1.Ni ubuhe buryo bwa Fibre Fibre optique?
FRPIrashobora kandi kwerekeza kuri fibre ishimangira polymer ikoreshwa mumigozi ya fibre optique. Umugozi wa fibre optique ugizwe nibirahuri cyangwa plastike yohereza amakuru ukoresheje ibimenyetso byoroheje. Kurinda fibre yoroshye no gutanga imbaraga zumukanishi, akenshi zishimangirwa numunyamuryango wimbaraga zo hagati zakozwe na fibre reinforment polymer (FRP) cyangwa ibyuma.
2.Ni gute kuri FRP?
FRP isobanura Fibre Reinforced Polymer, kandi ni ubwoko bwibikoresho bikomatanya bikunze gukoreshwa mumigozi ya fibre optique nkumunyamuryango wimbaraga. FRP itanga ubufasha bwibikoresho kuri kabili, ifasha mukurinda kwangirika kwinzira ya fibre optique imbere yumugozi. FRP ni ibikoresho bikurura insinga ya fibre optique kuko irakomeye, yoroshye, kandi irwanya ruswa nibindi bintu bidukikije. Irashobora kandi kubumbabumbwa muburyo butandukanye no mubunini butandukanye, bigatuma ishobora guhuzwa nurwego runini rwibishushanyo.
3.Ibyiza byo gukoresha FRP mumashanyarazi ya fibre optique
FRP (Fibre Reinforced Polymer) itanga ibyiza byinshi kubikoresho bya fibre.
3.1 Imbaraga
FRP ifite ubucucike bugereranije kuva kuri 1.5 kugeza kuri 2.0, ni kimwe cya kane kugeza kuri kimwe cya gatanu cyicyuma cya karubone. Nubwo bimeze gurtyo, imbaraga zayo zingana ziragereranywa cyangwa zirenze iz'icyuma cya karubone. Ikigeretse kuri ibyo, imbaraga zayo zishobora kugereranywa n’icyuma cyo mu rwego rwo hejuru. FRP itanga imbaraga nyinshi no gukomera, bigatuma iba ibikoresho byiza kubanyamuryango ba kabili. Irashobora gutanga inkunga ikenewe kugirango irinde insinga za fibre imbaraga ziva hanze no gukumira ibyangiritse.
3.2
FRP yoroshye cyane kuruta ibyuma cyangwa ibindi byuma, bishobora kugabanya cyane uburemere bwumugozi wa fibre. Kurugero, insinga isanzwe yicyuma ipima ibiro 0.3-0.4 kumaguru, mugihe umugozi uhwanye na FRP upima ibiro 0.1-0.2 kumaguru. Ibi byoroshe gufata, gutwara, no gushiraho umugozi, cyane cyane mubirere cyangwa byahagaritswe.
3.3 Kurwanya ruswa
FRP irwanya ruswa, ifite akamaro kanini mubidukikije bikaze, nkibikorwa byo mu nyanja cyangwa munsi yubutaka. Irashobora gufasha kurinda insinga ya fibre kwangirika no kongera igihe cyayo. Mu bushakashatsi bwasohotse mu kinyamakuru cya Composites for Construction, ingero za FRP zatewe n’ibidukikije byo mu nyanja byerekanaga ko byangiritse nyuma y’imyaka 20 yo kwerekana
3.4 Kutayobora
FRP ni ibikoresho bitayobora, bivuze ko bishobora gutanga amashanyarazi kumashanyarazi. Ibi nibyingenzi byingenzi mubisabwa aho amashanyarazi ashobora kugira ingaruka kumikorere ya fibre.
3.5 Igishushanyo mbonera
FRP irashobora kubumbabumbwa muburyo butandukanye no mubunini, bishobora kwemerera kubishushanyo mbonera byihariye hamwe nibikoresho bya kabili. Ibi birashobora gufasha kunoza imikorere nimikorere ya fibre.
4.FRP na Steel Imbaraga Abanyamuryango na KFRP muri Fibre Optic Cable
Ibikoresho bitatu bisanzwe bikoreshwa kubanyamuryango mumashanyarazi ya fibre optique ni FRP (Fibre Reinforced Plastike), ibyuma, na KFRP (Kevlar Fibre Reinforced Plastique). Reka tugereranye ibyo bikoresho dukurikije imiterere yabyo.
4.1 Imbaraga no Kuramba
FRP: Abagize imbaraga za FRP bikozwe mubikoresho byinshi nkibirahure cyangwa fibre karubone yashyizwe muri matrise ya plastike. Zitanga imbaraga zingirakamaro kandi ziremereye, zituma zikwiranye nindege. Zirwanya kandi ruswa hamwe n’imiti, bigatuma biramba ahantu habi.
