Cov kev txiav txim siab dua Carbon Fiber cov fiberers xa mus rau cov pa roj carbon fibers nrog lub zog tensile lub zog (ntau dua 4.5 GPA) thiab high tensile modulus (ntau dua 250 GPA). Piv nrog rau cov pa roj carbon fiber ntau, high-ant-reas-excon fiber yog denser nyob rau hauv cov qauv thiab muaj tsawg dua tej yam, yog li nws muaj cov kws kho tshuab zoo dua thiab hluav taws xob ruaj khov.
Cov yam ntxwv ntawm High-kawg carbon fiberers
Lub zog siab: lub tensile lub zog ntawm qib carbon fiber yog {}}}}}}}}} dua 10 zaug ntawm txhuas alloy.
High Modulus: Lub tensile modulus ntawm high-Organ fiber yog {}}}}}}}} dua 5 zaug ntawm txhuas alloy.
Tsawg ntom ntom ntom: lub ntom ntawm high-kev txiav txim carbon fiber tsuas yog 1. {} G /} g / 1/4 ntawm cov hlau thiab 1/2 ntawm txhuas alloy.
Kev kub siab kuj: Cov roj carbon high-qib carbon fiber tuaj yeem tiv taus cov siab kub siab tshaj 2000 degree hauv cov inert golver ib puag ncig.
Corrosion Kuj: High-Order Carbon fibers tau zoo tshaj corrosion tsis kam rau tshuaj lom neeg xws li acids, alkalis, thiab ntsev.
Tsawg coefficient ntawm expansion: Cov coefficient ntawm thermal expansion ntawm high-forceasabers yog ze rau xoom, thiab qhov seem ruaj khov yog qhov zoo tshaj plaws ntawm qhov ntsuas kub.
Hluav taws xob thiab cua sov kev ua haujlwm: high-qib carbon fibers muaj hluav taws xob zoo thiab thermal condies thiab tuaj yeem hloov kho raws li xav tau.
Cov txheej txheem tsim khoom ntawm high-xaus carbon fiber
Cov txheej txheem tsim khoom ntawm high-kev txiav txim pa roj carbon fiber feem ntau suav nrog cov kauj ruam hauv qab no:
1
>>
Kev npaj precursor:
High-zoo polyacrylonitrile (lauj kaub) lossis asphalt yog xaiv los ua cov khoom siv raw, thiab cov txheej txheem ua ntej yog tsim los ntawm kev kiv, sau ntawv thiab lwm yam txheej txheem.

>>
Ua ntej-oxidation:
Lub prefursor yog pre-oxidized nyob rau hauv huab cua ntawm {1}} degree kom hla nws cov qauv molecular los ua cov qauv molecular los ua cov qauv molezoidal ruaj khov.

>>
Carbonity:
Lub pre-oxidized prefeor yog rhuab rau 1000-1500 degree hauv cov txiaj ntsig roj hauv cov pa roj inert ua kom nws cov peev txheej carbon ntau dua 90%.
4
>>
Graphitizitizitization:
Cov pa roj carbonized yog rhuab rau 2500-3000 degree hauv cov khoom siv roj crystallite ntau dua, thiab txhim kho cov modulus thiab lub zog ntawm cov fiber.
