Carbon fiber, fiber e sebetsang hantle haholo, e na le lintho tse ngata tse qobellang. Haholo-holo e entsoe ka k'habone 'me e na le sebopeho sa filamentary e telele. Ho ea ka pono ea sebopeho sa bokaholimo, bokaholimo ba carbon fiber bo batla bo le boreleli 'me bo na le lihlopha tse fokolang tse sebetsang. Sena se bakoa ke taba ea hore nakong ea ho lokisoa ha carbon fibers, mocheso o phahameng oa carbonization le mekhoa e meng ea phekolo e etsa hore bokaholimo ba likhoele tsa carbon bo be le boemo bo fokolang haholoanyane. Thepa ena e ka holim'a metsi e tlisa letoto la liqholotso ho lokisoeng ha metsoako ea carbon fiber.
Sebaka se boreleli se etsa hore maqhama pakeng tsa carbon fiber le matrix a fokotsehe. Ha ho lokisoa li-composites, ho thata hore thepa ea matrix e thehe maqhama a matla holim'a metsi.carbon fiber, e amang ts'ebetso ea kakaretso ea lisebelisoa tse kopantsoeng. Taba ea bobeli, ho haella ha lihlopha tse sebetsang ho fokotsa karabelo ea lik'hemik'hale lipakeng tsa likhoele tsa khabone le lisebelisoa tsa matrix. Sena se etsa hore maqhama a sefahleho pakeng tsa tse peli haholo-holo a itšetlehe ka liphello tsa 'mele, tse kang ho kenya mochine, joalo-joalo, tseo hangata li sa tsitsang ka ho lekaneng' me li atisa ho arohana ha li tlas'a matla a ka ntle.

E le ho rarolla mathata ana, ho hlokahala hore ho sebelisoe phekolo ea carbon fibers. E kentswelikhoele tsa carbonbontša liphetoho tse kholo likarolong tse 'maloa.
Kalafo ea activation e eketsa bokhabane ba holim'a carbon fibers. Ka oxidation ea lik'hemik'hale, kalafo ea plasma le mekhoa e meng, likoti tse nyane le li-grooves li ka kengoa ka holim'a likhoele tsa khabone, e leng ho etsang hore bokaholimo bo be thata. Sebaka sena se mahoashe se eketsa sebaka sa ho kopana pakeng tsa carbon fiber le thepa ea substrate, e leng ho ntlafatsang maqhama a mechine pakeng tsa tse peli. Ha thepa ea matrix e tlamahane le carbon fiber, e khona ho ikakhela ka setotsoana ka har'a mehaho ena e thata, e etsa tlamo e matla haholoanyane.
Phekolo ea ts'ebetso e ka hlahisa lihlopha tse ngata tse sebetsang tse sebetsang ka holim'a carbon fiber. Lihlopha tsena tse sebetsang li ka sebetsana le lik'hemik'hale le lihlopha tse sebetsang tse tsamaisanang le thepa ea matrix ho etsa lik'hemik'hale tsa lik'hemik'hale. Mohlala, kalafo ea oxidation e ka hlahisa lihlopha tsa hydroxyl, lihlopha tsa carboxyl le lihlopha tse ling tse sebetsang holim'a likhoele tsa carbon, tse ka sebetsanang leepoxylihlopha ka har'a matrix a resin joalo-joalo ho theha maqhama a covalent. Matla a tlamahano ena ea lik'hemik'hale a phahame haholo ho feta a ho tlamahanngoa ha 'mele, e leng ho ntlafatsang haholo matla a ho kopanya sefahleho pakeng tsa carbon fiber le thepa ea matrix.
Matla a holim'a carbon fiber e entsoeng ka carbon e boetse e eketseha haholo. Ho eketseha ha matla a holim'a metsi ho etsa hore ho be bonolo hore carbon fiber e kolobisoe ke lisebelisoa tsa matrix, kahoo e nolofalletse ho ata le ho kenella ha thepa ea matrix holim'a carbon fiber. Ha ho ntse ho etsoa li-composite, thepa ea matrix e ka aroloa ka ho lekana ho pota-potile likhoele tsa carbon ho etsa sebopeho se teteaneng haholoanyane. Sena ha se ntlafatse feela thepa ea mechine ea thepa e kopantsoeng, empa hape e ntlafatsa thepa ea eona e meng, e kang ho hanyetsa kutu le botsitso ba mocheso.
