Nts'etsopele ea GFRP e bakoa ke tlhokahalo e ntseng e eketseha ea lisebelisoa tse ncha tse sebetsang hantle, tse bobebe ka boima ba 'mele, tse hanyetsanang le ho bola, le tse baballang matla. Ka nts'etsopele ea mahlale a lintho tse bonahalang le ntlafatso e tsoelang pele ea thekenoloji ea tlhahiso, GFRP butle-butle e fumane mefuta e mengata ea likopo mafapheng a fapaneng.GFRP ka kakaretso e na lefiberglassle matrix a resin. Haholo-holo, GFRP e na le likarolo tse tharo: fiberglass, matrix ea resin, le moemeli oa sefahleho. Har'a bona, fiberglass ke karolo ea bohlokoa ea GFRP. Fiberglass e entsoe ka ho qhibiliha le ho taka likhalase, 'me karolo ea tsona e kholo ke silicon dioxide (SiO2). Lithapo tsa khalase li na le melemo ea matla a phahameng, boima bo tlase, mocheso le ho hanyetsa ho bola ho fana ka matla le ho tiea ha thepa. Ea bobeli, matrix a resin ke sekhomaretsi sa GFRP. Li-matrices tse sebelisoang hangata li kenyelletsa polyester, epoxy, le li-phenolic resin. Resin matrix e na le ho khomarela hantle, khanyetso ea lik'hemik'hale, le ho hanyetsa tšusumetso ho lokisa le ho sireletsa fiberglass le meroalo ea ho fetisa. Ka lehlakoreng le leng, li-interfacial agents li phetha karolo ea bohlokoa lipakeng tsa fiberglass le resin matrix. Li-interface agents li ka ntlafatsa ho khomarela pakeng tsa fiberglass le resin matrix, le ho ntlafatsa thepa ea mochine le ho tšoarella ha GFRP.
Kakaretso ea indasteri ea GFRP e hloka mehato e latelang:
(1) Ho lokisa fiberglass:Thepa ea khalase ea futhumatsa le ho qhibiliha, 'me e lokisoa ka libopeho le boholo bo fapaneng ba fiberglass ka mekhoa e kang ho taka kapa ho fafatsa.
(2) Fiberglass Pretreatment:Phekolo ea 'mele kapa ea lik'hemik'hale ea khalase ea fiberglass ho eketsa bohloeki ba bona le ho ntlafatsa ho khomarela sefahleho.
(3) Tlhophiso ea fiberglass:Abela khalase ea fiber e entsoeng esale pele ka har'a lisebelisoa tsa ho bopa ho latela litlhoko tsa moralo ho theha sebopeho se reriloeng esale pele.
(4) Ho roala matrix a resin:Apesa matrix a resin ka mokhoa o ts'oanang holim'a khalase ea fiber, e kenngoe ka har'a marako a fiber, 'me u behe likhoele ka botlalo le matrix a resin.
(5) Ho folisa:Ho phekola matrix a resin ka ho futhumatsa, ho hatella, kapa ho sebelisa lisebelisoa tse tlatselletsang (mohlala, pheko) ho theha sebopeho se matla sa motsoako.
(6) Kalafo ka morao:GFRP e folisitsoeng e tlas'a mekhoa ea ka mor'a phekolo e kang ho kuta, ho bentša, le ho penta ho finyella boleng ba ho qetela ba boleng le litlhoko tsa ponahalo.
Ho tsoa ts'ebetsong ea ho itokisa ka holimo, ho ka bonoa hore ts'ebetsong eaTlhahiso ea GFRP, ho lokisoa le ho hlophisoa ha fiberglass ho ka fetoloa ho ea ka merero e fapaneng ea ts'ebetso, matrices a fapaneng a resin bakeng sa likopo tse fapaneng, le mekhoa e fapaneng ea ho sebetsa ka morao e ka sebelisoa ho finyella tlhahiso ea GFRP bakeng sa likopo tse fapaneng. Ka kakaretso, GFRP hangata e na le mefuta e fapaneng ea thepa e ntle, e hlalositsoeng ka botlalo ka tlase:
(1) E bobebe:GFRP e na le matla a khoheli a tlase ha a bapisoa le lisebelisoa tsa tšepe tsa setso, 'me ka hona e batla e le bobebe. Sena se etsa hore e be molemo libakeng tse ngata, tse kang sefofane, likoloi le thepa ea lipapali, moo boima ba mohaho bo ka fokotsoang, ho fella ka ts'ebetso e ntlafetseng le ho sebetsa hantle ha mafura. E sebelisoa ho mehaho ea mohaho, tlhaho e bobebe ea GFRP e ka fokotsa ka katleho boima ba mehaho e phahameng.
(2) Matla a Phahameng: Lisebelisoa tse matlafalitsoeng ka fiberglassba na le matla a phahameng, haholo-holo matla a bona a ho tsitsipana le a flexural. Motsoako oa fiber-reinforced resin matrix le fiberglass e ka mamella meroalo e meholo le likhatello, ka hona, thepa e sebetsa hantle ka thepa ea mochini.
(3) Corrosion resistance:GFRP e na le khanyetso e ntle ea kutu 'me ha e ts'oaroe habonolo ke mecha ea litaba e senyang joalo ka asiti, alkali le metsi a letsoai. Sena se etsa hore thepa e libakeng tse fapaneng tse thata e be molemo o moholo, joalo ka lefapheng la boenjiniere ba metsing, lisebelisoa tsa lik'hemik'hale le litanka tsa polokelo.
(4) Lintho tse ntle tsa insulating:GFRP e na le thepa e sireletsang hantle 'me e khona ho arola hantle motlakase oa motlakase le mocheso oa motlakase. Sena se etsa hore thepa e sebelisoe haholo lefapheng la boenjiniere ba motlakase le ho itšehla thajana ka mocheso, joalo ka ho etsa liboto tsa potoloho, li-sleeve tse sireletsang, le lisebelisoa tsa ho itšehla thajana.
(5) Ho hanyetsa mocheso o motle:GFRP e na leho hanyetsa mocheso o phahamengmme e khona ho boloka ts'ebetso e tsitsitseng libakeng tse phahameng tsa mocheso. Sena se e etsa hore e sebelisoe haholo libakeng tsa aerospace, petrochemical, le matla a ho fehla matla, joalo ka ho etsa mahare a enjene ea turbine ea khase, likarolo tsa sebōpi, le lisebelisoa tsa lisebelisoa tsa feme ea motlakase.
Ka kakaretso, GFRP e na le melemo ea matla a phahameng, boima bo bobebe, ho hanyetsa kutu, thepa e ntle ea ho itšireletsa le ho hanyetsa mocheso. Mehaho ena e etsa hore e sebelisoe haholo indastering ea kaho, ea sefofane, ea likoloi, ea matla le ea lik'hemik'hale.
