Mochini oa ho loha fiber ea carbonke boemo bo phahameng haholomochini o lohangsehlahisoa sa letoto lena la metjhini e lohang.Ha ho bapisoa le lisebelisoa tsa khale tsa ho loha tse kang khoele ea k'hothone le terata ea tšepe, mochini o lohang oa carbon fiber o na le litlhoko tse phahameng tsa theknoloji le moralo o rarahaneng le ho etsa tlhahiso.
Leha ho le joalo, ho ke ke ha latoloa hore ha ho bapisoa le thepa e lohiloeng ea setso, carbon fiber weaving e na le litšobotsi tse ntle haholo, 'me litebello tsa eona tsa ts'ebeliso ea nako e tlang li pharaletseng.Lena ke le leng la mabaka a entseng hore Benfa Technology esale e etsa theknoloji ea ho loha ha carbon fiber e le tataiso ea bohlokoa ea katleho.
Ha ho bapisoa le thepa e lohiloeng ea setso, litšobotsi tsa thepa ea carbon fiber ke life?
1. Matla a matla a ho tsitsa
Matla a thata a carbon fiber a ka ba 2 ho isa ho 7 GPa, 'me modulus ea tensile e ka ba 200 ho isa ho 700 GPa.Boima ba ligrama tse 1.5 ho isa ho tse 2.0 ka cubic centimeter, eo haholo-holo e khethoang ke mocheso oa mokhoa oa carbonization ho phaella ho sebopeho sa silika ea pele.Ka kakaretso ka mor'a phekolo ea graphitization ea mocheso o phahameng oa 3000 ℃, boima bo ka fihla ho 2.0 dikgerama ka centimeter e le 'ngoe.Ho phaella moo, boima ba eona bo bobebe haholo, matla a eona a khoheli a khethehileng a bobebe ho feta aluminium, a ka tlaase ho 1/4 ea tšepe, 'me matla a eona a khethehileng ke makhetlo a 20 a tšepe.Mocheso oa ho eketsa mocheso oa carbon fiber o fapane le likhoele tse ling, 'me o na le litšobotsi tsa anisotropy.
2. Coefficient e nyenyane ea ho atolosa mocheso
Mocheso oa katoloso ea boholo ba fiber ea carbon ka boeona e mpe ka tlung (-0.5~-1.6)×10-6/K, ke zero ho 200-400 ℃, le 1.5×10-6/K ha e le ka tlase ho 1000 ℃ .Thepa e kopantsoeng e entsoeng ka eona e na le coefficient e batlang e tsitsitse ea ho atolosa 'me e ka sebelisoa e le sesebelisoa sa ho bekha se tloaelehileng.
3. Molemo o motle oa ho futhumatsa mocheso
Ka kakaretso, conductivity ea mocheso oa thepa ea tlhaho le ea tlhaho e fokola, empa mocheso oa mocheso oa carbon fiber o haufi le oa tšepe.Ho sebelisa monyetla ona, e ka sebelisoa e le lisebelisoa bakeng sa babokelli ba mocheso oa letsatsi le lisebelisoa tsa khetla tse tsamaisang mocheso tse nang le mocheso o ts'oanang oa mocheso.
4. E bonolo ebile e sebetsa
Ntle le litšoaneleho tsa lisebelisoa tsa khabone ka kakaretso, masela a lohiloeng ka carbon fiber a na le ponahalo e bonolo ea anisotropic mme a ka sebetsoa ka masela a fapaneng.Ka lebaka la matla a bona a khoheli a manyane, li bonts'a matla a phahameng haufi le axis ea fiber.Li-rings tse matlafalitsoeng ka fiber ea carbon Lisebelisuoa tse kopantsoeng tsa resin ea oksijene li na le matšoao a phahameng ka ho fetesisa a matla a ikhethileng le modulus e ikhethang har'a lisebelisoa tse teng tsa meralo.
5. Ho hanyetsa mocheso o tlaase
Carbon fiber e na le khanyetso e ntle ea mocheso o tlase, joalo ka ha e senyehe tlas'a mocheso oa metsi oa naetrojene.
6. Ho hanyetsa kutu
Fiber ea carbon e na le khanyetso e ntle ea kutu ho li-solvents, acid le alkalis.Ha e qhibilihe kapa hona ho ruruha.E na le khanyetso e ikhethang ea corrosion mme ha e na bothata ba mafome.
7. Ho hanyetsa ho apara hantle
Fiber ea carbon le tšepe ha li aparoe ka seoelo ha li hohlana.Fiber ea carbon e sebelisoa ho nkela asbestos sebaka ho etsa lisebelisoa tsa boemo bo holimo tse hohlang, tse 'nileng tsa sebelisoa e le lisebelisoa tsa mariki bakeng sa lifofane le likoloi.
8. Ho hanyetsa mocheso o phahameng o motle
Ts'ebetso ea carbon fiber e tsitsitse haholo ka tlase ho 400 ° C, 'me ha ho na phetoho e ngata esita le ho 1000 ° C.Ho hanyetsa mocheso o phahameng oa lisebelisoa tse kopantsoeng haholo-holo ho itšetlehile ka ho hanyetsa mocheso oa matrix.Ho hanyetsa mocheso oa nako e telele oa lisebelisoa tse entsoeng ka resin e ka bang 300 ℃ feela, 'me mocheso o phahameng oa mocheso oa lisebelisoa tse entsoeng ka ceramic, carbon-based le tšepe li ka tsamaisana le carbon fiber ka boeona.Lisebelisoa tsa motsoako oa carbon fiber li sebelisoa haholo indastering ea sefofane e le lisebelisoa tse hanyetsanang le mocheso o phahameng.
9. Bokhabane bo babatsehang
Fiber ea carbon e na le bokhabane bo botle haholo (e 'ngoe ea lipontšo tsa botle ke palo ea ligrama tsa fiber e bolelele ba limithara tse 9000), ka kakaretso e ka ba ligrama tse 19 feela, le matla a matla a fihlang ho 300 kg micron ka 'ngoe.Lisebelisoa tse ling tse seng kae li na le litšobotsi tse ngata tse ntle joaloka carbon fiber.
10. Ho hanyetsa tšusumetso e mpe le ho senya habonolo
Oxidation e etsahala tlas'a ketso ea asiti e matla, matla a electromotive a carbon fiber a ntle, 'me matla a electromotive a alloy alloy a fosahetse.Ha lisebelisoa tsa carbon fiber composite li sebelisoa hammoho le lisebelisoa tsa aluminium, carbonization ea tšepe, carburization le electrochemical corrosion e tla etsahala.Ka hona, fiber ea carbon e tlameha ho phekoloa ka holimo pele e sebelisoa.