Li-activated carbon fibers li na le melemo e mengata bakeng sa ho lokisa metsoako ea carbon fiber.
Mabapi le thepa ea mechine, matla a ho kopanya lifapano pakeng tsa ts'ebetsolikhoele tsa carbon'me thepa ea matrix e ntlafatsoa haholo, e leng se nolofalletsang li-composites ho fetisa khatello ea kelello hamolemo ha li tlas'a matla a ka ntle. Sena se bolela hore thepa ea mechine ea metsoako e kang matla le modulus e ntlafalitsoe haholo. Ka mohlala, sebakeng sa lifofane, se hlokang lisebelisoa tse phahameng ka ho fetisisa tsa mechine, likarolo tsa lifofane tse entsoeng ka metsoako ea carbon fiber e entsoeng ka activated li khona ho mamella meroalo e meholo ea lifofane le ho ntlafatsa polokeho le botšepehi ba sefofane. Lebaleng la thepa ea lipapali, joalo ka liforeimi tsa libaesekele, litlelapo tsa kolofo, joalo-joalo, li-composite tsa carbon fiber tse kentsoeng li ka fana ka matla a betere le ho satalla, ha li ntse li fokotsa boima ba 'mele le ho ntlafatsa boiphihlelo ba baatlelete.
Mabapi le ho hanyetsa kutu, ka lebaka la ho kenngoa ha lihlopha tse sebetsang tse sebetsang ka holim'a li-carbon fibers, lihlopha tsena tse sebetsang li ka theha maqhama a tsitsitseng a lik'hemik'hale le thepa ea matrix, kahoo e ntlafatsa ho hanyetsa ha li-composites. Maemong a mang a thata a tikoloho, joalo ka tikoloho ea leoatle, indasteri ea lik'hemik'hale, joalo-joalo, e kentsoengmetsoako ea carbon fibere ka hanela ho senyeha ha mecha ea litaba e senyang le ho lelefatsa bophelo ba tšebeletso. Sena ke sa bohlokoa haholo bakeng sa lisebelisoa tse ling le meaho e sebelisoang libakeng tse thata ka nako e telele.
Mabapi le botsitso ba mocheso, tlamahano e ntle ea sefahleho pakeng tsa activated carbon fiber le thepa ea matrix e ka ntlafatsa botsitso ba mocheso oa metsoako. Tlas'a tikoloho ea mocheso o phahameng, li-composites li ka boloka thepa e ntle ea mochine le botsitso ba litekanyo, 'me ha li na monyetla oa ho senyeha le ho senyeha. Sena se etsa hore li-composite tsa carbon fiber li be le tebello e pharaletseng ea ts'ebeliso lits'ebetsong tsa mocheso o phahameng, joalo ka likarolo tsa enjene ea likoloi le likarolo tse chesang tsa enjene ea sefofane.
Mabapi le ts'ebetso ea ts'ebetso, li-activated carbon fibers li ekelitse ts'ebetso ea holim'a metsi le ho lumellana hamolemo le thepa ea matrix. Sena se etsa hore ho be bonolo hore thepa ea matrix e kenelle le ho phekola holim'a carbon fiber nakong ea ho lokisoa ha thepa e entsoeng ka motsoako, kahoo e ntlafatsa ts'ebetso ea ts'ebetso le boleng ba sehlahisoa. Ka nako e ts'oanang, sebopeho sa li-composite tsa k'habone e entsoeng ka fiber e boetse e matlafatsoa, ho li lumella hore li tloaelehe bakeng sa lisebelisoa tse fapaneng le ho finyella litlhoko tse fapaneng tse rarahaneng tsa boenjiniere.
Ka hona, ts'ebetso ea kalafo ealikhoele tsa carbonke sehokelo se ka sehloohong ho lokiseng metsoako ea carbon fiber e sebetsang hantle haholo. Ka ts'ebetso ea ts'ebetso ea ts'ebetso, sebopeho sa holim'a carbon fiber se ka ntlafatsoa ho eketsa boima ba holim'a metsi, ho hlahisa lihlopha tse sebetsang tse sebetsang, le ho ntlafatsa matla a holim'a metsi, e le ho ntlafatsa matla a ho kopanya sefahleho pakeng tsa carbon fiber le matrix, le ho rala motheo. bakeng sa ho lokisa metsoako ea carbon fiber e nang le thepa e babatsehang ea mochine, ho hanyetsa kutu, botsitso ba mocheso le ts'ebetso ea ho sebetsa.
