Carbon fiber iri kutsiva aluminium mukuwedzera kwakasiyana kwekushandisa uye yanga ichidaro kwemakumi mashoma emakore apfuura. Aya mafibhi anozivikanwa nekusimba kwawo uye kusimba uye zvakare akareruka zvakanyanya. Carbon fiber tambo dzakasanganiswa neakasiyana resin kugadzira zvinhu zvinoumbwa. Izvi zvinoumbwa zvinhu zvinotora mukana wezvimiro zvezvose zviri zviviri fiber uye resin. Ichi chinyorwa chinopa kuenzanisa kwezvinhu zvekabhoni fiber maringe nealuminium, pamwe nezvimwe zvakanakira nezvazvakaipira zvechinhu chimwe nechimwe.
Carbon Fiber vs Aluminium Measured
Pazasi pane tsananguro dzezvakasiyana zvivakwa zvinoshandiswa kuenzanisa zvinhu zviviri izvi:
Modulus ye elasticity = Iyo "kuoma" kwechinhu. Reshiyo yestress kustress yechinhu. Kutenuka kwestress vs strain curve yechinhu chiri munzvimbo yayo elastic.
Ultimate tensile simba = iyo yakanyanya kudzvinyirira chinhu chinogona kumira pamberi pekutyoka.
Density = huwandu hwezvinhu pahuwandu hweyuniti.
Kuomarara chaiko = Modulus ye elasticity yakakamurwa nekuwanda kwechinhu. Inoshandiswa kuenzanisa zvinhu zvine density dzakasiyana.
Chaiyo tensile simba = Tensile simba rakakamurwa ne density yezvinhu.
Neruzivo urwu mupfungwa, chati inotevera inofananidza kabhoni fiber nealuminium.
Cherechedza: Zvinhu zvakawanda zvinogona kukanganisa nhamba idzi. Aya ndiwo ma generalizations; kwete zviyero zvakakwana. Semuyenzaniso, akasiyana kabhoni faibha zvinhu zvinowanikwa nekuomarara kwepamusoro kana kusimba, kazhinji nekutengeserana mukuderedza zvimwe zvivakwa.
| Kuyera | Carbon Fiber | Aluminium | Carbon/Aluminium Kuenzanisa |
| Modulus ye elasticity (E) GPa | 70 | 68.9 | 100% |
| Kusimba kwesimba (σ) MPa | 1035 | 450 | 230% |
| Density (ρ) g/cm3 | 1.6 | 2.7 | 59% |
| Kuomarara chaiko (E/ρ) | 43.8 | 25.6 | 171% |
| Simba chairo rekusimba (σ /ρ) | 647 | 166 | 389% |
Chati iyi inoratidza kuti kabhoni faibha ine simba chairo rekusimba ringangoita 3.8 nguva yearuminiyamu uye kuoma chaiko kwe1.71 nguva yealuminium.
Kufananidza kupisa kwekabhoni fiber uye aluminium
Zvimwe zviviri zvimiro zvinoratidza mutsauko uripo pakati pekabhoni faibha nealuminium kuwedzera kwekupisa uye kupisa kwemhepo.
Kuwedzera kupisa kunotsanangura kuti hukuru hwechinhu hunoshanduka sei kana tembiricha yachinja.
| Kuyera | Carbon Fiber | Aluminium | Aluminium/Carbon Kuenzanisa |
| Kuwedzera kupisa | 2 mukati/°F | 13 mukati/°F | 6.5 |
Aluminium ine kanenge katanhatu kuwedzera kwekupisa kwekabhoni fiber.
Zvayakanakira nezvayakaipira
Paunenge uchigadzira zvepamberi zvinhu uye masisitimu, mainjiniya anofanirwa kuona kuti ndezvipi zvivakwa zvezvinhu zvakanyanya kukosha kune chaiwo maapplication. Kana simba guru-ku-kurema kana kuoma-kurema-kurema zvinhu, carbon fiber ndiyo sarudzo iri pachena. Panyaya yedhizaini, kana huremu hwakawedzerwa hunogona kupfupisa kutenderera kwehupenyu kana kutungamira mukutadza kuita zvakanaka, vagadziri vanofanirwa kutarisa kune kabhoni fiber sechinhu chiri nani chekuvaka. Kana kuoma kwakakosha, kabhoni fiber inosanganiswa nyore nezvimwe zvinhu kuti uwane hunhu hunodiwa.
Carbon fiber's low thermal expansion zvivakwa zvakakosha pakugadzira zvigadzirwa zvinoda dhigirii rechokwadi, uye kugadzikana kwedimensional mumamiriro ezvinhu apo tembiricha dzinochinja: michina yemaziso, 3D scanner, telescopes, nezvimwe.
Kune zvakare mashoma akashata ekushandisa kabhoni fiber. Carbon fiber haina kubereka. Pasi pemutoro, kabhoni fiber inokotama asi haizoenderana zvachose nechimiro chitsva (elastic). Kamwe simba rekupedzisira rekusimba kwekabhoni fiber zvinhu zvapfuura kabhoni fiber inotadza kamwe kamwe. Mainjiniya anofanirwa kunzwisisa maitiro aya uye anosanganisira kuchengetedza zvinhu kuti azvidavirire paanenge achigadzira zvigadzirwa. Carbon faibha zvikamu zvinodhura zvakanyanya kupfuura aruminiyamu nekuda kwemutengo wakakwira kugadzira kabhoni faibha uye hunyanzvi hukuru uye ruzivo rwakabatanidzwa mukugadzira emhando yepamusoro zvikamu zvakaumbwa.
