Tag nrho lub npe ntawm Aramid fiber yog "aromatic polyamide fiber", thiab lus Askiv lub npe yog Aramid fiber (DuPont cov khoom npe Kevlar yog ib hom aramid fiber, uas yog para-aramid fiber), uas yog ib qho tshiab high-tech hluavtaws fiber. Nrog ultra-siab zog, siab modulus thiab kub tsis kam, acid thiab alkali tsis kam, lub teeb yuag thiab lwm yam kev ua tau zoo, nws lub zog yog 5 ~ 6 zaug ntawm steel hlau, modulus yog 2 ~ 3 zaug ntawm steel hlau los yog iav fiber ntau, toughness yog 2 zaug ntawm steel hlau, thiab qhov hnyav tsuas yog li 1/5 ntawm steel hlau, ntawm 560 degrees ntawm kub, tsis decomposition. Nws muaj cov rwb thaiv tsev zoo thiab tiv thaiv kev laus, thiab muaj lub neej ntev. Kev tshawb pom ntawm aramid yog suav tias yog txheej txheem keeb kwm tseem ceeb hauv ntiaj teb cov ntaub ntawv.
