Gukoresha Ultra-Bigufi ya Carbone Fibre

Nkumunyamuryango wingenzi wumurima wateye imbere, fibre-karbone fibre, hamwe nimiterere yihariye, yatumye abantu benshi bamenyekana mubikorwa byinshi byinganda nubuhanga. Itanga igisubizo gishya kubikorwa byo hejuru byibikoresho, kandi gusobanukirwa byimbitse ikoreshwa ryikoranabuhanga hamwe nibikorwa birakenewe kugirango iterambere ryinganda zifitanye isano.

Mubisanzwe, uburebure bwa fibre ultra-ngufi ya karubone iri hagati ya 0.1 - 5mm, n'ubucucike bwayo buri munsi ya 1.7 - 2g / cm³. Hamwe n'ubucucike buke bwa 1.7 - 2.2g / cm³, imbaraga zingana zingana na 3000 - 7000MPa hamwe na modulus ya elastique ya 200 - 700GPa, iyi mikorere myiza yubukorikori niyo shingiro ryokoreshwa mubikorwa byubaka imitwaro. Byongeye kandi, ifite ubushyuhe buhebuje bwo kurwanya ubushyuhe, kandi irashobora kwihanganira ubushyuhe bwo hejuru ya 2000 ° C mu kirere kitarimo okiside.

Porogaramu Ikoranabuhanga hamwe na Ultra-ngufi ya Carbone Fibre mu kirere

Mu kirere cyo mu kirere, fibre ya ultra-ngufi ya karubone ikoreshwa cyane cyane mu gushimangiraresinmatrix. Urufunguzo rwikoranabuhanga ni ugukora fibre ya karubone ikwirakwira muri matrise. Kurugero, gukoresha tekinoroji ya ultrasonic ikwirakwiza birashobora guca neza ibintu bya karuboni fibre agglomeration, kuburyo coefficient de dispersion igera kuri 90%, ikemeza ko ibintu bifatika. Mugihe kimwe, ikoreshwa rya tekinoroji yo kuvura fibre, nko gukoreshaumukozikuvura, birashobora gukorafibrena resin interineti ihuza imbaraga ziyongereyeho 30% - 50%.

Mugukora amababa yindege nibindi bikoresho byubaka, ikoreshwa ryikigega gishyushye. Mbere ya byose, ultra-ngufi ya karubone fibre na resin bivanze nigice runaka gikozwe muri prereg, gishyirwa mubigega bishyushye. Ihita ikira kandi ikabumbabumbwa ku bushyuhe bwa 120 - 180 ° C n'umuvuduko wa 0.5 - 1.5MPa. Iyi nzira irashobora gusohora neza ibyuka bihumeka mubikoresho byinshi kugirango habeho ubucucike nibikorwa byinshi byibicuruzwa.

Ikoranabuhanga hamwe nuburyo bwo gukoresha Ultra-Bigufi ya Carbone Fibre mu nganda zitwara ibinyabiziga

Iyo ukoresheje ultra-ngufi ya karubone fibre kubice byimodoka, icyibandwaho nukuzamura imikoranire yayo nibikoresho fatizo. Mugushyiramo ibintu byihariye bihuza, guhuza intera hagati ya fibre karubone nibikoresho fatizo (urugeropolipropilene, n'ibindi) birashobora kwiyongera hafi 40%. Muri icyo gihe, kugirango tunoze imikorere yacyo mubibazo bigoye, tekinoroji ya fibre yerekanwe ikoreshwa muguhindura icyerekezo cyo guhuza fibre ukurikije icyerekezo cyo guhangayika kuruhande.

Uburyo bwo guterwa inshinge bukoreshwa kenshi mugukora ibice nka moteri yimodoka. Ultra-ngufi ya fibre fibre ivangwa nuduce twa plastike hanyuma igaterwa mu cyuho kibumbwe binyuze mu bushyuhe bwinshi n’umuvuduko. Ubushyuhe bwo gutera inshinge muri rusange 200 - 280 ℃, igitutu cyo gutera ni 50 - 150 MPa. Ubu buryo burashobora gutahura uburyo bwihuse bwibice bigoye, kandi birashobora gukwirakwiza gukwirakwiza fibre ya karubone mubicuruzwa.

Ikoranabuhanga hamwe na Ultra-ngufi ya Carbone Fibre Porogaramu muri Electronics Field

Mu rwego rwo gukwirakwiza ubushyuhe bwa elegitoronike, gukoresha imashanyarazi yumuriro wa fibre ultra-ngufi ya karubone ni urufunguzo. Mugutezimbere igishushanyo mbonera cya fibre karubone, ubushyuhe bwayo bwumuriro burashobora kwiyongera kugera kuri 1000W / (mK). Hagati aho, kugirango hamenyekane neza imikoreshereze y’ibikoresho bya elegitoronike, tekinoroji y’ubutaka, nka plaque ya nikel, irashobora kugabanya ubukana bwa fibre karubone hejuru ya 80%.

CPU

Powder metallurgie inzira irashobora gukoreshwa mugukora mudasobwa ya CPU. Ultra-ngufi ya karubone ivanze nifu yicyuma (urugero ifu yumuringa) hanyuma ikayungurura ubushyuhe bwinshi nigitutu. Ubushyuhe bwo gucumura muri rusange ni 500 - 900 ° C naho umuvuduko ni 20 - 50 MPa. Ubu buryo butuma fibre ya karubone ikora umuyoboro mwiza wo gutwara ubushyuhe hamwe nicyuma kandi igateza imbere ubushyuhe.

Kuva mu kirere kugera mu nganda zitwara ibinyabiziga kugeza kuri elegitoroniki, hamwe no guhanga udushya mu ikoranabuhanga no gutezimbere inzira, ultra-bigufifibreizamurika mubice byinshi, itera imbaraga zikomeye mubumenyi nubuhanga bugezweho no guteza imbere inganda.
