Caribre fibre yongerewe imbaraga za resin matrix yerekana imbaraga zihariye kandi zikomeye kuruta ibyuma, ariko bikunda kunanirwa umunaniro.Agaciro k'isoko rya karuboni fibre-yongerewe imbaraga za resin matrix ishobora kugera kuri miliyari 31 z'amadolari mu 2024, ariko ikiguzi cya sisitemu yo kugenzura ubuzima mu rwego rwo kumenya ibyangiritse ku munaniro gishobora kurenga miliyari 5.5.
Kugira ngo iki kibazo gikemuke, abashakashatsi barimo gushakisha nano-yongeramo na polymers yo kwikiza kugirango bahagarike ibice bikwirakwizwa mu bikoresho.Ukuboza 2021, abashakashatsi bo muri kaminuza ya Washington ya Rensselaer Polytechnic Institute na kaminuza ya Beijing y’ikoranabuhanga ry’imiti basabye ko hajyaho ibintu byinshi hamwe n’ikirahure kimeze nka polymer matrix gishobora guhindura ibyangiritse.Matrisa yibigize igizwe na epoxy isanzwe hamwe na epoxy idasanzwe yitwa vitrimers.Ugereranije na epoxy resin isanzwe, itandukaniro ryingenzi hagati ya vitrifying agent ni uko iyo ushyutswe hejuru yubushyuhe bukabije, reaction ihinduka ihindagurika, kandi ifite ubushobozi bwo kwikosora.
Ndetse na nyuma yo kwangirika 100.000, umunaniro wibigize urashobora guhindurwa nubushyuhe burigihe kugeza hejuru ya 80 ° C.Byongeye kandi, gukoresha umutungo wibikoresho bya karubone kugirango ushushe mugihe uhuye na RF electromagnetic yumurima birashobora gusimbuza ikoreshwa ryubushyuhe busanzwe bwo guhitamo gusana ibice.Ubu buryo bukemura ibibazo "bidasubirwaho" byangiza umunaniro kandi birashobora guhindura cyangwa gutinza ibyangiritse biterwa numunaniro biterwa nigihe kitarambiranye, byongerera ubuzima ibikoresho byubatswe no kugabanya kubungabunga no gukoresha amafaranga yo gukora.
CARBON / SILICON CARBIDE FIBER IRASHOBORA KUBA 3500 ° C ULTRA-HIGH TEMPERATURE
Ubushakashatsi bwakozwe na NASA "Interstellar Probe", buyobowe na Laboratwari ya kaminuza ya Johns Hopkins ya Laboratwari, buzaba ubutumwa bwa mbere bwo gucukumbura ikirere kirenze izuba ryacu, gisaba ingendo ku muvuduko wihuse kuruta ibindi byogajuru byose.Kure.Kugirango ubashe kugera ku ntera ndende cyane ku muvuduko mwinshi cyane, iperereza ry’inyenyeri rishobora gukenera gukora "Obers maneuver," ryahindura iperereza hafi yizuba kandi rigakoresha uburemere bwizuba kugira ngo iperereza ryinjire mu kirere.
Kugira ngo iyi ntego igerweho, hagomba gutegurwa ibikoresho byoroheje cyane by’ubushyuhe bwo hejuru kugira ngo bikoreshe izuba.Muri Nyakanga 2021, Umunyamerika wateguye ibikoresho byo mu rwego rwo hejuru y’ubushakashatsi bwa Advanced Ceramic Fiber Co., Ltd. hamwe na Laboratwari ya kaminuza ya Johns Hopkins yafatanyijemo gukora fibre yoroheje, y’ubushyuhe bwo hejuru cyane bwo mu kirere ishobora kwihanganira ubushyuhe bwo hejuru bwa 3500 ° C.Abashakashatsi bahinduye igice cyo hanze cya buri fibre fibre fibre mo karbide yicyuma nka karubide ya silicon (SiC / C) binyuze muburyo bwo guhindura ibintu.
Abashakashatsi bapimye ingero bakoresheje ibizamini bya flame no gushyushya vacuum, kandi ibyo bikoresho byerekanaga ubushobozi bw’ibikoresho by’umuvuduko ukabije w’umuyaga mwinshi, byongerera urugero hejuru ya 2000 ° C ibikoresho bya fibre fibre, kandi bikomeza ubushyuhe runaka kuri 3500 ° C.Imbaraga za mashini, biteganijwe ko zizakoreshwa mu nkinzo yizuba ya probe mugihe kizaza.
