Ni bangahe ubushyuhe bwo hejuru bushobora kwihanganira fibre ya karubone, kuki ibicuruzwa byinshi bya fibre fibre bidashobora kwihanganira ubushyuhe bwinshi

Ukuntu ubushyuhe bwo hejuru bushobora kwihanganira fibre ya karubone
Fibre ya karubone ubwayo ifite ubushyuhe bwo hejuru cyane, kandi birashobora kuvugwa ko ari ibintu birwanya ubushyuhe bukabije cyane, ariko ibikoresho bya karuboni biva mu bikoresho bya matrix.
Yan F cone ikuramo ibikoresho bibisi muri peteroli namakara.Ubwa mbere, polyacrylonitrile ikuramo, hanyuma fibre ya karubone ikurwa muri polyacrylonitrile.Ibisabwa bya tekiniki hano ni hejuru cyane, kandi okiside, karuboni na grafitike mubikorwa byose nibyose Birakeneye ubushyuhe bwo hejuru kugirango birangire, cyane cyane munsi yubushyuhe bwo hejuru bwa dogere ibihumbi byinshi bya kariyeri yamabuye, nyuma yo gukuraho ikinyamakuru, karuboni fibre iboneka, bityo fibre ya karubone ubwayo ifite ubushyuhe bwo hejuru cyane, irashobora kwihanganira ubushyuhe bwo hejuru bwa 3000 ℃, kandi irashobora gukomeza ibyiza byiza.
Kuki ibicuruzwa byinshi bya fibre fibre bidashobora kwihanganira ubushyuhe bwinshi?
Nkuko byavuzwe haruguru, fibre ya karubone ifite ubushyuhe bwiza kandi bwo hejuru.Mu gukora ibicuruzwa bya fibre fibre, ntabwo ari ibikoresho bya fibre fibre.Ibikoresho bya matrix birasabwa kandi kurangiza umusaruro wibicuruzwa bitinze.Ibicuruzwa bya fibre karubone birwanya ubushyuhe bwinshi.Reba ubushyuhe bwo hejuru bwibikoresho fatizo.
Kuba ibicuruzwa byinshi bya fibre fibre bitanyunyuza kandi ngo bishyushye ni ukubera ko ibikoresho bya karuboni fibre yibikoresho ahanini ari fibre fibre + resin ishingiye kubikoresho, kandi ibikubiye muri fibre yatinze gukururwa mubikoresho bigize ni hafi 40% -45%, bityo umusaruro Ubushyuhe bwo hejuru bwibicuruzwa bya karubone byarangiye bifitanye isano nubushyuhe bwo hejuru bwa resin.Ibi ni nkihame ryibiti byimbaho.Umubare ntarengwa wo kurwanya ubushyuhe bwa resin wabaye urugero rwo hejuru rwubushyuhe bwo hejuru bwibicuruzwa bya fibre karubone.
Mubihe bisanzwe, ubushyuhe bwo hejuru bwa matinike ya resin ni 180C.Niba irenze ubu bushyuhe igihe kirekire, bizatera matrike ya resin gushonga, bizagira ingaruka kumikorere yanyuma yibicuruzwa.
Mubyongeyeho, kugirango turusheho kunoza ubushyuhe bwo hejuru, urutoki rwibiti ruzahitamo matrix ifite ubushyuhe bwo hejuru cyane, ni ukuvuga plastiki idasanzwe.Niba ufite matrise ifite ibyiza byo gukora cyane nka PEK na PPS, noneho ibicuruzwa bya fibre fibre yakozwe bizarwanya Ubushyuhe bushobora kugera hejuru ya 20YC.Niba hakenewe kurwanya ubushyuhe bwinshi, materix ya carbone cyangwa ceramic igomba guhitamo.Ubushyuhe bwo hejuru burashobora kuba bwiza.
