Hauv lub ntiaj teb kev tsim khoom siv dav hlau uas muaj kev pheej hmoo siab, txhua gram tseem ceeb. Thaum kev lag luam dav hlau nce ntxiv thiab cov ntawv thov drone nthuav dav, kev lag luam ntsib ob qhov kev cov nyom tsis tau muaj dua: ua tiav qhov hnyav txo qis tshaj plaws thaum tswj hwm kev ruaj khov ntawm cov qauv. Cov khoom siv carbon fiber precision tau tshwm sim ua qhov kev daws teeb meem kawg, txhawb nqa los ntawm cov pov thawj zoo.
Daim ntawv tshaj tawm no nthuav tawm plaub qhov kev ntsuas kev ua tau zoo tseem ceeb los ntawm kev sim ua tib zoo uas qhia tau tias vim li cas cov khoom sib xyaw carbon fiber thiaj li dhau los ua cov khoom siv xaiv rau cov khoom siv hauv aerospace.
Kev Ntsuas 1: Lub Zog Tshwj Xeeb - Qhov Sib Piv Qhov Hnyav-rau-Lub Zog Uas Txhais Dua Qhov Ua Tau Zoo
Kev Sib Piv Cov Ntaub Ntawv Xeem:
| Khoom siv | Lub zog Tensile (MPa) | Qhov Ceev (g/cm³) | Lub Zog Tshwj Xeeb (MPa·cm³/g) |
|---|---|---|---|
| Cov Khoom Siv Carbon Fiber Composite (Qib T800) | 5,690 | 1.76 | 3,233 |
| Txhuas Alloy 7075-T6 | 572 | 2.70 | 212 |
| Hlau Muaj Zog Siab | 1,500 | 7.85 | 191 |
Kev Tshawb Pom Tseem Ceeb: Cov khoom sib xyaw ua los ntawm carbon fiber qhia tau tias muaj lub zog tshwj xeeb kwv yees li 15 npaug ntau dua li cov hlau txhuas thiab 17 npaug ntau dua li cov hlau muaj zog siab.
Kev Cuam Tshuam Hauv Lub Ntiaj Teb Tiag:
Rau cov chaw tsim khoom siv aerospace, qhov no txhais tau ncaj qha mus rau hauv cov txiaj ntsig kev ua haujlwm:
- Cov Kev Siv Satellite: Txhua 1 kg txo qhov hnyav ntawm lub satellite txuag tau kwv yees li 500 kg roj foob pob hluav taws thiab txo cov nqi tua los ntawm $ 20,000
- Kev Them Nqi Drone: Cov khoom siv carbon fiber tuaj yeem ua rau muaj peev xwm them tau ntau dua 30-40% piv rau cov khoom sib npaug ntawm txhuas
- Kev Siv Roj Zoo: Cov dav hlau lag luam siv cov khoom sib xyaw ua los ntawm carbon fiber ua tiav qhov hnyav txo tau 20-25%, ua rau txuag roj tau ntau heev thaum lub sijhawm ua haujlwm
Metric 2: Thermal Expansion Coefficient - Kev Ruaj Ntseg Ntawm Qhov Kub Thiab Txias
Kev Sib Piv Cov Ntaub Ntawv Xeem:
| Khoom siv | Coefficient ntawm Thermal Expansion (CTE) (10⁻⁶/K) |
|---|---|
| Cov Khoom Siv Carbon Fiber Composite (Longitudinal) | -0.5 txog 0.5 |
| Txhuas Alloy 6061 | 23.6 |
| Titanium Alloy Ti-6Al-4V | 9.0 |
| Hlau tsis xeb 304 | 17.3 |
