Iinkalo zesicelo se-carbon / carbon composite materials

Ukususela ekuyilweni kwayo ngeminyaka yee-1960, icarbon-carbon C / C imidibanisobaye bafumana ingqwalasela enkulu evela emkhosini, i-aerospace, kunye nemizi-mveliso yamandla enyukliya. Kwinqanaba lokuqala, inkqubo yokuvelisai-carbon-carbon compositeyayintsonkothile, inzima ngokobugcisa, kwaye inkqubo yokulungiselela yayinde. Iindleko zokulungiswa kwemveliso ziye zahlala ziphakamileyo ixesha elide, kwaye ukusetyenziswa kwayo kunqunyelwe kwiindawo ezithile ezineemeko ezinzima zokusebenza, kunye ne-aerospace kunye nezinye iindawo ezingenakuthatyathelwa indawo zezinye izinto. Okwangoku, ugxininiso lwekhabhoni / uphando oludibeneyo lwekhabhoni lujolise kakhulu ekulungiseleleni ixabiso eliphantsi, i-anti-oxidation, kunye ne-diversification yokusebenza kunye nesakhiwo. Phakathi kwazo, iteknoloji yokulungiselela i-high-performance kunye nexabiso eliphantsi lekhabhoni / i-carbon composites yinjongo yophando. Ukubekwa komphunga kwikhemikhali yindlela ekhethwayo yokulungisa imidibaniso yekhabhoni/yekhabhoni esebenza kakhulu kwaye isetyenziswa ngokubanzi kwimveliso yemizi-mveliso.Iimveliso ezihlanganisiweyo zeC/C. Nangona kunjalo, inkqubo yobugcisa ithatha ixesha elide, ngoko ke ixabiso lemveliso liphezulu. Ukuphucula inkqubo yokuvelisa i-carbon / carbon composites kunye nokuphuhlisa ixabiso eliphantsi, ukusebenza okuphezulu, ubungakanani obukhulu, kunye ne-composite ye-carbon / carbon composite iyisitshixo ekukhuthazeni ukusetyenziswa kwemizi-mveliso yale nto kwaye iyona nto iphambili yophuhliso lwekhabhoni. /ikhompositi zekhabhoni.

Xa kuthelekiswa neemveliso zegraphite zemveli,izinto ezidityanisiweyo zekhabhon-carbonziluncedo zilandelayo:

I-1) Amandla aphezulu, ubomi obude bemveliso, kunye nenani elincitshisiweyo lokutshintshwa kwecandelo, ngaloo ndlela ukwandisa ukusetyenziswa kwezixhobo kunye nokunciphisa iindleko zokugcina;

2) I-conductivity ephantsi ye-thermal kunye nokusebenza okungcono kwe-thermal insulation, ehambelana nokugcinwa kwamandla kunye nokuphucula ukusebenza kakuhle;

I-3) Inokuthi yenziwe ibe yincinci, ukwenzela ukuba izixhobo ezikhoyo zingasetyenziselwa ukuvelisa iimveliso ze-crystal enye kunye nobubanzi obukhulu, ukugcina iindleko zotyalo-mali kwizixhobo ezitsha;

4) Ukhuseleko oluphezulu, akulula ukuqhekeza phantsi kokuphindaphindiweyo kwiqondo lokushisa eliphezulu lokutshatyalaliswa kwe-thermal;

5) Uyilo oluqinileyo. Izinto ezinkulu zegraphite zinzima ukumila, ngelixa izinto eziphambili ze-carbon-based composite zinokufikelela ekubunjweni kwe-net-net kwaye zibe neenzuzo ezicacileyo zokusebenza kwintsimi ye-dimeter enkulu ye-crystal eyodwa ye-furnace field systems.

Okwangoku, ukutshintshwa kwezinto ezizodwaiimveliso zegraphitenjengeigraphite ye-isostaticngezinto ezidityanisiweyo ezisekwe kwikhabhoni zimi ngolu hlobo lulandelayo:

Ukumelana nobushushu obuphezulu kunye nokunganyangeki kokunxiba kwekhabhon-carbon-composite materials kubenza basetyenziswe ngokubanzi kwinqwelomoya, kwi-aerospace, amandla, iimoto, oomatshini kunye namanye amacandelo.

Izicelo ezikhethekileyo zezi zilandelayo:

1. Indawo yezophapho:Izinto ezixutywe nekhabhoni-khabhoni zingasetyenziselwa ukwenza iindawo ezinobushushu obuphezulu, njengemibhobho yejethi ye-injini, iindonga zegumbi lokutsha, iincakuba zesikhokelo, njl.

2. Indawo ye-Aerospace:Iimathiriyeli zekhabhoni-khabhoni edityanisiweyo zingasetyenziselwa ukwenza izixhobo zokukhusela ubushushu bomkhathi, izixhobo ze-spacecraft zolwakhiwo, njl.

3. Indawo yamandla:Imathiriyeli edityanisiweyo yeCarbon-carbon ingasetyenziselwa ukwenza amacandelo ereactor yenyukliya, izixhobo zepetrochemical, njl.

4. Indawo yemoto:Izixhobo zekhabhon-carbon composite zingasetyenziselwa ukwenza iinkqubo zokuqhobosha, ii-clutches, izinto zokukhuhlana, njl.

5. Indawo yoomatshini:Izixhobo zekhabhon-carbon composite ingasetyenziselwa ukwenza iibheringi, izitywina, iinxalenye zoomatshini, njl.
