Ukuthuthukiswa kweziqu ze-GFRP kusuka esifungweni esandayo sezinto ezintsha ezenziwayo eziphakeme, kukhanya isisindo, ukumelana nokugqwala okwengeziwe, kanye namandla amaningi. Ngokuthuthukiswa kwesayensi yezinto ezibonakalayo kanye nokwenza ngcono okuqhubekayo kobuchwepheshe bokukhiqiza, kancane kancane i-GFRS ithole izicelo eziningi ezinhlobonhlobo ezinhlelweni ezahlukahlukene.GFRP ngokuvamile ziquketheijibhakanye ne-resin matrix. Ngokukhethekile, i-Gffrp ihlanganisa izingxenye ezintathu: I-Fiberglass, i-resin matrix, kanye ne-ejenti yokuhlangana. Phakathi kwazo, i-fiberglass iyingxenye ebalulekile ye-GFRP. I-fiberglass yenziwa ngokuncibilika nokudweba ingilazi, futhi ingxenye yazo eyinhloko yi-silicon dioxide (Sio2). I-Glass Fibers inezinzuzo zamandla aphezulu, ukuqina okuphansi, ukushisa nokugqwala ukumelana ukuze kunikeze amandla nokuqina kokuqina. Okwesibili, i-resin matrix iyinhlangano yokunamathela kwe-GFRP. Ama-matric asetshenziswa kaningi ama-resin afaka i-polyester, epoxy, kanye ne-phenolic resins. I-Resin Matrix inama-adrix amahle, ukumelana kwamakhemikhali, kanye nokumelana nomthelela ukulungisa nokuvikela i-fiberglass kanye nokudlulisela imithwalo. Ngakolunye uhlangothi, ama-ejenti ahlukahlukene, ngakolunye uhlangothi, adlala indima ebalulekile phakathi kwe-fiberglass ne-resin matrix. Ama-ejenti ahlukahlukene angathuthukisa ukunamathela phakathi kwe-fiberglass ne-resin matrix, futhi athuthukise izakhiwo zemishini nokuqina kwe-GFRP.
I-General Industrial Synthesis ye-GFRP idinga lezi zinyathelo ezilandelayo:
(1) Ukulungiselela kwe-fiberglass:Izinto ezibonakalayo zifudumele futhi zincibilike, futhi zilungiselelwe zobumo nobukhulu be-fiberglass ngezindlela ezifana nokudweba noma ukufafaza.
(2) Ukuncishiswa kwe-fiberglass:Ukwelashwa komhlaba okungokomzimba noma kwamakhemikhali kwe-fiberglass ukwandisa ubulukhuni sabo futhi kuthuthukise adhesion anfacial.
(3) Ukuhlelwa kwe-fiberglass:Sabalalisa i-fiberglass ephethwe ngaphambilini kwizinto zokubumba ngokuya ngezidingo zokwakhiwa ukuze wakhe isakhiwo se-fiber mederetered.
(4) I-Resin Resin Matrix:Bopha i-matrix ye-resin efanayo ku-fiberglass, faka ama-fiber bundles, bese ubeka imicu ngokuxhumana ngokugcwele ne-resin matrix.
(5) Ukwelapha:Ukwelapha i-resin matrix ngokushisa, ukucindezela, noma ukusebenzisa izinto ezisizayo (isib. Ukwelapha i-ejenti) ukwakha isakhiwo esiyinhlanganisela esiqinile.
(6) Ukwelashwa kwangemva kwalokho:I-GFRS ephethwe ngayo inqubekela phambili yokwelashwa okunjenge-trimming, polishing, nokupenda ukufeza ikhwalithi yokugcina yekhwalithi kanye nezidingo zokubukeka.
Kusuka kwinqubo engenhla kokulungiselela, kungabonakala lokho kwinqubo yeUkukhiqizwa kwe-Gfrp, Ukulungiswa kanye nokuhlelwa kwe-fiberglass kungashintshwa ngokuya ngezinhloso ezahlukahlukene zenqubo, ama-matric ahlukene we-resin wezicelo ezahlukahlukene, futhi izindlela ezahlukahlukene zokufaka azosetshenziselwa ukufeza ukukhiqizwa kwe-GFRS kwezicelo ezahlukahlukene. Ngokuvamile, i-GFRP imvamisa inezakhiwo eziningi ezinhle, ezichazwe ngokuningiliziwe ngezansi:
(1) Engasindi:I-GFRP inamandla aphansi aphansi ngokuqhathaniswa nezinto zokwenziwa zensimbi yendabuko, futhi ngenxa yalokho ingasindi. Lokhu kwenza kube yinzuzo ezindaweni eziningi, njenge-aerospace, izimoto, nemishini yezemidlalo, lapho isisindo esifile sesakhiwo singancishiswa khona, okuphumela ekusebenzeni kahle nasekusebenzeni kahle kophethiloli. Kusetshenziswe ekwakheni izakhiwo, uhlobo olungasindi lwe-GFRP lunganciphisa ngempumelelo isisindo sezakhiwo eziphakeme kakhulu.
(2) Amandla aphezulu: Izinto eziqinisiwe ze-fiberglassIba namandla aphezulu, ikakhulukazi amandla abo ashubile futhi aguqukayo. Inhlanganisela ye-resin matrix eqinisiwe ye-fiber
(3) Ukumelana nokugqwala:I-GFRP inokumelana kahle nokugqwala okuhle futhi ayitholwanga imidiya ebonakalayo efana ne-acid, alkali kanye namanzi kasawoti. Lokhu kwenza okuqukethwe ezindaweni ezahlukahlukene ezinokhahlo kube yinzuzo enkulu, njengasensimini yobunjiniyela bakwaMarine, imishini yamakhemikhali namathangi okugcina.
(4) Izakhiwo ezinhle zokufaka okufaka:I-GFRP inezakhiwo ezinhle zokufaka amandla futhi ingahlukanisa ngempumelelo i-electromagnetic kanye ne-thermal energy conduction. Lokhu kwenza lokho kusetshenziswe kabanzi emkhakheni wobunjiniyela kagesi kanye nokuhlukaniswa okushisayo, njengokukhiqizwa kwamabhodi wesifunda, imikhono efaka ukufakwa kwezindawo, kanye nezinto zokwehlukaniswa okushisayo.
(5) Ukumelana nokushisa okuhle:I-GFRP inayoUkumelana nokushisa okuphezulufuthi iyakwazi ukugcina ukusebenza okuzinzile ezindaweni ezishisa kakhulu. Lokhu kwenza ukuthi isetshenziswe kabanzi e-aerospace, ama-petrochemical, kanye namandla okuphekelanga amandla amasimu, njengokukhiqizwa kwe-turbine injini ama-blades, ukwahlukaniswa kwezimpahla zomlilo, kanye nezinto zokutshala izitshalo ezingama-thermal.
Ngamafuphi, i-GFRP inezinzuzo zamandla aphezulu, ezingasindi, ukumelana nokugqwala, izakhiwo ezinhle ezifaka ukubekezela, nokumelana nokushisa. Lezi zakhiwo zikwenza kube yinto esetshenziswe kabanzi ekwakheni, i-aerospace, ezenzakalelayo, amandla, kanye nezimboni zamakhemikhali.
