Hauv kev lag luam dav hlau, kev ua tau zoo ntawm cov ntaub ntawv muaj feem cuam tshuam ncaj qha rau kev ua tau zoo, kev nyab xeeb thiab kev txhim kho ntawm lub dav hlau. Nrog rau kev nce qib sai ntawm thev naus laus zis dav hlau, cov kev xav tau rau cov ntaub ntawv tau dhau los ua ntau dua thiab nruj dua, tsis yog tsuas yog muaj lub zog siab thiab qis qis, tab sis kuj tseem muaj kev tiv thaiv kub siab, kev tiv thaiv tshuaj lom neeg, kev rwb thaiv tsev hluav taws xob thiab cov khoom dielectric thiab lwm yam ntawm kev ua tau zoo heev.Cov fiber ntau quartzCov khoom sib xyaw ua ke silicone tau tshwm sim los ntawm qhov tshwm sim, thiab nrog lawv cov khoom sib xyaw ua ke, lawv tau dhau los ua lub zog tshiab hauv kev lag luam dav hlau, txhaj tshuaj tshiab rau hauv kev txhim kho cov tsheb dav hlau niaj hnub.

Kev kho ua ntej ntawm fiber ntau txhim kho kev sib txuas
Ua ntej yuav muab cov quartz fibers sib xyaw ua ke nrog silicone resin, kev kho ua ntej ntawm cov quartz fibers yog ib qho tseem ceeb heev. Vim tias qhov chaw ntawm cov quartz fibers feem ntau yog du, uas tsis zoo rau kev sib txuas nrog silicone resin, qhov chaw ntawm cov quartz fibers tuaj yeem hloov kho los ntawm kev kho tshuaj, kev kho plasma thiab lwm txoj kev.
Kev Tsim Cov Roj Hmab Uas Zoo Tshaj Plaws Rau Kev Ua Tau Raws Li Qhov Xav Tau
Cov silicone resins yuav tsum tau ua kom raug kom ua tau raws li ntau yam kev xav tau ntawm cov khoom sib xyaw ua ke ntawm ntau yam kev siv hauv kev lag luam aerospace. Qhov no suav nrog kev tsim qauv thiab kev kho kom zoo ntawm cov qauv molecular ntawm cov silicone resin, nrog rau kev ntxiv cov tshuaj kho, cov tshuaj catalysts, cov khoom sau thiab lwm yam khoom ntxiv.
Ntau Txoj Kev Moulding kom Paub Tseeb Zoo
Cov txheej txheem molding rau cov khoom siv quartz fiber silicone suav nrog Resin Transfer Molding (RTM), Vacuum Assisted Resin Injection (VARI), thiab Hot Press Molding, txhua tus muaj nws tus kheej cov txiaj ntsig tshwj xeeb thiab qhov ntau thiab tsawg ntawm daim ntawv thov.
Resin Transfer Molding (RTM) yog ib qho txheej txheem uas cov khoom siv kho ua ntej lawmcov fiber quartzCov preform tau muab tso rau hauv pwm, thiab tom qab ntawd cov silicone resin uas tau npaj tseg tau txhaj rau hauv pwm hauv qab lub tshuab nqus tsev kom nkag mus rau hauv cov fiber nrog cov resin, thiab tom qab ntawd thaum kawg kho thiab pwm hauv qab qee qhov kub thiab siab.
Cov txheej txheem txhaj tshuaj resin uas siv lub tshuab nqus tsev, ntawm qhov tod tes, siv lub tshuab nqus tsev los rub cov resin rau hauv cov pwm uas muaj cov fibers quartz kom paub txog cov fibers thiab resin sib xyaw.
Cov txheej txheem molding kub yog sib tov cov fibers quartz thiab silicone resin hauv ib qho kev faib ua feem, muab tso rau hauv pwm, thiab tom qab ntawd ua kom cov resin kho hauv qab qhov kub thiab siab, yog li tsim cov khoom sib xyaw.
Kev kho tom qab kom ua kom cov khoom siv zoo dua
Tom qab cov khoom sib xyaw ua pwm lawm, yuav tsum muaj ntau yam txheej txheem kho tom qab, xws li kev kho cua sov thiab kev siv tshuab, los txhim kho cov khoom siv thiab ua kom tau raws li cov kev cai nruj ntawm thaj chaw dav hlau. Kev kho cua sov tuaj yeem tshem tawm cov kev ntxhov siab seem hauv cov khoom sib xyaw, txhim kho kev sib txuas ntawm cov fiber thiab matrix, thiab txhim kho kev ruaj khov thiab kev ua haujlwm ntev ntawm cov khoom. Los ntawm kev tswj hwm cov kev cai ntawm kev kho cua sov xws li kub, sijhawm thiab tus nqi txias, kev ua tau zoo ntawm cov khoom sib xyaw tuaj yeem ua kom zoo dua.
Kev Ua Tau Zoo Dua:

