Muri iki gihe cy’iterambere ryihuse mu ikoranabuhanga, imvange za fibre ya karuboni ziri kwihesha izina mu nzego zitandukanye bitewe n’imikorere yazo myiza. Kuva ku bikorwa byo mu kirere bigezweho kugeza ku byo abantu bakeneye buri munsi mu bikoresho bya siporo, imvange za fibre ya karuboni zagaragaje ubushobozi bukomeye. Ariko, kugira ngo hategurwe imvange za fibre ya karuboni zikora neza, havurwa uburyo bwo gukorainsinga za karubonini intambwe y'ingenzi.
Ishusho ya mikorosikopi ya elegitoroniki y'ubuso bwa fibre ya karuboni
Fibre ya karuboni, fibre ikora neza cyane, ifite imiterere myinshi ishimishije. Igizwe ahanini na karuboni kandi ifite imiterere miremire ya fibre. Ukurikije imiterere y'ubuso, ubuso bwa fibre ya karuboni buraryoshye kandi bufite amatsinda make y'imikorere. Ibi biterwa nuko mu gihe cyo gutegura fibre ya karuboni, karuboni ikoreshwa mu bushyuhe bwinshi n'ubundi buryo bwo kuyivura bituma ubuso bwa fibre ya karuboni butagira aho buhuriye n'isuku. Ubu buryo buzana imbogamizi nyinshi mu gutegura fibre ya karuboni.
Ubuso bworoshye butuma isano iri hagati ya fibre ya karuboni n'ibikoresho bya matrix igabanuka. Mu gutegura ibivanze, biragoye ko ibikoresho bya matrix bikora isano ikomeye ku buso bwafibre ya karuboni, ibyo bikaba bigira ingaruka ku mikorere rusange y'ibikoresho bivanze. Icya kabiri, kutagira amatsinda mato akora bigabanya uburyo ibinyabutabire bikoreshwa hagati y'imigozi ya karuboni n'ibikoresho bya matrix. Ibi bituma isano iri hagati y'ibi byombi ishingira ahanini ku ngaruka zifatika, nko gushyiramo ibikoresho mu buryo bw'ikoranabuhanga, n'ibindi, akenshi bidahamye bihagije kandi bishobora gutandukana iyo bishyizwemo imbaraga zo hanze.
Imbonerahamwe y'icyitegererezo cy'uburyo imyenda ya fibre ya karuboni ikomeza gukoreshwa n'utubumbe twa nanotubes twa karuboni
Kugira ngo ibyo bibazo bikemuke, ni ngombwa kuvura fibre za karuboni.insinga za karubonikugaragaza impinduka zikomeye mu ngingo nyinshi.
Uburyo bwo gukora butuma imiyoboro ya karuboni ikomera. Binyuze mu kuyungurura imiti, kuvurwa mu maraso n'ubundi buryo, utwobo duto n'imiyoboro bishobora gucukurwa mu buso bw'imiyoboro ya karuboni, bigatuma imiterere yayo iba mibi. Ubu buso bugoye bwongera aho imiyoboro ya karuboni ihurira n'ibikoresho bya substrate, ibyo bigatuma imikorere ya mekanike irushaho kuba myiza. Iyo ibikoresho bya matrix bifatanye na fibre ya karuboni, bibasha kwishyira muri izi nyubako zikomeye, bigatuma habaho imikoranire ikomeye.
Uburyo bwo gukora bushobora kwinjiza amatsinda menshi y’imikorere ahindura imikorere ku buso bwa fibre ya karuboni. Aya matsinda y’imikorere ashobora kwinjiza imikorere mu buryo bwa shimi n’amatsinda y’imikorere ajyanye nayo mu bikoresho bya matrix kugira ngo habeho imigozi ya shimi. Urugero, uburyo bwo kuvura oxidation bushobora kwinjiza amatsinda ya hydroxyl, amatsinda ya karuboni n’andi matsinda y’imikorere ku buso bwa fibre ya karuboni, ashobora kwinjiza imikorere mu buryo bwaepoxyamatsinda muri resin matrix n'ibindi kugira ngo bikore covalent bonds. Ingufu z'iyi chemical bond ziri hejuru cyane kurusha iz'physical bond, ibyo bikaba byongera cyane imbaraga zo guhuza hagati ya fibre ya karuboni n'ibikoresho bya matrix.
Ingufu zo hejuru za fibre ya karuboni ikora nazo ziyongera cyane. Ubwiyongere bw'ingufu zo hejuru butuma fibre ya karuboni itoserwa n'ibikoresho bya matrix, bityo byoroshya gukwirakwira no kwinjira kw'ibikoresho bya matrix ku buso bwa fibre ya karuboni. Mu gutegura ibivanze, ibikoresho bya matrix bishobora gukwirakwizwa neza ku mpande za fibre ya karuboni kugira ngo bikore imiterere ikomeye. Ibi ntibinoza gusa imiterere y'ibikoresho bya matrix, ahubwo binanoza n'indi miterere yabyo, nko kurwanya ingese no kudahungabana k'ubushyuhe.
