- Lub peev xwm zoo kawg nkaus ntawm Carbon Fiber Reinforced Polymers.
Cov pa roj carbon fiberReinforced Polymer Composites (CFRP) yog lub teeb yuag, cov ntaub ntawv muaj zog siv hauv kev tsim khoom ntawm ntau yam khoom siv hauv peb lub neej txhua hnub. Nws yog ib lo lus siv los piav txog fiber ntaucov khoom sib xyawuas siv cov pa roj carbon fiber ua lub hauv paus kev tivthaiv. Nws yuav tsum raug sau tseg tias "P" hauv CFRP tuaj yeem sawv ntsug rau "yas" tsis yog "polymer."
Feem ntau, CFRP composites siv cov thermosetting resins xws li epoxy,polyester, los yog vinyl ester. Txawm tiasthermoplastic resinsyog siv nyob rau hauv CFRP Composites, "Carbon Fiber Reinforced Thermoplastic Composites" feem ntau mus los ntawm lawv tus kheej acronym, CFRTP composites.
Thaum ua hauj lwm nrog composites los yog nyob rau hauv lub composites kev lag luam, nws yog ib qho tseem ceeb kom to taub cov ntsiab lus thiab acronyms. Qhov tseem ceeb tshaj, nws yog ib qho tsim nyog kom nkag siab txog qhovCov khoom ntawm FRP compositesthiab muaj peev xwm ntawm ntau yam kev txhawb zog xws li carbon fiber.
Cov khoom ntawm CFRP Composites
Cov ntaub ntawv sib xyaw, ntxiv nrog cov pa roj carbon fiber ntau, txawv dua li lwm cov FRP composites siv cov khoom siv xws li fiberglass lossisaramid fiber ntau. Cov khoom ntawm CFRP composites uas muaj txiaj ntsig zoo suav nrog:
Lub Teeb Nyhav:Ib txwmfiberglass reinforced compositesiv cov iav fiber ntau txuas ntxiv nrog cov fiber ntau ntawm 70% iav (qhov hnyav ntawm iav / tag nrho qhov hnyav), feem ntau yuav muaj qhov ceev ntawm .065 phaus ib lub cubic inch.
Lub caij no, CFRP composite, nrog tib 70% fiber ntau qhov hnyav, feem ntau yuav muaj qhov ceev ntawm .055 phaus ib cubic nti.
Ua kom muaj zog:Tsis tsuas yog carbon fiber composites sib zog, tab sis CFRP composites muaj zog ntau thiab stiffer rau ib chav tsev ntawm qhov hnyav. Qhov no muaj tseeb thaum muab cov pa roj carbon fiber ntau sib xyaw rau iav fiber ntau, tab sis ntau dua li thaum piv rau cov hlau.
Piv txwv li, txoj cai tsim nyog ntawm tus ntiv tes xoo thaum piv cov hlau rau CFRP cov khoom sib xyaw yog tias cov qauv carbon fiber ntau sib npaug zog feem ntau yuav hnyav 1/5 ntawm cov hlau. Koj tuaj yeem xav txog yog vim li cas cov tuam txhab tsheb tau tshawb xyuas siv carbon fiber ntau ntawm cov hlau.
Thaum muab piv CFRP composites rau txhuas, ib qho ntawm cov hlau siv lightest, cov qauv kev xav yog tias cov qauv txhuas ntawm qhov sib npaug ntawm lub zog yuav hnyav li 1.5 npaug ntawm cov qauv carbon fiber.
Tau kawg, muaj ntau qhov sib txawv uas tuaj yeem hloov qhov kev sib piv no. Cov qib thiab zoo ntawm cov ntaub ntawv yuav txawv, thiab nrog composites, lubkev tsim khoom, fiber ntau architecture, thiab qhov zoo yuav tsum tau coj mus rau hauv tus account.
Disadvantages ntawm CFRP Composites
Tus nqi:Txawm hais tias cov khoom siv zoo heev, muaj qhov laj thawj vim li cas carbon fiber tsis siv hauv txhua daim ntawv thov. Tam sim no, CFRP cov khoom sib xyaw yog cov nqi txwv tsis pub siv ntau zaus. Raws li qhov kev lag luam tam sim no (muab khoom thiab xav tau), hom carbon fiber (aerospace vs. coj mus muag qib), thiab fiber ntau cab loj, tus nqi ntawm carbon fiber yuav txawv heev.
Cov roj carbon fiber ntau ntawm tus nqi-ib-phaus tuaj yeem nyob qhov twg ntawm 5-lub sijhawm rau 25-lub sijhawm kim dua fiberglass. Qhov kev sib txawv no ntau dua thaum piv cov hlau rau CFRP cov khoom sib xyaw.
conductivity:Qhov no tuaj yeem yog ob qho txiaj ntsig zoo rau carbon fiber ntau, lossis qhov tsis zoo nyob ntawm daim ntawv thov. Cov pa roj carbon fiber ntau yog conductive, thaum iav fiber ntau yog insulative. Ntaudaim ntawv thov siv iav fiber ntau, thiab tsis tuaj yeem siv carbon fiber lossis hlau, nruj me ntsis vim yog cov conductivity.
Piv txwv li, hauv kev lag luam hluav taws xob, ntau yam khoom yuav tsum tau siv cov iav fibers. Nws kuj yog ib qho ntawm cov laj thawj vim li cas cov ntaiv siv iav fiber ntau raws li cov ntaiv. Yog hais tias ib tug fiberglass ntaiv tau los nyob rau hauv kev sib cuag nrog ib tug fais fab kab, txoj kev pheej hmoo ntawm electrocution yog tsawg dua. Qhov no yuav tsis yog qhov teeb meem nrog CFRP ntaiv.
Txawm hais tias tus nqi ntawm CFRP composites tseem tseem siab, kev hloov kho tshiab hauv kev tsim khoom txuas ntxiv tso cai rau cov khoom lag luam raug nqi ntau dua. Cia siab tias, hauv peb lub neej, peb yuav tuaj yeem pom cov txiaj ntsig zoo ntawm cov pa roj carbon fiber ntau siv nyob rau hauv ntau yam ntawm cov neeg siv khoom, kev lag luam, thiab kev siv tsheb.
