Kukula kwa GFRP kumachokera ku kufunikira kwakukulu kwa zipangizo zatsopano zomwe zimagwira ntchito bwino, zopepuka, zosagwirizana ndi dzimbiri, komanso zogwiritsa ntchito mphamvu zambiri. Ndi chitukuko cha sayansi ya zinthu komanso kupita patsogolo kwa ukadaulo wopanga zinthu, GFRP pang'onopang'ono yakhala ikugwiritsidwa ntchito m'magawo osiyanasiyana. GFRP nthawi zambiri imakhala ndifiberglassndi matrix ya resin. Makamaka, GFRP ili ndi magawo atatu: fiberglass, resin matrix, ndi interfacial agent. Pakati pawo, fiberglass ndi gawo lofunika kwambiri la GFRP. Fiberglass imapangidwa ndi galasi losungunuka ndi kukoka, ndipo gawo lawo lalikulu ndi silicon dioxide (SiO2). Ulusi wagalasi uli ndi ubwino wa mphamvu yayikulu, kukhuthala kochepa, kutentha, ndi kukana dzimbiri kuti upereke mphamvu ndi kuuma kwa zinthuzo. Chachiwiri, matrix ya resin ndi guluu wa GFRP. Ma matrix a resin omwe amagwiritsidwa ntchito kwambiri ndi polyester, epoxy, ndi phenolic resins. Resin matrix ili ndi kumatirira kwabwino, kukana mankhwala, komanso kukana kukhudza kukonza ndikuteteza fiberglass ndi katundu wonyamula. Komano, ma agent a interfacial amachita gawo lofunika kwambiri pakati pa fiberglass ndi resin matrix. Ma agent a interfacial amatha kukonza kumatirira pakati pa fiberglass ndi resin matrix, ndikuwonjezera mphamvu zamakanika ndi kulimba kwa GFRP.
Kupanga kwa GFRP m'mafakitale kumafuna njira zotsatirazi:
(1) Kukonzekera kwa magalasi a fiberglass:Galasi limatenthedwa ndi kusungunuka, ndipo limakonzedwa m'mawonekedwe ndi kukula kosiyanasiyana kwa fiberglass pogwiritsa ntchito njira monga kujambula kapena kupopera.
(2) Kukonza Patsogolo kwa Fiberglass:Kuchiza pamwamba pa fiberglass mwakuthupi kapena mwamankhwala kuti kuwonjezere kuuma kwa pamwamba pake ndikuwonjezera kulimba kwa interfacial.
(3) Kapangidwe ka fiberglass:Gawani fiberglass yokonzedwa kale mu chipangizo chopangira ulusi molingana ndi zofunikira pakupanga kapangidwe kake ka ulusi.
(4) Matrix ya utomoni wokutira:Ikani matrix ya resin mofanana pa fiberglass, ikani ma fiber bundles, ndipo ikani ulusiwo kuti ugwirizane kwathunthu ndi matrix ya resin.
(5) Kuchiritsa:Kuyeretsa matrix ya resin mwa kutentha, kupondereza, kapena kugwiritsa ntchito zinthu zina (monga wothandizira kuyeretsa) kuti apange kapangidwe kolimba kophatikizana.
(6) Pambuyo pa chithandizo:GFRP yochiritsidwayo imachitidwa njira zochiritsira pambuyo pake monga kudula, kupukuta, ndi kupaka utoto kuti ikwaniritse mawonekedwe abwino komanso mawonekedwe ake.
Kuchokera mu njira yokonzekera yomwe ili pamwambapa, zitha kuwoneka kuti mu ndondomeko yaKupanga kwa GFRP, kukonzekera ndi kukonza kwa fiberglass kumatha kusinthidwa malinga ndi zolinga zosiyanasiyana, ma resin matrices osiyanasiyana ogwiritsira ntchito zosiyanasiyana, ndi njira zosiyanasiyana zokonzera pambuyo pake zingagwiritsidwe ntchito kuti apange GFRP yogwiritsira ntchito zosiyanasiyana. Kawirikawiri, GFRP nthawi zambiri imakhala ndi makhalidwe abwino osiyanasiyana, omwe afotokozedwa mwatsatanetsatane pansipa:
(1) Yopepuka:GFRP ili ndi mphamvu yokoka yochepa poyerekeza ndi zipangizo zachitsulo zachikhalidwe, motero ndi yopepuka pang'ono. Izi zimapangitsa kuti ikhale yopindulitsa m'malo ambiri, monga ndege, magalimoto, ndi zida zamasewera, komwe kulemera kwa nyumbayo kungachepe, zomwe zimapangitsa kuti magwiridwe antchito abwino komanso kugwiritsa ntchito bwino mafuta. Pogwiritsa ntchito nyumba zomangira, mtundu wopepuka wa GFRP ukhoza kuchepetsa kulemera kwa nyumba zazitali.
(2) Mphamvu Yaikulu: Zipangizo zolimbikitsidwa ndi magalasi a fiberglassali ndi mphamvu zambiri, makamaka mphamvu zawo zokoka komanso zopindika. Kuphatikiza kwa fiber-reinforced resin matrix ndi fiberglass kumatha kupirira katundu wolemera komanso kupsinjika, kotero zinthuzo zimakhala bwino kwambiri pamakina.
(3) Kukana dzimbiri:GFRP ili ndi kukana dzimbiri bwino ndipo siikhudzidwa ndi zinthu zowononga monga asidi, alkali, ndi madzi amchere. Izi zimapangitsa kuti zinthuzo zikhale zabwino kwambiri m'malo osiyanasiyana ovuta, monga m'munda wa uinjiniya wa m'madzi, zida zamakemikolo, ndi matanki osungiramo zinthu.
(4) Katundu wabwino wotetezera kutentha:GFRP ili ndi mphamvu zabwino zotetezera kutentha ndipo imatha kulekanitsa bwino mphamvu zamagetsi ndi kutentha. Izi zimapangitsa kuti zinthuzi zizigwiritsidwa ntchito kwambiri pakupanga magetsi ndi kutentha, monga kupanga ma circuit board, ma insulation sleeves, ndi zinthu zotetezera kutentha.
(5) Kukana kutentha bwino:GFRP ili ndikukana kutentha kwambirindipo imatha kusunga magwiridwe antchito okhazikika m'malo otentha kwambiri. Izi zimapangitsa kuti igwiritsidwe ntchito kwambiri m'malo opanga ndege, petrochemical, ndi magetsi, monga kupanga masamba a injini ya turbine ya gasi, magawo a uvuni, ndi zida zamagetsi zotenthetsera.
Mwachidule, GFRP ili ndi ubwino wokhala ndi mphamvu zambiri, yopepuka, yolimbana ndi dzimbiri, yoteteza kutentha bwino, komanso yolimbana ndi kutentha. Zinthu zimenezi zimapangitsa kuti ikhale chinthu chogwiritsidwa ntchito kwambiri m'makampani omanga, okonza ndege, magalimoto, magetsi, ndi mankhwala.
