I-Aramid 1414 filament iyinhlanganisela yezinto ezakhiwe futhi zakhiwe yiDuPont Company ngo-1965. Ihlanganisa izici ezinhle kakhulu zamandla aphezulu nesisindo esincane.Ngaphansi kwesimo esifanayo sesisindo, iqine izikhathi ezingu-5 njengocingo lwensimbi, iqine izikhathi ezingu-2.5 njengefayibha yengilazi ye-E futhi iqine izikhathi ezingu-10 njenge-aluminium.Ibhekwa njengefayibha enamandla kunazo zonke emhlabeni, futhi isetshenziselwa ukulwa nomlilo, imboni yezempi, ukuphepha, ukuxhumana, ukuqinisa kanye neminye imikhakha.Kusukela lapho, i-China, Japan kanye neNingizimu Korea ziye zathuthuka futhi zakhiqiza ngokulandelana.Nakuba intengo inokuncintisana kakhulu, ikhwalithi nokusebenza kukude komunye nomunye.Ukumelana nokushisa okuhle kakhulu, i-Kevlar inokuqina okuphezulu ekusebenzeni kwezinga lokushisa.Ngeke isetshenziswe kuphela ngokuqhubekayo ebangeni lokushisa elingu--196 ℃ kuya ku-204 ℃ ngaphandle koshintsho olusobala noma ukulahlekelwa, kodwa futhi inokunganyibiliki futhi akukho okusekela ukuvutha (ukumelana nomlilo).Iqala kuphela ukwenza i-carbonize ku-427 ℃, futhi ngisho nasezingeni eliphansi lokushisa -196 ℃, akukho ukulahlekelwa kwe-embrittlement kanye nokusebenza, futhi ingabekezelela amazinga okushisa aphakeme kakhulu.
