Kev txhim kho ntawm GFR cov kav ntawm qhov nce ntxiv rau cov ntaub ntawv tshiab uas tau ua ntau dua, kev tiv taus ntau dua, ntau lub zog ua kom muaj zog. Nrog rau kev txhim kho ntawm cov khoom siv science thiab kev txhim kho txuas ntxiv ntawm kev tsim khoom siv thev naus laus zis, GRR tau maj mam tau txais ntau thaj chaw hauv ntau thaj teb.GFRP feem ntau muajiav yasthiab ib tug resin matrix. Tshwj xeeb, gfrp muaj peb ntu: fiberglass, Resin Matrix, thiab Interfacial tus neeg sawv cev. Ntawm lawv, fiberglass yog ib feem tseem ceeb ntawm GFR. Fiberglass tau ua los ntawm melting thiab kos duab iav, thiab lawv lub ntsiab sib xyaw yog silicon dioxide (sio2). Cov iav fibers muaj qhov zoo ntawm lub zog siab, ceev, cua sov, thiab corrosion tsis kam muab lub zog thiab txhav rau cov khoom siv. Thib ob, resin matrix yog cov nplaum rau GFR. Feem ntau siv resin matrices suav nrog Polyester, Epoxy, thiab Phenolic Resins. Resin Matrix muaj cov nplaum zoo, tshuaj lom neeg kuj, thiab cuam tshuam kev cuam tshuam los kho thiab tiv thaiv cov fiberglass thiab hloov chaw. Interfacial tus sawv cev, ntawm qhov tod tes, ua si lub luag haujlwm tseem ceeb ntawm fiberglass thiab Resin Matrix. Cov neeg sawv cev sib txuam tuaj yeem txhim kho cov nplaum ntawm fiberglass thiab Resin Matrix, thiab txhim kho cov cuab yeej siv kho tshuab thiab ruaj khov ntawm GFR.
Kev lag luam Industrial synthesis ntawm GFRP xav tau cov kauj ruam hauv qab no:
(1) Fiberglass npaj:Cov khoom siv iav yog rhuab thiab melted, thiab npaj rau hauv cov duab sib txawv thiab ntau thiab tsawg ntawm cov hau kev los ntawm kev kos duab lossis tshuaj tsuag.
(2) fiberglass pretreatment:Kev kho mob lub cev lossis tshuaj lom neeg ntawm cov fiberglass kom nce lawv qhov kev npau taws thiab txhim kho interfacial.
(3) Kev saib xyuas cov fiberglass:Muab faib cov khoom ua ntej fiberglass hauv molding appripatus raws li cov qauv yuav tsum tau ua tus qauv fiber ntau.
(4) Txheej Resin Matrix:Tsho Resin matrix uniformly ntawm cov fiberglass, impregnate cov fiber ntau, thiab muab cov fiberers nyob rau hauv tag nrho kev sib cuag nrog lub resin matrix.
(5) Kho:Kho lub resin matrix los ntawm cua sov, nias, lossis siv cov ntaub ntawv uas siv (piv txwv li tus tshuaj tiv thaiv) los ua tus qauv muaj zog.
(6) post-kho:Cov txheej txheem kho GFRP yog raug rau cov txheej txheem kev kho mob tom qab xws li trimming, polishing, thiab pleev xim kom ua tiav qhov zoo kawg nkaus thiab tsos xav tau.
Los ntawm cov txheej txheem npaj saum toj no, nws tuaj yeem pom tau tias nyob rau hauv tus txheej txheem ntawmGFP Ntau Lawm, kev npaj thiab kev npaj ntawm fiberglass tuaj yeem hloov kho raws li cov txheej txheem sib txawv, cov txheej txheem tom qab sib txawv tuaj yeem siv kom ua tiav cov kev siv GFR rau cov ntawv thov sib txawv. Feem ntau, GFRP feem ntau muaj ntau yam khoom zoo, uas tau piav qhia hauv kev nthuav dav hauv qab no:
(1) lub teeb yuag:GFRP muaj qhov tsis tshua muaj lub ntiajteb txawj nqus piv rau cov khoom siv tsoos hlau, thiab yog li ntawd tus kheej lub teeb yuag. Qhov no ua rau nws ua tau zoo nyob rau ntau thaj chaw, xws li aerospace, tsheb, thiab cov khoom siv kis las, uas tus neeg tuag tau kev ua tau zoo thiab roj ua tau zoo. Ua ntawv thov rau tsev qauv qauv, lub teeb yuag ntawm GFRP tuaj yeem txo qis qhov hnyav ntawm cov tuam tsev siab.
(2) lub zog siab: Cov ntaub ntawv fiberglass-reasfieldMuaj lub zog siab, tshwj xeeb tshaj yog lawv lub tensile thiab flexural zog. Kev sib xyaw ntawm fiber ntau txhawb nqa cov ntaub so thiab cov fiberglass tuaj yeem tiv thaiv cov nra loj thiab kev ntxhov siab loj, yog li cov khoom siv tau zoo nyob rau hauv cov khoom siv mechanical.
(3) Corrosion Kuj:GFR tau zoo heev corrosion tsis kam thiab tsis muaj kev cuam tshuam rau kev tawm tswv yim xws li kua qaub, cov dej alkali. This makes the material in a variety of harsh environments a great advantage, such as in the field of marine engineering, chemical equipment, and storage tanks.
(4) insulating cov khoom lag luam:GFRP muaj cov khoom insulating zoo thiab tuaj yeem zoo cais cov hluav taws xob thiab cua sov lub zog conduction. Qhov no ua rau cov khoom siv dav hauv cov hluav taws xob engineering thiab cov cua sov cody, xws li kev tsim cov khoom siv hluav taws xob, insulating cov ntaub ntawv, thiab thermal rho tawm cov ntaub ntawv.
(5) Cov Hluav Taws Kub Zoo:GFR tauKev tiv thaiv kubThiab muaj peev xwm tswj tau ruaj khov ua tau zoo nyob hauv ib puag ncig kub. Qhov no ua rau nws dav siv nyob rau hauv aerospace, thiab lub zog loj heev, xws li tsim cov khoom siv roj purbine, cua cub paus ntau, thiab thermal fais fab cog khoom siv.
Hauv cov ntsiab lus, GFRP muaj qhov zoo ntawm lub zog siab, lub teeb ci, corrosion defitance, zoo insulating zog, thiab cua sov ua kom tsis kam. Cov khoom no ua rau nws siv cov khoom siv dav siv hauv kev tsim kho, Aerospace, fais fab, muaj zog, thiab kev lag luam siv tshuaj.
