Umatshini weCarbon fiber braidingsikwinqanaba eliphezulu ngokwentelekisoumatshini wokulukaimveliso yolu thotho koomatshini bokuphotha.Xa kuthelekiswa nezinto ezilukiweyo zemveli ezifana nentambo yomqhaphu kunye nocingo lwentsimbi, umatshini wokuluka ifayibha yekhabhoni uneemfuno eziphezulu zobuchwepheshe kunye noyilo oluntsonkothileyo kunye nokuvelisa.
Nangona kunjalo, alinakuphikiswa ukuba xa kuthelekiswa nezinto ezilukiweyo zemveli, i-carbon fiber weaving ineempawu ezintle kakhulu, kwaye ikamva layo lesicelo libanzi.Esi sesinye sezizathu zokuba iBenfa iTekhnoloji isoloko isenza itekhnoloji yokuluka i-carbon fiber ibe yeyona ndlela iphambili yokuphumelela.
Xa kuthelekiswa nezinto ezilukiweyo zemveli, zeziphi iimpawu zemathiriyeli ye-carbon fiber?
1. Amandla okuqina aqinile
Amandla obunzima be-carbon fiber malunga ne-2 ukuya kwi-7 GPa, kwaye imodyuli ye-tensile i malunga ne-200 ukuya kwi-700 GPa.Ubuninzi bumalunga ne-1.5 ukuya kwi-2.0 grams nge-cubic centimeter, eyona nto inqunywe ngubushushu benkqubo ye-carbonization ngaphezu kwesakhiwo se-silk yasekuqaleni.Ngokubanzi emva kobushushu obuphezulu 3000℃ unyango graphitization, ingxinano ingafikelela 2.0 grams cubic centimitha nganye.Ukongeza, ubunzima bayo bulula kakhulu, ubunzima bayo obuthile bulula kune-aluminium, bungaphantsi kwe-1/4 yentsimbi, kwaye amandla ayo athile aphindwe ngama-20 entsimbi.I-coefficient yokwandisa i-thermal ye-carbon fiber ihluke kwezinye iifayili, kwaye ineempawu ze-anisotropy.
2. I-coefficient yokwandiswa kwe-thermal encinci
I-coefficient yokwandisa i-thermal ye-carbon fiber ngokwayo ayinayo ngaphakathi (-0.5 ~ -1.6) × 10-6 / K, ingu-zero ku-200-400 ℃, kunye ne-1.5 × 10-6 / K xa ingaphantsi kwe-1000 ℃ .Izinto ezidibeneyo ezenziwe ngayo zine-coefficient yokwandisa ezinzile kwaye ingasetyenziselwa njengesixhobo esiqhelekileyo sokulinganisa.
3. Ukuqhuba kakuhle kwe-thermal
Ngokuqhelekileyo, i-thermal conductivity ye-inorganic kunye ne-organic materials ihlwempuzekile, kodwa i-thermal conductivity ye-carbon fiber isondele kwintsimbi.Ukuthatha inzuzo yale nzuzo, ingasetyenziselwa njengezinto zokuqokelela ukushisa kwelanga kunye ne-sheet-conducting shell material kunye nokudluliselwa kobushushu obufanayo.
4. Ithambile kwaye iyaqhubekeka
Ukongeza kwiimpawu zemathiriyeli yekhabhoni ngokubanzi, amalaphu alukiweyo ekhabhoni ane-anisotropic ethambileyo ebonakalayo kwaye anokucutshungulwa abe ngamalaphu ahlukeneyo.Ngenxa yobunzima bazo obuthile obuthile, babonisa amandla aphezulu ecaleni kwe-fiber axis.Izangqa zeCarbon fibre eziqinisiweyo Izixhobo ezihlanganisiweyo ze-oxygen resin zinezona zibonakaliso ziphezulu zamandla athile kunye nemodyuli ethile phakathi kwezinto ezikhoyo zesakhiwo.
5. Ukumelana nobushushu obuphantsi
Ifayibha yekhabhoni inokumelana kakuhle nobushushu obuphantsi, obufana nokungashwabanisi phantsi kobushushu benitrogen.
6. Ukumelana nokubola
Ifayibha yekhabhon inokumelana ne-corrosion elungileyo kwizinyibilikisi eziqhelekileyo ze-organic, iiasidi, kunye neealkali.Ayinyibiliki okanye idumbe.Inamandla okumelana nomhlwa kwaye ayinayo ingxaki yomhlwa.
7. Ukumelana nokunxiba kakuhle
Ifayibha yekhabhoni kunye nentsimbi azifane zinxitywe xa zikhuhlana.Ifayibha yekhabhoni isetyenziselwa ukubuyisela iasbestos ukwenza izinto zodidi oluphezulu, eziye zasetyenziswa njengezixhobo zokuqhobosha iinqwelomoya kunye neemoto.
8. Ukumelana nobushushu obuphezulu
Ukusebenza kwe-carbon fiber kuzinzile kakhulu ngaphantsi kwe-400 ° C, kwaye akukho tshintsho oluninzi nakwi-1000 ° C.Ukumelana nobushushu obuphezulu bezinto ezidibeneyo zixhomekeke ikakhulu ekuxhathiseni ukushisa kwe-matrix.Ukumelana nobushushu bexesha elide lezinto ezixutywe ne-resin-based based composite kuphela malunga ne-300 ℃, kunye nokumelana nokushisa okuphezulu kwe-ceramic-based, i-carbon-based and metal-based composite materials inokuhambelana ne-carbon fiber ngokwayo.Izixhobo zekhabhoni zefiber composite zisetyenziswa kakhulu kwishishini le-aerospace njengezinto ezixhathisa ubushushu obuphezulu.
9. Ukulunga okugqwesileyo
Ifayibha yekhabhoni inokulunga okugqwesileyo (enye yezinto ezibonisa ukucoleka linani leegram ze-9000 yemitha-ubude befayibha), ngokubanzi kuphela malunga ne-19 grams, kunye namandla okuqina afikelela kuma-300 kg kwimicron nganye.Zimbalwa ezinye izixhobo ezineepropathi ezininzi ezigqwesileyo njenge-carbon fiber.
10. Ukuchasana kwempembelelo embi kwaye kulula ukonakalisa
I-oxidation yenzeke phantsi kwesenzo se-asidi eqinile, amandla e-electromotive ye-carbon fiber ilungile, kwaye i-electromotive force ye-aluminium alloy ayinayo.Xa izinto ze-carbon fiber composite zisetyenziselwa ukudibanisa kunye ne-aluminium alloys, i-carbonization yensimbi, i-carburization kunye ne-electrochemical corrosion iya kwenzeka.Ngoko ke, i-carbon fiber kufuneka iphathwe phezulu ngaphambi kokusetyenziswa.
