Lub teeb thiab siab -Lub zog
Nws qhov txheeb ze ntom ntom yog li ntawm 1.5 txog 2.0-tsuas yog ib qho -lub quarter rau ib- tsib ntawm cov pa roj carbon steel-tsis tau nws lub zog tensile mus txog, los yog ntau tshaj, ntawm cov hlau, thaum nws lub zog tshwj xeeb yog piv rau qib siab - qib alloy steels. Yog li ntawd, nws ua pov thawj muaj txiaj ntsig zoo hauv kev siv dav hlau, foob pob hluav taws, lub dav hlau, cov hlab ntsha siab, thiab lwm yam khoom uas txo qhov hnyav yog qhov tseem ceeb. Qee cov epoxy FRPs tuaj yeem ua tiav tensile, flexural, thiab compressive zog tshaj 400 MPa. Qhov ceev, lub zog, thiab qhov tshwj xeeb muaj zog qhov tseem ceeb rau cov ntaub ntawv xaiv tau nthuav tawm hauv Table 1-1.
Zoo heev Corrosion Resistance
FRP yog ib qho zoo heev corrosion-cov ntaub ntawv tiv taus, nthuav tawm muaj zog tiv thaiv huab cua, dej, acids, alkalis, ntsev (ntawm tus qauv concentration), nrog rau ntau yam roj thiab cov kuab tshuaj. Nws tau ua tiav nyob rau hauv tag nrho cov spectrum ntawm chemical corrosion- daim ntaub ntawv tiv thaiv, qhov uas nws yog nce hloov cov ntaub ntawv ib txwm muaj xws li carbon steel, stainless hlau, ntoo, thiab tsis yog - ferrous hlau.
Superior Electrical Properties
Nws ua haujlwm zoo li cov khoom siv hluav taws xob zoo heev thiab yog siv dav hauv kev tsim cov insulators. Nws khaws nws cov khoom zoo tshaj plaws dielectric txawm nyob rau ntawm qhov chaw siab. Tsis tas li ntawd, nws nthuav tawm cov pob tshab microwave zoo heev, ua rau nws siv dav hauv kev tsim kho ntawm radar radomes.
Zoo heev Thermal Properties
FRP muaj cov thermal conductivity tsawg-xws li ntawm 1.25 txog 1.67 kJ / (m·h·K) ntawm chav tsev kub -uas yog ib qho -pua pua rau ib- txhiab ntawm cov hlau; Yog li, nws ua haujlwm raws li cov khoom tshwj xeeb thermal rwb thaiv tsev. Hauv cov xwm txheej cuam tshuam nrog kev hloov pauv ultra- kub siab, nws ua haujlwm zoo tshaj plaws rau kev tiv thaiv thermal thiab ablation tsis kam, muaj peev xwm tiv thaiv lub dav hlau tiv thaiv lub zog erosive ntawm siab - nrawm airflow ntawm qhov kub siab tshaj 2000℃.
High Design Flexibility
① Nws tso cai rau kev hloov pauv ntawm ntau yam khoom tsim raws li cov kev xav tau tshwj xeeb thiab kev ua tau zoo, yog li ua kom tsim cov khoom lag luam nrog tshwj xeeb cov qauv kev ntseeg siab.
② Nws muaj ntau txoj kev xaiv cov khoom siv kom haum raws li cov khoom lag luam specifications -piv txwv li, ua rau kev tsim cov ntaub ntawv zoo rau kev tiv thaiv corrosion, tsis kam mus rau qhov kub thiab txias, tshwj xeeb tshaj yog muaj zog nyob rau hauv cov lus qhia tshwj xeeb, superior dielectric zog, thiab lwm yam.
Kev ua tau zoo heev
① Cov txheej txheem molding tuaj yeem xaiv tau yooj yim raws li cov khoom tsim, cov kev qhia tshwj xeeb, cov ntawv thov, thiab ntim ntau lawm.
② Cov txheej txheem tsim khoom yog ncaj nraim, feem ntau tso cai rau ib qho - kauj ruam molding; qhov no ua rau cov txiaj ntsig tseem ceeb ntawm kev lag luam, tshwj xeeb tshaj yog hais txog nws qhov kev ua tau zoo tshaj plaws rau cov khoom qis - cov khoom ntim nrog cov duab nyuaj uas tsis yooj yim rau kev siv cov txheej txheem ib txwm ua.
