Masiku angapo apitawa, yunivesite ya Washington Pulofesa Aniruddddddh Vashis adasindikiza zolemba zapadziko lonse lapansi kaboni. Mosiyana ndi CFRP yachikhalidwe, yomwe siyingakonzedwe kale yowonongeka, zinthu zatsopano zitha kukonzedwa mobwerezabwereza.
Ndikusunga makina azinthu zachikhalidwe, CFRP yatsopano imawonjezera mwayi watsopano, ndiye kuti, zitha kukonzedwa mobwerezabwereza mobwerezabwereza. Kutentha kumatha kukonza kuwonongeka kwa zinthuzo, ndipo amathanso kugwiritsidwa ntchito kuwola zinthu zomwe zimafunikira kuti zibwezeredwe kumapeto kwa kuzungulira kwa ntchito. Popeza CFRP ya CFRP siyingabwezeretsedwe, ndikofunikira kukulitsa zinthu zatsopano zomwe zingabwezeretsedwe kapena kukonzedwa pogwiritsa ntchito mphamvu zamagetsi kapena kutentha kwa radio.
Pulofesa Vashis adati gwero la kutentha lingathe kuzengereza mpaka muyeso wa CFRP yatsopano. Izi zikulankhula mozama, izi ziyenera kutchedwa mafayilo a Carbon firimani (VCFRP, mpweya wounjikirayo). Galasi Politymer (Frimiria) ndi mtundu watsopano wa zinthu za polymer zomwe zimaphatikiza ma promoctics a thermoptic zosinthana ndi mafilimu a France, ndipo nthawi yomweyo amakhala ndi mawonekedwe olumikizira Ma polima amatha kudziletsa ndikudziimilanso ngati ma polima a thermoplastic.
Mosiyana ndi zimenezo, zotchulidwa monga kaboni zophatikizika ndi ma carbon firtic zolimbikitsira mitundu (cfrp), yomwe imatha kugawidwa m'mitundu iwiri: thermost kapena thermoplac molingana ndi mawonekedwe osiyanasiyana. Thermosetting Zida nthawi zambiri zimakhala ndi epoxy sliden, zomangira zamankhwala zomwe zimaphatikizanso zinthuzo kukhala thupi limodzi. Mapangidwe a thermoplastic amakhala ndi ma relo ofewa a thermoplastic omwe amatha kusungunuka ndikuwuzidwa, koma izi zimakhudzanso mphamvu ndi kuwuma kwa zinthuzo.
Zomangira zamankhwala ku VCFRP imatha kulumikizidwa, yolumikizidwa, ndikuyanjananso kuti ipeze "zapakati" pakati pa thermotset ndi mapangidwe a thermoplactic. Ofufuzawo amakhulupirira kuti mafiriji amatha kukhala olowa m'malo mwa thermoseting matermosetit ndikupewa kudzikundikira kwa ma thermosetitting mtundu. Ofufuzawo amakhulupirira kuti VCFRP idzakhala yosinthira kwambiri kuchokera ku zinthu zachikhalidwe ku zida zamphamvu za zinthu zamphamvu, ndipo zimakhala ndi zovuta zingapo motengera kudalirika kwathunthu, kudalirika, chitetezo, kukonza.
Pakadali pano, masamba amphepo ndi amodzi mwa madera omwe CFRP imagwiritsa ntchito kukula kwake, ndipo kubwezeretsa masamba kwakhala vuto m'munda uno. Kutha kwa nthawi yautumiki, masamba masauzande ambiri opuma adatayidwa mu dzimangira mu mawonekedwe a kunyamula katundu, zomwe zidapangitsa kuti chilengedwe chizikhala chovuta.
Ngati VCFRP itha kugwiritsidwa ntchito popanga tsamba, imatha kubwezeredwanso ndikugulira ndi kutentha kosavuta. Ngakhale tsamba lochititsidwayo silingakonzedwe ndikugwiritsidwanso ntchito, osachepera itha kuwola ndi kutentha. Zinthu zatsopanozi zimasinthiratu kuzungulira kwa mzere wa thermoset kumapanga mawonekedwe a cyclic munthawi ya cyclic, yomwe ikhale njira yayikulu yopitilira kukula.
