Njira yothandizira mpweya wa carbon fiber

Tsiku:2022-05-28 Gwero: Fiber Composites Sakatulani: 5204

Mpweya wa carbon uli ndi mphamvu zenizeni zenizeni, modulus yapamwamba kwambiri, kukana kutopa, kukana dzimbiri ndi zinthu zina zabwino kwambiri, zomwe zimagwiritsidwa ntchito kwambiri muzamlengalenga, makampani ankhondo, zida zamasewera ndi zina. Mpweya wa carbon unalimbitsa ma polymerization

Mpweya wa carbon uli ndi mphamvu zenizeni zenizeni, modulus yapamwamba kwambiri, kukana kutopa, kukana dzimbiri ndi zinthu zina zabwino kwambiri, zomwe zimagwiritsidwa ntchito kwambiri muzamlengalenga, makampani ankhondo, zida zamasewera ndi zina. Kapangidwe ka kaboni fiber yolimbitsa ma polymer matrix composites imadalira kwambiri mawonekedwe apakati pa carbon fiber ndi matrix. Komabe, malo osalala a mpweya wa kaboni, kutengeka kwakukulu kwamalingaliro ndi magulu ochepa omwe amagwira ntchito ndi mankhwala amachititsa kuti pakhale mgwirizano wofooka pakati pa carbon fiber ndi matrix resin, ndipo gawo la mawonekedwe nthawi zambiri limakhala lofooka la zipangizo zophatikizika. The interfacial microstructure ya carbon fiber composites imagwirizana kwambiri ndi mawonekedwe apakati. Kuphatikizika kwa mpweya wa carbon fiber pamapeto pake kumakhala pamapangidwe apamwamba a carbon fiber ndi mitundu yamagulu ogwira ntchito zamakhemikolo. Kuwonjezeka kwa magulu ogwira ntchito komanso kuwonjezereka kwa roughness ya carbon fiber pamwamba kumathandizira kuwonjezereka kwa carbon fiber pamwamba mphamvu. Zowoneka bwino za kaboni fiber makamaka zimaphatikizira kapangidwe kapamwamba, kukula ndi kagayidwe ka groove, kuuma kwapamtunda, mphamvu zopanda mphamvu ndi zina zotero. Pankhani ya mawonekedwe a pamwamba, pali pores, grooves, zonyansa ndi makhiristo pamwamba pa carbon fiber, zomwe zimakhudza kwambiri kugwirizana kwa zinthu zophatikizika. The chemical reactivity of carbon fiber surface is closely related to the concentration of active groups, and these active groups are especially oxygen with active groups such as light group, spindle group and epoxy group. Chiwerengero cha zinchito magulu padziko mpweya CHIKWANGWANI zimadalira pamwamba electrochemical mankhwala njira ndi digiri kapena kutentha kwa CHIKWANGWANI carbonization. Mwachitsanzo, chithandizo cha asidi chidzapatsa magulu ogwira ntchito osiyanasiyana kusiyana ndi mankhwala a alkali, ndipo pazikhalidwe zomwezo, kutentha kwa carbonization kumakwera, magulu ochepa ogwira ntchito. Low modulus mpweya CHIKWANGWANI zambiri zinchito magulu chifukwa otsika digiri ya carbonization, choncho amachita ndi epoxy gulu pokonzekera epoxy masanjidwewo nsanganizo, pamene zimene mkulu modulus mpweya CHIKWANGWANI dongosolo akhoza kunyalanyazidwa, ndi CHIKWANGWANI ndi utomoni. makamaka kukhala ndi kuyanjana kofooka. Kafukufuku wambiri wawonetsa kuti mawonekedwe a ma kompositi amatha kuwongolera bwino posintha mawonekedwe a ma composites ophatikizika ndikusintha kwa carbon fiber, yomwe ndi imodzi mwamalo ochita kafukufuku pankhani ya zida za carbon fiber cladding.
