Carbon fiber braiding muchinandeyepamusoro-sorokurukwa muchinachigadzirwa cheiyi nhevedzano yemichina yekuruka.Zvichienzaniswa neyechinyakare zvekuruka zvinhu zvakaita seshinda yedonje uye waya yesimbi, kabhoni fibre yekuruka muchina ine yakakwirira tekinoroji zvinodiwa uye yakanyanya kuoma dhizaini nekugadzira.
Nekudaro, hazvirambike kuti kana zvichienzaniswa neyakarukwa zvinhu zvechinyakare, kabhoni faibha kuruka zvine hunhu hwakanaka, uye tarisiro yayo yekushandisa mune ramangwana yakakura.Ichi ndicho chimwe chezvikonzero nei Benfa Technology yagara ichiita kabhoni fiber weaving tekinoroji nzira yakakosha yekufambisa.
Kuenzaniswa nemidziyo yakarukwa yechinyakare, ndeapi maitiro ecarbon fiber zvinhu?
1. Kusimba kwakasimba
Simba rekusimba rekabhoni fiber rinenge 2 kusvika 7 GPa, uye tensile modulus inenge mazana maviri kusvika 700 GPa.Density inenge 1.5 kusvika 2.0 magiramu pa cubic centimita, iyo inonyanya kutariswa nekupisa kweiyo carbonization process mukuwedzera kune chimiro chesirika yepakutanga.Kazhinji mushure mekupisa kwakanyanya 3000 ℃ graphitization kurapwa, density inogona kusvika 2.0 magiramu pacubic centimita.Pamusoro pezvo, uremu hwayo hwakareruka kwazvo, giravhiti rayo rakareruka kupfuura aruminiyamu, isingasviki 1/4 yesimbi, uye simba rayo chairo rakapetwa ka20 pane resimbi.Iyo yekupisa yekuwedzera coefficient yekabhoni fiber yakasiyana nedzimwe fiber, uye ine maitiro eanisotropy.
2. Diki rekuwedzera kwemafuta coefficient
Thermal yekuwedzera coefficient yeakawanda kabhoni fiber pachayo haina kunaka mukati (-0.5~-1.6) × 10-6/K, iri zero pa200-400 ℃, uye 1.5 × 10-6/K kana iri pasi pe1000 ℃ .Iyo inoumbwa zvinhu yakagadzirwa nayo ine yakagadzikana yekuwedzera coefficient uye inogona kushandiswa seyakajairwa kuyera chiridzwa.
3. Good thermal conductivity
Kazhinji, kupisa kwemafuta ezvinyorwa uye organic zvinhu hazvina kunaka, asi kupisa kwekabhoni fiber kuri pedyo nesimbi.Kutora mukana weiyi mukana, inogona kushandiswa sechinhu che solar kupisa vaunganidzi uye kupisa-kuitisa goko zvinhu zvine yunifomu kupisa kupisa.
4. Yakapfava uye processability
Pamusoro pehunhu hwezvakajairwa kabhoni, machira akarukwa kabhoni ane anisotropic kupfava kwakakosha muchitarisiko uye anogona kugadziriswa kuita machira akasiyana.Nekuda kwesimba radzo diki chairo, vanoratidza simba rakakwirira pamwe neiyo fiber axis.Carbon fiber yakasimbisa zvindori Oxygen resin composite zvinhu zvine yakakwira yakazara zviratidzo zvesimba chairo uye chaiyo modulus pakati pezvivakwa zviripo.
5. Kuderera kwekushisa kwepasi
Carbon fiber ine yakanaka yakaderera tembiricha kuramba, senge isina brittle pasi pemvura tembiricha yenitrogen.
6. Corrosion resistance
Carbon fiber ine yakanaka corrosion kuramba kune general organic solvents, acids, uye alkalis.Hainyungudika kana kuzvimba.Iyo ine yakatanhamara corrosion resistance uye haina dambudziko rekuita ngura.
7. Kuramba kwakanaka kupfeka
Carbon fiber nesimbi hazviwanzopfekwa pakukweshana.Carbon fiber inoshandiswa kutsiva asbestos kugadzira yakakwirira-giredhi friction zvinhu, izvo zvakashandiswa semabhureki pad zvinhu zvendege nemotokari.
8. Good high tembiricha kuramba
Kuita kwekabhoni fiber kwakanyatsogadzikana pasi pe400 ° C, uye hapana shanduko yakawanda kunyange pa1000 ° C.Kunyanya kupisa kwekushisa kwezvinhu zvinosanganiswa zvakanyanya kunoenderana nekupisa kwekupisa kwematrix.Kureba kwekupisa kwekupisa kweresin-based composite zvinhu zvinongoita 300 ℃, uye kupisa kwakanyanya kweceramic-based, carbon-based uye metal-based composite zvinhu zvinogona kuenderana nekabhoni fiber pachayo.Carbon fiber composite zvinhu zvinoshandiswa zvakanyanya muindasitiri yeaerospace seyakakwira tembiricha inodzivirira zvinhu.
9. Kunaka kwakanakisa
Carbon faibha ine hunyoro hwakanakisa (chimwe chezviratidziro zvehunyoro nhamba yemagiramu e9000-mita-yakareba fiber), kazhinji ingangoita magiramu gumi nemapfumbamwe, uye simba rekusimba rinosvika 300 kg pamicron.Zvishoma zvimwe zvinhu zvine akawanda emhando yepamusoro senge kabhoni fiber.
10. Kusagadzikana kwemaitiro kuramba uye nyore kukuvadza
Oxidation inoitika pasi pekuita kweasidhi yakasimba, iyo electromotive simba yekabhoni fiber yakanaka, uye iyo electromotive simba realuminium alloy haina kunaka.Kana kabhoni fiber composite zvinhu zvichishandiswa zvakasanganiswa nealuminium alloys, simbi carbonization, carburization uye electrochemical corrosion ichaitika.Naizvozvo, kabhoni faibha inofanirwa kugadziriswa pamusoro isati yashandiswa.
