Kev tsom xam ntawm cov tseem ceeb vim li cas rau lub siab tensile lub zog ntawm cov ntaub ntaub carbon fiber ntau

 

Kuv {. molecular qauv thiab crystal orientation
{{0 {}} txheej txheem kev teeb tsa ntawm cov pa roj
Carbon fiber yog tsim cov microcrystals, thiab carbon falcomb qauv ntawm ib txheej ntawm graphene tuaj yeem ncav cuag 130 GPA, thiab Qhov tseeb cov ntaub file cov fiber ntau tuaj yeem ncav cuag 4,900-7, {}} mpa.

{{0 {}}} crystal tswj
Thaum lub sij hawm cov txheej txheem carbonancation, kub (1,200-3 90% {{{}}

II {.} Cov txheej txheem tsim khoom lag luam
1. precursor xaiv
Cov ntsiab lus siv polyacrylonitrile (lauj kaub) -based fiber, thiab muaj ntau cov pa roj carbon fiber ntau dua li ntawm asphalual-based carbon fiber.

2. Cov pa hluav taws kub kub thiab hluav taws xob
- Tsawg-kub carbonancation ({400-800 degree): recogrogen, oxygen, oxygen) los ua ib lub turbostratic graphite qauv;
- Kev kub siab lug ntawm cov duab (2,500℃+): Txhawb nqa cov macon kev tiv thaiv mus rau ntau dua 600 gpa.

3. Kev Kho Mob Tshuab
Los ntawm kev kho ntshav hluav taws xob los yog ntshav kho mob, micro grooves yog tsim rau cov resin saum lub zog nrog lub zog kev ntxhov siab los ntawm kev sib txuas lus los ntawm kev sib txuas lus los ntawm kev sib txuas lus {}}

Iii {. Cov Khoom Tsim Tsim
1.} kev npaj fiber ntau
Cov ntaub pua muaj roj carbon fiber ntau dua los yog cov ntaub ntawv tsis muaj zog ntawm cov pa roj carbon monoxide. 80%

2.} tsis kho
- Qhov txoj kab uas hla ntawm cov xaim xaim nyoos yog tswj hwm ntawm 5-7 μm kom txo tau cov kab nrib pleb;
- qeeb cua sov ({1-5℃/ min) yog siv thaum lub sijhawm carbonancation kom inhibit tiam peri.
