Cij txwv txog cov tshuaj tiv thaiv kab mob carbon fiber
1.1 cim kev sib xyaw: Qhov kawg kev txhais ntawm carbon
Qhov no "dub cov khoom siv kub" nrog cov ntsiab lus carbon ntawm ntau tshaj 95% yog woven rau hauv ib lub cheeb ntawm 5-10 micrrod ntawm microcrite microcrystals raws li pob txha. Nws qhov ntom ntom tsuas yog 1/4 ntawm cov hlau, tab sis nws lub zog yog 7-9 lub zog yog 7-9 lub zog yog 7-9 lub zog yog 7-9 lub sij hawm uas ntawm cov hlau, ib yam li ntau tus pej thuam Eiffel ntau dua.
1.2 microscopic txujcis: chaotic graphite qauv
Nyob rau hauv lub tshuab hluav taws xob hauv tshuab hluav taws xob, carbon fiber ntau nthuav tawm cov ntawv tshwj xeeb " Tus qauv tshwj xeeb no muab nws amazing anisotropy {}} lub zog yog sib piv rau pob zeb diamond, tab sis nws yog mos thiab tuaj yeem ua rau kab rov tav.
Key parameter sib piv cov lus
| Kev Ua Haujlwm Performance index|Cov nqi ib txwm muaj carbon fiber|Kev sib piv tus nqi ntawm aluminium alloy |
|-----------|--------------|--------------|
| Ntawj (G /M³)|1.75|2.7 |
| Lub zog tensile (GPA)|3.5-7.0|0.3-0.5 |
| Elastic modulus (GPA)|200-700|68-70 |
Cov Tshuaj Ntsej Muag Carbon Fiber
2.1 Keeb kwm txiav txim siab txoj hmoo: Peb cov khoom raw khoom loj
-PAN-based (accounting for 90% of the world): the gorgeous transformation of acrylonitrile, the road to counterattack from chemical fiber to aerospace materials
Asphalt - Raws li cov roj rov qab los ntawm - tub rog "tshwj xeeb} high} high} high} high} high kub scenes
- Viscose {- Raws li: kev hloov pauv ntawm cellulose, cov neeg saib xyuas pom ntawm cov neeg saib xyuas ntawm cov tswv cuab
2.2 Kev nce qib - los ntawm pej xeem rau tub rog
Thaum T300 carbon fiber (lub zog 3530MPA) ntsib M60 Modulus fiber ntau (M65J Composite Fiber ntau yog recefining cov kev txwv ntawm cov ntaub ntawv.
Los ntawm chav kuaj rau cov kab ntau lawm: kev tsim khoom tsim tau
3.1 Cov lus ntawm kev yug los ntawm ntau txhiab tus ntawm kev sim siab thiab kev txom nyem
1. Raw Silk Spining: Kev tswj kom muaj qhov nrawm thiab ntub dej yog sib npaug rau carving micron {}}} qib grooves ntawm cov plaub hau
2. Ua ntej -} xidation "ntawm 200-300 degree, uas hloov cov qauv molecular los ntawm kab los mus rau trapezoidal qauv
3
4. Graphitization: Ultra {{1} he} Siab siab Sublimation ntawm 3000℃tiav qhov kawg cov khoom siv
Tshuab kev sib tw: rau txhua 100℃nce hauv graphitization kub, tus nqi tsim khoom nce siab nthuav dav. Qhov no yog qhov pib logic ntawm lub siab-} xaus carbon fiber nqe piv.
Ciam Nrho Breaker: Qhov Infinite Peev Xwm ntawm Carbon Fiber
- Aerospace: Boeing 787 Dreamliner siv cov khoom siv Fiber ntau rau 50%, txo qhov hnyav los ntawm 20%
-} Lub Zog Tshiab Zog: Tesla Cybertruck lub plhaub Exoskeleto qhib lub sijhawm tshiab
-}} {-} Cov neeg ua kis las muaj zog ntawm cov neeg muaj lub cev ua si los sib tw ntawm tib neeg lub cev, nrog kev nrawm ntawm 30 km
- yav tom ntej kev xav: tus kheej {{1} {1} Cov ntxaij cov ntxaij vab tshaus fiber ntau, cov pob tshab cov ntxaij vab tshaus, chaw nce of theator cable ...
Cov ntaub ntawv kev lag luam: Xyoo 2023, thoob ntiaj teb yuav ncav cuag cov khoom muaj peev xwm ntau dua 50%, tab sis tus kheej} Qhov no yog ob qho nyuaj thiab muaj cib fim.