Imigozi ya karuboni ikora ifite inyungu nyinshi mu gutegura imvange ya karuboni.
Ku bijyanye n'imiterere ya mekanike, imbaraga zo guhuza hagati y'ibikoresho byakozweinsinga za karubonikandi ibikoresho bya matrix birarushaho kunozwa, bigatuma ibyo bikoresho bihuza ibintu bishobora kohereza neza imihangayiko iyo bishyizwe mu mbaraga zo hanze. Ibi bivuze ko imiterere y'ibikoresho nk'imbaraga na modulus irushaho kunozwa cyane. Urugero, mu kibuga cy'indege, gisaba imiterere ikomeye cyane ya mekanike, ibice by'indege bikozwe mu bikoresho bya karubone bishobora kwihanganira imitwaro myinshi yo kuguruka no kunoza umutekano n'ubwizigirwa bw'indege. Mu rwego rw'ibikoresho bya siporo, nk'amafuremu y'amagare, ibyuma bya golf, nibindi, ibikoresho bya karubone bishobora gutanga imbaraga n'ubudahangarwa bwiza, mu gihe bigabanya ibiro kandi bikanoza ubunararibonye bw'abakinnyi.
Ku bijyanye no kurwanya ingese, bitewe no kwinjiza amatsinda y’imikorere akoreshwa ku buso bw’imigozi ya karuboni ikora, aya matsinda y’imikorere ashobora gukora imikoranire ihamye y’ibinyabutabire n’ibikoresho bya matrix, bityo bikanoza ubudahangarwa bw’ingese bw’ibinyabutabire. Mu bihe bimwe na bimwe by’ibidukikije, nko mu bidukikije byo mu mazi, inganda z’ibinyabutabire, n’ibindi, imikorere ikoreshwaibinyabutabire bya fibre ya karubonibishobora kurwanya neza kwangirika kw'ibikoresho byangiza no kongera igihe cyo gukora. Ibi bifite akamaro kanini ku bikoresho bimwe na bimwe n'inyubako bikoreshwa mu bidukikije bibi igihe kirekire.
Ku bijyanye no kudahindagurika kw'ubushyuhe, guhuza neza hagati y'ibinyabutabire bya karubone bikozwe mu buryo bwa "activated carbon fiber" n'ibikoresho bya "matrix" bishobora kunoza uburyo ibinyabutabire bihagaze neza. Mu gihe cy'ubushyuhe bwinshi, ibinyabutabire bishobora kugumana imiterere myiza ya mekanike n'uburyo bitagenda neza, kandi ntibishobora kwangirika cyangwa kwangirika cyane. Ibi bituma ibinyabutabire bya karubone bikozwe mu buryo bwa "activated carbon fiber" bifite amahirwe menshi yo gukoreshwa mu buryo bushyuha cyane, nk'ibice bya moteri y'imodoka n'ibice bishyuha bya moteri y'indege.
Mu bijyanye n'imikorere yo gutunganya, imigozi ya karubone ikora cyane yongera imikorere yo hejuru kandi ihura neza n'ibikoresho bya matrix. Ibi bituma byoroha ko ibikoresho bya matrix byinjira kandi bigakira ku buso bwa fibre ya karubone mu gihe cyo gutegura ibikoresho bivanze, bityo bikanongera imikorere myiza n'ubwiza bw'ibicuruzwa. Muri icyo gihe, imiterere y'ibivanze bya fibre ya karubone ikora nayo irarushaho kwiyongera, bigatuma bihindurwa kugira ngo bikoreshwe mu buryo butandukanye kandi bihuze n'ibikenewe mu buhanga butandukanye.
Bityo rero, uburyo bwo kuvura indwarainsinga za karubonini ingenzi mu gutegura imvange y’ibinyabutabire bya karuboni bitanga umusaruro mwinshi. Binyuze mu kuvura imvange y’ibinyabutabire, imiterere y’ubuso bwa karuboni ishobora kunozwa kugira ngo yongere ubukana bw’ubuso, itangize amatsinda akora, kandi inoze ingufu z’ubuso, kugira ngo hongerwe imbaraga zo guhuza hagati ya karuboni n’ibikoresho bya matrix, kandi hashyirweho urufatiro rwo gutegura imvange y’ibinyabutabire bya karuboni bifite imiterere myiza ya mekanike, birwanya ingese, bihamye mu bushyuhe kandi bigakora neza. Bitewe n’iterambere rihoraho rya siyansi n’ikoranabuhanga, byizewe ko ikoranabuhanga rikoresha karuboni rizakomeza guhanga udushya no gutera imbere, ritanga inkunga ikomeye mu ikoreshwa ryagutse rya karuboni.
