ʻO nā hui kalapona-carbonhe ʻano o nā huila kalapona, me ka fiber carbon ka mea hoʻoikaika a waiho ʻia ke kalapona ma ke ʻano matrix. ʻO ka matrix oʻO nā hui C/C he kalapona. No ka mea, ʻaneʻane piha loa ia i ke kalapona elemental, maikaʻi loa ke kūpaʻa wela kiʻekiʻe a loaʻa iā ia nā waiwai mechanical ikaika o ka fiber carbon. Ua hana ʻia ʻo ia ma ke kahua pale ma mua.
Nā wahi noi:
Nā mea hoʻohui C/CAia ma waenakonu o ke kaulahao ʻoihana, a ʻo ka upstream e komo pū me ka carbon fiber a me ka hana preform, a ʻo nā kahua noi i lalo he ākea ākea.Nā mea hoʻohui C/CHoʻohana nui ʻia e like me nā mea wela, nā mea friction, a me nā mea hana mechanical kiʻekiʻe. Hoʻohana ʻia lākou i ka aerospace (rocket nozzle throat linings, nā mea pale wela a me nā ʻāpana ʻenehana thermal engine), nā mea hoʻoheheʻe (ke kaʻa kaʻa kiʻekiʻe, nā disc brake mokulele), nā māla wela photovoltaic (nā pahu insulation, crucibles, alakaʻi paipu a me nā mea ʻē aʻe). kino olaola (iwi artificial) a me nā māla ʻē aʻe. I kēia manawa, homeNā mea hoʻohui C/CʻO nā hui e kālele nui ana i ka loulou hoʻokahi o nā mea i hoʻohui ʻia a hoʻonui i ka ʻaoʻao preform upstream.
C/C composite mea he maikai loa ka hana, me ka haʻahaʻa haʻahaʻa, kiʻekiʻe kiko'ī ikaika, kiʻekiʻe kiko'ī modulus, kiʻekiʻe thermal conductivity, haʻahaʻa thermal hoʻonui coefficient, maikaʻi fracture toughness, aahu pale, ablation kū'ē, etc. ʻaʻole e emi ka ikaika o nā mea hoʻohui C/C akā hiki ke hoʻonui me ka piʻi ʻana o ka mahana. He mea wela maikaʻi loa ia, a no laila ua hana mua ʻia ʻo ia i loko o nā laina rocket throat.
C / C composite mea hoʻoili i ka maikaʻi loa mechanical waiwai a me ka hoʻoponopono waiwai o carbon fiber, a me ka wela a me ka corrosion kū'ē o graphite, a ua lilo i ka ikaika hoʻokūkū o graphite huahana. ʻOi loa i ka papa noi me nā koi ikaika kiʻekiʻe - photovoltaic thermal field, ke kumu kūʻai-effectiveness a me ka palekana o ka C / C composite material e lilo ana i mea nui ma lalo o nā wafers silicon nui, a ua lilo ia i koi koʻikoʻi. ʻO ka mea ʻē aʻe, ua lilo ka graphite i mea hoʻohui i nā mea hoʻohui C/C ma muli o ka liʻiliʻi o ka mana hana ma ka ʻaoʻao hoʻolako.
Hoʻohana ʻia ke kahua wela photovoltaic:
ʻO ke kahua wela ka ʻōnaehana holoʻokoʻa no ka mālama ʻana i ka ulu ʻana o ka silikon monocrystalline a i ʻole ka hana ʻana o nā polycrystalline silicon ingots i kahi mahana. He koʻikoʻi koʻikoʻi ia i ka maʻemaʻe, kūlike a me nā ʻano ʻē aʻe o ka silikon monocrystalline a me ka silikon polycrystalline, a no ka hope mua o ka ʻoihana hana hana silika crystalline. Hiki ke hoʻokaʻawale ʻia ke kahua wela i loko o ka ʻōnaehana wela o ka monocrystalline silicon single crystal pulling furnace a me ka thermal field system of polycrystalline ingot furnace e like me ke ʻano huahana. No ka mea ʻoi aku ka maikaʻi o ka hoʻololi ʻana ma mua o nā cell silicon polycrystalline, ke hoʻomau nei ka mākeke o nā wafers silicon monocrystalline, ʻoiai ke emi nei ka mākeke o nā wafers silicon polycrystalline i koʻu ʻāina i kēlā me kēia makahiki, mai 32.5% i 2019 a i 9.3%. i 2020. No laila, hoʻohana nui nā mea hana wela i ka ʻenehana kahua wela o ka huki aniani hoʻokahi nā kapuahi.
Kiʻi 2: Ke kahua wela i loko o ke kaulahao ʻoihana hana silika crystalline
Hoʻokumu ʻia ke kahua wela ma mua o hoʻokahi haneli mau ʻāpana, a ʻo nā ʻāpana ʻehā ʻo ka crucible, alakaʻi tube, insulation cylinder, a me ka mea wela. Loaʻa i nā ʻāpana like ʻole nā koi like ʻole no nā waiwai waiwai. ʻO ke kiʻi ma lalo nei he kiʻi kiʻi kiʻi o ke kahua wela o ka silika aniani hoʻokahi. ʻO ka crucible, ka paipu alakaʻi, a me ka cylinder insulation nā ʻāpana hana o ka ʻōnaehana kahua wela. ʻO kā lākou hana koʻikoʻi ke kākoʻo i ke kahua wela wela kiʻekiʻe, a loaʻa iā lākou nā koi kiʻekiʻe no ka density, ka ikaika, a me ka conductivity thermal. ʻO ka mea hoʻomehana he mea hoʻomehana pololei i loko o ke kahua wela. ʻO kāna hana ka hāʻawi ʻana i ka ikehu wela. ʻO ka mea maʻamau ka resistive, no laila he kiʻekiʻe nā koi no ka resistivity mea.