Lub Zog Tshwj Xeeb Siab thiab Kev Txo Qhov Hnyav Modulus Tshwj Xeeb Siab
Piv nrog cov ntaub ntawv hlau ib txwm muaj, cov khoom sib xyaw ua los ntawm cov khoom siv silicone fiber ntau muaj qhov zoo ntawm lub zog tshwj xeeb (piv ntawm lub zog rau qhov ceev) thiab cov qauv tshwj xeeb siab (piv ntawm modulus rau qhov ceev). Hauv kev tsav dav hlau, qhov hnyav ntawm lub tsheb yog ib qho ntawm cov yam tseem ceeb uas cuam tshuam rau nws qhov kev ua tau zoo. Kev txo qhov hnyav txhais tau tias kev siv zog tuaj yeem txo qis, kev ya dav hlau nce ntxiv, ntau yam thiab qhov hnyav nce ntxiv. Kev siv ntawmcov fiber quartzCov khoom sib xyaw ua los ntawm silicone resin los tsim cov dav hlau fuselage, tis, tus tw thiab lwm yam khoom siv hauv cov qauv tuaj yeem txo qhov hnyav ntawm lub dav hlau raws li lub hauv paus ntawm kev ua kom muaj zog thiab kev tawv.

Cov khoom dielectric zoo los xyuas kom meej kev sib txuas lus thiab kev taw qhia
Hauv kev siv tshuab dav hlau niaj hnub no, kev ntseeg tau ntawm kev sib txuas lus thiab kev navigation systems yog qhov tseem ceeb heev. Nrog nws cov khoom dielectric zoo, cov khoom siv quartz fiber silicone composite tau dhau los ua cov khoom siv zoo tshaj plaws rau kev tsim cov dav hlau radome, lub kav hlau txais xov thiab lwm yam khoom. Radomes yuav tsum tiv thaiv lub kav hlau txais xov radar los ntawm ib puag ncig sab nraud thiab tib lub sijhawm xyuas kom meej tias cov nthwv dej electromagnetic tuaj yeem nkag mus tau zoo thiab raug xa cov teeb liab. Cov yam ntxwv dielectric qis thiab qis tangent poob ntawm cov khoom sib xyaw quartz fiber silicone tuaj yeem txo qhov poob thiab kev cuam tshuam ntawm cov nthwv dej electromagnetic hauv cov txheej txheem kis, xyuas kom meej tias lub kaw lus radar ntes tau lub hom phiaj thiab coj lub dav hlau ya.
Kev tiv thaiv ablation rau qhov chaw kub heev
Hauv qee qhov tshwj xeeb ntawm lub dav hlau, xws li lub chamber combustion thiab nozzle ntawm lub cav aviation, thiab lwm yam, lawv yuav tsum tiv taus qhov kub thiab txias heev thiab roj flushing. Quartz fiber silicone composites qhia tau zoo heev ablation tsis kam nyob rau hauv qhov chaw kub siab. Thaum qhov chaw ntawm cov khoom raug rau qhov kub thiab txias kub, cov silicone resin yuav decompose thiab carbonize, tsim ib txheej ntawm carbonized txheej nrog cov nyhuv rwb thaiv tsev kub, thaum cov quartz fibers muaj peev xwm tswj tau qhov kev ua tiav ntawm cov qauv thiab txuas ntxiv muab kev txhawb nqa lub zog rau cov khoom.

Cov Cheeb Tsam ntawm Daim Ntawv Thov:
Kev Tsim Kho Dua Tshiab ntawm Fuselage thiab Wing
Cov khoom siv sib xyaw ua ke ntawm quartz fiber siliconetab tom hloov cov hlau ib txwm muaj hauv kev tsim cov fuselages thiab tis ntawm lub dav hlau, ua rau muaj kev hloov pauv tseem ceeb ntawm cov qauv. Cov thav duab fuselage thiab tis girders ua los ntawm cov composites no muab kev txo qhov hnyav tseem ceeb thaum tseem tswj tau lub zog thiab kev tawv.
Kev kho kom zoo dua ntawm cov khoom siv aero-engine
Aero-engine yog lub hauv paus tseem ceeb ntawm lub dav hlau, thiab nws txoj kev txhim kho kev ua tau zoo yog qhov tseem ceeb rau kev ua tau zoo ntawm lub dav hlau. Cov khoom sib xyaw ua los ntawm cov roj hmab quartz fiber tau siv rau hauv ntau qhov chaw ntawm aero-engine kom ua tiav kev txhim kho thiab kev ua tau zoo ntawm cov khoom. Hauv cov khoom kub ntawm lub cav, xws li chav sib xyaw thiab cov hniav turbine, cov khoom sib xyaw ua ke qhov kub siab thiab kev tiv thaiv kev sib txhuam tuaj yeem txhim kho lub neej kev pabcuam thiab kev ntseeg siab ntawm cov khoom, thiab txo cov nqi kho ntawm lub cav.
