Har'a lisebelisoa tse ngata, li-composites tsa carbon fiber (CFRP) li lebisitsoe tlhokomelo e eketsehileng bakeng sa matla a tsona a ikhethang, ho satalla ho itseng, ho hanyetsa kutu, le ho hanyetsa mokhathala.
Litšobotsi tse fapaneng lipakeng tsa li-composite tsa carbon fiber le lisebelisoa tsa tšepe le tsona li fa baenjiniere mehopolo e fapaneng ea moralo.
Se latelang e tla ba papiso e bonolo pakeng tsa metsoako ea carbon fiber le litšobotsi tsa tšepe tsa setso le phapang.
1. Ho satalla ho itseng le matla a itseng
Ha ho bapisoa le lisebelisoa tsa tšepe, lisebelisoa tsa carbon fiber li na le boima bo bobebe, matla a khethehileng a phahameng, le ho satalla ho itseng.Modulus ea resin-based carbon fiber e phahame ho feta ea aluminium alloy, 'me matla a carbon fiber e thehiloeng ho resin a phahame haholo ho feta a alloy alloy.
2. Boqapi
Lisebelisoa tsa tšepe hangata li na le bong bo ts'oanang, ho na le lihlahisoa kapa lihlahisoa tse nang le maemo.'Me fiber ea carbon e le 'ngoe e na le directivity e hlakileng.
Thepa ea mochini ho latela tataiso ea fiber e 1 ~ 2 ka liodara tsa boholo bo holimo ho feta tse haufi le terata e otlolohileng le thepa ea ho kuta e bolelele le e hlabang, 'me li-curve tsa khatello ea maikutlo li mela ka mela pele ho robeha.
Ka hona, thepa ea carbon fiber e ka khetha angle ea ho beha, tekanyo ea ho beha, le tatellano ea ho behoa ha lera le le leng ka khopolo ea poleiti ea lamination.Ho ea ka litšoaneleho tsa kabo ea mojaro, ho satalla le ts'ebetso ea matla ho ka fumanoa ka moralo, ha lisebelisoa tsa tšepe tsa setso li ka teteaneng feela.
Ka nako e ts'oanang, boima bo hlokahalang ka sefofaneng le matla hammoho le boits'oaro bo ikhethang ba ho kopanya ka sefofaneng le ka ntle ho sefofane bo ka fumanoa.
3. Ho hanyetsa kutu
Ha ho bapisoa le lisebelisoa tsa tšepe, lisebelisoa tsa carbon fiber li na le acid e matla le khanyetso ea alkali.Carbon fiber ke sebopeho sa microcrystalline se ts'oanang le kristale ea graphite e entsoeng ke graphitization ka mocheso o phahameng oa 2000-3000 ° C, e hanyetsanang haholo le kutu e mahareng, ho fihlela ho 50% hydrochloric acid, sulfuric acid kapa phosphoric acid, modulus elastic, matla, le bophara lula ha e le hantle e sa fetohe.
Ka hona, e le thepa e matlafatsang, carbon fiber e na le tiisetso e lekaneng ea ho hanyetsa kutu, resin e fapaneng ea matrix e hanyetsanang le kutu e fapane.
Joaloka epoxy e tloaelehileng ea carbon fiber-reinforced epoxy, epoxy e na le khanyetso e ntle ea leholimo 'me e ntse e boloka matla a eona hantle.
4. Anti Fatigue
Khatello ea khatello le boemo bo phahameng ba khatello ke lintlha tse ka sehloohong tse susumetsang thepa ea mokhathala oa metsoako ea carbon fiber.Lintho tsa mokhathala li atisa ho behoa litekong tsa mokhathala tlas'a khatello (R = 10) le khatello e matla (r = -1), ha lisebelisoa tsa tšepe li lekoa ka liteko tsa mokhathala tlas'a khatello (R = 0.1).Ha ho bapisoa le likarolo tsa tšepe, haholo-holo likarolo tsa aluminium alloy, likarolo tsa carbon fiber li na le thepa e ntle ea mokhathala.Lefapheng la chassis ea likoloi joalo-joalo, li-composite tsa carbon fiber li na le melemo e metle ea ts'ebeliso.Ka nako e ts'oanang, ho na le hoo e ka bang ha ho na phello ea "notch" carbon fiber.Mokokotlo oa SN oa teko ea notched o tšoana le oa teko e sa tsitsang bophelong bohle ba boholo ba carbon fiber laminates.
5. Ho hlaphoheloa
Hajoale, carbon fiber matrix e butsoitseng e entsoe ka resin ea thermosetting, eo ho leng thata ho ntšoa le ho sebelisoa hape ka mor'a ho phekola le ho hokahanya.Ka hona, bothata ba ho hlaphoheloa ha carbon fiber ke e 'ngoe ea litšitiso tsa tsoelo-pele ea indasteri, hape ke bothata ba theknoloji bo lokelang ho rarolloa ka potlako bakeng sa kopo e kholo.Hona joale, mekhoa e mengata ea ho tsosolosa lapeng le linaheng tse ling e na le litšenyehelo tse phahameng 'me ho thata ho etsoa indastering.Walter carbon fiber e hlahloba ka mafolofolo litharollo tse ka sebelisoang hape, e phethile mehlala e mengata ea tlhahiso ea liteko, phello ea ho hlaphoheloa e ntle, ka maemo a tlhahiso ea boima.
Qetello
Ha ho bapisoa le lisebelisoa tsa tšepe tse tloaelehileng, lisebelisoa tsa carbon fiber li na le melemo e ikhethang ho thepa ea mochine, e bobebe, e nang le bokhoni le ho hanyetsa mokhathala.Leha ho le joalo, katleho ea eona ea tlhahiso le ho hlaphoheloa ka thata e ntse e le litšitiso tsa ts'ebeliso ea eona e eketsehileng.Ho lumeloa hore carbon fiber e tla sebelisoa haholoanyane le ho feta hammoho le ncha ea theknoloji le ts'ebetso.
