Njira yatsopano yokhathamiritsa ndiyothandiza popanga zida zopepuka za kaboni fiber

Mpweya ndi wofunikira kuti zamoyo zonse zikhale ndi moyo, chifukwa umapanga maziko a mamolekyu onse, ndipo mamolekyu a organic amapanga maziko a zamoyo zonse.Ngakhale izi zokha ndi zochititsa chidwi, ndi chitukuko cha mpweya wa carbon, posachedwapa wapeza ntchito zatsopano zodabwitsa muzamlengalenga, zomangamanga ndi zina.Mpweya wa carbon ndi wamphamvu, wolimba komanso wopepuka kuposa chitsulo.Chifukwa chake, mpweya wa kaboni walowa m'malo mwazitsulo pazinthu zogwira ntchito kwambiri monga ndege, magalimoto othamanga ndi zida zamasewera.

Ulusi wa kaboni nthawi zambiri umaphatikizidwa ndi zinthu zina kuti apange kompositi.Chimodzi mwazinthu zophatikizika ndi carbon fiber reinforced plastics (CFRP), yomwe imadziwika ndi kulimba kwake, kuuma kwake komanso kulimba kwambiri pakulemera kwake.Chifukwa cha zofunikira kwambiri zamagulu a carbon fiber, ofufuza achita maphunziro angapo kuti apititse patsogolo mphamvu za kaboni fiber composites, ambiri omwe amayang'ana kwambiri luso lapadera lotchedwa "fiber oriented design", lomwe limapangitsa kuti mphamvuyo ikhale yabwino popititsa patsogolo kayendetsedwe kake. ulusi.

Ofufuza a ku yunivesite ya Tokyo ya sayansi atengera njira yopangira kaboni fiber yomwe imakulitsa mawonekedwe ndi makulidwe a ulusi, potero kulimbikitsa mphamvu zamapulasitiki olimba ndi kupanga mapulasitiki opepuka popanga, zomwe zimathandiza kupanga ndege zopepuka komanso magalimoto.

Komabe, njira yopangira chiwongolero cha fiber ilibe zolakwika.Mapangidwe a kalozera wa CHIKWANGWANI amangokhathamiritsa komwe akulowera ndikusunga makulidwe ake, zomwe zimalepheretsa kugwiritsa ntchito makina onse a CFRP.Dr ryyosuke Matsuzaki wa ku Tokyo University of Science (TUS) akufotokoza kuti kafukufuku wake amayang'ana kwambiri zinthu zopangidwa.

M'nkhaniyi, Dr. Matsuzaki ndi anzake Yuto Mori ndi Naoya kumekawa mu tus akufuna njira yatsopano yopangira, yomwe ingathe kuwongolera nthawi imodzi komanso makulidwe a ulusi malinga ndi malo awo mumagulu ophatikizana.Izi zimawathandiza kuchepetsa kulemera kwa CFRP popanda kusokoneza mphamvu zake.Zotsatira zawo zimasindikizidwa mu nyuzipepala ya kompositi.

Njira yawo ili ndi njira zitatu: kukonzekera, kubwerezabwereza, ndi kusinthidwa.Pokonzekera, kusanthula koyambirira kumachitika pogwiritsa ntchito njira yomalizira (FEM) kuti mudziwe kuchuluka kwa zigawo, ndikuwunika koyezera kulemera kumakwaniritsidwa kudzera mu kalozera wa fiber lamination lamination ndi mtundu wakusintha makulidwe.Kuwongolera kwa fiber kumatsimikiziridwa ndi chitsogozo cha kupsinjika kwakukulu ndi njira yobwerezabwereza, ndipo makulidwe ake amawerengedwa ndi chiphunzitso chachikulu cha kupsinjika maganizo.Pomaliza, kusintha ndondomeko kusintha akawunti kwa manufacturability, choyamba pangani buku la "base CHIKWANGWANI mtolo" m'dera limene limafuna mphamvu yowonjezera, ndiyeno kudziwa komaliza ndi makulidwe a dongosolo CHIKWANGWANI mtolo, iwo kufalitsa phukusi mbali zonse za umboni.

Pa nthawi yomweyo, njira wokometsedwa akhoza kuchepetsa kulemera ndi oposa 5%, ndi kupanga kusamutsa katundu bwino kuposa kugwiritsa ntchito CHIKWANGWANI orientation yekha.

Ofufuza ali okondwa ndi zotsatirazi ndipo akuyembekeza kugwiritsa ntchito njira zawo kuti achepetsenso kulemera kwa zigawo zachikhalidwe za CFRP mtsogolo.Dr. Matsuzaki adanena kuti njira yathu yopangira mapangidwe imapitirira kuposa mapangidwe achikhalidwe kuti apange ndege zopepuka ndi magalimoto, zomwe zimathandiza kusunga mphamvu ndi kuchepetsa mpweya wa carbon dioxide.
