Mu bwubatsi n'ibikorwa remezo, harakenewe kwiyongera kubikoresho bishya bifite imbaraga zongerewe imbaraga, ziramba kandi zoroshye. FRP (Fiberglass Reinforced Plastike) imyirondoro yuzuye ni ibintu byinshi byahinduye inganda nibintu bidasanzwe. Iyi ngingo irasesengura ibintu byingenzi nibyiza bya FRP yerekana imyirondoro kandi ikagaragaza uburyo bwagutse bwa porogaramu.
Umwirondoro wa FRP wakozwe hifashishijwe uburyo bwa pultrusion, uburyo bwo gukomeza gukora bwikora butanga ubuziranenge buhoraho nibisohoka neza. Umwirondoro ukorwa mugukurura fibre ikomeza (mubisanzwe fiberglass) ikoresheje ubwogero bwa resin, butera kwinjizwa neza.
Fibre ihita inyuzwa muburyo bushyushye, ikora ibintu muburyo bwifuzwa. Imwe mu nyungu zingenzi za FRP yerekana imyirondoro nimbaraga zabo nziza cyane-ku bipimo. Iyi myirondoro ifite imbaraga zidasanzwe hamwe nuburyo bukomeye mugihe yoroshye cyane kuruta ibikoresho gakondo nkibyuma cyangwa ibiti. Iyi mikorere ntabwo yorohereza ubwikorezi nogushiraho gusa, ahubwo inagira uruhare mubikorwa rusange byingufu zuburyo.
Byongeye kandi, imyirondoro ya FRP ifite imyirondoro myiza yo kwangirika, bigatuma iba nziza mubisabwa ahantu habi cyangwa kwangirika. Bitandukanye nicyuma, FRP ntisaba ubundi buryo bwo gukingira, kugabanya amafaranga yo kubungabunga no kwagura ubuzima bwimiterere. Kugena imiterere ni ikindi kintu cyerekana imiterere ya FRP. Inzira ya pultrusion yemerera gushiraho no gutunganya imyirondoro, bigafasha injeniyeri nabashushanya gukora ibisubizo byihariye kubikorwa byihariye. Ubu buryo bwinshi burafungura amahirwe adashira yinganda nkubwubatsi, ibikorwa remezo, ubwikorezi, ikirere, inyanja n amashanyarazi.
Byongeye kandi, imyirondoro ya FRP ifite imiterere myiza yumuriro wamashanyarazi, bigatuma iba ibikoresho byo guhitamo kubisaba bidasaba. Kuva mumashanyarazi kugeza kuri insulator hamwe na tray ya kabili, fiberglass pultruded profile itanga umutekano kandi wizewe. Ukoresheje flame retardant resin hamwe ninyongeramusaruro, imyirondoro ya FRP irashobora kandi kuba yujuje ibyangombwa bisabwa byo kurinda umuriro, bikarushaho kwaguka gukoreshwa mubice bitandukanye.
Kuva mubintu byubaka kugeza kubiganza, sisitemu yo gusya, urwego hamwe nidirishya ryamadirishya, imyirondoro ya FRP itezimbere imikorere myiza nubushobozi mubikorwa bitandukanye. Birakwiye ko tumenya ko mugihe imyirondoro ya FRP itanga inyungu nyinshi, gutekereza kubishushanyo mbonera, guhitamo ibikoresho, hamwe nisesengura ryubwubatsi nibyingenzi kugirango bikoreshwe neza kandi byubahirize imitwaro yihariye nibikorwa.
Nkuko urwego rwubwubatsi n’ibikorwa remezo rwungukira ku byiza by’ibikoresho bigezweho, imyirondoro ya FRP igaragara nkigihe kizaza cyo gushimangira ibisubizo byubatswe. Nimbaraga zabo zidasanzwe, kurwanya ruswa, gushushanya guhinduka no guhuza muri rusange, iyi myirondoro ituma abajenjeri n'abubatsi basunika imipaka yo guhanga no kubaka ejo hazaza harambye.
Isosiyete yacu nayo ifite ibicuruzwa. Niba ubishaka, ushobora kutwandikira.
