Nyob rau hauv carbon fiber ntau cov ntaub ntawv, cov khoom matrix feem ntau yog redin - raws li, suav rau ntau dua 90% ntawm kev lag luam sib koom. Cov khoom matrix tau muab faib ua ob pawg: hlau thiab tsis - hlau. Cov khoom siv hlau sib xyaw ua ke yog txhuas, tooj liab, thiab cov roj hmab, suav nrog ntau dua 90% ntawm tag nrho cov roj carbon fiber ntau dua kev ua lag luam.
2. Tom qab ob lub vuag ntawm kev loj hlob, daim ntawv thov teb txuas ntxiv mus nthuav dav
Kev txhim kho ntawm carbon fiber nyob rau hauv xyoo 1950 thiab 1960. Tebchaws Asmeskas, Nyiv, thiab Tebchaws Askiv yog thawj tus tsim cov txheej txheem roj carbon monatory. Xyoo 1958, Roger nqaij npuas of Union Carbide Corporation hauv Tebchaws Asmeskas ua kom sov rayon hauv Argon thiab ua kom dhau los ua fiber roj fiber. Txij thaum ntawd los, lub peev xwm ntawm cov khoom siv fiber ntau cov roj carbon tau pom zoo. Xyoo 1960, Richard Millington ntawm Hithompson fiberglass tuam txhab (USA) tsim ib txoj kev los nce cov ntsiab lus carbon fibers rau 99WT%. Nyob rau xyoo 1960, Nyij Pooj thiab British tuam txhab tau coj lub sim tshuab thev naus laus zis ntawm polyacrylonitrile (lauj kaub)} Raws li cov muaj fiber ntau lawm. Xyoo 1959, Akio Shindo ntawm Oska Institho Cov Ntaub Ntawv Tshuab thev naus laus zis nrog cov ntsiab lus carbon muaj txog 55wt% siv txoj kev muaj nqi; Toray Industries ntawm Nyiv Kev sim -}} tsim tawm cov fict, Ln Philas tsim cov khoom siv rau cov pa roj carbon monoxide rau cov pa roj carbon monoxide rau lub tebchaws xyoo 1970. Tom qab, kev tshawb nrhiav hauv tebchaws thiab kev loj hlob ntawm cov ntawv tso cai rau cov txheej txheem rubsroyce, Morganite thiab Tsev Hais Plaub.
Cov pa roj carbon fiber ntau cov khoom siv kev lag luam pib hauv xyoo 1970 thiab 1980s. Hauv kev txhim kho cov pa roj carbon fiber ntau dua cov cuab yeej siv tshuaj, Tebchaws Asmeskas, Tebchaws Askiv thiab Nyiv tau ua haujlwm sib raug zoo ua ke. Xyoo 1970, Toray kos npe rau kev sib koom tes carbide corology ntawm Tebchaws Meskas, thiab Lub Chaw Haujlwm Carbide Corporation ntawm Tebchaws Meskas cov khoom lag luam Carbide cov khoom lag luam muaj cov khoom lag luam carbon fiber ntau. Xyoo 1971, Toray tau tsim 12 {{{} Cov roj carbon fiber ntau thiab pib tsim cov roj carbon fiber ntau thiab pib tsim cov dav hlau roj carbon monoxide, thiab pib tsim cov dav hlau roj carbon monoxide Tom qab, cov dav hlau tuam ntxhab xws li boeing thiab airbus pib tshawb cov ntawv thov ntawm cov roj carbon fiber ntau. Xyoo 1982, Boeing 757, Boeing 767 thiab Chaw Shuttle pib siv T300 Carbon Fiber. CFRP tau nkag mus rau qhov kev thov engineering ntawm aerospace qauv, suav nrog tub rog thiab pej xeem aircraft. Nyob rau xyoo 1980, nrog ib qho- kab kev lag luam ntau lawm ntawm cov khoom lag luam khoom siv tau ntau dua ntawm 100, lub sij hawm Mid-early and and, thiab T1000, thiab tom qab m60J. Nrog rau kev siv hluav taws xob thoob plaws hauv cov roj carbon fiber ntau hauv cov dav hlau, Toray's ntau lawm ntau tshaj 10,000 tons los ntawm 1988.
Carbon fiber composites tau muaj txog ob nthwv dej ntawm kev xav tau, thawj tsav los ntawm aerospace teb. Thawj nthwv dej ntawm daim ntawv thov ntawm cov roj carbon fiber ntau tshwm sim hauv cov khoom siv roj carbon monoxide txo qis, muaj cov nqi tsim kho roj teeb, thiab cov nqi sib txawv, thiab txo tus nqi ntawm kev koom ua ke. Hauv 1990, Toray's CFRP Cov Npaj Txhim Kho Xyoo 2005, Airbus tau pib A350 XWBIT txoj haujlwm, uas tseem siv ntau npaum li cas ntawm CFR (53WT%).
The second wave of demand for carbon fiber composites was driven by non-aerospace industries. Since the 2010s, the application of carbon fiber composites has expanded dramatically from aerospace to non-aerospace industrial uses, and is characterized by large quantities and low costs. In 2007, Zoltek cooperated with wind turbine OEM Vestas to use carbon fiber in wind turbine blades. Compared with blades made of glass fiber composites, the use of carbon fiber composites in 60-meter-long blades is expected to reduce weight by 38%, reduce costs by 14%, and extend blade life. In 2014, Toray acquired Zoltek, a world-leading supplier of large-tow (>50k) carbon fiber, thiab nws cov pa roj carbon fiber ntau yuav nce ntxiv rau 35,000 tons / xyoo.
