Cov teb thov ntawm cov ntaub ntawv carbon / carbon composite

Txij li thaum nws tsim tawm xyoo 1960,Cov khoom sib xyaw ua ke carbon-carbon C/Ctau txais kev saib xyuas zoo los ntawm cov tub rog, aerospace, thiab nuclear energy industries. Nyob rau theem thaum ntxov, cov txheej txheem tsim khoom ntawmcov pa roj carbon-carbon sib xyaw ua kenyuaj heev, nyuaj rau kev siv tshuab, thiab cov txheej txheem npaj khoom ntev heev. Tus nqi ntawm kev npaj khoom tseem siab ntev heev, thiab nws siv tau txwv rau qee qhov chaw uas muaj kev ua haujlwm hnyav, nrog rau aerospace thiab lwm yam teb uas tsis tuaj yeem hloov los ntawm lwm cov ntaub ntawv. Tam sim no, qhov kev tsom mus rau kev tshawb fawb txog carbon/carbon composite feem ntau yog rau kev npaj pheej yig, tiv thaiv kev oxidation, thiab kev sib txawv ntawm kev ua tau zoo thiab cov qauv. Ntawm lawv, cov thev naus laus zis npaj ntawm cov khoom siv carbon/carbon ua tau zoo thiab pheej yig yog qhov kev tsom mus rau kev tshawb fawb. Cov tshuaj lom neeg vapor deposition yog txoj hauv kev nyiam tshaj plaws rau kev npaj cov khoom siv carbon/carbon ua tau zoo thiab siv dav hauv kev tsim khoom lag luam ntawmCov khoom sib xyaw ua ke C/CTxawm li cas los xij, cov txheej txheem kev siv tshuab siv sijhawm ntev, yog li tus nqi tsim khoom siab. Kev txhim kho cov txheej txheem tsim khoom ntawm cov pa roj carbon / carbon composites thiab kev tsim cov pa roj carbon / carbon composites uas pheej yig, ua haujlwm siab, loj, thiab cov qauv nyuaj yog qhov tseem ceeb rau kev txhawb nqa kev siv cov khoom siv no hauv kev lag luam thiab yog qhov tseem ceeb ntawm kev txhim kho ntawm cov pa roj carbon / carbon composites.

Piv nrog cov khoom siv graphite ib txwm muaj,cov khoom siv sib xyaw ua ke carbon-carbonmuaj cov txiaj ntsig zoo tshaj plaws hauv qab no:

1) Lub zog siab dua, lub neej khoom ntev dua, thiab txo cov lej hloov khoom, yog li ua rau kev siv khoom siv ntau dua thiab txo cov nqi txij nkawm;

2) Kev ua haujlwm thermal qis dua thiab kev ua haujlwm rwb thaiv tsev zoo dua, uas yog qhov zoo rau kev txuag hluav taws xob thiab kev txhim kho kev ua haujlwm zoo;

3) Nws tuaj yeem ua kom nyias dua, yog li cov khoom siv uas twb muaj lawm tuaj yeem siv los tsim cov khoom siv lead ua ib leeg nrog cov kab uas hla loj dua, txuag tus nqi ntawm kev nqis peev rau cov khoom siv tshiab;

4) Kev nyab xeeb siab, tsis yooj yim tawg hauv qab qhov kub siab rov ua dua;

5) Muaj peev xwm tsim tau zoo. Cov ntaub ntawv graphite loj nyuaj rau ua kom zoo nkauj, thaum cov ntaub ntawv sib xyaw ua ke uas muaj carbon ntau tuaj yeem ua tiav qhov zoo nkauj ze-net thiab muaj qhov zoo ntawm kev ua tau zoo hauv kev siv lub tshuab cua sov thermal field loj.

Tam sim no, qhov kev hloov pauv ntawm cov khoom tshwj xeebcov khoom siv graphitexws liisostatic graphitelos ntawm cov khoom siv sib xyaw ua ke uas muaj cov pa roj carbon siab heev yog raws li nram no:

Qhov kub thiab txias zoo heev thiab hnav tsis kam ntawm cov ntaub ntawv carbon-carbon ua rau lawv siv dav hauv kev tsav dav hlau, aerospace, lub zog, tsheb, tshuab thiab lwm yam teb.

Cov ntawv thov tshwj xeeb yog raws li nram no:

1. Kev lag luam dav hlau:Cov ntaub ntawv sib xyaw ua ke carbon-carbon tuaj yeem siv los tsim cov khoom kub siab, xws li lub cav dav hlau nozzles, phab ntsa combustion chamber, cov hniav qhia, thiab lwm yam.

2. Kev lag luam dav hlau:Cov ntaub ntawv sib xyaw ua ke carbon-carbon tuaj yeem siv los tsim cov ntaub ntawv tiv thaiv cua sov rau lub dav hlau, cov ntaub ntawv tsim kho lub dav hlau, thiab lwm yam.

3. Lub zog teb:Cov ntaub ntawv sib xyaw ua ke carbon-carbon tuaj yeem siv los tsim cov khoom siv nuclear reactor, cov khoom siv petrochemical, thiab lwm yam.

4. Kev lag luam tsheb:Cov ntaub ntawv sib xyaw ua ke carbon-carbon tuaj yeem siv los tsim cov tshuab nres, clutches, cov ntaub ntawv sib txhuam, thiab lwm yam.

5. Kev ua haujlwm txhua yam:Cov ntaub ntawv sib xyaw ua ke carbon-carbon tuaj yeem siv los tsim cov bearings, seals, mechanical parts, thiab lwm yam.
