Imashini ya fibre fibreni Birenzeho-Imperaimashiniibicuruzwa byuruhererekane rwimashini zogosha.Ugereranije nibikoresho gakondo byo kuboha nkurudodo rwipamba hamwe nicyuma, imashini ya karuboni fibre ikenera tekinoroji kandi ikenewe cyane muburyo bwo gukora no gukora.
Ariko, ntawahakana ko ugereranije nibikoresho gakondo, kuboha fibre karubone bifite ibintu byiza cyane, kandi ibyifuzo byayo bizaza ni binini.Iyi ni imwe mu mpamvu zituma ikoranabuhanga rya Benfa ryagiye rihindura ikoranabuhanga rya karuboni fibre icyerekezo cyingenzi.
Ugereranije nibikoresho gakondo bikozwe, ni ibihe bintu biranga ibikoresho bya fibre fibre?
1. Imbaraga zikomeye
Imbaraga zingana za fibre ya karubone igera kuri 2 kugeza kuri 7 GPa, naho modulus ya tensile igera kuri 200 kugeza 700 GPa.Ubucucike buri hagati ya garama 1.5 na 2.0 kuri santimetero kibe, bigenwa ahanini nubushyuhe bwibikorwa bya karubone hiyongereyeho imiterere yubudodo bwumwimerere.Mubisanzwe nyuma yubushyuhe bwo hejuru 3000 treatment kuvura ibishushanyo, ubucucike bushobora kugera kuri garama 2.0 kuri santimetero kibe.Byongeye kandi, uburemere bwacyo bworoshye cyane, uburemere bwacyo bworoshye kuruta aluminium, munsi ya 1/4 cyibyuma, kandi imbaraga zayo zikubye inshuro 20 icyuma.Coefficient yo kwagura ubushyuhe bwa fibre ya karubone itandukanye nizindi fibre, kandi ifite ibiranga anisotropy.
2. Coefficient ntoya yo kwagura ubushyuhe
Coefficient yo kwagura ubushyuhe bwa fibre ya karubone ubwayo ni mbi mu nzu (-0.5 ~ -1.6) × 10-6 / K, ni zeru kuri 200-400 and, na 1.5 × 10-6 / K iyo iri munsi ya 1000 ℃ .Ibikoresho byose bikozwe muri byo bifite coeffisiyoneri yo kwaguka ihamye kandi irashobora gukoreshwa nkigikoresho gisanzwe gipima.
3. Amashanyarazi meza
Mubisanzwe, ubushyuhe bwumuriro bwibikoresho kama nimborera ni bibi, ariko ubushyuhe bwumuriro wa fibre karubone yegereye ibyuma.Kwifashisha iyi nyungu, irashobora gukoreshwa nkibikoresho byo gukusanya izuba hamwe nibikoresho bikoresha ubushyuhe hamwe no guhererekanya ubushyuhe bumwe.
4. Byoroshye kandi bitunganijwe
Usibye ibiranga ibikoresho rusange bya karubone, imyenda ya karubone fibre iboheye ifite ubworoherane bwa anisotropique igaragara kandi irashobora gutunganyirizwa mumyenda itandukanye.Kubera uburemere buke bwihariye, bagaragaza imbaraga nyinshi kuruhande rwa fibre.Carbone fibre ishimangirwa impeta ya Oxygene resin yibikoresho bifite ibipimo byuzuye byerekana imbaraga zihariye hamwe na modulus yihariye mubikoresho byubatswe bihari.
5. Kurwanya ubushyuhe buke
Fibre ya karubone ifite ubushyuhe buke buke, nko kutavunika munsi yubushyuhe bwa azote.
6. Kurwanya ruswa
Fibre ya karubone ifite imbaraga zo kurwanya ruswa yumuti rusange, acide, na alkalis.Ntishobora gushonga cyangwa kubyimba.Ifite imbaraga zo kurwanya ruswa kandi ntabwo ifite ikibazo cy ingese.
7. Kurwanya kwambara neza
Fibre ya karubone nicyuma ntibikunze kwambarwa iyo bisunikanye.Fibre ya karubone ikoreshwa mu gusimbuza asibesitosi mu gukora ibikoresho byo mu rwego rwo hejuru byo guterana, byakoreshejwe nk'ibikoresho bya feri y'indege n'imodoka.
8. Kurwanya ubushyuhe bwiza
Imikorere ya fibre ya karubone ihagaze neza munsi ya 400 ° C, kandi nta mpinduka nini haba no kuri 1000 ° C.Ubushyuhe bwo hejuru burwanya ibikoresho byinshi biterwa ahanini nubushyuhe bwa matrix.Kurwanya ubushyuhe bwigihe kirekire bwibikoresho bishingiye kuri resin bigera kuri 300 only gusa, kandi ubushyuhe bwo hejuru bwubushyuhe bwibikoresho bishingiye kuri ceramic, bishingiye kuri karubone hamwe nibyuma bishingiye ku byuma bishobora guhuza fibre ubwayo.Ibikoresho bya karubone bikoreshwa cyane mu nganda zo mu kirere nkibikoresho birwanya ubushyuhe bwinshi.
9. Ubwiza buhebuje
Fibre ya karubone ifite ubwiza buhebuje (kimwe mubigaragaza ubwiza ni umubare wa garama ya metero 9000 z'uburebure bwa fibre), muri rusange garama 19 gusa, n'imbaraga zingana na kg 300 kuri micron.Nibindi bikoresho bifite ibintu byiza cyane nka fibre karubone.
10. Kurwanya ingaruka mbi kandi byoroshye kwangirika
Oxidation ibaho munsi ya acide ikomeye, imbaraga za electromotive ya fibre karubone ni nziza, kandi ingufu za electromotive ya aluminium alloy ni mbi.Mugihe ibikoresho bya karuboni fibre ikoreshwa hamwe na aluminiyumu, karubone yicyuma, karburizasi hamwe na ruswa yamashanyarazi.Kubwibyo, karuboni fibre igomba gutunganywa mbere yo kuyikoresha.
