Chifukwa chiyani Carbon fiber ikukhala yotchuka kwambiri pamsika wamagalimoto?

carbon CHIKWANGWANI (CF) ndi mtundu watsopano wa zinthu CHIKWANGWANI ndi mphamvu mkulu ndi mkulu modulus mpweya zili pamwamba 95%. Amapangidwa ndi flake graphite microcrystals ndi ulusi zina organic zakhala zikuzunza m'miyoyo motsatira malangizo axial CHIKWANGWANI ndipo analandira carbonization ndi graphitization wa microcrystalline inki zipangizo. Mpweya wa carbon ndi chinthu chatsopano chokhala ndi makina abwino kwambiri. Gawo lake ndi lochepera 1/4 la chitsulo. Mphamvu yamakokedwe ya kaboni fiber resin kompositi nthawi zambiri imakhala pamwamba pa 3500Mpa, yomwe ndi 7 ~ 9 nthawi yachitsulo. Koma zida za kaboni zokhala ndi fiber axis zimangowonetsa kulimba kwambiri, kukana kwake kumakhala kocheperako komanso kosavuta kuwononga, chifukwa chake kupanga zida zamapangidwe nthawi zambiri kumagwiritsa ntchito mwayi wake wopepuka komanso kupewa kukhudza mbali.

Ndi kafukufuku wamaphunziro kuchokera ku fiber yaifupi ya carbon fiber kupita ku fiber yautali ya kaboni, ukadaulo, ndi zinthu zomwe zimagwiritsa ntchito mpweya wa kaboni kupanga zida zotenthetsera zalowa pang'onopang'ono m'magulu ankhondo ndi aboma. Magalimoto a carbon fiber composites atha kugwiritsidwa ntchito ngati ma shaft amagalimoto, akasupe a mbale, mafelemu, ndi ma brake pads. Pakalipano, zipangizo zachitsulo zimakhala pafupifupi 3/4 ya kulemera kwa galimoto. Zigawo zonse zazitsulo zagalimoto zikadasinthidwa ndi zida za carbon fiber, kulemera kwa galimoto kumachepetsedwa ndi 300kg, mphamvu yamafuta ikadakwera ndi 36%, ndipo utsi wa carbon dioxide udachepetsedwa ndi 17%.

1. Kugwiritsiridwa ntchito kwa thupi lagalimoto ndi chassis, chifukwa kaboni fiber yowonjezeredwa ndi ma polima opangidwa ndi polima imakhala ndi mphamvu zokwanira komanso kuuma, ndiye chinthu chopepuka kwambiri popanga zigawo zazikulu zamagalimoto monga matupi agalimoto ndi chassis. AKUTI KUPWIRITSA NTCHITO KWA CARBON FIBER COMPOSITE MATERIAL KUTHA KUCHEPETSA KUSINTHA KWA GALIMOTO ndi chassis ndi 40% ~ 60%, zomwe ndi zofanana ndi 1/3 ~ 1/6 ya Unyinji wa chitsulo. Magalimoto amtundu wanthawi zonse komanso magalimoto osinthidwa pang'ono onse ndi awa, ndipo mawonekedwe ake ndiabwino kwambiri komanso ozizira kwambiri.

2. Kugwiritsa ntchito ma brake pads, mpweya wa kaboni umagwiritsidwanso ntchito pa ma brake pads chifukwa chachitetezo chake cha chilengedwe komanso mawonekedwe ake osavala, koma zinthu zomwe zimakhala ndi zida za carbon fiber zili pamwamba, kotero mtundu uwu wa brake pad umagwiritsidwa ntchito kwambiri magalimoto apamwamba. Carbon fiber brake discs amagwiritsidwa ntchito kwambiri pamagalimoto othamanga, monga magalimoto a F1. Ikhoza kuchepetsa liwiro la galimoto kuchokera ku 300 km / h mpaka 50 km / h pamtunda wa 50 m, panthawi yomwe kutentha kwa brake disc kudzakwera kuposa 900 ℃, ndipo brake disc idzakhala yofiira chifukwa. imatenga mphamvu zambiri za kutentha. Ma disks a carbon fiber brake amatha kupirira kutentha mpaka 2 500 ° C ndikupereka kukhazikika bwino kwa braking.

3, kugwiritsa ntchito ma wheel hub, akatswiri opanga ma wheel hub ku Germany adayambitsa ma gudumu, kutengera kapangidwe ka zidutswa ziwiri, mphete yakunja imapangidwa ndi zinthu za kaboni, ndipo mkati mwake ndi aloyi wopepuka, wokhala ndi zomangira zitsulo zosapanga dzimbiri, poyerekeza ndi ambiri kukula kwa gudumu kulemera ndi za 40% m'munsi. Mwachitsanzo, kanyumba kakang'ono ka mainchesi 20 kamalemera 6 kg, pomwe kanyumba kakang'ono kamalemera pafupifupi 18 kg. Magudumu apadera amtundu wa RX-X opangidwa ndi Kahm waku Britain pogwiritsa ntchito CFRP ali ndi kulemera kwa 6 kg yokha, yomwe imatha kuthamanga kwambiri ndikuchepetsa mphamvu ya ma radial inertia ya gudumu. Wopangidwa ndi DYMAG ku UK, gudumu lopepuka kwambiri padziko lonse lapansi la carbon fiber/magnesium lili ndi magawo awiri, ma wheel fiber mesh, ndi magnesium brake disc, yolumikizidwa ndi zida zapadera zopukutidwa ndi titaniyamu.

4, kuyendetsa shaft kugwiritsira ntchito mphamvu ya shaft yoyendetsa galimoto kumakhala kovuta kwambiri, makamaka iyenera kukhala ndi torque yayikulu, kuganizira mozama za carbon CHIKWANGWANI kulimbikitsa gulu la zinthu anisotropy, mphamvu mkulu, ndi modulus makhalidwe ndi otsika, motero ntchito mpweya CHIKWANGWANI. analimbitsa gulu kufala kutsinde m'malo zinthu zitsulo, kukwaniritsa chofunika ntchito. Carbon fiber driveshaft sikuti imangochepetsa kulemera ndi 60% komanso imakhala ndi kukana kutopa komanso kulimba.

Bola kugwiritsa ntchito mpweya wa kaboni m'galimoto ndikukwaniritsa zopepuka zagalimoto ndikukwaniritsa zofuna zolimba zagalimoto, sikungakwaniritse zofuna zapadziko lonse lapansi pakupulumutsa mphamvu ndi kuchepetsa umuna komanso kuthana ndi vuto la kupulumutsa mafuta. zokhudzana ndi Volkswagen.
