Umshini wokuluka i-carbon fiberisezingeni eliphakeme uma kuqhathaniswaumshini wokulukaumkhiqizo walolu chungechunge lwemishini yokuluka.Uma kuqhathaniswa nezinto zokuluka zendabuko ezifana nentambo kakotini nentambo yensimbi, umshini wokuluka i-carbon fiber unezidingo eziphezulu zobuchwepheshe kanye nomklamo oyinkimbinkimbi nokukhiqiza.
Kodwa-ke, akunakuphikwa ukuthi uma kuqhathaniswa nezinto ezilukiwe zendabuko, ukwelukwa kwe-carbon fibre kunezici ezinhle kakhulu, futhi amathemba okusebenzisa kwayo esikhathini esizayo abanzi.Lesi ngesinye sezizathu ezenza ukuthi iBenfa Technology ihlale yenza ubuchwepheshe bokuluka i-carbon fibre ibe yinkomba ebalulekile yempumelelo.
Uma kuqhathaniswa nezinto ezilukiwe zendabuko, yiziphi izici ze-carbon fiber materials?
1. Amandla okuqina aqinile
Amandla aqinile we-carbon fibre cishe ku-2 kuya ku-7 GPa, futhi i-tensile modulus cishe i-200 kuya ku-700 GPa.Ukuminyana cishe ku-1.5 kuya ku-2.0 amagremu ku-cubic centimeter ngayinye, okunqunywa ngokuyinhloko izinga lokushisa lenqubo ye-carbonization ngaphezu kwesakhiwo sikasilika wangempela.Ngokuvamile ngemva kokwelashwa kwe-graphitization kwezinga lokushisa eliphezulu elingu-3000℃, ukuminyana kungafinyelela ku-2.0 amagremu ku-cubic centimeter ngayinye.Ngaphezu kwalokho, isisindo sayo silula kakhulu, amandla ayo adonsela phansi athile alula kune-aluminium, angaphansi kwe-1/4 yensimbi, futhi amandla ayo akhethekile aphindwe izikhathi ezingu-20 kunensimbi.I-coefficient yokwandisa okushisayo ye-carbon fiber ihlukile kweminye imicu, futhi inezici ze-anisotropy.
2. I-coefficient encane yokwandisa ukushisa
I-thermal expansion coefficient yeningi le-carbon fiber ngokwayo inegethivu ngaphakathi (-0.5~-1.6)×10-6/K, inguziro ku-200-400℃, kanye no-1.5×10-6/K uma ingaphansi kuka-1000℃ .Izinto eziyinhlanganisela ezenziwe ngayo zine-coefficient enwetshiwe ezinzile futhi ingasetshenziswa njengethuluzi lokukala elijwayelekile.
3. Good conductivity ezishisayo
Ngokuvamile, ukuhanjiswa okushisayo kwezinto ezingaphili kanye ne-organic akulungile, kodwa ukuqhutshwa kokushisa kwe-carbon fiber kusondelene naleyo yensimbi.Ukusebenzisa le nzuzo, ingasetshenziswa njengempahla yabaqoqi bokushisa kwelanga kanye nempahla yegobolondo eqhuba ukushisa ngokudluliswa kokushisa okufanayo.
4. Ithambile futhi iyasebenziseka
Ngaphezu kwezimpawu zezinto ezijwayelekile zekhabhoni, izindwangu ezilukiwe ze-carbon fiber zinokuthambile okubalulekile kwe-anisotropic ngokubukeka futhi zingacutshungulwa zibe izindwangu ezahlukahlukene.Ngenxa yamandla adonsela phansi amancane athile, abonisa amandla aphezulu eduze kwe-fiber axis.Izindandatho eziqiniswe nge-carbon fiber resin ene-oxygen resin enezinkomba eziphezulu kakhulu eziphelele zamandla athile kanye ne-modulus ethize phakathi kwezinto ezikhona zesakhiwo.
5. Ukumelana nokushisa okuphansi
I-Carbon fiber inokumelana okuhle kwezinga lokushisa eliphansi, njengokungashwabanisi ngaphansi kwezinga lokushisa le-nitrogen eliwuketshezi.
6. Ukumelana nokugqwala
I-Carbon fiber inokumelana okuhle nokugqwala kuzincibilikisi zemvelo ezijwayelekile, ama-asidi, nama-alkali.Ayincibiliki noma ivuvuke.Inokumelana nokugqwala okuvelele futhi ayinayo inkinga yokugqwala.
7. Ukumelana nokugqoka okuhle
I-carbon fibre nensimbi akuvamisile ukugqokwa uma kukhuhlwana.I-Carbon fiber isetshenziselwa ukufaka esikhundleni se-asbestos ukwenza izinto zokushayisana kwezinga eliphezulu, eziye zasetshenziswa njengezinto zokubopha amabhuleki ezindizeni nasezimotweni.
8. Ukumelana kahle nokushisa okuphezulu
Ukusebenza kwe-carbon fiber kuzinzile kakhulu ngaphansi kuka-400 ° C, futhi alukho ushintsho olukhulu ngisho naku-1000 ° C.Ukumelana nokushisa okuphezulu kwezinto ezihlanganisiwe ikakhulukazi kuncike ekuphikisweni kokushisa kwe-matrix.Ukumelana nokushisa kwesikhathi eside kwezinto ezihlanganisiwe ezisekelwe ku-resin cishe ku-300 ℃ kuphela, futhi ukumelana okuphezulu kwezinga lokushisa kwe-ceramic-based, carbon-based and metal-based composite materials kungahambisana ne-carbon fiber ngokwayo.I-Carbon fiber composite materials isetshenziswa kabanzi embonini ye-aerospace njengezinto eziphikisana nokushisa okuphezulu.
9. Ukucoleka okuhle kakhulu
I-Carbon fiber inobuhle obuhle kakhulu (okunye okubonisa ukucoleka inombolo yamagremu efayibha yobude obungamamitha angu-9000), ngokuvamile cishe amagremu angu-19 kuphela, namandla aqinile afinyelela ku-300 kg ngemicron ngayinye.Zimbalwa ezinye izinto ezinezici ezinhle kakhulu njenge-carbon fiber.
10. Ukumelana nomthelela ongemuhle futhi kulula ukulimaza
I-oxidation kwenzeka ngaphansi kwesenzo se-asidi eqinile, amandla e-electromotive e-carbon fiber alungile, futhi amandla e-electromotive we-aluminium alloy anegethivu.Lapho i-carbon fiber composite materials isetshenziswa ngokuhambisana nama-alloys e-aluminium, i-carbonization yensimbi, i-carburization kanye nokugqwala kwe-electrochemical kuzokwenzeka.Ngakho-ke, i-carbon fiber kufanele ilashwe ngaphezulu ngaphambi kokusetshenziswa.
