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

Los ntawm qhov kev xav ntawm cov ntaub ntawv kev tshawb fawb thiab kev lag luam kev lag luam, daim ntawv no tau txheeb xyuas cov xwm txheej ntawm txoj kev loj hlob, cov kev tsis sib haum xeeb thiab cov qauv yav tom ntej ntawm cov khoom siv fiber ntau hauv kev lag luam qis qis. Kev tshawb fawb qhia tau hais tias txawm hais tias cov pa roj carbon fiber ntau muaj txiaj ntsig zoo hauv lub dav hlau sib sib zog nqus, kev tswj tus nqi, kev ua kom zoo dua qub thiab kev tsim kho cov txheej txheem tseem yog qhov tseem ceeb txwv tsis pub nws daim ntawv thov loj.

1. Kev soj ntsuam ntawm kev sib raug zoo ntawm cov khoom siv carbon fiber ntau nrog kev lag luam qis qis

Qhov zoo ntawm mechanical zog:

• Lub zog tshwj xeeb ncav cuag 2450MPa / (g / cm³), uas yog 5 npaug ntawm aviation aluminium alloy
• Cov modulus tshwj xeeb tshaj 230GPa / (g / cm³), nrog rau qhov hnyav txo qhov hnyav

Kev siv nyiaj txiag:

• Txo qhov hnyav ntawm cov qauv drone los ntawm 1kg tuaj yeem txo lub zog siv li ntawm 8-12%
• Rau txhua 10% qhov hnyav txo ntawm eVTOL, qhov kev caij nkoj nce 15-20%

2. Cov xwm txheej tam sim no ntawm kev tsim kho kev lag luam

Ntiaj teb no kev lag luam qauv:

• Hauv 2023, lub ntiaj teb tag nrho cov kev thov rau carbon fiber yuav yog 135,000 tons, ntawm uas aerospace suav txog 22%.
• Nyiv Toray tuav 38% ntawm lub khw me me.

Kev vam meej hauv tsev:

• Kev loj hlob txhua xyoo ntawm kev tsim muaj peev xwm nce mus txog 25% (2018-2023).
• Lub zos tus nqi ntawm T700 tshaj 70%, tab sis T800 thiab saum toj no tseem cia siab rau imports.

3. Qhov tseem ceeb technical bottlenecks

Khoom qib:

• Prepreg txheej txheem stability (CV tus nqi yuav tsum tau tswj nyob rau hauv 3%)
• Cov khoom siv sib txuas sib txuas ua ke lub zog (yuav tsum ncav cuag ntau dua 80MPa)

Kev tsim khoom:

• Automated nteg efficiency (tam sim no 30-50kg / h, phiaj 100kg / h)
• Curing cycle optimization (cov txheej txheem autoclave ib txwm siv sijhawm 8-12 teev)

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

Kev ua lag luam xav tau kev kwv yees:

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

Kev tsim kho technology tiam sis:

• Tus nqi qis (lub hom phiaj txo $ 80-100 / kg)
• Intelligent manufacturing (application of digital twin technology)
• Recycling thiab rov siv dua (kev txhim kho kev siv tshuaj chemical recycling)
