Magawo ogwiritsira ntchito zida za carbon/carbon composite

Kuyambira pomwe idapangidwa m'ma 1960, gulu lacarbon-carbon C/C compositesalandira chidwi chachikulu kuchokera ku zankhondo, zamlengalenga, ndi mafakitale amagetsi a nyukiliya. Kumayambiriro koyambirira, njira yopangiracarbon-carbon kompositizinali zovuta, mwaukadaulo zovuta, ndipo njira yokonzekera inali yayitali. Mtengo wokonzekera mankhwala wakhalabe wokwera kwa nthawi yaitali, ndipo ntchito yake yakhala ikugwiritsidwa ntchito kumadera ena omwe ali ndi zovuta zogwirira ntchito, komanso malo opangira ndege ndi madera ena omwe sangathe kusinthidwa ndi zipangizo zina. Pakalipano, cholinga cha kafukufuku wa carbon / carbon composite makamaka pakukonzekera zotsika mtengo, anti-oxidation, ndi mitundu yosiyanasiyana ya machitidwe ndi mapangidwe. Pakati pawo, luso lokonzekera lapamwamba kwambiri komanso lotsika mtengo la carbon / carbon composites ndilo cholinga cha kafukufuku. Chemical vapor deposition ndiyo njira yomwe imakonda kwambiri pokonzekera ma composite apamwamba kwambiri a carbon/carbon ndipo amagwiritsidwa ntchito kwambiri popanga mafakitale.C/C zopangidwa ndi kompositi. Komabe, njira yaukadaulo imatenga nthawi yayitali, kotero kuti mtengo wopangira ndi wokwera. Kupititsa patsogolo njira zopangira zida za kaboni / kaboni ndikupanga zotsika mtengo, zogwira ntchito kwambiri, zazikulu, zazikulu komanso zovuta kupanga zida za kaboni / kaboni ndiye chinsinsi cholimbikitsa kugwiritsa ntchito zinthuzi m'mafakitale ndipo ndiye njira yayikulu yopangira kaboni. / kaboni kompositi.

Poyerekeza ndi zinthu zakale za graphite,zinthu zopangidwa ndi carbon-carbon compositeali ndi zabwino izi:

1) Mphamvu zapamwamba, moyo wautali wazinthu, ndikuchepetsa kuchuluka kwa zida zosinthira, potero kumawonjezera kugwiritsa ntchito zida ndikuchepetsa mtengo wokonza;

2) Kutsika kwamafuta otsika komanso magwiridwe antchito abwino amafuta, omwe amathandizira kupulumutsa mphamvu komanso kukonza bwino;

3) Itha kukhala yocheperako, kotero kuti zida zomwe zilipo zitha kugwiritsidwa ntchito kupanga makristalo amodzi okhala ndi mainchesi akulu, kupulumutsa ndalama zogulira zida zatsopano;

4) Kutetezedwa kwakukulu, kosavuta kung'amba pansi pa mobwerezabwereza kutentha kwa kutentha;

5) Mapangidwe amphamvu. Zida zazikulu za graphite zimakhala zovuta kuumba, pamene zipangizo zamakono zopangira mpweya zimatha kukwaniritsa mawonekedwe apafupi ndi ukonde ndipo zimakhala ndi ubwino wodziwikiratu m'munda wa ng'anjo yotentha yamtundu umodzi wa kristalo.

Pakali pano, m'malo wapaderamankhwala a graphitemongaisostatic graphitendi zida zapamwamba zopangidwa ndi kaboni zophatikizana ndi izi:

Kukaniza kwambiri kutentha kwambiri komanso kukana kuvala kwa zida za carbon-carbon composite zimapangitsa kuti azigwiritsidwa ntchito kwambiri muzamlengalenga, zakuthambo, mphamvu, magalimoto, makina ndi magawo ena.

Mapulogalamu enieni ndi awa:

1. Malo oyendetsa ndege:Zida zophatikizika za kaboni-carbon zitha kugwiritsidwa ntchito kupanga zida zotentha kwambiri, monga ma nozzles a injini ya jet, makoma a chipinda choyaka moto, masamba owongolera, ndi zina zambiri.

2. Malo apamlengalenga:Zida zophatikizika ndi kaboni-carbon zitha kugwiritsidwa ntchito kupanga zida zodzitetezera m'mlengalenga, zida zamapangidwe amlengalenga, ndi zina.

3. Mphamvu yamagetsi:Zida zophatikizika za Carbon-carbon zitha kugwiritsidwa ntchito kupanga zida zanyukiliya, zida za petrochemical, ndi zina.

4. Malo agalimoto:Zida zophatikizika za carbon-carbon zitha kugwiritsidwa ntchito popanga ma braking system, ma clutches, zida zamakangano, ndi zina.

5. Ntchito zamakina:Zida zophatikizika za kaboni-carbon zitha kugwiritsidwa ntchito popanga mayendedwe, zisindikizo, zida zamakina, ndi zina zambiri.
