Lub teeb yuag thiab siab zog
Cov txheeb ze ntom ntom yog nyob nruab nrab ntawm 1.5 ~ 2.0, uas tsuas yog 1/4 ~ 1/5 ntawm cov pa roj carbon steel, tab sis lub zog tensile nyob ze los yog siab tshaj ntawm cov hlau, thiab lub zog tshwj xeeb tuaj yeem muab piv nrog cov qib high-qib alloy steel. Yog li ntawd, nws tau ua tiav cov txiaj ntsig zoo tshaj plaws hauv aviation, foob pob hluav taws, lub dav hlau, cov hlab ntsha siab thiab lwm yam khoom uas yuav tsum tau txo tus kheej qhov hnyav. Lub tensile, dabtsi yog khoov thiab compressive zog ntawm ib co epoxy FRP tuaj yeem ncav cuag ntau tshaj 400MPa.
Corrosion kuj
FRP yog cov khoom siv zoo corrosion-resistant, uas muaj kev tiv thaiv zoo rau huab cua, dej, kua qaub, alkali, ntsev ntawm cov ntsiab lus dav dav, thiab ntau yam roj thiab cov kuab tshuaj. Nws tau siv rau txhua yam ntawm cov tshuaj tiv thaiv corrosion thiab hloov cov pa roj carbon steel, stainless hlau, ntoo, cov hlau tsis muaj hlau, thiab lwm yam.
Kev ua haujlwm hluav taws xob zoo
Nws yog ib qho zoo heev insulating khoom siv los ua insulators. Nws tseem tuaj yeem tiv thaiv cov cuab yeej zoo dielectric ntawm qhov siab. Microwave kis tau tus mob zoo thiab tau siv dav hauv radar radome.
Kev ua haujlwm zoo thermal
FRP muaj cov thermal conductivity tsawg, uas yog 1.25 ~ 1.67kj / (m · h · K) ntawm chav tsev kub, tsuas yog 1/100 ~ 1/1000 ntawm hlau. Nws yog cov khoom siv thermal rwb thaiv tsev zoo heev. Nws yog qhov zoo tshaj plaws thermal tiv thaiv thiab ablation resistant khoom nyob rau hauv cov ntaub ntawv ntawm instantaneous ultra-siab kub, thiab muaj peev xwm tiv thaiv spacecraft los ntawm high-ceev airflow yaig saum toj no 2000 degree
