Nws cov kev ua tau zoo ze li ntawm silica fiber, alumina-silica fiber, thiab ceramic fiber. Tsis tas li ntawd, nws qhov kev ruaj khov thermal shock zoo heev; nws cov kev ua tau zoo tseem ruaj khov ntawm 500 ℃, thiab nws tsuas yog poob 3% ntawm nws qhov hnyav qub txawm tias ntawm 900 ℃. Cov yam ntxwv no ua rau nws tsis tseem ceeb hauv cov ntawv thov uas xav tau kev tiv taus kub heev.

3) Kev Ruaj Ntseg Tshuaj Lom Zem: Tsis Txhob Ntshai Kev Ua Rau Ib puag ncig puas tsuaj

Cov fiber basalt tuaj yeem tiv taus ob qho tib si acid thiab alkali muaj zog. Nws cov kua qaub thiab alkali tsis kam zoo dua li cov txhuas borosilicate fibers, thiab nws cov khoom siv ruaj khov, tiv taus huab cua, tiv taus UV hluav taws xob, tiv taus dej, thiab tiv taus oxidation zoo ib yam li pob zeb basalt ntuj. Qhov no txhais tau tias nyob rau hauv ntau qhov chaw ntuj thiab tshuaj lom neeg, basalt fiber tuaj yeem ruaj khov thiab tiv taus kev yaig, ua kom ntseeg tau tias cov khoom siv siv nws mus sij hawm ntev.

4) Modulus Siab thiab Lub Zog Tensile Muaj Zog: Cov Khoom Siv Kho Tshuab Zoo Tshaj Plaws

Hais txog cov ntsuas kev ua tau zoo ntawm cov khoom siv kho tshuab, cov fiber basalt ua tau zoo heev. Nws cov elastic modulus yog txij li 85 GPa txog 110 GPa, siab dua li E-iav fiber, asbestos, aramid fiber, polypropylene fiber, thiab silica fiber. Nws lub zog tensile ncav cuag 3000-4800 MPa, dhau cov carbon fiber loj, aramid, PBI fiber, hlau fiber, boron fiber, thiab alumina fiber, thiab zoo ib yam li S-iav fiber. Cov khoom siv kho tshuab zoo heev no ua rau... basalt fiber ib qho kev txhawb nqa zoo tagnrho rau kev txhim kho cov khoom siv kho tshuab ntawm cov khoom sib xyaw, siv dav hauv cov teb uas xav tau cov ntaub ntawv muaj zog.

5) Kev Nqus Suab Zoo thiab Kev Txo Suab Nrov, Kev Ua Tau Zoo Tshaj Plaws

Cov fiber basalt muaj cov coefficient nqus suab siab txog li 0.9-0.99, uas siab dua li E-iav fiber thiab silica fiber, qhia tau tias muaj cov yam ntxwv zoo heev ntawm kev nqus suab thiab kev rwb thaiv tsev. Tib lub sijhawm, nws kuj muaj cov khoom pom tseeb zoo heev ntawm lub zog hluav taws xob thiab qee yam kev nqus nthwv dej. Cov yam ntxwv no muab nws qhov zoo tshwj xeeb hauv cov ntaub ntawv zais cia, ua tau raws li cov khoom siv tshwj xeeb ntawm kev tiv thaiv thiab tub rog thiab muab kev txhawb nqa zoo rau kev txhim kho kev ua haujlwm zais cia ntawm cov khoom siv cuam tshuam.

2. Kev siv Basalt Fiber hauv Low-Altitude Sector

1) Kev Tsim Khoom Siv Dav Hlau

Vim nws lub zog siab thiab qhov ceev qis, basalt fiber siv tau los tsim cov khoom xws li UAV fuselages, tis, thiab propellers. Qhov no txo ​​qhov hnyav ntawm UAV thaum ua kom muaj zog ntawm cov qauv, txhim kho nws lub zog thiab lub peev xwm thauj khoom, thiab txhim kho nws cov kev ua haujlwm zoo thiab kev ntseeg siab. Tsis tas li ntawd, basalt fiber tuaj yeem siv los tsim cov roj teeb UAV casings thiab sensor casings. Tsis tas li ntawd, UAVs yuav ntsib kev sib tsoo thiab khawb thaum lub sijhawm ya; basalt fiber qhov kev tiv thaiv kev hnav siab thiab kev cuam tshuam ua rau nws siv tau hauv kev tsim cov casings tiv thaiv lossis npog rau UAVs, yog li tiv thaiv cov khoom siv hluav taws xob sab hauv thiab cov qauv kho tshuab los ntawm kev cuam tshuam sab nraud.

2) Kev Tsim Kho Vaj Tse Hauv Qab Av Qis

Cov fiber basalt kuj ua lub luag haujlwm tseem ceeb hauv kev tsim kho vaj tse qis. Nws tuaj yeem sib xyaw nrog cov ntaub ntawv xws li pob zeb siv rau hauv kev tsim cov kev khiav ntawm tshav dav hlau thiab cov chaw nres tsheb. Kev ntxiv cov fiber basalt tuaj yeem ua rau lub neej ntev thiab lub peev xwm thauj khoom ntawm cov kev khiav thiab cov chaw nres tsheb, ua kom ntseeg tau tias kev ua haujlwm zoo thiab ruaj khov ntawm cov chaw tshav dav hlau. Piv txwv li, cov basalt fiber grids tuaj yeem siv rau kev txhawb nqa cov kev khiav ntawm tshav dav hlau. Hauv kev tsim cov pej thuam tswj hwm thiab cov chaw navigation, basalt fiber tuaj yeem siv los tsim cov khoom siv xws li cov pej thuam thiab cov kav hlau txais xov. Vim yog basalt fiber tiv taus cua zoo heev, nws tuaj yeem txhim kho qhov tiv taus cua thiab kev ruaj khov ntawm cov khoom siv no, ua kom ntseeg tau tias kev ua haujlwm ib txwm ntawm cov chaw navigation hauv cov huab cua nyuaj. Ntxiv mus, basalt fiber tsis yog conductive thiab muaj cov khoom nqus nthwv dej thiab pob tshab. Raws li cov yam ntxwv no, nws kuj qhia txog qee qhov peev xwm txhim kho hauv kev tsim kho UAV infrastructure, xws li radomes thiab 5G antenna npog.
