Lisebelisoa tse kopantsoeng tsa polymer e matlafalitsoeng ka khalase (GFRP)li tloaelehile kahong hobane li na le karolelano e phahameng ea matla ho ea boima, ha li na mafome, 'me li na le mekhoa e mengata ea ho li sebetsana.

Qalong, GFRP e atisa ho sebelisoa kahong ea sebele ho theha likarolo tsa mantlha tse tšehetsang mojaro joalo ka maballo le likholomo, le liphanele tsa fatše. Tšebeliso ea lipaterone tsa faeba ea khalase ea axial e mengata hammoho le li-resin tse feto-fetohang e lumella likarolo tsa GFRP ho fana ka matla a ikhethang a ho tsikinyeha le ho kobeha. Mohlala, maballo a matlafalitsoeng ka GFRP a ka fokotsa litekanyo tsa karolo e tšekaletseng ha a ntse a boloka bokhoni ba ho jara mojaro oa sebopeho, ka hona a eketsa sebaka se ka sebelisoang sa kahare. Meahong ea fatše, thepa e ntle ea ho kobeha ea maqephe a GFRP e ka ntlafatsa ho tiea ha sebopeho, ea fokotsa ho fapoha ha bolelele ba nako, le ho lelefatsa bophelo ba ts'ebeletso.

Taba ea bobeli, indastering ea kaho, GFRP e ntse e nkela matlafatso ea tšepe ea setso sebaka butle-butle ho ntlafatsa ho tšoarella ha sebopeho le ho hanyetsa mafome. Matlafatso ea tšepe ea setso e senyeha habonolo libakeng tse mongobo, tse fafalitsoeng ka letsoai, kapa tsa lik'hemik'hale, ha GFRP e bontša ho hanyetsa mafome ho hoholo. Liteko li bontša hore esita le libakeng tse nang le letsoai le lengata,GFRPe boloka matla a eona a fetang 90% kamora lihora tse 1000 tsa teko e potlakileng ea mafome. Sena se etsa hore GFRP e be thepa ea bohlokoa ea sebopeho marokhong a lebopong la leoatle, liemelong tsa kou le lifemeng tsa indasteri. Ho feta moo, coefficient ea GFRP ea katoloso ea mocheso e batla e tšoana le ea konkreite, e thibelang khatello ea maikutlo ka lebaka la liphetoho tsa mocheso le ho atolosa nako eohle ea bophelo ea meaho ea konkreite.

Likarolo tsa GFRP le tsona li sebelisoa haholo libakeng tse senyang haholo, joalo ka metheo ea litanka lifemeng tsa lik'hemik'hale, metheo ea lipolatefomo tsa leoatle, le mabota a matamo lifemeng tsa metsi a litšila. Libaka tsena li hlaseloa ke maemo a holimo a li-acid, metheo le lintho tse ling tse senyang ka nako e telele. Le hoja thepa e tloaelehileng e bola habonolo, GFRP e batla e sa kenngoe ke lik'hemik'hale. Lipalopalo li bontša hore kamora ho pepesehela tharollo ea asiti likhoeli tse 6, ka pH ea 3, GFRP e tla ba le 95% ea matla a eona a pele a ho kobeha, ka hona e fana ka tiisetso ea nako e telele ho meaho e libakeng tse mabifi le litšenyehelo tse tlase tsa tlhokomelo le ho nkela sebaka. Meralo ea motheo e tsofetseng le eona e hloka ho lokisoa le ho matlafatsoa, ​​joalo ka marokho a mangata a litsela le mehaho ea thepa. GFRP ke thepa e phethahetseng ea ho matlafatsa hobane e matla, e bobebe, 'me e tlamahanya hantle le konkreite. Mererong ea ho matlafatsa borokho, karolo ea khatello ea libalaka hangata e khomaretsoa ka maqephe a GFRP ho a matlafatsa ha a kobeha. Libalaka tsa konkreite tse matlafalitsoeng tsa GFRP li ka matlafatsoa ho fihlela ho 20-50%. Litokisong tsa lithanele, lihlahisoa tsa letlooeng la GFRP li sebelisoa ho matlafatsa lefika le potolohileng le ho le etsa hore le tsitse haholoanyane le ho hanela ho beola. Ho kenngoa ha lera la GFRP ho potlakile 'me ha ho sitise sebopeho se seng se ntse se le teng haholo kahoo ho loketse litokiso tsa tšohanyetso tsa mehaho ea khale le marokho.

Qetellong, boenjiniere ba borokho le lithanele, bakeng sa marokho a khale, a koahelang bokaholimo ba likarolo tse jarang mojaro kaMaqephe kapa lipoleiti tsa GFRP, ho sebelisa resin e khethehileng ea epoxy bakeng sa ho kopanya ka matla, ho ka ntlafatsa bokhoni ba ho jara mojaro le ho liehisa ts'ebetso ea botsofali ba sebopeho. Boenjiniere ba kotopo, li-grid tsa GFRP li sebetsa 'moho le konkreite ho theha sebopeho se kopaneng sa tšehetso, e leng se ntlafatsang ka katleho khanyetso ea ho kuta ha kotopo le botsitso ba nako e telele, haholo-holo libakeng tse kotsing ea litšisinyeho tsa lefatše.
