M'nthawi yamasiku ano ya kupita patsogolo kwaukadaulo, ma carbon fiber composites akudzipangira dzina m'magawo osiyanasiyana chifukwa chakuchita bwino kwambiri. Kuchokera pamagwiritsidwe apamwamba kwambiri muzamlengalenga kupita ku zosowa za tsiku ndi tsiku zamasewera, ma carbon fiber composites awonetsa kuthekera kwakukulu. Komabe, kukonzekera mkulu-ntchito carbon CHIKWANGWANI composites, kutsegula chithandizo chacarbon fiberndi sitepe yofunika kwambiri.
Chithunzi cha kaboni fiber pamwamba electron maikulosikopu
Mpweya wa carbon, ulusi wochita bwino kwambiri, uli ndi zinthu zambiri zokakamiza. Amapangidwa makamaka ndi kaboni ndipo ali ndi mawonekedwe otalikirapo a filamentary. Kuchokera pamawonekedwe a pamwamba, pamwamba pa carbon fiber ndi yosalala ndipo imakhala ndi magulu ochepa ogwira ntchito. Izi ndichifukwa choti panthawi yokonza ma fiber a carbon, kutentha kwapamwamba kwambiri kwa carbonization ndi mankhwala ena kumapangitsa kuti pamwamba pa carbon fibers ikhale yowonjezereka. Katundu wapamtunda uwu umabweretsa zovuta zingapo pakukonzekera ma composites a carbon fiber.
Malo osalala amapangitsa kuti mgwirizano wa carbon fiber ndi matrix ukhale wofooka. Pokonzekera ma composites, zimakhala zovuta kuti zinthu za matrix zikhale zomangira zolimba pamwamba pacarbon fiber, zomwe zimakhudza ntchito yonse ya zinthu zophatikizika. Kachiwiri, kusowa kwa magulu ogwira ntchito kumachepetsa zomwe zimachitika pakati pa ma carbon fiber ndi matrix. Izi zimapangitsa mgwirizano wapakati pakati pa awiriwo makamaka kudalira zotsatira za thupi, monga kuyika makina, ndi zina zotero, zomwe nthawi zambiri zimakhala zosakhazikika mokwanira ndipo zimakhala zosavuta kupatukana pamene zimagonjetsedwa ndi mphamvu zakunja.
Chithunzi chojambula cha interlayer kulimbikitsa nsalu za carbon fiber ndi carbon nanotubes
Kuti athetse mavutowa, kuyambitsa chithandizo cha carbon fibers kumakhala kofunikira. Adayatsidwacarbon fiberwonetsani kusintha kwakukulu muzinthu zingapo.
Chithandizo cha activation chimawonjezera kuuma kwa ma carbon fibers. Kupyolera mu makutidwe ndi okosijeni wamankhwala, mankhwala a plasma ndi njira zina, maenje ang'onoang'ono ndi ma grooves amatha kukhazikika pamwamba pa ulusi wa kaboni, kupangitsa kuti pamwamba pakhale nkhanza. Izi akhakula pamwamba kumawonjezera kukhudzana dera pakati mpweya CHIKWANGWANI ndi gawo lapansi zakuthupi, amene bwino mawotchi chomangira pakati pa awiriwo. Zinthu za matrix zikalumikizidwa ndi mpweya wa kaboni, zimatha kudziyika zokha muzomangamanga izi, ndikupanga mgwirizano wamphamvu.
Chithandizo cha activation chikhoza kuyambitsa magulu ambiri ogwira ntchito pamtunda wa carbon fiber. Magulu ogwira ntchitowa amatha kuchitapo kanthu ndi magulu ofananirako muzinthu zamatrix kuti apange ma chemical bonds. Mwachitsanzo, chithandizo cha okosijeni chimatha kuyambitsa magulu a hydroxyl, magulu a carboxyl ndi magulu ena ogwira ntchito pamtunda wa carbon fibers, omwe amatha kuchitapo kanthu ndiepoxymagulu mu utomoni matrix ndi zina zotero kupanga covalent zomangira. Kulimba kwa mgwirizano wamankhwala uku ndikokwera kwambiri kuposa kulumikizana kwakuthupi, komwe kumawongolera kwambiri mphamvu yolumikizana pakati pa kaboni fiber ndi matrix.
Mphamvu yapamtunda ya activated carbon fiber imakulanso kwambiri. Kuwonjezeka kwa mphamvu ya pamwamba kumapangitsa kuti mpweya wa kaboni ukhale wosavuta kuti unyowedwe ndi zinthu za matrix, motero kumathandizira kufalikira ndi kulowa kwa matrix pamwamba pa carbon fiber. Pokonzekera ma composites, matrix amatha kugawidwa mofanana mozungulira ma fiber kuti apange mawonekedwe owundana kwambiri. Izi sizimangowonjezera mphamvu zamakina azinthu zophatikizika, komanso zimathandizira zina zake, monga kukana kwa dzimbiri komanso kukhazikika kwamafuta.
