Mu nthawi yamakono ya kupita patsogolo kwaukadaulo mwachangu, zinthu zopangidwa ndi ulusi wa kaboni zikupanga dzina m'magawo osiyanasiyana chifukwa cha magwiridwe antchito awo apamwamba. Kuyambira kugwiritsa ntchito bwino kwambiri mumlengalenga mpaka zosowa za tsiku ndi tsiku za zinthu zamasewera, zinthu zopangidwa ndi ulusi wa kaboni zawonetsa kuthekera kwakukulu. Komabe, pokonzekera zinthu zopangidwa ndi ulusi wa kaboni zomwe zimagwira ntchito bwino kwambiri, chithandizo choyambitsaulusi wa kabonindi sitepe yofunika kwambiri.
Chithunzi cha maikulosikopu ya elekitironi pamwamba pa ulusi wa kaboni
Ulusi wa kaboni, womwe ndi ulusi wothandiza kwambiri, uli ndi zinthu zambiri zochititsa chidwi. Umapangidwa makamaka ndi kaboni ndipo uli ndi kapangidwe kaulusi wautali. Poganizira kapangidwe ka pamwamba, pamwamba pa ulusi wa kaboni ndi posalala ndipo pali magulu ochepa ogwira ntchito. Izi zili choncho chifukwa chakuti panthawi yokonzekera ulusi wa kaboni, kutentha kwambiri kwa kaboni ndi njira zina zochiritsira zimapangitsa kuti pamwamba pa ulusi wa kaboni pakhale poyera. Kapangidwe ka pamwamba kameneka kamabweretsa zovuta zambiri pakukonzekera ulusi wa kaboni.
Pamwamba pake posalala pamapangitsa kuti mgwirizano pakati pa ulusi wa kaboni ndi zinthu za matrix ukhale wofooka. Pokonzekera zinthu zophatikizika, zimakhala zovuta kuti zinthu za matrix zipange mgwirizano wolimba pamwamba paulusi wa kaboni, zomwe zimakhudza magwiridwe antchito onse a zinthu zophatikizika. Kachiwiri, kusowa kwa magulu ogwira ntchito kumachepetsa momwe mankhwala amachitira pakati pa ulusi wa kaboni ndi zinthu za matrix. Izi zimapangitsa kuti kulumikizana pakati pa ziwirizi kudalira kwambiri zotsatira zakuthupi, monga kuyika makina, ndi zina zotero, zomwe nthawi zambiri sizimakhala zokhazikika mokwanira ndipo zimatha kupatukana zikakumana ndi mphamvu zakunja.
Chithunzi chojambula cha kulimbitsa nsalu ya ulusi wa kaboni pogwiritsa ntchito ma nanotubes a kaboni
Pofuna kuthetsa mavutowa, chithandizo choyambitsa ulusi wa kaboni chimakhala chofunikira.ulusi wa kabonikusonyeza kusintha kwakukulu m'mbali zingapo.
Chithandizo choyambitsa chimawonjezera kuuma kwa ulusi wa kaboni pamwamba. Kudzera mu okosijeni wa mankhwala, chithandizo cha plasma ndi njira zina, mabowo ang'onoang'ono ndi mipata imatha kujambulidwa pamwamba pa ulusi wa kaboni, zomwe zimapangitsa kuti pamwamba pake pakhale kouma. Malo ouma awa amawonjezera malo olumikizirana pakati pa ulusi wa kaboni ndi zinthu za substrate, zomwe zimapangitsa kuti mgwirizano wamakina ukhale wabwino pakati pa ziwirizi. Zinthu za matrix zikalumikizidwa ku ulusi wa kaboni, zimatha kudzilowetsa m'mapangidwe ouma awa, ndikupanga mgwirizano wolimba.
Chithandizo choyambitsa chimatha kuyambitsa magulu ambiri ogwira ntchito omwe amagwira ntchito pamwamba pa ulusi wa kaboni. Magulu ogwira ntchito awa amatha kuchitapo kanthu mwa mankhwala ndi magulu ogwira ntchito omwe ali mu matrix kuti apange ma bond a mankhwala. Mwachitsanzo, chithandizo cha okosijeni chimatha kuyambitsa magulu a hydroxyl, magulu a carboxyl ndi magulu ena ogwira ntchito pamwamba pa ulusi wa kaboni, omwe amatha kuchitapo kanthu ndiepoxymagulu mu resin matrix ndi zina zotero kuti apange ma covalent bonds. Mphamvu ya ma chemical bond iyi ndi yayikulu kwambiri kuposa ya physical bonding, zomwe zimapangitsa kwambiri interfacial bonding strength pakati pa carbon fiber ndi matrix matrix material.
Mphamvu ya pamwamba ya ulusi wa kaboni wopangidwa ndi activated imawonjezekanso kwambiri. Kuwonjezeka kwa mphamvu ya pamwamba kumapangitsa kuti ulusi wa kaboni unyowe mosavuta ndi zinthu za matrix, motero zimathandiza kufalikira ndi kulowa kwa zinthu za matrix pamwamba pa ulusi wa kaboni. Pokonzekera zinthu zophatikizika, zinthu za matrix zimatha kugawidwa mofanana mozungulira ulusi wa kaboni kuti zipange kapangidwe kolimba kwambiri. Izi sizimangowonjezera mphamvu zamakina a zinthu zophatikizika, komanso zimawonjezera mphamvu zake zina, monga kukana dzimbiri ndi kukhazikika kwa kutentha.
