Carbon fiber reinforced resin matrix macomposites anoratidza zvirinani kusimba uye kuomarara kupfuura simbi, asi anowanzo kutadza kuneta.Iko kukosha kwemusika kwekabhoni fiber-yakasimbiswa resin matrix composite inogona kusvika mabhiriyoni makumi matatu nerimwe emadhora muna 2024, asi mutengo wehurongwa hwekutarisa hutano hwekuona kuparara kwekuneta unogona kudarika madhora mazana mashanu nemakumi mashanu emadhora.
Kuti vagadzirise dambudziko iri, vaongorori vari kuongorora nano-zvinowedzera uye kuzvirapa mapolymers kumisa mitswe kubva mukupararira mumidziyo.Muna Zvita 2021, vaongorori vepaWashington University's Rensselaer Polytechnic Institute uye Beijing University yeChemical Technology vakaronga zvinhu zvakaumbwa negirazi-senge polymer matrix inogona kudzoreredza kukuvara kwekuneta.Iyo matrix yemusanganiswa inoumbwa neyakajairwa epoxy resins uye yakakosha epoxy resins inonzi vitrimers.Kuenzaniswa neyakajairwa epoxy resin, mutsauko wakakosha pakati pevitrifying agent ndewekuti kana yapiswa pamusoro peiyo tembiricha yakakosha, inodzokororwa muchinjiko-yekubatanidza maitiro inoitika, uye inokwanisa kuzvigadzirisa pachayo.
Kunyangwe mushure memazana e100,000 ekukuvadza kutenderera, kuneta mumakompositi kunogona kudzoreredzwa nekudziya nguva nenguva kusvika kunguva inopfuura 80°C.Pamusoro pezvo, kushandisa zvimiro zvekabhoni zvinhu kupisa kana zvafumurwa kuRF electromagnetic minda kunogona kutsiva kushandiswa kweakajairika maheater ekugadzirisa zvakasarudzwa zvikamu.Iyi nzira inogadzirisa "isingagadziriswe" hunhu hwekuneta uye inogona kudzoreredza kana kunonoka kusanganiswa-kukonzeresa kukuvara kanenge nekusingaperi, kuwedzera hupenyu hwezvigadzirwa zvemagadzirirwo uye kudzikisira mari yekugadzirisa uye yekushandisa.
CARBON / SILICON CARBIDE FIBER INOGONA KUSIRIRA 3500 ° C ULTRA-YAKASI TEMPERATURE
NASA's "Interstellar Probe" pfungwa yekudzidza, inotungamirwa neJohns Hopkins University Applied Physics Laboratory, ichave yekutanga basa rekuongorora nzvimbo iri mhiri kwesolar system yedu, inoda kufamba nekukurumidza kupfuura chero imwe spacecraft.Kure.Kuti zvikwanise kusvika nzendo refu kwazvo nekumhanya kwakanyanya, ma interstellar probe angada kuita "Obers maneuver," iyo inotenderedza probe pedyo nezuva uye kushandisa simba rezuva rinokwevera zuva kupinza probe munzvimbo yakadzika.
Kuzadzisa chinangwa ichi, chinhu chakareruka, chepamusoro-chepamusoro chekushisa chinoda kugadzirwa kuitira detector's solar shield.Muna Chikunguru 2021, mugadziri wezvishandiso zvemhando yepamusoro wekuAmerica Advanced Ceramic Fiber Co., Ltd. neJohns Hopkins University Applied Physics Laboratory vakabatana kugadzira huremu, hwepamusoro-soro hwekupisa tembiricha yekeramic fiber inogona kushingirira tembiricha ye3500°C.Vatsvakurudzi vakashandura chikamu chekunze chega yega kabhoni fiber filament kuita simbi carbide yakadai sesilicon carbide (SiC / C) kuburikidza nekushandura zvakananga.
Vatsvakurudzi vakaedza masampuli vachishandisa murazvo wekuedza uye kupisa kwevacuum, uye zvinhu izvi zvakaratidza kukwanisa kwehuremu, yakaderera mhute yekumanikidza zvinhu, kuwedzera muganho wepamusoro we2000 ° C we carbon fiber zvinhu, uye kuchengetedza imwe tembiricha pa 3500 ° C.Simba remagetsi, rinotarisirwa kushandiswa munhovo yezuva ye probe mune ramangwana.
