Ibikoresho nyamukuru byumuriro wumuriro: C / C ibikoresho

Ibikoresho bya karuboneni ubwoko bwa karuboni fibre igizwe, hamwe na fibre fibre nkibikoresho byongera imbaraga hamwe na karubone yabitswe nkibikoresho bya matrix. Matrix yaC / C igizwe na karubone. Kubera ko hafi ya byose bigizwe na karubone yibanze, ifite ubushyuhe bwo hejuru cyane kandi iragwa imiterere ikomeye ya fibre ya karubone. Yakozwe mu nganda murwego rwo kwirwanaho mbere.

Ahantu ho gusaba:

C / C ibikoreshobiherereye hagati yuruhererekane rwinganda, kandi hejuru yarimo fibre fibre no gukora preform, kandi imirima yo hasi iraguka.C / C ibikoreshozikoreshwa cyane nkibikoresho birwanya ubushyuhe, ibikoresho byo guterana, hamwe nibikoresho bikoreshwa cyane. Zikoreshwa mu kirere (rocket nozzle umuhogo wo mu muhogo, ibikoresho byo gukingira ubushyuhe hamwe na moteri yubushyuhe bwa moteri yubushyuhe), ibikoresho bya feri (gari ya moshi yihuta, disiki ya feri yindege), imirima yumuriro wa fotovoltaque (ingunguru ya insulasiyo, ingenzi, imiyoboro iyobora nibindi bikoresho), umubiri wibinyabuzima (amagufwa yubukorikori) nindi mirima. Kugeza ubu, murugoC / C ibikoreshoibigo byibanda cyane kumurongo umwe wibikoresho bikomatanya kandi bigera kumurongo wo hejuru ugana icyerekezo.

Ibikoresho bya C / C bifite imikorere myiza yuzuye, hamwe nubucucike buke, imbaraga zidasanzwe, modulus yihariye, ubwinshi bwumuriro mwinshi, coefficente yo kwagura ubushyuhe buke, gukomera kuvunika neza, kwihanganira kwambara, kurwanya ablasi, nibindi byumwihariko, bitandukanye nibindi bikoresho, imbaraga z'ibikoresho bya C / C ntibizagabanuka ariko birashobora kwiyongera hamwe no kwiyongera k'ubushyuhe. Nibikoresho byiza birwanya ubushyuhe, bityo rero byakozwe bwa mbere mu nganda mu muhogo wa roketi.

Ibikoresho bya C / C biragwa ibintu byiza byubukanishi hamwe nuburyo bwo gutunganya fibre ya karubone, kandi ifite ubushyuhe bwo kurwanya no kwangirika kwa grafite, kandi yabaye umunywanyi ukomeye wibicuruzwa bya grafite. By'umwihariko mu murima usaba ufite imbaraga nyinshi zisabwa - amashanyarazi yumuriro wa Photovoltaque, ikiguzi-cyiza numutekano wibikoresho bya C / C bigenda bigaragara cyane munsi ya waferi nini ya silicon nini, kandi bimaze kuba icyifuzo gikomeye. Ibinyuranye, grafite yabaye inyongera kubikoresho bya C / C bitewe nubushobozi buke bwo gutanga umusaruro kuruhande.

Amashanyarazi ya Photovoltaque yumuriro:

Umuriro wubushyuhe nuburyo bwose bwo gukomeza imikurire ya silikoni ya monocrystalline cyangwa kubyara silikoni ya polyikristaline mubushyuhe runaka. Ifite uruhare runini mubyera, uburinganire nizindi mico ya silikoni ya monocrystalline na silicon polycrystalline, kandi ni iyimbere yimbere yinganda zikora silikoni. Umuriro wumuriro urashobora kugabanywamo sisitemu yumuriro wa sisitemu ya monocrystalline silicon imwe ya kirisiti ikurura itanura hamwe na sisitemu yumuriro wa polycrystalline itoteri ukurikije ubwoko bwibicuruzwa. Kuva selile ya monocrystalline silicon ifite imikorere ihindagurika kuruta selile silicon polycrystalline, umugabane wamasoko ya waferi ya silikoni ya monocrystalline ukomeje kwiyongera, mugihe umugabane wamasoko ya waferi ya silikoni ya silicon mu gihugu cyanjye wagabanutse uko umwaka utashye, kuva kuri 32.5% muri 2019 ukagera kuri 9.3% muri 2020. Kubwibyo, abakora amashanyarazi yumuriro bakoresha cyane cyane inzira yumuriro wa tekinoroji yumuriro wa kirisiti imwe ikurura itanura.

Igishushanyo 2: Umuriro wubushyuhe murwego rwo gukora inganda za silicon

Umuriro wubushyuhe ugizwe nibice birenga icumi, kandi ibice bine byingenzi nibyingenzi, umuyoboro uyobora, silinderi ya insulation, hamwe nubushyuhe. Ibice bitandukanye bifite ibisabwa bitandukanye kubintu bifatika. Igishushanyo gikurikira nigishushanyo mbonera cyumuriro wumuriro wa kirisiti imwe ya kirisiti. Ikibumbano, umuyoboro uyobora, hamwe na silinderi ya insulasiyo ni ibice byubaka sisitemu yumuriro. Igikorwa cabo nyamukuru nugushyigikira ubushyuhe bwo hejuru bwubushyuhe bwo hejuru, kandi bafite ibisabwa byinshi mubucucike, imbaraga, hamwe nubushyuhe bwumuriro. Ubushyuhe nikintu gishyushya kiziguye mumashanyarazi. Igikorwa cyayo ni ugutanga ingufu zumuriro. Mubisanzwe birwanya, kubwibyo bifite ibisabwa byinshi kugirango birwanye ibintu.
