Lisebelisoa tsa Carbon Fiber: Tataiso ea Ts'ebetso
Ho etsa li-composite tsa carbon fiber (CF) ke khoebo e qhekellang, ha ho nahanoa hore baenjiniere ba bangata ba nahanang ho hlahisa kapa ho rala ba tsoa morao-rao oa ho rala likarolo tsa tšepe.e ’nile ea bitsoa aluminium e ntšo, ’me moralo oa eona le ho qaptjoa ha eona ho ’nile ha hlalosoa e le bonono ba batho ba batšo.Ke eng, hantle-ntle?
Sepheo sa tataiso ena ea moralo ke ho fana ka tlhahisoleseding e akaretsang le litlhaloso mabapi le lisebelisoa tsa motsoako oa carbon faeba le litataiso tse ling bakeng sa ho rala lihlahisoa tse bobebe tse sebetsang hantle tse nang le metsoako ea carbon faeba.
Hobaneng ha Carbon Fiber
Li-composite tsa carbon fiber li na le lisebelisoa tse ikhethang ha li bapisoa le litšepe tse tšoanang le lipolasetiki.Thepa e matla, e thata, ebile e bobebe.Likarolo tsena ke lisebelisoa tsa khetho bakeng sa lits'ebetso moo ts'ebetso e bobebe le e phahameng e leng ea bohlokoa, joalo ka likarolo tsa sepakapaka, lifofane tsa ntoa le likoloi tsa mabelo.
Carbon Fiber Composites ke eng
Lisebelisoa tse entsoeng ka motsoako li entsoe ka ho kopanya matlafatso (fiber) le matrix (resin), 'me motsoako ona oa fiber le matrix o fana ka litšobotsi tse phahameng ho feta leha e le efe ea thepa feela.Ka thepa e nang le motsoako, fiber e jara boholo ba mojaro 'me ke eona e kenyang letsoho haholo thepa ea thepa.Resin e thusa ho fetisa mojaro lipakeng tsa likhoele, e thibela likhoele ho thella, 'me e kopanya lisebelisoa.
E bitsa bokae?
Histori, metsoako ea carbon fiber e bile theko e boima haholo, e lekanyelitseng tšebeliso ea eona ho likopo tse khethehileng feela.Leha ho le joalo, lilemong tse leshome le metso e supileng tse fetileng, ha tšebeliso e ntse e eketseha le boiketsetso lits'ebetsong tsa tlhahiso bo eketsehile, theko ea lik'hemik'hale tsa carbon fiber e theohile.Phello e kopantsoeng e theotse litšenyehelo tse akaretsang tsa lihlahisoa tse phahameng tsa aluminium.Kajeno, lik'hemik'hale tsa carbon fiber li sebetsa moruong lits'ebetsong tse ngata tse kang thepa ea lipapali, liketsoana tse sebetsang hantle, likoloi tse sebetsang hantle, le mechine e sebetsang hantle ea indasteri.
Lisebelisoa
Lisebelisoa tse kopantsoeng li fapane haholo.Moenjineri a ka khetha ho tsoa mefuteng e mengata e fapaneng ea likhoele le li-resin ho fumana thepa e lakatsehang.Hape, botenya ba thepa le libopeho tsa fiber li ka ntlafatsoa bakeng sa ts'ebeliso ka 'ngoe.
Melemo ea metsoako ea carbon fiber ke:
1.Bothata bo itseng bo phahameng (ho satalla ho arotsoe ka boima ba 'mele)
2.Matla a khethehileng a phahameng (matla a arotsoe ka bongata)
3. Coefficient e tlase haholo ea katoloso ea mocheso (CTE)
4.X-ray e bonaletsang (ka lebaka la boima ba eona bo tlase ba molek'hule)
Ke litšebeliso life tseo metsoako ea carbon fiber e sebelisoang?
Boemo bo ikhethang ba metsoako ea carbon fiber e nang le matla a phahameng a khethehileng, ho satalla, le CTE e tlaase e ba fa sebaka se ikhethang libakeng tse ngata tsa kopo joalokaha ho bontšitsoe tafoleng e ka tlaase:
Lisebelisoa tse tloaelehileng tsa li-composites tsa carbon fiber
Tlhahisoleseding ea Moqapi
Li-composite tsa Carbon Fiber li nkuoa e le "lisebelisoa tsa moqapi" hobane likarolo li ka hlophisoa hore li be le matla le kapa ho satalla litseleng le libaka tse hlokahalang.Sena se finyelloa ka ho beha lisebelisoa ka mokhoa o hlophisitsoeng le tataiso ea fiber ho lumellana hantle le litlhoko.Hape, moralo le phetoho ea tlhahiso eo likarolo tsa carbon fiber li fanang ka eona e fana ka menyetla ea ho ntlafatsa moralo, joalo ka ho kopanya le ho kenyelletsa likarolo tse ngata in-situ, ho fokotsa theko ea karolo kaofela.
Lisebelisoa
Hlobo e sebelisoa ho hlalosa sebōpeho sa likarolo tse entsoeng ka motsoako.Karolo e kopantsoeng e tla nka libopeho tsohle le likarolo tsa hlobo;ka hona boleng ba karolo bo susumetsoa haholo ke boleng ba hlobo.Mefuta e ka ba e tona kapa e tšehali.Mefuta e tšehali ke eona e tloaelehileng haholo 'me e tla hlahisa karolo e nang le bokantle bo boreleli ha hlobo e tona e tla hlahisa bokahare bo boreleli.Ho hlokahala hlobo e ts'oanang (e tona le e tšehali) haeba karolo e kopantsoe ka mochine oa khatiso.
Lisebelisoa tsa likarolo tse peli, tse atisang ho bitsoa "clamshell"
Mefuta e ka etsoa ka lisebelisoa tse kopantsoeng, epoxy e tletseng tšepe kapa e entsoe ka aluminium kapa tšepe.Mofuta oa hlobo le lisebelisoa tse sebelisoang li itšetlehile ka mofuta oa karolo le bongata ba tlhahiso.
Mokhoa oa Tlhahiso
Tlhahiso e tsoetseng pele ea khabone hangata e etsoa ho sebelisoa fiber ea carbon e kentsoeng pele e nang le li-resin tsa thermoset.Mekhoa e 'meli ea bohlokoa e sebelisoang ke:
1. Ho robala ka matsoho
Ho hlophisoa ka letsoho ha thepa e lohiloeng pele e kenngoe e ntse e le karolo e kholo ea indasteri ea tlhahiso e kopaneng, e hlokang litsebo le boiphihlelo ba basebetsi ba batho ho etsa li-plies tse bataletseng ho ba libopeho tse rarahaneng.E khona ho hlahisa ts'ebetso e phahameng le likarolo tse rarahaneng empa e ka ba ts'ebetso e theko e boima le e fapaneng haholo.
