Daim ntawv thov teb ntawm carbon / carbon composite cov ntaub ntawv

Txij li thaum nws invention nyob rau hauv 1960s, lubcarbon-carbon C / C compositestau txais kev saib xyuas zoo los ntawm cov tub rog, aerospace, thiab nuclear zog kev lag luam. Nyob rau hauv thaum ntxov theem, kev tsim khoom ntawmcarbon-carbon sib xyawyog complex, technically nyuaj, thiab cov txheej txheem npaj tau ntev. Tus nqi ntawm cov khoom npaj tau nyob twj ywm siab rau lub sijhawm ntev, thiab nws txoj kev siv tau txwv rau qee qhov chaw nrog kev ua haujlwm hnyav, nrog rau aerospace thiab lwm qhov chaw uas tsis tuaj yeem hloov los ntawm lwm cov ntaub ntawv. Tam sim no, lub hom phiaj ntawm kev tshawb fawb ntawm carbon / carbon composite yog feem ntau ntawm cov nqi qis, kev tiv thaiv oxidation, thiab kev sib txawv ntawm kev ua tau zoo thiab cov qauv. Ntawm lawv, kev npaj thev naus laus zis ntawm kev ua haujlwm siab thiab tus nqi qis carbon / carbon composites yog tsom rau kev tshawb fawb. Tshuaj vapor deposition yog txoj kev nyiam rau kev npaj cov pa roj carbon / carbon sib xyaw ua haujlwm siab thiab tau siv dav hauv kev tsim khoom ntawmC / C cov khoom sib xyaw. Txawm li cas los xij, cov txheej txheem kev siv sijhawm ntev, yog li tus nqi tsim khoom yog siab. Txhim kho cov txheej txheem tsim cov pa roj carbon / carbon composites thiab tsim cov nqi qis, ua haujlwm siab, loj-loj, thiab cov txheej txheem carbon / carbon composites yog tus yuam sij rau kev txhawb nqa kev lag luam ntawm cov khoom siv no thiab yog cov qauv kev loj hlob ntawm cov pa roj carbon monoxide. / carbon sib xyaw.

Piv nrog cov khoom siv graphite tsoos,carbon-carbon composite cov ntaub ntawvmuaj qhov zoo tshaj plaws hauv qab no:

1) Lub zog siab dua, cov khoom siv lub neej ntev dua, thiab txo qis ntawm cov khoom siv hloov pauv, yog li nce kev siv cov khoom siv thiab txo cov nqi tu;

2) Tsawg thermal conductivity thiab zoo thermal rwb thaiv tsev kev ua tau zoo, uas yog conducive rau lub zog txuag thiab efficiency txhim kho;

3) Nws tuaj yeem ua thinner, 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 loj dua, txuag tus nqi ntawm kev nqis peev hauv cov khoom siv tshiab;

4) Kev nyab xeeb siab, tsis yooj yim rau tawg nyob rau hauv rov qab kub thermal shock;

5) Muaj zog tsim qauv. Cov ntaub ntawv loj graphite tsis yooj yim rau cov duab, thaum cov ntaub ntawv carbon-raws li cov ntaub ntawv sib xyaw tuaj yeem ua tiav nyob ze-net shaping thiab muaj qhov ua tau zoo ntawm kev ua tau zoo hauv thaj tsam ntawm qhov loj-inch ib leeg siv lead ua cua sov thermal field systems.

Tam sim no, hloov qhov tshwj xeebgraphite khoomxws liisostatic graphitelos ntawm advanced carbon-based composite cov ntaub ntawv yog raws li nram no:

Qhov zoo tshaj plaws kub tsis kam thiab hnav tsis kam ntawm carbon-carbon composite cov ntaub ntawv ua rau lawv lug siv nyob rau hauv aviation, aerospace, lub zog, tsheb, machinery thiab lwm yam teb.

Cov ntawv thov tshwj xeeb yog raws li hauv qab no:

1. Aviation teb:Carbon-carbon composite cov ntaub ntawv tuaj yeem siv los tsim cov khoom kub, xws li lub cav dav hlau nozzles, combustion chamber phab ntsa, phau ntawv qhia, thiab lwm yam.

2. Aerospace teb:Carbon-carbon composite cov ntaub ntawv tuaj yeem siv los tsim cov khoom siv hluav taws xob tiv thaiv hluav taws xob, cov khoom siv hauv lub dav hlau, thiab lwm yam.

3. Lub zog teb:Carbon-carbon composite cov ntaub ntawv tuaj yeem siv los tsim cov khoom siv hluav taws xob nuclear, cov khoom siv petrochemical, thiab lwm yam.

4. Tsheb teb:Cov khoom siv carbon-carbon composite tuaj yeem siv los tsim cov tshuab braking, clutches, cov ntaub ntawv sib txhuam, thiab lwm yam.

5. Mechanical teb:Carbon-carbon composite cov ntaub ntawv tuaj yeem siv los tsim cov bearings, seals, mechanical parts, thiab lwm yam.
