Txoj kev loj hlob ntawm GFRP yog los ntawm kev xav tau ntawm cov ntaub ntawv tshiab uas ua tau zoo dua, sib dua hauv qhov hnyav, tiv taus corrosion, thiab muaj zog ntau dua. Nrog rau kev txhim kho ntawm cov ntaub ntawv tshawb fawb thiab kev txhim kho txuas ntxiv ntawm kev tsim cov thev naus laus zis, GFRP tau maj mam tau txais ntau yam kev siv hauv ntau qhov chaw.GFRP feem ntau muajfiberglassthiab resin matrix. Tshwj xeeb, GFRP muaj peb ntu: fiberglass, resin matrix, thiab interfacial agent. Ntawm lawv, fiberglass yog ib feem tseem ceeb ntawm GFRP. Fiberglass yog tsim los ntawm melting thiab kos duab iav, thiab lawv cov khoom tseem ceeb yog silicon dioxide (SiO2). Cov iav fibers muaj qhov zoo ntawm lub zog siab, tsis tshua muaj siab, kub, thiab corrosion kuj los muab lub zog thiab nruj rau cov khoom. Qhov thib ob, cov resin matrix yog cov nplaum rau GFRP. Feem ntau siv resin matrices muaj xws li polyester, epoxy, thiab phenolic resins. Resin matrix muaj qhov adhesion zoo, tshuaj tiv thaiv, thiab kev cuam tshuam los txhim kho thiab tiv thaiv fiberglass thiab hloov chaw. Interfacial agents, ntawm qhov tod tes, ua lub luag haujlwm tseem ceeb ntawm fiberglass thiab resin matrix. Interfacial agents tuaj yeem txhim kho qhov adhesion ntawm fiberglass thiab resin matrix, thiab txhim kho cov khoom siv dag zog thiab ua haujlwm ntev ntawm GFRP.
General industrial synthesis ntawm GFRP yuav tsum muaj cov kauj ruam hauv qab no:
(1) Fiberglass npaj:Cov khoom siv iav yog rhuab thiab yaj, thiab npaj rau hauv cov duab sib txawv thiab qhov ntau thiab tsawg ntawm fiberglass los ntawm txoj kev xws li kos duab lossis txau.
(2) Fiberglass Pretreatment:Kev kho lub cev lossis tshuaj kho qhov chaw ntawm fiberglass kom lawv cov roughness thiab txhim kho interfacial adhesion.
(3) Kev npaj ntawm fiberglass:Muab cov fiberglass pre-treated nyob rau hauv lub molding apparatus raws li tus tsim yuav tsum tau tsim ib tug predetermined fiber ntau npaj qauv.
(4) Txheej resin matrix:Coated cov resin matrix uniformly ntawm lub fiberglass, impregnate lub fiber bundles, thiab muab cov fibers nyob rau hauv tag nrho kev sib cuag nrog cov cob matrix.
(5) Kev tsim kho:Kho cov resin matrix los ntawm cua sov, pressurizing, los yog siv auxiliary cov ntaub ntawv (xws li curing agent) los tsim ib tug muaj zog composite qauv.
(6) Kev kho mob tom qab:GFRP kho tau raug rau cov txheej txheem tom qab kev kho mob xws li trimming, polishing, thiab pleev xim kom ua tiav qhov kawg ntawm qhov zoo thiab qhov yuav tsum tau ua.
Los ntawm cov txheej txheem kev npaj saum toj no, nws tuaj yeem pom tias nyob rau hauv tus txheej txheem ntawmGFRP ntau lawm, kev npaj thiab kev npaj ntawm fiberglass tuaj yeem hloov kho raws li cov txheej txheem sib txawv, sib txawv resin matrices rau kev siv sib txawv, thiab cov txheej txheem tom qab sib txawv tuaj yeem siv los ua kom tiav cov khoom ntawm GFRP rau ntau daim ntawv thov. Feem ntau, GFRP feem ntau muaj ntau yam khoom zoo, uas tau piav qhia hauv qab no:
(1) Lub teeb nyhav:GFRP muaj qhov sib nqus tshwj xeeb piv rau cov khoom siv hlau tsoos, thiab yog li ntawd kuj sib sib zog nqus. Qhov no ua rau nws muaj txiaj ntsig zoo hauv ntau thaj chaw, xws li aerospace, tsheb, thiab cov khoom siv ua kis las, qhov twg qhov hnyav ntawm cov qauv tuaj yeem txo qis, ua rau kev txhim kho kev ua haujlwm thiab kev siv roj. Siv rau cov qauv tsim, lub teeb hnyav ntawm GFRP tuaj yeem txo qhov hnyav ntawm cov tsev siab.
(2) Siab zog: Fiberglass-reinforced cov ntaub ntawvmuaj lub zog siab, tshwj xeeb tshaj yog lawv lub zog tensile thiab flexural. Kev sib xyaw ua ke ntawm cov khoom siv fiber ntau ntxiv cov matrix thiab fiberglass tuaj yeem tiv taus cov khoom loj thiab kev ntxhov siab, yog li cov khoom siv tau zoo hauv cov khoom siv kho tshuab.
(3) Corrosion kuj:GFRP muaj kev tiv thaiv corrosion zoo heev thiab tsis cuam tshuam rau corrosive media xws li kua qaub, alkali, thiab dej ntsev. Qhov no ua rau cov khoom siv nyob rau hauv ntau qhov hnyav ib puag ncig muaj txiaj ntsig zoo, xws li hauv kev lag luam marine engineering, cov cuab yeej siv tshuaj, thiab cov tank cia.
(4) Cov khoom zoo insulating:GFRP muaj cov khoom zoo insulating thiab tuaj yeem cais cov electromagnetic thiab thermal zog conduction. Qhov no ua rau cov khoom siv dav siv hauv kev lag luam hluav taws xob engineering thiab thermal rho tawm, xws li kev tsim khoom ntawm Circuit Court boards, insulating lub tes tsho, thiab thermal rho tawm cov ntaub ntawv.
(5) Ua haujlwm kub zoo:GFRP muajsiab kub tsis kamthiab muaj peev xwm tswj tau qhov kev ua haujlwm ruaj khov hauv qhov chaw kub kub. Qhov no ua rau nws siv dav hauv aerospace, petrochemical, thiab lub zog tsim hluav taws xob, xws li kev tsim cov roj turbine cav hniav, rauv partitions, thiab thermal fais fab nroj tsuag cov khoom siv.
Hauv cov ntsiab lus, GFRP muaj qhov zoo ntawm lub zog siab, lub teeb yuag, corrosion kuj, zoo insulating zog, thiab kub tsis kam. Cov khoom no ua rau nws cov khoom siv dav siv hauv kev tsim kho, aerospace, tsheb, fais fab, thiab tshuaj lom neeg kev lag luam.
