1. Feem ntau ntawm cov khoom siv raw carbon los ntawm Asia
Roob tsheb kauj vab carbon fiber ntauyog tsim los ntawm polyacrylonitrile (PAN) fibers. Polyacrylonitrile fibers yog rhuab mus rau qhov kub thiab txias, thiab tag nrho cov khoom uas tsis yog-carbon nyob rau hauv fibers raug hlawv, tawm tsuas yog ib tug series ntawm nyias nyias, ntev fibers. Qhov ntau txaus rau kev ua, cov khoom yuav nruj dua.
Qhov no yog txheej txheem kev lag luam nyuaj, thiab tsuas yog ob peb lub tuam txhab hauv ntiaj teb muaj peev xwm tsim cov khoom siv roj carbon fiber ntau. Los ntawm 2010 US Department of Energy daim ntawv qhia, peb tuaj yeem pom tias ntau dua 90% ntawm lub ntiaj teb cov pa roj carbon fiber ntau los ntawm tsuas yog rau lub tuam txhab: Toray, Teijin Group, Mitsubishi Rayon, Trotec America, Hexcel thiab Cytec America. Toray, Teijin thiab Mitsubishi yog lub luag haujlwm rau yuav luag ob feem peb ntawm lub ntiaj teb carbon fiber ntau lawm. Zoltec, Hexcel thiab Cytec yog lub hauv paus hauv Tebchaws Meskas thiab tsim muaj tsawg dua li ib feem peb ntawm lub ntiaj teb cov khoom siv carbon fiber ntau.
2. Muaj ntau tshaj ib hom carbon fiber siv hauv tsheb kauj vab
Cov pa roj carbon fibers muaj nyob rau hauv ntau qhov kev nthuav qhia: cov khoom siv raw, cov ntaub fiber ntau, thiab cov fibers luv luv. Short-cut fibers feem ntau yog siv nyob rau hauv pedals. Cov pa roj carbon fiber ntau yog siv rau hauv cov thav ntawv. Cov pa roj carbon fiber ntau yog raws nraim li nws lub npe suab zoo li: ib daim ntaub txuas ntxiv carbon fiber uas zoo nkaus li zoo li daim ntawv yob ntawm cov ntaub uas tau txais qhov txhab ntawm lub qhov loj heev. Raw filaments tsis tshua muaj nyob rau hauv kev lag luam tsheb kauj vab, thiab tsuas yog ob peb lub tuam txhab tsheb kauj vab muaj peev xwm ua tau li ntawd.
3. Ntxiv rau carbon fiber, lub thav duab xav tau ...
Qhov peb feem ntau hu ua "carbon fiber" yog cov khoom siv carbon fiber ntau, thiab cov khoom siv fiber ntau tsis yog cov khoom siv hauv koj lub tsheb kauj vab nkaus xwb. Tias yog vim li cas cov pa roj carbon fiber ntau nruj nruj yog qhov xwm txheej: thaum nws tsuas yog cov pa roj carbon fiber ntau los ntawm nws tus kheej, nws tsis yooj yim heev thiab muaj kev sib cais thiab tawg. Txhawm rau khaws nws cov khoom, carbon fiber yog dipped hauv epoxy resin (ib yam khoom zoo li gel) ua ntej nkag mus rau hauv pwm, tsim cov khoom sib xyaw. Feem ntau cov pa roj carbon fiber ntau siv hauv kev lag luam tsheb kauj vab yog ua tiav hauv daim ntawv no hauv cov txheej txheem hu ua "prepreg".
Cov resin ua ob txoj haujlwm. Thawj txoj haujlwm yog ua kom cov pa roj carbon fibers ua ke. Qhov thib ob txoj haujlwm yog tias cov resin ntxiv toughness thiab durability. Cov yas me me yuav deform raws li qhov cuam tshuam (xws li, cuam tshuam los yog khib nyiab), yog li pab kom nqus tau cov pounding yam tsis ua rau mob hnyav ntawm cov fibers.
4. Cov pa roj carbon fiber ntau siv hauv cov ncej yog sib xyaw
Ib qho zoo carbon fiber thav duab yog tsim los ntawm kev sib xyaw ntawm carbon fibers, nrog rau ntau hom carbon fibers siv nyob rau hauv ntau txoj hauj lwm ntawm thav duab rau tej lub hom phiaj. High-modulus fibers yog kim (vim yog qhov nyuaj ntawm cov txheej txheem), yog li cov tuam txhab tsheb kauj vab yog cov ntse txaus los siv cov khoom me me ntawm cov khoom siv fiber ntau hauv cov chaw tseem ceeb xws li lub raj cua, lub hauv qab bracket, thiab rear diav rawg los tiv thaiv pedaling rog. thiab ua kom lub tsheb kauj vab muaj zog. Tab sis lub siab modulus fibers tau muab tso rau hauv pwm nrog cov qauv modulus, nruab nrab modulus thiab siab zog fibers los tsim cov kav ntev, kev ua tau zoo thiab kev caij tsheb zoo uas yuav tsum muaj carbon fiber ntau.
Tianjin Panda Technology Group Co., Ltd. yog ib pawg tuam txhab thev naus laus zis sib koom ua ke R & D, ntau lawm, muag thiab kev pabcuam. Cov pab pawg tau cog lus los muab cov kev daws teeb meem kev caij tsheb kauj vab ntse rau tib neeg thoob plaws ntiaj teb.
