Ho utloisisa li-Composites tsa CFRP

- Bokhoni bo Hlollang ba Carbon Fiber e Matlafalitsoeng ke Polymers.

Fiber ea CarbonReinforced Polymer Composites (CFRP) ke lisebelisoa tse bobebe, tse matla tse sebelisoang ho etsa lihlahisoa tse ngata tse sebelisoang bophelong ba rona ba letsatsi le letsatsi. Ke lentsoe le sebelisoang ho hlalosa fiber-reinforcedlintho tse entsoeng ka motsoakoe sebelisang carbon fiber e le karolo ea mantlha ea sebopeho. Re lokela ho hlokomela hore "P" ho CFRP e ka boela ea emela "polasetiki" sebakeng sa "polymer."

Ka kakaretso, metsoako ea CFRP e sebelisa li-resin tsa thermosetting tse kang epoxy,polyester, kapa vinyl ester. Leha ho le joaloli-resin tsa thermoplasticli sebelisoa ho CFRP Composites, "Carbon Fiber Reinforced Thermoplastic Composites" hangata e tsamaea ka mantsoe a eona a khutsufalitsoeng, likarolo tsa CFRTP.

Ha u sebetsa le li-composite kapa ka har'a indasteri ea metsoako, ho bohlokoa ho utloisisa mantsoe le li-acronyms. Habohlokoa le ho feta, hoa hlokahala ho utloisisathepa ea metsoako ea FRPle bokhoni ba li-reinforcements tse fapaneng tse kang carbon fiber.

Thepa ea CFRP Composites

Lisebelisoa tse kopantsoeng, tse matlafalitsoeng ka carbon fiber, li fapane le tse ling tsa FRP tse sebelisang lisebelisoa tsa setso tse kang fiberglass kapafiber ea aramid. Thepa ea li-composites tsa CFRP tse molemo li kenyelletsa:

Boima ba 'mele:Ea setsofiberglass matlafatsoa motsoakoho sebelisa fiber ea khalase e tsoelang pele e nang le fiber ea 70% ea khalase (boima ba khalase / boima bohle), hangata e tla ba le boima ba lik'hilograma tse .065 ka inch cubic.

Ho sa le joalo, motsoako oa CFRP, o nang le boima bo tšoanang ba 70% ba faeba, ka tloaelo o ka ba le boima ba lik'hilograma tse .055 ka cubic inch.

Matla a Eketsehileng:Ha se feela hore lik'hemik'hale tsa carbon fiber li boima bo bobebe, empa metsoako ea CFRP e matla haholo 'me e tiea ho yuniti ea boima ba 'mele. Sena ke 'nete ha ho bapisoa metsoako ea carbon fiber le fiber ea khalase, empa ho feta moo ha e bapisoa le tšepe.

Ka mohlala, molao o motle oa monoana ha o bapisa tšepe le metsoako ea CFRP ke hore sebopeho sa carbon fiber sa matla a lekanang hangata se tla ba boima ba 1/5 ea tšepe. U ka inahanela hore na ke hobane'ng ha lik'hamphani tsa likoloi li etsa lipatlisiso ka ho sebelisa carbon fiber ho e-na le tšepe.

Ha ho bapisoa metsoako ea CFRP le aluminium, e leng e 'ngoe ea litšepe tse bobebe ka ho fetesisa tse sebelisitsoeng, ho nahanoa hore sebopeho sa aluminium se nang le matla a lekanang se ka ba boima ba makhetlo a 1.5 ho feta sebopeho sa carbon fiber.

Ha e le hantle, ho na le mefuta e mengata e fapaneng e ka fetolang papiso ena. Kereiti le boleng ba thepa e ka ba e fapaneng, 'me ka li-composites, lits'ebetso ea tlhahiso, meralo ea likhoele, le boleng bo tlamehang ho eloa hloko.

Mathata a CFRP Composites

Litšenyehelo:Leha e le lisebelisoa tse makatsang, ho na le lebaka leo ka lona carbon fiber e sa sebelisoeng ts'ebetsong e 'ngoe le e' ngoe. Hajoale, likarolo tsa CFRP li na le litšenyehelo tse ngata maemong a mangata. Ho ipapisitsoe le maemo a hajoale a 'maraka (phepelo le tlhokeho), mofuta oa fiber ea carbon (sefofane sa sefofane khahlanong le boemo ba khoebo), le boholo ba fiber tow, theko ea carbon fiber e ka fapana haholo.

Fiber e tala ea k'habone ka theko ea ponto ka 'ngoe e ka ba kae kapa kae pakeng tsa makhetlo a 5 ho isa ho a 25-makhetlo a phahameng ho feta fiberglass. Phapang ena e kholo le ho feta ha ho bapisoa tšepe le metsoako ea CFRP.

Conductivity:Sena se ka ba molemo ho li-composites tsa carbon fiber, kapa bothata ho latela ts'ebeliso. Fiber ea carbon e sebetsa haholo, ha fiber ea khalase e thibela mocheso. Tse ngataLisebelisoa li sebelisa fiber ea khalase, 'me ha e khone ho sebelisa carbon fiber kapa tšepe, ka lebaka la conductivity.

Ka mohlala, indastering ea lisebelisoa, lihlahisoa tse ngata li hlokeha ho sebelisa likhoele tsa khalase. Hape ke le leng la mabaka a etsang hore litepisi li sebelise fiber ea khalase joalo ka liporo tsa lere. Haeba lere la fiberglass le ne le ka kopana le mohala oa motlakase, menyetla ea motlakase e fokotsehile haholo. Ho ke ke ha e-ba joalo ka lere ea CFRP.

Le hoja litšenyehelo tsa metsoako ea CFRP li ntse li le holimo, tsoelo-pele e ncha ea theknoloji tlhahisong e ntse e tsoela pele ho lumella lihlahisoa tse bolokang chelete e ngata. Re tšepa hore bophelong ba rona, re tla khona ho bona fiber ea carbon e theko e tlaase e sebelisoang mefuteng e mengata ea lisebelisoa tsa bareki, tsa indasteri le tsa likoloi.
