Ibikoresho bikomeza imbaraga ni igice gishyigikira ibicuruzwa bya FRP, ari nabyo bigena imiterere y’ibikoresho byakoreshejwe. Gukoresha ibikoresho bikomeza imbaraga bigira ingaruka ku kugabanya guhindagurika kw’ibicuruzwa no kongera ubushyuhe bwo guhindura ubushyuhe n’imbaraga z’ubushyuhe buke.

Mu gushushanya ibicuruzwa bya FRP, guhitamo ibikoresho byo gushimangira bigomba gusuzuma neza uburyo ibicuruzwa bicungwa, kuko ubwoko, uburyo bwo gushyiramo n'ibikubiye mu bikoresho byo gushimangira bigira ingaruka zikomeye ku mikorere y'ibicuruzwa bya FRP, kandi ahanini ni byo bigena imbaraga za mekanike n'uburyo bwo gukurura bw'ibicuruzwa bya FRP. Imikorere y'ibicuruzwa bya pultruded hakoreshejwe ibikoresho byo gushimangira bitandukanye nayo iratandukanye.

Byongeye kandi, mu gihe cyujuje ibisabwa mu mikorere y'ibicuruzwa mu buryo bwo gushushanya, ikiguzi nacyo kigomba kwitabwaho, kandi ibikoresho byo gushimangira bihendutse bigomba gutoranywa uko bishoboka kose. Muri rusange, kudatoranya imigozi y'ibirahuri ni igiciro gito ugereranyije n'imyenda ya fibre; igiciro cyaimitako y'ibirahure bya fibreiri hasi ugereranyije n'iy'imyenda, kandi ubushobozi bwo kuvoma ni bwiza. , ariko imbaraga ni nke; fibre ya alkali irahendutse ugereranyije n'iy'imyenda idafite alkali, ariko uko ingano ya alkali yiyongera, ubushobozi bwayo bwo kudahangarwa na alkali, kudahangarwa na ruswa, ndetse n'ubushobozi bw'amashanyarazi bizagabanuka.

Ubwoko bw'ibikoresho bikunze gukoreshwa mu gushimangira ni ubu bukurikira:

1. Gutembera mu gikoresho cy'ikirahure kidahinduka

Gukoresha ingano ihamye, idahindukagutemberera mu byuma by'ikirahureishobora kugabanywamo ubwoko butatu: ubudodo buto bukozwe mu busitani, ubudodo butaziguye butagira aho buboheye n'ubudodo butaziguye butagira aho buboheye.

Bitewe n'ubukana budasa bw'imigozi ipfundikiwe, biroroshye kugwa, bigatuma umurongo urekuye ku mpera y'ibikoresho byo gupfundikiza, ibyo bigatuma imikorere igenda neza.

Gutembera mu buryo butaziguye bifite imiterere yo gutembera neza, kwinjira vuba mu buryo bwa resin, n'imiterere myiza y'ibikoresho, bityo inyinshi mu ntembera zitaziguye zikunze gukoreshwa muri iki gihe.

Udupira twometse hamwe ni ingirakamaro mu kunoza imbaraga z'ibicuruzwa, nko gufungana no gufungana mu buryo bw'umwuka. Gufungana mu buryo bw'umubyimba bifite imbaraga nyinshi z'iminyururu miremire ihoraho ndetse n'ubunini bw'iminyururu migufi. Ni ibikoresho bifite ubushyuhe bwinshi, ubushyuhe buke, birwanya ingese, bifite ubushobozi bwo hejuru kandi binoze cyane. Iminyururu imwe ishyirwa mu buryo bwa monofilament, bityo ishobora no kunoza ubwiza bw'ibicuruzwa byashyizwemo. Kuri ubu, udupira twometse hamwe twakoreshejwe cyane mu gihugu no mu mahanga, nk'ubudodo bwo kuzunguruka no kuzunguruka mu myenda yo gushushanya cyangwa iboshye mu nganda. Ishobora gukoreshwa mu gutanga ibikoresho byo gukururana, gukingira, kurinda cyangwa gufunga.

Ibisabwa ku mikorere y'ibirahure bidahindagurika kugira ngo bikoreshwe mu gusohora imyanda:

(1) Nta kintu cyo kurengaho;

(2) Umuvuduko w'umunyuzi uba umeze kimwe;

(3) Guteranya neza;

(4) Ubudahangarwa bwiza bwo kwangirika;

(5) Hari imitwe mike yavunitse, kandi ntabwo byoroshye kuyihindura;

(6) Ishobora kumena neza kandi iterwa vuba na resin;

(7) Ingufu nyinshi n'ubudahangarwa.

2. Umutambara w'ibirahuri bya fibre

Kugira ngo ibikoresho bya FRP bifite imbaraga zihagije zo kuzenguruka, ibikoresho byo gushimangira nk'umugozi waciwe, umugozi ukomeza, umugozi uvanze, n'umwenda w'ubudodo udatoboye bigomba gukoreshwa. Umugozi ukomeza ni kimwe mu bikoresho bikoreshwa cyane muri iki gihe mu gushimangira imigozi y'ikirahure. Kugira ngo ibicuruzwa birusheho kugaragara neza,umutako wo hejururimwe na rimwe ikoreshwa.

