Akụkụ ngwa nke ihe mejupụtara carbon/carbon

Kemgbe e mepụtara ya na 1960, ndịihe mejupụtara carbon-carbon C/Cenwetawo nlebara anya dị ukwuu site n'aka ndị agha, ikuku ikuku, na ụlọ ọrụ ike nuklia. Na mmalite ogbo, n'ichepụta usoro nkecarbon-carbon mejupụtaradị mgbagwoju anya, teknụzụ siri ike, na usoro nkwadebe dị ogologo. Ọnụ ego nke nkwadebe ngwaahịa ka dị elu ruo ogologo oge, a na-eji ya eme ihe na akụkụ ụfọdụ nwere ọnọdụ ọrụ siri ike, yana ikuku na mpaghara ndị ọzọ na-enweghị ike iji ihe ndị ọzọ dochie ya. Ka ọ dị ugbu a, nleba anya nke nyocha ihe mejupụtara carbon/carbon bụ ọkachasị na nkwadebe dị ọnụ ala, mgbochi oxidation, na mgbanwe dị iche iche nke arụmọrụ na nhazi. N'ime ha, nkà na ụzụ nkwadebe nke ihe ndị na-arụ ọrụ dị elu na ọnụ ala carbon / carbon composites bụ ihe nyocha nke nyocha. Kemịkalụ vapor deposition bụ usoro ahọrọ maka ịkwadebe ihe mejupụtara carbon/carbon na-arụ ọrụ dị elu ma jiri ya mee ihe na mmepụta nke ụlọ ọrụ mmepụta ihe.Ngwaahịa mejupụtara C/C. Otú ọ dị, usoro nkà na ụzụ na-ewe ogologo oge, ya mere ọnụ ahịa mmepụta dị elu. Ịkwalite usoro mmepụta nke carbon / carbon composites na ịmepụta ọnụ ala dị ala, arụmọrụ dị elu, nnukwu nha, na ihe mgbagwoju anya nke carbon / carbon composites bụ isi ihe na-akwalite ngwa mmepụta ihe nke ihe a na bụ isi mmepe mmepe nke carbon. / carbon composites.

1) Ike dị elu, ogologo ndụ ngwaahịa, na ọnụ ọgụgụ nke ihe ngbanwe nke akụrụngwa na-ebelata, si otú ahụ na-abawanye ntinye akụrụngwa na ibelata ụgwọ ọrụ;

2) Lower thermal conductivity na arụmọrụ mkpuchi ọkụ ka mma, nke na-enyere aka ịchekwa ike na nkwalite arụmọrụ;

3) Enwere ike ime ka ọ dị ntakịrị, nke mere na a pụrụ iji ngwá ọrụ ndị dị ugbu a na-emepụta otu ngwaahịa kristal na nnukwu diameters, na-echekwa ego nke itinye ego na ngwá ọrụ ọhụrụ;

4) Nchekwa dị elu, ọ dịghị mfe ịgbawa n'okpuru ujo okpomọkụ dị elu ugboro ugboro;

5) ike designability. Nnukwu graphite ihe na-esi ike ịkpụzi, ebe elu carbon dabeere mejupụtara ihe nwere ike nweta nso-net nhazi na nwere doro anya arụmọrụ uru n'ọhịa nke nnukwu-dayameta otu kristal ọkụ thermal ubi usoro.
