Cov Khoom Siv Carbon Fiber Composites: Cov Khoom Siv Tseem Ceeb thiab Cov Kev Sib Tw rau Kev Txhim Kho Kev Lag Luam Qis-Altitude

Los ntawm qhov kev xav ntawm cov ntaub ntawv tshawb fawb thiab kev lag luam kev lag luam, daim ntawv no tshuaj xyuas qhov xwm txheej kev txhim kho, kev txwv tsis pub siv tshuab thiab cov qauv yav tom ntej ntawm cov ntaub ntawv sib xyaw ua los ntawm carbon fiber hauv kev lag luam qis. Kev tshawb fawb qhia tau hais tias txawm hais tias carbon fiber muaj qhov zoo tseem ceeb hauv kev ua kom lub dav hlau tsis hnyav, kev tswj tus nqi, kev ua kom zoo dua qub thiab kev tsim kho tus qauv tseem yog cov yam tseem ceeb uas txwv nws daim ntawv thov loj.

1. Kev tshuaj xyuas qhov sib xws ntawm cov khoom siv carbon fiber nrog kev lag luam qis-qhov siab

Cov txiaj ntsig ntawm cov khoom siv kho tshuab:

• Lub zog tshwj xeeb ncav cuag 2450MPa / (g / cm³), uas yog 5 npaug ntawm cov hlau txhuas aviation
• Cov qauv tshwj xeeb tshaj 230GPa / (g / cm³), nrog rau qhov hnyav txo qis tseem ceeb

Daim ntawv thov kev lag luam:

• Kev txo qhov hnyav ntawm cov qauv drone los ntawm 1kg tuaj yeem txo qhov kev siv hluav taws xob los ntawm kwv yees li 8-12%.
• Rau txhua 10% qhov hnyav txo ntawm eVTOL, qhov deb ntawm kev caij nkoj nce ntxiv 15-20%

2. Qhov xwm txheej tam sim no ntawm kev txhim kho kev lag luam

Cov qauv kev lag luam thoob ntiaj teb:

• Xyoo 2023, tag nrho cov kev thov thoob ntiaj teb rau carbon fiber yuav yog 135,000 tons, uas aerospace suav rau 22%.
• Toray Nyiv Pooj muaj 38% ntawm kev lag luam rub me me.

Kev nce qib hauv tebchaws:

• Tus nqi loj hlob txhua xyoo ntawm lub peev xwm tsim khoom ncav cuag 25% (2018-2023).
• Tus nqi ntawm T700 hauv zos tshaj 70%, tab sis T800 thiab siab dua tseem vam khom kev xa khoom tuaj.

3. Cov teeb meem tseem ceeb ntawm kev siv tshuab

Cov khoom siv theem:

• Kev ruaj khov ntawm cov txheej txheem Prepreg (tus nqi CV yuav tsum tau tswj hwm hauv 3%)
• Lub zog sib txuas ntawm cov khoom sib xyaw ua ke (yuav tsum ncav cuag ntau dua 80MPa)

Cov txheej txheem tsim khoom:

• Kev ua haujlwm ntawm kev tso tsis siv neeg (tam sim no 30-50kg / teev, lub hom phiaj 100kg / teev)
• Kev kho lub voj voog kom zoo (txheej txheem autoclave ib txwm siv sijhawm 8-12 teev)

4. Kev cia siab rau kev siv nyiaj txiag qis-qhov siab

Kev kwv yees qhov xav tau ntawm kev ua lag luam:

• Kev thov rau eVTOL carbon fiber yuav ncav cuag 1,500-2,000 tons hauv xyoo 2025.
• Kev thov hauv thaj chaw drone yuav tshaj 5,000 tons hauv xyoo 2030

Cov qauv kev loj hlob ntawm thev naus laus zis:

• Tus nqi qis (lub hom phiaj txo qis rau $ 80-100 / kg)
• Kev tsim khoom ntse (kev siv thev naus laus zis digital twin)
• Kev siv dua tshiab thiab kev siv dua tshiab (kev txhim kho kev ua haujlwm ntawm txoj kev siv tshuaj rov qab)
