Iimbumba zekhabhon-carbonluhlobo lwe-carbon fiber composites, kunye ne-carbon fiber njengento yokuqinisa kunye nekhabhoni efakwe njenge-matrix. Imatrix yeIimbumba zeC/C yikhabhoni. Kuba iphantse yaqulunqwa ngokupheleleyo yi-carbon elemental, inokumelana nobushushu obuphezulu kwaye ifumana ilifa leepropathi ezinamandla ze-carbon fiber. Kuye kwaphuhliswa kwintsimi yokukhusela ngaphambili.
Iindawo zesicelo:
C/C imathiriyeli edibeneyozibekwe embindini wekhonkco loshishino, kwaye umlambo ubandakanya i-carbon fiber kunye ne-preform production, kunye nemimandla yesicelo esezantsi ibanzi.C/C imathiriyeli edibeneyozisetyenziswa ikakhulu njengezinto ezikwaziyo ukumelana nobushushu, imathiriyeli yokukhuhlana, kunye nemathiriyeli ephezulu yokusebenza koomatshini. Zisetyenziswa kwi-aerospace (i-rocket nozzle ye-throat linings, izinto zokukhusela i-thermal kunye ne-injini ye-thermal structural parts), izixhobo ze-brake (i-high-speed rail, i-aircraft brake discs), i-photovoltaic thermal fields (imigqomo ye-insulation, i-crucibles, iityhubhu zesikhokelo kunye nezinye izinto), imizimba yebhayoloji (amathambo enziweyo) kunye nezinye iindawo. Okwangoku, ekhayaC/C imathiriyeli edibeneyoIinkampani ikakhulu zijolise kwikhonkco elinye lezinto ezihlanganisiweyo kwaye zandise ukuya kwicala elingasentla.
Izinto ezihlanganisiweyo zeC / C zinomsebenzi oncomekayo obanzi, kunye noxinzelelo oluphantsi, amandla athile aphezulu, imodyuli ethile ephezulu, i-thermal conductivity ephezulu, i-coefficient yokwandiswa kwe-thermal ephantsi, ukuqina okuhle kokuqhekeka, ukuxhathisa ukunxiba, ukuxhathisa, njl. Ngokukodwa, ngokungafaniyo nezinye izinto, amandla ezinto ezidibeneyo zeC / C aziyi kuncipha kodwa zinokunyuka ngokunyuka kweqondo lokushisa. Yeyona nto ibalaseleyo ukumelana nobushushu, kwaye ke ngoko iqale yaveliswa kwimizi-mveliso yerokethi yomqala.
Izinto ezihlanganisiweyo zeC / C zizuza iipropati ezibalaseleyo zoomatshini kunye neepropathi zokusetyenzwa kwefayibha yekhabhoni, kwaye inokumelana nobushushu kunye nokumelana nokubola kwegraphite, kwaye ibe ngumkhuphisana oqinileyo weemveliso zegraphite. Ngokukodwa kwintsimi yesicelo eneemfuno eziphezulu zamandla - i-photovoltaic field thermal, i-cost-effectiveness kunye nokhuseleko lwe-C / C yezinto ezidibeneyo ezidibeneyo ziba zivelele ngakumbi phantsi kwee-wafers ze-silicone ezinkulu, kwaye ziye zaba yimfuno eqinile. Ngokuchasene noko, igraphite iye yaba yongezelela kwizinto ezidibeneyo zeC / C ngenxa yokunqongophala kwamandla okuvelisa kwicala lokubonelela.
Ukusetyenziswa kwe-Photovoltaic thermal field:
Intsimi ye-thermal yinkqubo yonke yokugcina ukukhula kwe-silicon ye-monocrystalline okanye ukuveliswa kwee-polycrystalline silicon ingots kwiqondo lokushisa elithile. Idlala indima ephambili kubunyulu, ukufana kunye nezinye iimpawu ze-silicon ye-monocrystalline kunye ne-silicon ye-polycrystalline, kwaye iyingxenye yangaphambili yoshishino lokuvelisa i-silicon ye-crystalline. Intsimi ye-thermal inokwahlulwa ibe yinkqubo ye-thermal field ye-monocrystalline silicon enye i-crystal yokutsala isithando somlilo kunye nenkqubo ye-thermal field ye-polycrystalline ingot isithando somlilo ngokohlobo lwemveliso. Kuba iiseli ze-silicon ze-monocrystalline zinokusebenza okuphezulu koguqulo kuneeseli ze-polycrystalline silicon, isabelo sentengiso yee-monocrystalline silicon wafers siyaqhubeka nokukhula, ngelixa isabelo sentengiso yee-polycrystalline silicon wafers kwilizwe lam besihla unyaka nonyaka, ukusuka kwi-32.5% ngo-2019 ukuya kwi-9.3% ngo-2020. Ngoko ke, abavelisi bentsimi ye-thermal basebenzisa kakhulu indlela ye-thermal field technology ye-crystal eyodwa yokutsala iifurnaces.
Umzobo 2: Intsimi ye-Thermal kwitsheyini yemveliso ye-silicon yekristali
Intsimi eshushu yenziwe ngamacandelo angaphezulu kweshumi elinesibini, kwaye amacandelo amane angundoqo asisikrobo, ityhubhu yesikhokelo, isilinda sokugquma, kunye nesifudumezi. Amacandelo ahlukeneyo aneemfuno ezahlukeneyo zezinto eziphathekayo. Lo mzobo ungezantsi ngumzobo oqingqiweyo wentsimi ye-thermal ye-silicon eyodwa yekristale. I-crucible, i-tube yesikhokelo, kunye ne-cylinder ye-insulation yi-structural parts of the thermal field system. Umsebenzi wabo ophambili kukuxhasa yonke intsimi yobushushu obuphezulu, kwaye ineemfuno eziphezulu zokuxinana, amandla, kunye nokuhanjiswa kwe-thermal. I-heater yinto yokufudumala ngokuthe ngqo kwintsimi ye-thermal. Umsebenzi wayo kukubonelela ngamandla ashushu. Ngokuqhelekileyo iyaxhathisa, ngoko ineemfuno eziphezulu zokuxhathisa izinto.
