Mitundu ya carbon fiber reinforced resin matrix composites imawonetsa mphamvu zenizeni komanso kuuma kwake kuposa zitsulo, koma amakonda kutopa. Mtengo wamsika wazophatikiziridwa ndi kaboni fiber-reinforced resin matrix zitha kufika $31 biliyoni mu 2024, koma mtengo wamakina owunikira zaumoyo kuti muwone kuwonongeka kwa kutopa ukhoza kupitilira $5.5 biliyoni.
Kuti athetse vutoli, ofufuza akufufuza zowonjezera za nano ndi ma polima odzichiritsa okha kuti asiye ming'alu kuti isafalikire muzinthu. Mu Disembala 2021, ofufuza a ku Washington University's Rensselaer Polytechnic Institute ndi Beijing University of Chemical Technology adaganiza zopanga zinthu zokhala ndi matrix onga galasi ngati polima omwe amatha kusintha kuwonongeka kwa kutopa. Matrix a composite amapangidwa ndi ma epoxy resins ndi ma epoxy resins apadera otchedwa vitrimers. Poyerekeza ndi utomoni wamba wa epoxy, kusiyana kwakukulu pakati pa vitrifying agent ndikuti mukatenthedwa pamwamba pa kutentha kwakukulu, njira yosinthira yolumikizirana imachitika, ndipo imatha kudzikonza yokha.
Ngakhale pambuyo pa kuwononga kwa 100,000, kutopa kwamagulu kumatha kusinthidwa ndi kutentha kwanthawi ndi nthawi mpaka kupitilira 80 ° C. Kuphatikiza apo, kugwiritsa ntchito zida za kaboni kuti ziwotche zikakhala kumadera a RF electromagnetic kutha kulowetsa m'malo mwa ma heater wamba pokonza zinthu zina. Njirayi imayang'anira "kusasinthika" kwa kuwonongeka kwa kutopa ndipo imatha kubweza kapena kuchedwetsa kuwonongeka komwe kumabwera chifukwa cha kutopa kwanthawi yayitali, kukulitsa moyo wa zida zomangira ndikuchepetsa ndalama zokonzera ndi zopangira.
CARBON / SILICON CARBIDE CHIKWANGWANI chitha KUPIRIRA 3500 ° C KUCHULUKA KWAMBIRI
Kufufuza kwa lingaliro la NASA la "Interstellar Probe", motsogozedwa ndi Johns Hopkins University Applied Physics Laboratory, idzakhala ntchito yoyamba yofufuza malo opitilira mapulaneti athu ozungulira dzuwa, zomwe zimafuna kuyenda mothamanga kwambiri kuposa chombo china chilichonse. Kutali. Kuti athe kufika mtunda wautali kwambiri pa liwiro lokwera kwambiri, ma interstellar probes angafunikire kupanga "Obers maneuver," yomwe ingayendetse mlengalenga pafupi ndi dzuŵa ndi kugwiritsa ntchito mphamvu yokoka ya dzuŵa kuti ifike m'mlengalenga.
Kuti akwaniritse cholingachi, chinthu chopepuka, chotentha kwambiri chiyenera kupangidwa kuti chitetezere mphamvu ya detector ya dzuwa. Mu Julayi 2021, wopanga zida zotentha kwambiri ku America, Advanced Ceramic Fiber Co., Ltd. Ofufuzawo adatembenuza gawo lakunja lamtundu uliwonse wa kaboni fiber kukhala carbide yachitsulo monga silicon carbide (SiC / C) kudzera munjira yosinthira mwachindunji.
Ofufuzawa adayesa zitsanzozo pogwiritsa ntchito kuyesa kwa lawi ndi kutentha kwa vacuum, ndipo zidazi zidawonetsa kuthekera kwa zinthu zopepuka, zotsika kwambiri za nthunzi, kukulitsa malire apamwamba a 2000 ° C a zida za carbon fiber, ndikusunga kutentha kwina pa 3500 ° C. Mphamvu zamakina, zikuyembekezeka kugwiritsidwa ntchito mu chishango cha dzuwa cha kafukufukuyu m'tsogolomu.
