Masiku angapo apitawo, pulofesa wa pa yunivesite ya Washington, Aniruddh Vashisth, adasindikiza pepala m'magazini yapadziko lonse ya Carbon, ponena kuti adapanga bwino mtundu watsopano wa carbon fiber composite material.Mosiyana ndi CFRP yachikhalidwe, yomwe singathe kukonzedwa ikawonongeka, zida zatsopano zimatha kukonzedwa mobwerezabwereza.
Ngakhale kusunga makina azinthu zachikhalidwe, CFRP yatsopano imawonjezera mwayi watsopano, ndiye kuti, imatha kukonzedwa mobwerezabwereza pansi pa kutentha.Kutentha kumatha kukonza kutopa kulikonse kwa zinthuzo, komanso kungagwiritsidwe ntchito kuwola zinthuzo zikafunika kubwezeretsedwanso kumapeto kwa ntchitoyo.Popeza CFRP yachikhalidwe sichingasinthidwenso, ndikofunikira kupanga zatsopano zomwe zitha kubwezeretsedwanso kapena kukonzedwanso pogwiritsa ntchito mphamvu yamafuta kapena kutenthetsa pafupipafupi kwa wailesi.
Pulofesa Vashisth adanena kuti gwero la kutentha limatha kuchedwetsa kukalamba kwa CFRP yatsopano.Kunena zowona, izi ziyenera kutchedwa Carbon Fiber Reinforced Vitrimers (vCFRP, Carbon Fiber Reinforced Vitrimers).Glass polima (Vitrimers) ndi mtundu watsopano wa zinthu za polima zomwe zimaphatikiza ubwino wa mapulasitiki a thermoplastic ndi thermosetting opangidwa ndi wasayansi wa ku France Pulofesa Ludwik Leibler mu 2011. ukatenthedwa, ndipo nthawi yomweyo sungani mawonekedwe olumikizana ndi mtanda wonse, kuti ma polima a thermosetting azitha kudzichiritsa okha ndikusinthidwanso ngati ma polima a thermoplastic.
Mosiyana ndi izi, zinthu zomwe zimatchedwa carbon fiber composite materials ndi carbon fiber reinforced resin matrix composite materials (CFRP), zomwe zingathe kugawidwa m'magulu awiri: thermoset kapena thermoplastic malinga ndi mawonekedwe a utomoni wosiyana.Zida zophatikizika za thermosetting nthawi zambiri zimakhala ndi epoxy resin, zomangira zamakemikolo zomwe zimatha kuphatikiza zinthuzo kukhala thupi limodzi.Ma composites a thermoplastic amakhala ndi utomoni wofewa wa thermoplastic womwe ungasungunuke ndikusinthidwanso, koma izi zidzakhudza mphamvu ndi kuuma kwa zinthuzo.
The zomangira mankhwala mu vCFRP akhoza kulumikizidwa, kuchotsedwa, ndi kulumikizanso kupeza "pakati" pakati pa thermoset ndi zipangizo thermoplastic.Ofufuza a polojekiti amakhulupirira kuti ma Vitrimers amatha kukhala m'malo mwa ma resins a thermosetting ndikupewa kudzikundikira kwa ma thermosetting composites m'malo otayira.Ochita kafukufuku amakhulupirira kuti vCFRP idzakhala kusintha kwakukulu kuchokera ku zipangizo zachikhalidwe kupita ku zipangizo zosunthika, ndipo zidzakhala ndi zotsatira zambiri zokhudzana ndi mtengo wamoyo wonse, kudalirika, chitetezo, ndi kukonza.
Pakadali pano, masamba opangira magetsi ndi amodzi mwamalo omwe kugwiritsidwa ntchito kwa CFRP kuli kwakukulu, ndipo kubwezeretsanso masamba kwakhala vuto nthawi zonse.Pambuyo pa kutha kwa nthawi yautumiki, masamba zikwizikwi omwe adapuma pantchito adatayidwa m'malo otayirapo ngati malo otayira, zomwe zidasokoneza kwambiri chilengedwe.
Ngati vCFRP itha kugwiritsidwa ntchito popanga masamba, ikhoza kusinthidwanso ndikugwiritsidwanso ntchito ndi Kutentha kosavuta.Ngakhale ngati tsambalo silingakonzedwenso ndi kugwiritsiridwanso ntchito, mwina likhoza kuwola chifukwa cha kutentha.Zatsopanozi zimasintha mizere ya moyo wamagulu a thermoset kukhala cyclic life cycle, yomwe idzakhala gawo lalikulu lachitukuko chokhazikika.
