Gutegura inzira ya karubone fibre yibikoresho

Incamake ya Carbone-Carbone Ibikoresho

Carbone / karubone (C / C) ibikoreshoni fibre ya karubone ishimangira ibintu byinshi hamwe nuruhererekane rwibintu byiza cyane nkimbaraga nyinshi na modulus, uburemere bwihariye bwumucyo, coefficient ntoya yo kwagura amashyanyarazi, kurwanya ruswa, kurwanya ubushyuhe bwumuriro, kurwanya ubukana bwiza, hamwe n’imiti ihamye. Nubwoko bushya bwubushyuhe bwo hejuru cyane.

C / C ibikoreshoni ibikoresho byiza byubushyuhe-bukora ibikoresho byububiko. Kimwe nibindi bikoresho-bihanitse cyane, nibikoresho byubatswe bigizwe na fibre-fonction fase nicyiciro cyibanze. Itandukaniro nuko icyiciro cyashimangiwe nicyiciro cyibanze kigizwe na karubone nziza ifite ibintu byihariye.

Ibikoresho bya karubonebigizwe ahanini na karubone, imyenda ya karubone, fibre ya karubone nkibishimangira, hamwe numwuka wabitswe na karubone nka matrix, ariko ifite ikintu kimwe gusa, aricyo karubone. Kugirango twongere ubwinshi, karubone iterwa na karubone yatewe na karubone cyangwa yatewe na resin (cyangwa asfalt), ni ukuvuga ibikoresho bya karubone / karubone bikozwe mubikoresho bitatu bya karubone.

Ibikorwa byo gukora ibikoresho bya karubone-karubone

1) Guhitamo fibre fibre

Guhitamo karuboni fibre bundles hamwe nuburyo bwimiterere yimyenda ya fibre niyo shingiro ryingandaC / C.. Imiterere yubukanishi hamwe nubushuhe bwa C / C birashobora kugenwa muguhitamo neza ubwoko bwa fibre hamwe nibipimo byo kuboha imyenda, nkicyerekezo cyogutondekanya imigozi, icyerekezo cyumutwe, ingano yububiko, nibindi byinshi.

2) Gutegura karubone fibre preform

Carbone fibre preform bivuga icyuho gikozwe muburyo bukenewe bwa fibre ukurikije imiterere yibicuruzwa nibisabwa kugirango ubashe gukora inzira. Hariho uburyo butatu bwingenzi bwo gutunganya ibice byubatswe byateguwe: kuboha byoroshye, kuboha bikomeye no kuboha no kuvanga byoroshye. Inzira nyamukuru yo kuboha ni: kuboha imyenda yumye, gutondekanya mbere yitsinda ryitsinda ryitsinda, gutobora neza kuboha, fibre fibre hamwe nuburinganire butatu-buringaniye bwo kuboha muri rusange. Kugeza ubu, inzira nyamukuru yo kuboha ikoreshwa muri C igizwe nibikoresho bitatu-murwego rusange muri rusange. Mugihe cyo kuboha, fibre zose ziboheye zitunganijwe muburyo runaka. Buri fibre irekuwe kumurongo runaka ugana icyerekezo cyayo kandi igahuzwa hamwe kugirango ikore umwenda. Ikiranga ni uko ishobora gukora ibice bitatu-byinshi-byerekanwe muri rusange, bishobora kugenzura neza ingano ya fibre muri buri cyerekezo cyibikoresho bya C / C, kugirango ibikoresho bya C / C bibashe gukoresha ibikoresho byubukanishi bifatika. mu byerekezo byose.

3) C / C inzira yo gukwirakwiza

Impamyabumenyi nuburyo bwiza bwo kwangirika bigira ingaruka cyane cyane kumiterere yimyenda hamwe nibikorwa byibanze. Uburyo bukoreshwa muri iki gihe burimo karubonike yatewe, kwinjiza imyuka ya chimique (CVD), kwinjiza imyuka ya chimique (CVI), gushiramo amazi ya chimique, pyrolysis nubundi buryo. Hariho ubwoko bubiri bwingenzi bwuburyo bukoreshwa: uburyo bwo kwinjiza karubone hamwe nuburyo bwo kwinjiza imyuka ya chimique.

