Lub cev lub cev ntawm cov khoom sib xyaw yog dominated los ntawm fibers. Qhov no txhais tau hais tias thaum resins thiab fibers sib xyaw ua ke, lawv cov khoom zoo ib yam li cov fibers ntawm tus kheej. Cov ntaub ntawv ntsuam xyuas qhia tau hais tias cov khoom siv fiber ntau yog cov khoom siv uas nqa tau feem ntau ntawm cov khoom thauj. Yog li ntawd, kev xaiv ntaub yog qhov tseem ceeb thaum tsim cov qauv sib xyaw.
Pib tus txheej txheem los ntawm kev txiav txim siab hom kev txhawb zog uas xav tau rau koj qhov project. Cov chaw tsim khoom lag luam tuaj yeem xaiv los ntawm peb hom kev txhawb nqa: iav fiber ntau, carbon fiber thiab Kevlar® (aramid fiber). Cov iav fiber ntau zoo li yog qhov kev xaiv thoob ntiaj teb, thaum cov roj carbon fiber muaj qhov tawv tawv thiab Kevlar® siab tiv thaiv. Nco ntsoov tias hom ntaub tuaj yeem sib xyaw ua ke hauv laminates los tsim cov khoom sib xyaw uas muab cov txiaj ntsig ntawm ntau tshaj ib qho khoom.
Fiberglass Reinforcements
Fiberglass yog cov khoom siv paub. Fiberglass yog lub hauv paus ntawm kev lag luam composites. Nws tau siv ntau daim ntawv thov sib xyaw txij li xyoo 1950 thiab nws cov khoom siv lub cev tau nkag siab zoo. Fiberglass yog lub teeb yuag, muaj lub zog tensile thiab compressive zog, tuaj yeem tiv taus kev puas tsuaj thiab kev thauj khoom cyclic, thiab yooj yim los daws. Cov khoom uas tshwm sim los ntawm kev tsim khoom yog hu ua fiberglass reinforced yas (FRP) khoom. Nws tshwm sim hauv txhua qhov chaw ntawm lub neej. Yog vim li cas vim li cas nws thiaj li hu ua fiberglass yog vim hais tias hom fiber ntau filament no yog tsim los ntawm melting quartz thiab lwm yam ore ntaub ntawv nyob rau hauv kub kub rau hauv ib lub khob slurry. Thiab ces rub tawm ntawm kev kub ceev filaments. Hom fiber ntau no yog vim muaj qhov sib txawv muaj ntau yam hauv. Qhov zoo yog qhov kub tsis kam, corrosion kuj, muaj zog ntau dua. Kev rwb thaiv tsev zoo. Thiab carbon fiber muaj tib qhov tsis zoo yog cov khoom yog nkig ntau dua. Tsis zoo ductility. Tsis hnav-resistant. Tam sim no, kev rwb thaiv tsev, kev txuag hluav taws xob, kev tiv thaiv corrosion yooj yim thiab ntau lwm qhov chaw muaj kev siv cov iav fiber reinforced yas.
Fiberglass yog siv dav tshaj plaws ntawm tag nrho cov khoom muaj. Qhov no feem ntau yog vim nws tus nqi qis thiab nruab nrab lub cev muaj zog. Fiberglass zoo haum rau cov haujlwm niaj hnub thiab qhov chaw uas tsis tas yuav xav tau cov ntaub fiber ntau ntxiv rau lub zog thiab kav ntev.
Txhawm rau ua kom muaj zog ntawm fiberglass, nws tuaj yeem siv nrog epoxy resins thiab tuaj yeem kho tau siv cov txheej txheem lamination. Nws yog qhov zoo rau cov ntawv thov hauv tsheb, marine, kev tsim kho, tshuaj lom neeg thiab aerospace kev lag luam thiab feem ntau siv hauv cov khoom ua si.
Aramid Fiber Reinforcement
Aramid fiber ntau yog cov khoom siv tshuaj lom neeg siab. Nws muaj lub zog siab, kub tsis kam, tiv thaiv corrosion, lub teeb yuag thiab lwm yam ntxwv, thiab yog ib qho ntawm cov khoom tseem ceeb hauv kev lag luam tiv thaiv. Muaj ntau daim ntawv thov hauv cov khoom siv mos mos, cov khoom siv dav hlau.
Aramid fibers yog ib qho ntawm thawj lub zog hluavtaws fibers kom tau txais kev lees paub hauv kev lag luam fiber ntau (FRP) kev lag luam. Composite qib para-aramid fibers yog lub teeb yuag, muaj lub zog tshwj xeeb tensile zoo heev, thiab suav tias yog qhov ua tau zoo heev rau kev cuam tshuam thiab puas. Cov ntaub ntawv siv feem ntau suav nrog cov khoom siv hnyav xws li kayaks thiab canoes, dav hlau fuselage panels thiab cov hlab ntsha siab, cov hnab looj tes tiv thaiv, cov tsho tiv thaiv mos txwv thiab lwm yam. Aramid fibers yog siv nrog epoxy lossis vinyl ester resins.
Carbon Fiber Reinforcement
Nrog rau cov ntsiab lus carbon ntau dua 90%, carbon fiber muaj lub zog tensile siab tshaj plaws hauv kev lag luam FRP. Qhov tseeb, nws kuj muaj qhov kev lag luam zoo tshaj plaws compressive thiab flexural zog. Tom qab ua tiav, cov fibers no tau muab tso ua ke los tsim cov carbon fiber reinforcements xws li cov ntaub thiab cov cab. Carbon fiber reinforcement muab lub zog tshwj xeeb thiab nruj nruj, thiab nws feem ntau kim dua lwm cov khoom siv fiber ntau.
Txhawm rau ua kom muaj zog ntawm cov pa roj carbon fiber ntau, nws yuav tsum tau siv nrog epoxy resins thiab tuaj yeem kho tau siv cov txheej txheem lamination. Nws yog zoo haum rau tsheb, marine thiab aerospace daim ntaub ntawv thiab feem ntau siv nyob rau hauv cov khoom ua si.
