Kev Sib Piv Txog Tus Nqi thiab Kev Ua Tau Zoo nrog Carbon Fiber (CFRP)
Kev Sib Piv: Basalt Fiber (BFRP) piv rau Carbon Fiber (CFRP)
| Qhov Loj | Basalt Cov Khoom Siv Fiber Ntau Ntxiv (BFRP) | Cov Khoom Siv Carbon Fiber Uas Muaj Zog Ntxiv (CFRP) |
| Tus nqi khoom siv | Cov Phaj: kwv yees li 60–100 RMB/kg (Hauv Tebchaws) | Cov Phaj: kwv yees li 150–300 RMB/kg (Qib T300) |
| Lub Zog Tshwj Xeeb | Nruab Nrab (≈250) | Siab (≈600) |
| Modulus tshwj xeeb | Tsawg Kawg (≈20) | Siab (≈60-100) |
| Kev Tiv Thaiv Kev Cuam Tshuam | Nruab Nrab (Brittleness ntau dua li CFRP) | Siab Zoo (Toughness Zoo) |
| Tus nqi ua haujlwm | Cov phaj pultruded yooj yim rau kev ua tiav, tab sis kev molding nyuaj xav tau cov txheej txheem ntxiv. | Tus nqi nias kub ntawm Prepreg siab heev, tab sis tso cai rau kev sib xyaw ua ke. |
| Kev ruaj khov | Kev qaug zog zoo, kev tiv thaiv corrosion zoo heev. | Kev ua haujlwm qaug zog zoo heev, tab sis xav tau kev tiv thaiv tiv thaiv galvanic corrosion. |
| Kev Txo Qhov Hnyav | Txo qhov hnyav 20–30% piv rau aluminium alloy. | Txo qhov hnyav 40–50% piv rau aluminium alloy. |
Kev Tshuaj Xyuas Qhov Xwm Txheej Txog Kev Siv Nyiaj Tau Zoo
- Cov drones uas pheej yig tshaj (piv txwv li, kev tshuaj xyuas, cov drones ua liaj ua teb): - BFRP tuaj yeem hloov qee cov khoom siv txhuas, nrog rau tus nqi qis dua 30-50% piv rau CFRP thiab kev tiv thaiv corrosion zoo dua, muab kev siv nyiaj ntau.
- Cov ntawv thov uas xav tau kev ruaj khov siab thiab tsim qauv sib dua (piv txwv li, kev sib tw drones, kev thaij duab los ntawm huab cua): - CFRP muaj qhov zoo dua hauv modulus ntawm elasticity, txo qhov aerodynamic deformation; txawm hais tias kim dua, nws qhov kev ua tau zoo tsis tuaj yeem hloov pauv.
- Cov ntawv thov nrog cov kev cai tshwj xeeb: Yog tias xav tau kev pom tseeb ntawm lub zog hluav taws xob lossis kev txo qis / kev co, BFRP tuaj yeem ua haujlwm ua cov khoom siv ntxiv rau cov khoom tshwj xeeb (piv txwv li, radar domes).
- Cov Kev Cov Teeb Meem Txog Kev Siv Tshuab thiab Cov Lus Qhia Txog Kev Txhim Kho
- Kev tsim qauv sib xyaw: BFRP + CFRP laminates: Tso cov carbon fiber hauv zos rau hauv cov cheeb tsam uas muaj qhov yuav tsum tau ua kom ruaj khov kom sib npaug tus nqi thiab kev ua tau zoo.
- Kev txhim kho cov txheej txheem: Tsim BFRP prepregs lossis 3D-luam tawm cov ntaub ntawv fiber-reinforced los txhim kho lub peev xwm los tsim cov qauv nyuaj.
- Kev sib txuas thev naus laus zis: Txais yuav cov pob qij txha sib xyaw ua ke uas muaj cov nplaum lossis kev vuam ultrasonic los txhim kho kev ua haujlwm ntawm kev sib koom ua ke.
Raws li qhov kev tshuaj xyuas saum toj no, BFRP yog qhov tsim nyog rau cov qauv nruab nrab-rau-qis-load hauv UAVs me me thiab muab cov nqi thov hauv cov nqe lus ntawm kev txo qhov hnyav, kev tiv thaiv corrosion, thiab damping / kev co txo; txawm li cas los xij, nws yuav tsum zam hauv thaj chaw uas xav tau kev tawv ncauj siab. Yog tias kev tawv ncauj tsis yog qhov tseem ceeb tab sis tus nqi yog, BFRP muab kev siv nyiaj zoo dua li CFRP.
Tsis tas li ntawd xwb, kev tsim qauv sib xyaw BFRP/CFRP tuaj yeem txiav txim siab los ua kom zoo dua cov nqi.
Kev tshuaj xyuas cov khoom siv finite (FEA) kuj tseem siv tau los ua qauv qhia txog cov khoom tshwj xeeb (xws li lub dav hlau), piv qhov hnyav thiab tus nqi ntawm BFRP thiab CFRP raws li cov yam ntxwv kev nyab xeeb sib npaug los tsav kev xaiv cov khoom siv raws li cov ntaub ntawv.