Icyuma: Abagize imbaraga zicyuma bazwiho imbaraga zingana kandi ziramba. Bakunze gukoreshwa mubikoresho byo hanze aho hakenewe imbaraga za mashini nyinshi, kandi birashobora kwihanganira ikirere gikabije. Nyamara, ibyuma biremereye kandi birashobora guhura na ruswa mugihe, bishobora kugira ingaruka kuramba.
KFRP: Abanyamuryango ba KFRP imbaraga zakozwe muri fibre ya Kevlar yashyizwe muri matrise ya plastike. Kevlar izwiho imbaraga zidasanzwe no kuramba, kandi abanyamuryango ba KFRP batanga imbaraga zingana nuburemere buke. KFRP nayo irwanya ruswa hamwe nimiti, bigatuma ibera hanze.
4.2 Guhinduka no koroshya kwishyiriraho
FRP: Abanyamuryango ba FRP biroroshye kandi byoroshye kubyitwaramo, bigatuma biba byiza mugushiraho ahantu hafunganye cyangwa mubihe bikenewe guhinduka. Birashobora kugororwa byoroshye cyangwa kubumbabumbwa kugirango bihuze ibintu bitandukanye byo kwishyiriraho.
Icyuma: Abagize imbaraga zibyuma biragoye kandi ntibihinduka ugereranije na FRP na KFRP. Bashobora gusaba ibikoresho byongeweho cyangwa ibikoresho byo kugunama cyangwa gushushanya mugihe cyo kwishyiriraho, bishobora kongera ubwubatsi bwigihe nigihe.
KFRP: Abagize imbaraga za KFRP biroroshye cyane kandi byoroshye kubyitwaramo, bisa na FRP. Birashobora kugororwa cyangwa gushushanya mugihe cyo kwishyiriraho bidakenewe ibyuma byongeweho, bigatuma byoroha muburyo butandukanye bwo kwishyiriraho.
4.3 Uburemere
FRP: Abanyamuryango ba FRP bafite imbaraga zoroheje, zishobora gufasha kugabanya uburemere rusange bwumugozi wa fibre optique. Ibi bituma bibera mu kirere no mu bihe aho uburemere butekerezwa, nko muri porogaramu zo hejuru.
Icyuma: Imbaraga zicyuma ziraremereye, zishobora kongerera uburemere umugozi wa fibre optique. Ibi ntibishobora kuba byiza mubirere byo mu kirere cyangwa ibihe aho uburemere bugomba kugabanuka.
KFRP: Abanyamuryango ba KFRP bafite imbaraga zoroheje, zisa na FRP, zifasha kugabanya uburemere rusange bwumugozi wa fibre optique. Ibi bituma bakwirakwiza ikirere hamwe nibihe uburemere bwitabwaho.
4.4 Amashanyarazi
FRP: Abanyamuryango ba FRP imbaraga ntibayobora, zishobora gutanga amashanyarazi kumashanyarazi ya fibre optique. Ibi birashobora kuba byiza mugihe aho amashanyarazi agomba kugabanuka.
Icyuma: Abagize imbaraga zibyuma barayobora, bishobora guteza ibyago byo guhagarika amashanyarazi cyangwa ibibazo byubutaka mubikorwa bimwe.
KFRP: Abanyamuryango ba KFRP nabo ntibayobora, basa na FRP, ishobora gutanga amashanyarazi kumashanyarazi ya fibre optique.
4.5 Igiciro
FRP: Abanyamuryango ba FRP imbaraga muri rusange zihendutse ugereranije nicyuma, bigatuma bahitamo neza kubikoresho bya fibre optique.
Icyuma: Abagize ingufu zicyuma barashobora kubahenze ugereranije na FRP cyangwa KFRP bitewe nigiciro cyibikoresho nibindi bikorwa byo gukora bisabwa.
KFRP: Abanyamuryango ba KFRP imbaraga zishobora kuba zihenze gato ugereranije na FRP, ariko ziracyahenze cyane ugereranije nicyuma. Ariko, ikiguzi kirashobora gutandukana bitewe nuwabikoze nu mwanya.
5. Incamake
FRP ikomatanya imbaraga nyinshi, uburemere buke, kurwanya ruswa, hamwe no gukwirakwiza amashanyarazi - bigatuma ihitamo ryizewe rya fibre optique. KuriISI imwe, dutanga ubuziranenge bwa FRP hamwe nurwego rwuzuye rwibikoresho fatizo kugirango dushyigikire umusaruro wawe.
