Izinhlanganisela ze-Carbon fibre reinforced resin matrix zibonisa amandla athile angcono nokuqina kunezinsimbi, kodwa zivame ukwehluleka ukukhathala.Inani lemakethe lezinhlanganisela ze-carbon fiber-reinforced resin matrix lingafinyelela ku-$31 billion ngo-2024, kodwa izindleko zohlelo lokuqapha ezempilo oluhlelekile ukuze kutholwe umonakalo wokukhathala zingaba ngaphezulu kwezigidigidi ezingu-5.5 zamaRandi.
Ukubhekana nale nkinga, abacwaningi bahlola izithasiselo ze-nano-nano-self-healing polymers ukuze bamise imifantu ekusakazeni ezintweni.Ngo-December 2021, abacwaningi base-Washington University's Rensselaer Polytechnic Institute kanye nase-Beijing University of Chemical Technology bahlongoza into eyinhlanganisela ene-matrix ye-polymer efana nengilazi engahlehlisa umonakalo wokukhathala.I-matrix ye-composite yakhiwe ngama-epoxy resins ajwayelekile kanye nama-epoxy resins abizwa ngokuthi ama-vitrimers.Uma kuqhathaniswa ne-epoxy resin evamile, umehluko oyinhloko phakathi kwe-ejenti ye-vitrifying ukuthi lapho kushisa ngaphezu kwezinga lokushisa elibucayi, ukusabela okuhlehliswayo okuxhumanisa ukuphambana kwenzeka, futhi inamandla okuzilungisa.
Ngisho nangemva kwemijikelezo yomonakalo engu-100,000, ukukhathala ezingxenyeni ezihlanganisiwe kungahlehliswa ngokushisisa ngezikhathi ezithile kuye esikhathini esingaphezudlwana kuka-80°C.Ngaphezu kwalokho, ukuxhaphaza izakhiwo zekhabhoni ukuze zishise lapho zivezwe ezizindeni zikazibuthe ze-RF kungase kuthathe indawo yokusetshenziswa kwezishisi ezivamile ukuze kulungiswe izingxenye ezithile.Le ndlela ibhekana nemvelo "engenakulungiseka" yokulimala kokukhathala futhi ingahlehlisa noma ibambezele umonakalo oyinhlanganisela obangelwa ukukhathala cishe unomphela, inwebe impilo yezinto zokwakha futhi yehlise izindleko zokulungisa nezokusebenza.
I-CARBON / SILICON CARBIDE FIBBER INGAMELANA NO-3500 ° C IXESHA ELIPHEZULU KAKHULU
Ucwaningo lomqondo we-NASA lwe-"Interstellar Probe", oluholwa yi-Johns Hopkins University Applied Physics Laboratory, luzoba umkhankaso wokuqala wokuhlola umkhathi ngale kwesimiso sethu sonozungezilanga, odinga ukuhamba ngesivinini esisheshayo kunanoma yimuphi omunye umkhumbi-mkhathi.Kude.Ukuze ikwazi ukufinyelela amabanga amade kakhulu ngesivinini esikhulu kakhulu, ama-interstellar probe angase adinge ukwenza "i-Obers maneuver," engasondezela uphenyo eduze nelanga futhi isebenzise amandla adonsela phansi elanga ukuze ibambe uphenyo endaweni ejulile.
Ukuze kuzuzwe lo mgomo, impahla engasindi, enezinga lokushisa eliphezulu kakhulu idinga ukuthuthukiswa kwesivikelo selanga somtshina.NgoJulayi 2021, umthuthukisi wezinto zokushisa ezisezingeni eliphezulu waseMelika i-Advanced Ceramic Fiber Co., Ltd. kanye ne-Johns Hopkins University Applied Physics Laboratory basebenzisana ukuze bakhe i-ceramic fiber engasindi, enezinga lokushisa eliphezulu kakhulu ekwazi ukumelana nezinga lokushisa elingu-3500°C.Abacwaningi baguqule ungqimba lwangaphandle lwe-carbon fiber filament ngayinye ibe yi-carbide yensimbi efana ne-silicon carbide (SiC / C) ngenqubo yokuguqulwa okuqondile.
Abacwaningi bahlole amasampula besebenzisa ukuhlolwa kwelangabi nokufudumeza kwe-vacuum, futhi lezi zinto zikhombisa amandla ezinto ezingasindi, zokucindezela komhwamuko ophansi, zelula umkhawulo wamanje ongaphezulu ongu-2000 ° C wezinto ze-carbon fiber, nokugcina izinga lokushisa elithile ku-3500 ° C.Amandla omshini, kulindeleke ukuthi asetshenziswe kusihlangu selanga se-probe esikhathini esizayo.
