Lub elastic modulus ntawm aramid daim ntaub feem ntau yog nruab nrab ntawm 200-400 GPa, thiab cov nqi tshwj xeeb txawv nyob ntawm ntau yam thiab kev tsim khoom. Piv txwv li, lub elastic modulus ntawm ib co aramid daim ntaub yog hais txog 120 GPa.
Txhais thiab ntsuas txoj kev ntawm elastic modulus
Lub elastic modulus yog ib qho kev ntsuas ntawm cov khoom muaj peev xwm tiv thaiv deformation thaum raug rau sab nraud quab yuam. Rau aramid daim ntaub, nws elastic modulus hais txog qhov piv ntawm kev ntxhov siab rau strain nyob rau hauv lub elastic ntau yam ntawm cov khoom. Lub elastic modulus ntawm daim ntaub aramid feem ntau yog ntsuas los ntawm kev ntsuas tensile. Los ntawm ncab cov qauv ntaub aramid thiab sau nws cov elongation nyob rau hauv sib txawv tensile rog, qhov kev ntxhov siab-strain nkhaus yog tau. Lub elastic modulus yog txoj kab nqes ntawm txoj kab nkhaus hauv thawj kab ntu.
Cov yam ntxwv cuam tshuam rau elastic modulus
Lub elastic modulus ntawm aramid daim ntaub yog cuam tshuam los ntawm ntau yam, nrog rau hom fiber ntau, fiber ntau, cov ntsiab lus fiber ntau, thiab cov txheej txheem tsim khoom. Ntau hom fiber ntau thiab kev npaj cuam tshuam rau tag nrho cov khoom siv kho tshuab ntawm cov khoom siv, uas cuam tshuam rau elastic modulus. Tsis tas li ntawd, yam xws li qhov kub thiab txias hauv cov txheej txheem tsim khoom kuj tseem cuam tshuam rau elastic modulus ntawm aramid daim ntaub.
Daim ntawv thov teb ntawm aramid daim ntaub
Aramid daim ntaub yog dav siv nyob rau hauv ntau lub teb vim nws siab elastic modulus, siab zog thiab zoo tshav kub kuj. Hauv kev lag luam, cov ntaub aramid tuaj yeem siv los ua cov khaub ncaws tiv thaiv kub, cov ntaub thaiv hluav taws thiab lwm yam khoom. Hauv kev tsim kho, daim ntaub aramid tuaj yeem siv los txhawb cov vaj tse pob zeb thiab txhim kho cov seismic tsis kam ntawm cov tsev. Hauv thaj chaw aerospace, aramid daim ntaub tuaj yeem siv los tsim cov khoom siv ua haujlwm siab xws li dav hlau thiab foob pob hluav taws. Tsis tas li ntawd, aramid daim ntaub kuj muaj cov yam ntxwv ntawm cov tsis muaj conductivity, zoo corrosion kuj, thiab muaj zog tiv thaiv. Nws yog tsim rau kev txhawb nqa ntawm subways, tunnels, electrified railways thiab lwm yam dej num.
