Lub teeb yuag thiab siab zog
Nws qhov txheeb ze qhov sib txawv ntawm 1.5 thiab 2.0-tsuas yog ib qho -quarter rau ib- tsib ntawm cov pa roj carbon steel-tsis tau nws lub zog tensile mus txog, los yog ntau tshaj, cov pa roj carbon steel. Tsis tas li ntawd, nws lub zog tshwj xeeb yog piv rau cov qib siab - alloy steels. Yog li ntawd, nws qhia tau hais tias muaj txiaj ntsig tshwj xeeb hauv cov ntawv thov kom txo qhov hnyav, xws li hauv dav hlau, foob pob hluav taws, lub dav hlau, cov hlab ntsha siab, thiab ntau yam khoom siv. Lub tensile, flexural, thiab compressive zog ntawm qee yam epoxy FRPs tuaj yeem tshaj 400 MPa.
Corrosion Resistance
FRP yog ib qho zoo heev corrosion- cov khoom siv tiv taus, pom muaj zog tiv thaiv huab cua, dej, thiab acids, alkalis, ntsev, thiab ntau yam roj thiab cov kuab tshuaj ntawm cov concentrations. Nws tau raug siv thoob plaws tag nrho cov spectrum ntawm tshuaj tiv thaiv corrosion thiab tam sim no hloov cov khoom siv xws li carbon steel, stainless hlau, ntoo, thiab tsis yog - ferrous hlau.
Cov khoom siv hluav taws xob zoo heev
Nws ua haujlwm zoo li cov khoom siv insulating zoo heev thiab siv dav hauv kev tsim cov insulators. Nws tuav zoo heev dielectric zog txawm nyob rau hauv high zaus. Tsis tas li ntawd, nws muaj qhov zoo tshaj plaws microwave pob tshab, ua rau nws siv dav hauv radar radomes.
Zoo heev Thermal Properties
FRP nthuav tawm cov thermal conductivity tsawg-xws li ntawm 1.25 txog 1.67 kJ/(m·h·K) ntawm chav sov-uas yog ib qho -pua pua rau ib- txhiab tus ntawm cov hlau; Yog li, nws ua haujlwm raws li cov khoom siv thermal rwb thaiv tsev zoo heev. Nyob rau hauv tej yam kev mob ntawm instantaneous, ultra- kub kub, nws ua hauj lwm raws li ib tug zoo tagnrho cov ntaub ntawv rau thermal tiv thaiv thiab ablation tsis kam, muaj peev xwm ntawm shielding spacecraft tiv thaiv erosive rog ntawm siab - ceev airflow ntawm kub tshaj 2000℃.
