Kwiintsuku nje ezimbalwa ezidlulileyo, iYunivesithi yaseWashington Pesissol Abiruddh vashisti yapapasha iphepha kwi-joreristal jorbon yamanye amazwe, ebanga ukuba aphuhlise ngempumelelo uhlobo olutsha lwe-carbon fiber fiber. Ngokungafaniyo ne-CFRP yendabuko, engenako ukulungiswa xa yonakaliswe, izixhobo ezitsha zinokulungiswa ngokuphindaphindiweyo.
Ngelixa ugcina iipropathi zoomatshini wezinto zemveli, i-CFRP entsha yongeza inzuzo entsha, oko kukuthi, inokulungiswa ngokuphindaphindiweyo phantsi kwesenzo sobushushu. Ubushushu bunokulungisa nakuphi na ukutyeshelwa kokukhathalela kwezinto, kwaye kunokusetyenziselwa ukubola umxholo xa kufuneka kuphinde kwakhona ukuphinda usebenze ekupheleni komjikelo wenkonzo. Kuba i-CFRP yendabuko ayinakuphinda isebenze, kubalulekile ukukhulisa izinto ezintsha ezinokuthi ziphinde zisebenze okanye zilungiswe kusetyenziswa amandla e-thermal okanye irediyo yerediyo.
Unjingalwazi uVashisth wathi umthombo wobushushu unokulibazisa ngenkqubo yokwalupha ye-CFRP entsha. Ngokuthetha ngokungqongqo, ezi zinto kufuneka zibizwa ngokuba yi-Carbon Fiber Reiriments viturser (VCFRP, i-Carbon Fiber eqingqiweyo). I-prolymer yeglasi (i-viturimers) luhlobo olutsha lwezinto eziluncedo kwi-thermoplastic kunye ne-therstimset ye-procimil ye-proses, kwaye kwangaxeshanye zisebenzisa i-prosestral proces genes. I-thermosers polymers inokuba ngokwakho impiliso kwaye iphinde inyikima njengee-thermoplastic polymers.
Ngokwahlukileyo koko, izinto ebezihlala zibizwa ngokuba zizixhobo ze-carbon fiber yi-carbon fiber i-fiber eqinisa izixhobo (i-CFRP), enokwahlulwa kwi-thermoples ngokwesakhiwo esahlukileyo se-resin. Izinto ezihlanganisiweyo zeTramoset zihlala zine-epoxy resin, amaqhina ekhemikhali apho anokuhlanganisa ngokupheleleyo izinto kumzimba omnye. I-Thertolistic Composites iqukethe i-resist ethambileyo ye-thermoplaritistic ethambileyo enokunyibilikiswa kwaye inyikima, kodwa oku kuya kuchaphazela amandla kunye nokuqina kwento leyo.
Iibhondi zemichiza kwi-VCFRP zinokuqhagamshelwa, zikhutshiwe, kwaye ziphinde ziphinde ziphinde zifumane "umhlaba ophakathi" phakathi kwe-thermoset kunye ne-thermoplatistic. Abaphandi beprojekthi bakholelwa ukuba ii-vitrimes zinokubambelela ekuthinteleni i-therimowset kwaye zithintele ukuqokelelwa kwezinto ezihlanganisiweyo ze-therimowuting kwi-LandFill. Abaphandi bakholelwa ukuba i-VCFRP iya kuba lutshintsho olukhulu kwizinto zesiko kwizinto ezinamandla, kwaye ziya kuba nothotho lweempembelelo ngokweendleko zomjikelezo wobomi, ukuthembeka, ukhuseleko, kunye nokugcinwa.
Okwangoku, iibhloko ze-turbine zomoya zenye yeendawo apho ukusetyenziswa kwe-CFRP inkulu, kwaye ukubuyiselwa kwamabala bekusoloko kuyingxaki kule ndawo. Emva kokuphelelwa kwexesha lenkonzo, amawaka eebhlorho ezazithathe umhlala phantsi alahliwe kwilayibransi yomhlaba ngohlobo lwempilo engqongileyo, ebangela ifuthe elikhulu kwindalo esingqongileyo.
Ukuba i-VCFRP inokusetyenziselwa ukuvelisa i-blade, inokuphinda isebenze kwaye isetyenziswe ngokufudumeza ngokulula. Nokuba blade ophathwayo alunakulungiswa kwaye baphinde baphinde basetyenziswe, ubuncinci bunokungabikho bubushushu. Ezona zinto zibalulekileyo ziguqula umjikelo wobomi obumqolo we-thermoset ye-thermoset kumjikelo wobomi bukaSyclic, oya kuba linyathelo elikhulu ukuya kuphuhliso oluzinzileyo.