Umugozi ukomeza ugizwe n'imigozi myinshi y'ibirahuri ikomeza ishyirwa mu ruziga, kandi imigozi ifatanye n'ubudodo. Ubuso bw'umugozi ni icyuma gito gisa n'urupapuro cyakozwe no gushyira imigozi yaciwe mu buryo butunguranye kandi buri kumwe kandi ifatanye n'ubudodo. Ingano y'ubudodo ni 5% kugeza 15%, kandi ubunini ni 0.3 kugeza 0.4 mm. Ishobora gutuma ubuso bw'umugozi burushaho kuba bwiza kandi bunoze, kandi ikongera ubushobozi bwo kudasaza bw'umugozi.

Ibiranga umugozi w'ibirahuri ni ibi bikurikira: gupfuka neza, byoroshye kuwuzuzamo resin, kole nyinshi

Ibisabwa mu gikorwa cyo gusohora imirasire y'ikirahure:

(1) Ifite imbaraga nyinshi za mekanike

(2) Ku matike aciwe hakoreshejwe imiti, umugozi ugomba kuba urwanya ingaruka za shimi n'ubushyuhe mu gihe cyo kwinjizwa no gutegurwa mbere kugira ngo ugire imbaraga zihagije mu gihe cyo kurema;

(3) Ishobora gutose neza;

(4) Imitwe idafite uburibwe bwinshi kandi ivunitse buhoro.

3. Umupira wo hejuru w'umugozi wa polyester

Fibre ya polyester ni ubwoko bushya bw'ibikoresho byo kongera imbaraga mu nganda zikora impuzankano. Hari ibicuruzwa byitwa Nexus muri Leta Zunze Ubumwe za Amerika, bikoreshwa cyane mu bicuruzwa bikozwe muri impuzankano kugira ngo bisimbuzeimitako yo hejuru y'ibirahureIfite ingaruka nziza kandi ihendutse. Imaze imyaka irenga 10 ikoreshwa neza.

Ibyiza byo gukoresha agatambaro k'imitako ya polyester:

(1) Bishobora kunoza ubudahangarwa bw'ingaruka, ubudahangarwa bw'ingese n'ubudahangarwa bw'ikirere bw'ibicuruzwa;

(2) Bishobora kunoza imiterere y'ubuso bw'igicuruzwa no gutuma ubuso bw'igicuruzwa burushaho kuba bwiza;

(3) Imiterere n'ubushobozi bwo gukurura by'urusobe rw'ibirahuri bya polyester ni byiza cyane kurusha urusobe rw'ibirahuri bya C, kandi ntabwo byoroshye kumena impande mu gihe cyo gusohora ibirahuri, bigabanya impanuka zo guparika;

(4) Umuvuduko wo gusohora ushobora kongerwa;

(5) Bishobora kugabanya kwangirika kw'ibumba no kunoza igihe cyo gukora kw'ibumba

4. Kaseti y'igitambaro cy'ikirahure

Mu bicuruzwa bimwe na bimwe byihariye byakozwe mu buryo bwa pultruded, kugira ngo huzuzwe ibisabwa mu mikorere yihariye, igitambaro cy'ikirahure gifite ubugari buhamye n'ubugari buri munsi ya mm 0.2 kirakoreshwa, kandi imbaraga zacyo zo gukurura n'imbaraga zo kuzenguruka ni byiza cyane.

5. Gukoresha imyenda ifite imiterere ibiri n'imitako itatu

Imiterere y’ibikoresho bivanze bya pultruded irahindagurika, kandi gukoresha uburyo bwo kuboha impande ebyiri byongera imbaraga n’ubudahangarwa bw’ibikoresho bivanze.

Imigozi yo kugorora n'iyo kugorora by'uyu mwenda iboshywe ntabwo ifatanye, ahubwo ifatanye n'ikindi gikoresho cyo kuboshye, bityo bitandukanye rwose n'igitambaro gisanzwe cy'ikirahure. Imigozi yo muri buri cyerekezo iba iri mu buryo bwa collimated kandi ntabwo ikora ipfundo ryose, bityo imbaraga n'ubukana bw'igicuruzwa cyapfundikiye, biruta cyane iby'igikoresho cyometseho gikozwe mu buryo bukomeza.

Kuri ubu, ikoranabuhanga ryo kuboha mu buryo butatu ryabaye urwego rwo guteza imbere ikoranabuhanga rikurura kandi rikora cyane mu nganda z’ibikoresho bivanze. Dukurikije ibisabwa ku mutwaro, fibre yongerera imbaraga ibohwa mu buryo butaziguye mu nyubako ifite imiterere y’ibice bitatu, kandi imiterere yayo ni imwe n’iy’ibicuruzwa bivanze bigize. Igitambaro cy’uburyo butatu gikoreshwa mu nzira yo kugabanya ubukana bw’ibicuruzwa bivanze mu buryo busanzwe. Gifite ingaruka mbi zo kudakura no kudakura neza, kandi imikorere yacyo yo hagati y’ibice ni myiza cyane.
