Gukoresha Fiber ya Karuboni Igufi Cyane

Nk'igice cy'ingenzi mu ishami rigezweho ry'ibinyabutabire, fibre ya karuboni ngufi cyane, ifite imiterere yihariye, yakuruye ibitekerezo byinshi mu nzego nyinshi z'inganda n'ikoranabuhanga. Itanga igisubizo gishya ku mikorere myiza y'ibikoresho, kandi gusobanukirwa neza ikoranabuhanga rikoreshwa n'imikorere yabyo ni ngombwa kugira ngo iterambere ry'inganda zifitanye isano ritere imbere.

Mikorografi za elektroni z'imigozi migufi ya karuboni

Ubusanzwe, uburebure bw'imigozi migufi cyane ya karuboni buri hagati ya mm 0.1 na 5, kandi ubucucike bwabyo buri hasi kuri 1.7 - 2g / cm³. Hamwe n'ubucucike buke bwa 1.7 - 2.2g / cm³, imbaraga zo gukurura za 3000 - 7000MPa n'uburyo bwo gushisha bwa 200 - 700GPa, iyi miterere myiza ya mekanike ni yo ishingiro ryo gukoreshwa mu nyubako zitwara imizigo. Byongeye kandi, ifite ubushobozi bwo kwihanganira ubushyuhe bwinshi, kandi ishobora kwihanganira ubushyuhe bwinshi bwa dogere selisiyusi zirenga 2000 mu kirere kidahumanya.

Ikoranabuhanga mu Gukoresha n'Inzira ya Fibre ya Karuboni Igufi Cyane mu Rwego rw'Indege

Mu rwego rw'ikirere, fibre ya karuboni ngufi cyane ikoreshwa cyane cyane mu gushimangiraresinibigize matrix. Urufunguzo rw'ikoranabuhanga ni ugukora fibre ya karuboni ikwirakwira neza muri matrix ya resin. Urugero, gukoresha ikoranabuhanga ryo gukwirakwiza ikoranabuhanga rya ultrasonic bishobora gusenya neza imiterere ya fibre ya karuboni, ku buryo igipimo cyo gukwirakwiza kigera ku kigero kirenga 90%, bigatuma imiterere y'ibikoresho ihora ihindagurika. Muri icyo gihe, gukoresha ikoranabuhanga ryo gutunganya ubuso bwa fibre, nko gukoreshaumukozi uhuzakuvurwa, bishobora gutumafibre ya karubonikandi imbaraga z'umugozi wo guhuza resin ziyongereyeho 30% - 50%.

Mu gukora amababa y'indege n'ibindi bice by'imiterere, hakoreshwa uburyo bwo gukangura ikigega gishyushye. Mbere na mbere, fibre ya karuboni na resin bivanze n'ibipimo runaka byakozwe muri prepreg, bishyirwa mu kigega gishyushye gishyushye. Hanyuma biravurwa bigakorwa ku bushyuhe bwa 120 - 180°C n'umuvuduko wa 0.5 - 1.5MPa. Ubu buryo bushobora gusohora neza utubumbe tw'umwuka mu bikoresho bivanze kugira ngo harebwe ko ibicuruzwa bifite ubucucike n'imikorere myiza.

Ikoranabuhanga n'uburyo bwo gukoresha fibre ya karuboni ngufi cyane mu nganda z'imodoka

Mu gushyira fibre ya karuboni ngufi cyane ku bice by'imodoka, intego ni ukunoza imikoranire yayo n'ibikoresho by'ibanze. Mu kongeramo ibintu byihariye bihuza, guhuza hagati y'imigozi ya karuboni n'ibikoresho by'ibanze (urugero:polypropylene, n'ibindi) bishobora kwiyongeraho hafi 40%. Muri icyo gihe, kugira ngo kunoze imikorere yayo mu bice bigoye by'imihangayiko, ikoranabuhanga ryo gushushanya icyerekezo cya fibre rikoreshwa mu guhindura icyerekezo cya fibre hakurikijwe icyerekezo cya stress ku gice.

Uburyo bwo gushushanya hakoreshejwe inshinge bukunze gukoreshwa mu gukora ibice nk'udupfundikizo tw'imodoka. Imigozi migufi cyane ya karuboni ivangwa n'uduce twa pulasitiki hanyuma igashyirwa mu mwobo w'ibumba binyuze mu bushyuhe bwinshi n'umuvuduko. Ubushyuhe bwo gushushanya muri rusange ni 200 - 280 ℃, umuvuduko wo gushushanya ni 50 - 150 MPa. Ubu buryo bushobora gutuma ibice bifite ishusho igoye bihinduka vuba, kandi bugatuma imigozi ya karuboni ikwirakwira mu bicuruzwa kimwe.

Ikoranabuhanga n'Inzira yo Gukoresha Fibre ya Karuboni Igufi Cyane mu Rwego rw'Ikoranabuhanga

Mu rwego rwo gukwirakwiza ubushyuhe hakoreshejwe ikoranabuhanga, gukoresha uburyo bwo gutwara ubushyuhe bw'imigozi ya karuboni ikoresha ikoranabuhanga rigezweho ni ingenzi. Mu kunoza urwego rwa graphitization ya fibre ya karuboni, ubushobozi bwayo bwo gutwara ubushyuhe bushobora kwiyongera bukagera ku birenga 1000W / (mK). Hagati aho, kugira ngo ihuze neza n'ibice bya elegitoroniki, ikoranabuhanga ryo gukora metallization ku buso, nko gushyira nickel mu cyuma, rishobora kugabanya ubushobozi bwo guhangana n'imigozi ya karuboni ku kigero kirenga 80%.

Uburyo bwo gucukura ifu bushobora gukoreshwa mu gukora ibikoresho byo gucukura CPU muri mudasobwa. Fibre ya karuboni ivanze n'ifu y'icyuma (urugero: ifu y'umuringa) kandi igacukurwa mu bushyuhe bwinshi n'umuvuduko. Ubushyuhe bwo gucukura muri rusange ni 500 - 900 ° C naho umuvuduko ukaba 20 - 50 MPa. Ubu buryo butuma fibre ya karuboni ikora umuyoboro mwiza wo gucukura ubushyuhe hamwe n'icyuma kandi bukongera ubushobozi bwo gusohora ubushyuhe.

Kuva ku by’indege kugeza ku nganda z’imodoka kugeza ku by’ikoranabuhanga, hamwe n’udushya duhoraho mu ikoranabuhanga no kunoza imikorere, mu buryo bugufi cyane.fibre ya karubonibizamurikira mu nzego nyinshi, bishyiremo imbaraga zikomeye mu bumenyi n'ikoranabuhanga rya none ndetse no mu iterambere ry'inganda.
