Aramid 1414 filament yog cov khoom sib xyaw tsim thiab tsim los ntawm DuPont Tuam Txhab hauv xyoo 1965. Nws muab cov yam ntxwv zoo heev ntawm lub zog siab thiab lub teeb yuag.Nyob rau hauv tib lub cev hnyav, nws yog 5 npaug zog li steel hlau, 2.5 npaug zog li E-qib iav fiber ntau thiab 10 npaug zog li txhuas.Nws yog suav hais tias yog lub zog fiber ntau hauv ntiaj teb, thiab yog dav siv hauv kev tua hluav taws, kev lag luam tub rog, kev ruaj ntseg, kev sib txuas lus, kev txhawb zog thiab lwm yam kev lag luam.Txij thaum ntawd los, Tuam Tshoj, Nyiv thiab Kaus Lim Qab Teb tau txuas ntxiv tsim thiab tsim tawm.Txawm hais tias tus nqi sib tw heev, qhov zoo thiab kev ua tau zoo nyob deb ntawm ib leeg.Kev ntsuas kub zoo heev, Kevlar muaj kev ruaj ntseg hauv kev ua haujlwm kub.Nws tsis tuaj yeem siv tsis tu ncua nyob rau hauv qhov kub ntawm -196 ℃ to 204 ℃ yam tsis muaj kev hloov pauv lossis poob, tab sis kuj muaj insolubility thiab tsis muaj combustion-txhawb (hluav taws kub).Nws tsuas yog pib carbonize ntawm 427 ℃, thiab txawm tias qhov kub ntawm -196 ℃, tsis muaj embrittlement thiab kev ua haujlwm poob, thiab nws tuaj yeem tiv taus kub li siab.