Ulusi wa kaboni wopangidwa ndi activated uli ndi ubwino wambiri pakukonzekera zinthu zopangidwa ndi ulusi wa kaboni.
Ponena za katundu wa makina, mphamvu yolumikizirana pakati pa chogwirira ntchitoulusi wa kabonindipo zinthu za matrix zimakonzedwa bwino kwambiri, zomwe zimathandiza kuti zinthu zopangidwa ndi ma composites zizitha kunyamula bwino mphamvu zikagwiritsidwa ntchito ndi mphamvu zakunja. Izi zikutanthauza kuti mphamvu ndi modulus zimakonzedwa bwino kwambiri. Mwachitsanzo, m'munda wa ndege, womwe umafuna mphamvu zambiri zamakina, ziwalo za ndege zopangidwa ndi zinthu zopangidwa ndi ulusi wa kaboni wopangidwa ndi activated carbon zimatha kupirira katundu wochuluka wouluka ndikuwonjezera chitetezo ndi kudalirika kwa ndege. M'munda wa zinthu zamasewera, monga mafelemu a njinga, makalabu a gofu, ndi zina zotero, zinthu zopangidwa ndi ulusi wa kaboni wopangidwa ndi activated carbon zimatha kupereka mphamvu ndi kuuma bwino, pomwe zimachepetsa kulemera ndikukweza luso la othamanga.
Ponena za kukana dzimbiri, chifukwa cha kuyambitsidwa kwa magulu ogwira ntchito omwe amagwira ntchito pamwamba pa ulusi wa kaboni wogwiritsidwa ntchito, magulu ogwira ntchito awa amatha kupanga mgwirizano wolimba wa mankhwala ndi zinthu za matrix, motero kumawonjezera kukana kwa dzimbiri kwa zinthu zophatikizika. Mu nyengo zina zovuta zachilengedwe, monga chilengedwe cha m'nyanja, makampani opanga mankhwala, ndi zina zotero, zomwe zimayambitsidwazosakaniza za ulusi wa kabonizimatha kuletsa kuwonongeka kwa zinthu zowononga ndikuwonjezera moyo wa ntchito. Izi ndizofunikira kwambiri pazida zina ndi zomangamanga zomwe zimagwiritsidwa ntchito m'malo ovuta kwa nthawi yayitali.
Ponena za kukhazikika kwa kutentha, kulumikizana bwino pakati pa ulusi wopangidwa ndi kaboni ndi zinthu za matrix kungathandize kukhazikika kwa kutentha kwa zinthu zopangidwa ndi kaboni. Pansi pa kutentha kwambiri, zinthu zopangidwa ndi kaboni zimatha kusunga mawonekedwe abwino a makina ndi kukhazikika kwa miyeso, ndipo sizitha kusinthika kapena kuwonongeka kwambiri. Izi zimapangitsa kuti zinthu zopangidwa ndi ulusi wopangidwa ndi kaboni zikhale ndi mwayi waukulu wogwiritsidwa ntchito pakugwiritsa ntchito kutentha kwambiri, monga zida zamagalimoto ndi zida zotentha zamainjini a ndege.
Ponena za magwiridwe antchito a processing, ulusi wa carbon wopangidwa ndi activated umawonjezera ntchito pamwamba ndipo umagwirizana bwino ndi zinthu za matrix. Izi zimapangitsa kuti zinthu za matrix zikhale zosavuta kulowa ndikuchira pamwamba pa ulusi wa carbon panthawi yokonzekera zinthu zophatikizika, motero zimathandizira kukonza bwino komanso mtundu wa zinthuzo. Nthawi yomweyo, kapangidwe ka zinthu zophatikizika za carbon fiber zophatikizika kamakulanso, zomwe zimapangitsa kuti zikhale zosinthika kuti zigwiritsidwe ntchito mosiyanasiyana komanso kukwaniritsa zofunikira zosiyanasiyana zaukadaulo.
Chifukwa chake, chithandizo cha kuyambitsa kwaulusi wa kabonindi njira yofunika kwambiri yokonzekera zinthu zopangidwa ndi ulusi wa kaboni zomwe zimagwira ntchito bwino kwambiri. Kudzera mu njira yogwirira ntchito, kapangidwe ka pamwamba pa ulusi wa kaboni kakhoza kukonzedwa kuti kawonjezere kuuma kwa pamwamba, kuyambitsa magulu ogwira ntchito, ndikuwonjezera mphamvu ya pamwamba, kuti pakhale mphamvu yolumikizirana pakati pa ulusi wa kaboni ndi zinthu za matrix, ndikuyika maziko okonzekera zinthu zopangidwa ndi ulusi wa kaboni zomwe zili ndi mphamvu zabwino kwambiri zamakaniko, kukana dzimbiri, kukhazikika kwa kutentha komanso magwiridwe antchito opangira. Ndi kupita patsogolo kosalekeza kwa sayansi ndi ukadaulo, akukhulupirira kuti ukadaulo wogwirira ntchito ulusi wa kaboni upitiliza kupanga zatsopano ndikukula, kupereka chithandizo champhamvu pakugwiritsa ntchito kwambiri zinthu zopangidwa ndi ulusi wa kaboni.
