Feem ntau, qhov ntev ntawm ultra-luv carbon fiber yog nyob nruab nrab ntawm 0.1 - 5 hli, thiab lawv qhov ntom ntom yog tsawg ntawm 1.7 - 2G / cm³. Nrog lub ntom ntom ntom ntawm 1.7 - 2.2g / cm³, lub tensile lub zog ntawm 3000 - 700GPA, cov kws kho mob zoo heev rau nws siv hauv kev thauj khoom-cov kabmob. Tsis tas li ntawd, nws muaj qhov kub siab ua tsis tau zoo, thiab tuaj yeem tiv taus qhov kub ntawm ntau dua 2000 ° C hauv qhov tsis yog-oxidizing huab cua.

Cov ntawv thov tshuab thiab cov txheej txheem ntawm ultra-luv carbon fiber hauv aerospace teb

Hauv Aerospace teb, ultra-luv carbon fiber feem ntau yog siv los txhawbtsiajMatrix Composites. Tus yuam sij ntawm thev naus laus zis yog ua kom cov pa roj carbon fyees tawg nyob rau hauv lub resin matrix. Piv txwv li, tau txais ultrasonic dismersion tshuab tuaj yeem ua rau muaj kev lom zem ntawm carbon fiber ntau dua 90%, ua kom muaj cov khoom siv sib xws. Nyob rau tib lub sijhawm, kev siv cov fiber ntau cov tshuab kho mob, xws li kev sivCoupling Tus Neeg Sawv Cevkho, tuaj yeem ua rau tusCarbon FiberThiab Resin interterface ber zog nce los ntawm 30% - 50%.

Hauv kev tsim cov dav hlau wings thiab lwm cov txheej txheem txheej txheem, kev siv cov tshuab kub nias lub tank. Ua ntej tshaj plaws, cov ultra-luv carbon fiber thiab resin tov nrog qee qhov ua haujlwm ua los ntawm excorted rau hauv cov xovxwm kub kub. Nws yog tom qab ntawd kho thiab pwm ntawm qhov kub ntawm 120 - 180 ° C thiab lub siab ntawm 0.5 - 1.5MPA. Tus txheej txheem no tuaj yeem tshem tawm cov pa npuas hauv cov khoom sib xyaw ua kom muaj qhov sib npaug thiab kev ua haujlwm siab ntawm cov khoom.

Tshuab thiab cov txheej txheem rau daim ntawv thov ntawm ultra-luv carbon fiber hauv kev lag luam automotive

Thaum thov siv cov roj carbon-luv carbon fiber rau cov chaw automotive, kev tsom xam yog txhim kho nws cov kev sib raug zoo nrog cov khoom siv ua hauv paus. Los ntawm kev ntxiv cov lus sau ua ke tshwj xeeb, cov adhesion interfacial ntawm cov pa roj carbon fiber thiab cov khoom siv hauv paus (piv txwv li cov ntaub ntawv (piv txwv lipolyprropylene, thiab lwm yam) yuav nce ntxiv txog 40%. Nyob rau tib lub sijhawm, txhawm rau txhim kho nws qhov kev ua tau zoo hauv cov kev nyuaj siab uas tau siv los kho cov kev taw qhia ntawm fiber ntau raws li kev ntxhov siab ntawm ib feem.

Kev txhaj tshuaj molding yog feem ntau siv nyob rau hauv kev tsim cov khoom xws li tsheb hoods. Ultra-Luv Carbon Fiber tau sib xyaw nrog cov yas thiab tom qab ntawd txhaj rau hauv cov pwm kab noj hniav los ntawm kev kub siab thiab siab. Kev txhaj tshuaj kub feem ntau yog 200 - 280 ℃, kev txhaj tshuaj nias yog 50 - 150 MPA. Cov txheej txheem no tuaj yeem paub cov pa nrawm nrawm ntawm cov khoom sib xyaw ua ke, thiab tuaj yeem ua kom cov kev faib tawm ntawm cov tshuaj tua hluav taws xob ntawm cov khoom lag luam.

Cov cuab yeej siv thev naus laus zis thiab cov txheej txheem ntawm ultra-luv carbon fiber cov ntawv thov hauv cov khoom siv hluav taws xob

Hauv kev ua teb hluav taws xob dissipation, kev siv ntawm thermal conductivity ntawm ultra-luv carbon fiber yog qhov tseem ceeb. Los ntawm kev ua kom zoo dua ntawm graphitization degree ntawm carbon fiber, nws thermal conductivity tuaj yeem nce mus rau ntau dua 1000W / (MK). Lub caij no, kom ntseeg tau tias nws sib cuag zoo nrog cov tshuab hluav taws xob, xws li tshuaj lom neeg ua paug rau cov tshuaj lom neeg carbon fiber los ntawm ntau dua 80%.

Cov hmoov hlau me metallurgy tuaj yeem siv rau hauv kev tsim cov computer CPU cua sov. Cov ultra-luv carbon fiber yog tov nrog hlau hmoov tov (piv txwv li cov hmoov tooj liab) thiab sintered nyob rau hauv qhov kub thiab siab. Sinining kub feem ntau 500 - 900 ° C thiab lub siab yog 20 - 50 MPa. Tus txheej txheem no ua rau cov pa roj carbon fiber los ua ib qho kev kub kub ua kom sov nrog cov hlau thiab txhim kho qhov kub dissipation efficiency.

Los ntawm Aerospace mus rau cov khoom lag luam hauv tsheb hluav taws xob rau cov khoom siv hluav taws xob, nrog kev hloov kho nruam lub thev naus laus zis thiab cov txheej txheem ua kom zoo, ultra-luvCarbon FiberYuav ci rau hauv cov liaj teb ntau, txhaj ntau dua lub zog muaj zog rau niaj hnub kev tshawb fawb thiab kev txhim kho.