Ma kaboni opangidwa ndi kaboni ali ndi maubwino angapo pokonzekera ma composites a carbon fiber.
Pankhani ya makina katundu, interfacial kugwirizana mphamvu pakati adamulowetsacarbon fiberndipo zinthu za matrix zimakhala bwino kwambiri, zomwe zimathandiza kuti ma composites athe kusamutsa bwino kupsinjika akamakhudzidwa ndi mphamvu zakunja. Izi zikutanthauza kuti zida zamakina a kompositi monga mphamvu ndi modulus zimakhala bwino kwambiri. Mwachitsanzo, m'gawo lazamlengalenga, lomwe limafunikira zida zamakina apamwamba kwambiri, zida za ndege zopangidwa ndi zida za carbon fiber zimatha kupirira kunyamula katundu wambiri ndikuwongolera chitetezo ndi kudalirika kwa ndege. Pankhani ya zinthu zamasewera, monga mafelemu a njinga, makalabu a gofu, ndi zina zotere, zophatikizika za carbon fiber zimatha kupereka mphamvu komanso kuuma mtima, kwinaku zimachepetsa kulemera komanso kuwongolera luso la othamanga.
Pankhani ya kukana kwa dzimbiri, chifukwa cha kukhazikitsidwa kwa magulu ogwira ntchito okhazikika pamwamba pa makina opangidwa ndi kaboni, magulu ogwira ntchitowa amatha kupanga mgwirizano wokhazikika wamankhwala ndi zinthu za matrix, motero kuwongolera kukana kwa dzimbiri kwa zophatikizika. Nthawi zina zovuta zachilengedwe, monga chilengedwe m'madzi, makampani mankhwala, etc., ndi adamulowetsakaboni fiber kompositiamatha kukana kukokoloka kwa media zowononga ndikukulitsa moyo wautumiki. Izi ndizofunikira kwambiri pazida ndi zida zina zomwe zimagwiritsidwa ntchito m'malo ovuta kwa nthawi yayitali.
Pankhani ya kukhazikika kwamafuta, kulumikizana kwabwino kwapakati pakati pa activated carbon fiber ndi matrix zinthu kumatha kupangitsa kukhazikika kwamafuta amitundu. Pansi pa kutentha kwapamwamba, zophatikizika zimatha kukhala ndi zida zabwino zamakina komanso kukhazikika kwapakatikati, ndipo sizimawonongeka komanso kuwonongeka. Izi zimapangitsa kuti makina opangidwa ndi kaboni fiber akhale ndi mwayi wogwiritsa ntchito kwambiri pakutentha kwambiri, monga magawo a injini zamagalimoto ndi magawo otentha a injini ya ndege.
Pankhani yakukonza magwiridwe antchito, ma fiber opangidwa ndi kaboni achulukitsa zochitika zapamtunda komanso kugwirizanitsa bwino ndi matrix. Izi zimapangitsa kuti zinthu za matrix zikhale zosavuta kulowa ndikuchiritsa pamwamba pa kaboni fiber panthawi yokonza zinthu zophatikizika, motero kumapangitsa kuti ntchitoyo ikhale yabwino komanso mtundu wazinthu. Panthawi imodzimodziyo, kupangika kwa makina opangidwa ndi carbon fiber composites kumakulitsidwanso, kuwalola kuti azisinthidwa kuti azigwiritsidwa ntchito zosiyanasiyana ndikukwaniritsa zofunikira zosiyanasiyana zaumisiri.
Choncho kutsegula mankhwala acarbon fiberndiye ulalo wofunikira kwambiri pokonzekera zida za carbon fiber composites zogwira ntchito kwambiri. Kudzera mu activation mankhwala, kapangidwe padziko mpweya CHIKWANGWANI akhoza bwino kuonjezera roughness pamwamba, kuyambitsa magulu zinchito yogwira, ndi kusintha mphamvu pamwamba, kuti patsogolo interfacial chomangira mphamvu pakati mpweya CHIKWANGWANI ndi masanjidwewo zakuthupi, ndi kuyala maziko. pokonzekera ma composites a carbon fiber okhala ndi makina abwino kwambiri, kukana kwa dzimbiri, kukhazikika kwamafuta ndi magwiridwe antchito. Ndi kupita patsogolo kosalekeza kwa sayansi ndi ukadaulo, akukhulupirira kuti ukadaulo wa carbon fiber activation upitiliza kupanga zatsopano, ndikupereka chithandizo champhamvu pakugwiritsa ntchito zida zambiri za carbon fiber.
