Kwiintsuku ezimbalwa ezidlulileyo, unjingalwazi weYunivesithi yaseWashington u-Aniruddh Vashisth wapapasha iphepha kwiphephancwadi eligunyazisiweyo lamazwe ngamazwe iCarbon, ebanga ukuba uye waphuhlisa ngempumelelo uhlobo olutsha lwe-carbon fiber composite material.Ngokungafaniyo ne-CFRP yemveli, engenakulungiswa xa yonakele, izinto ezintsha zinokulungiswa ngokuphindaphindiweyo.
Ngelixa ugcina iimpawu zoomatshini bezinto zemveli, iCFRP entsha yongeza inzuzo entsha, oko kukuthi, inokulungiswa ngokuphindaphindiweyo phantsi kwesenzo sobushushu.Ukushisa kunokulungisa nawuphi na umonakalo wokudinwa kwezinto, kwaye kungasetyenziselwa ukubola izinto xa kufuneka zihlaziywe ekupheleni komjikelo wenkonzo.Kuba iCFRP yemveli ayinakuphinda isetyenziswe, kubalulekile ukuphuhlisa imathiriyeli entsha enokuphinda isetyenziswe okanye ilungiswe kusetyenziswa amandla ashushu okanye ukufudumeza amaza kanomathotholo.
Unjingalwazi uVashisth uthe umthombo wobushushu unokulibazisa ngokungenammiselo inkqubo yokuguga yeCFRP entsha.Ukuthetha ngokuthe ngqo, le nto kufuneka ibizwe ngokuba yiCarbon Fiber Reinforced Vitrimers (vCFRP, Carbon Fiber Reinforced Vitrimers).Ipolymer yeglasi (Vitrimers) luhlobo olutsha lwemathiriyeli yepolymer edibanisa izibonelelo ze-thermoplastic kunye ne-thermosetting plastics eyenziwe ngusosayensi waseFransi uNjingalwazi uLudwik Leibler ngo-2011. Izinto zeVitrimers zisebenzisa indlela yokutshintshiselana ngebhondi eguqukayo, enokwenza utshintshiselwano lwekhemikhali olubuyiselwa umva ngendlela eguquguqukayo. xa ushushu, kwaye kwangaxeshanye ugcine ulwakhiwo oludityanisiweyo lulonke, ukwenzela ukuba iipolymers ze-thermosetting zikwazi ukuziphilisa kwaye ziphinde zenziwe kwakhona njenge-polymers thermoplastic.
Ngokwahlukileyo, izinto eziqhele ukubizwa ngokuba yi-carbon fibre composite materials are carbon fibre reinforced resin matrix composite materials (CFRP), ezinokuthi zahlulwe zibe zintlobo ezimbini: thermoset okanye thermoplastic ngokwesakhiwo sentlaka esahlukileyo.Izinto ezihlanganisiweyo ze-Thermosetting zihlala zine-epoxy resin, iibhondi zeekhemikhali ezinokuthi zidibanise ngokusisigxina izinto zibe ngumzimba omnye.Iicomposites ze-Thermoplastic ziqulethe i-resins ye-thermoplastic ethambileyo enokuthi inyibilike kwaye ihlaziywe, kodwa oku kuya kuchaphazela ngokuqinisekileyo amandla kunye nokuqina kwezinto.
Iibhondi zemichiza kwi-vCFRP zinokudityaniswa, ziqhawulwe, kwaye ziphinde ziqhagamshelwe ukufumana "umhlaba ophakathi" phakathi kwe-thermoset kunye nezixhobo ze-thermoplastic.Abaphandi beProjekthi bakholelwa ukuba iiVitrimers zinokuthatha indawo ye-thermosetting resins kwaye zithintele ukuqokelelana kwe-thermosetting composite kwiindawo zokulahla inkunkuma.Abaphandi bakholelwa ukuba i-vCFRP iya kuba yinguqu enkulu ukusuka kwimathiriyeli yemveli ukuya kwizinto eziguqukayo, kwaye iya kuba nothotho lweempembelelo malunga neendleko ezipheleleyo zomjikelo wobomi, ukuthembeka, ukhuseleko, kunye nokugcinwa.
Okwangoku, iiblade ze-injini yomoya yenye yeendawo apho ukusetyenziswa kwe-CFRP kukhulu, kwaye ukubuyiswa kwee-blades bekusoloko kuyingxaki kulo mmandla.Emva kokuphela kwexesha lenkonzo, amawaka eentsimbi ezithathe umhlala-phantsi alahlwa kwindawo yokulahla inkunkuma ngendlela yokulahla inkunkuma, eyabangela impembelelo enkulu kwindalo esingqongileyo.
Ukuba i-vCFRP ingasetyenziselwa ukwenza i-blade, inokuphinda isetyenziswe kwaye isetyenziswe ngokufudumeza okulula.Nokuba incakuba enyangweyo ayinakulungiswa kwaye iphinde isetyenziswe, ubuncinci inokubola ngenxa yobushushu.Isixhobo esitsha siguqula umjikelo wobomi bomjikelo we-thermoset composite ibe ngumjikelo wobomi bomjikelo, oya kuba linyathelo elikhulu elibhekiselele kuphuhliso oluzinzileyo.