Icyiciro cyamazi impregnation-karubone

Uburyo bwo gutembera kwamazi yoroheje biroroshye mubikoresho kandi bifite akamaro kanini, ubwo rero uburyo bwo kwinjiza ibyiciro byamazi nuburyo bwingenzi bwo gutegura ibikoresho bya C / C. Nukwinjiza preform ikozwe muri fibre ya karubone mumazi utwite, hanyuma bigatuma uwatwite yinjira rwose mubusa bwa preform akoresheje igitutu, hanyuma akanyura murukurikirane rwibikorwa nko gukiza, karubone, no gushushanya, amaherezo akabonaC / C ibikoresho. Ikibi cyayo nuko bisaba inshuro nyinshi gutera inda hamwe na karubone kugirango ugere kubisabwa. Ibigize n'imiterere yibiterwa muburyo bwamazi yo gutera akabariro ni ngombwa cyane. Ntabwo bigira ingaruka gusa kumikorere yubucucike, ahubwo bigira ingaruka kumikorere nubukorikori bwibicuruzwa. Kunoza umusaruro wa karubone yumusemburo no kugabanya ubukonje bwabatwite buri gihe cyabaye kimwe mubibazo byingenzi bigomba gukemurwa mugutegura ibikoresho bya C / C hakoreshejwe uburyo bwo gutera akabariro. Ubukonje bwinshi hamwe n’umusaruro muke wa karubone utwite ni imwe mu mpamvu zingenzi zituma igiciro kinini cyibikoresho bya C / C. Kunoza imikorere yibitwite ntibishobora gusa kunoza umusaruro wibikoresho bya C / C hamwe no kugabanya ibiciro byabyo, ariko kandi binatezimbere imitungo itandukanye yibikoresho bya C / C. Kurwanya anti-okiside ivura C / C ibikoresho bya fibre Carbone itangira okiside kuri 360 ° C mukirere. Graphite fibre iruta gato fibre ya karubone, kandi ubushyuhe bwayo bwa okiside itangira okiside kuri 420 ° C. Ubushyuhe bwa okiside bwibikoresho bya C / C bigera kuri 450 ° C. Ibikoresho bya C / C biroroshye cyane okiside mu kirere cyo hejuru cya oxydeide, kandi igipimo cya okiside cyiyongera vuba hamwe no kwiyongera kwubushyuhe. Niba nta ngamba zo kurwanya okiside, gukoresha igihe kirekire ibikoresho bya C / C bikomatanyije mubushyuhe bwo hejuru bwa oxydeide byanze bikunze bizatera ingaruka mbi. Kubwibyo, imiti igabanya ubukana bwa C / C yibikoresho byahindutse igice cyingenzi mubikorwa byayo. Urebye tekinoroji yo kurwanya okiside, irashobora kugabanywamo tekinoroji yo kurwanya anti-okiside imbere hamwe na tekinoroji yo kurwanya anti-okiside.

Icyuka cya Shimi Icyiciro

Imyuka ya chimique (CVD cyangwa CVI) nugushira karubone mu byobo byubusa kugirango ugere ku ntego yo kuzuza imyenge no kongera ubucucike. Carbone yabitswe iroroshye gushushanya, kandi ifite umubiri mwiza uhuza fibre. Ntabwo izagabanuka mugihe cyo kongera karubone nkuburyo bwo gutera akabariro, kandi imiterere yumubiri nubukanishi bwubu buryo nibyiza. Ariko, mugihe cya CVD, niba karubone ishyizwe hejuru yubusa, bizarinda gaze gukwirakwira mumyenge yimbere. Carbone yashyizwe hejuru igomba gukurwaho muburyo bwa mashini hanyuma hagakorwa uruziga rushya. Kubicuruzwa bibyibushye, uburyo bwa CVD nabwo bufite ingorane zimwe, kandi inzinguzingo yubu buryo nayo ni ndende cyane.
