Kevlar yog ib hom hluavtaws fiber ntau uas paub txog nws lub zog zoo kawg thiab ua haujlwm ntev. Nws tau tshaj tawm thawj zaug hauv xyoo 1970 los ntawm lub tuam txhab tshuaj DuPont, thiab txij li ntawd los tau siv dav hauv ntau yam kev siv, suav nrog lub cev armor rau tub ceev xwm thiab tub rog.
Cov lus nug ntawm yuav ua li cas tuab Kevlar yuav tsum tau nres ib lub mos txwv tsis yog ib qho yooj yim los teb. Qhov kev ua tau zoo ntawm Kevlar yog cov khoom siv phom sij yog nyob ntawm ntau yam, suav nrog hom mos txwv raug rho tawm haujlwm, qhov nrawm uas nws mus ncig, thiab qhov tuab thiab lub zog ntawm Kevlar fibers.
Feem ntau, Kevlar muaj txiaj ntsig zoo ntawm kev tso tseg feem ntau cov phom thiab phom phom, nrog rau qee qhov phom sij, nyob ntawm seb hom Kevlar tshwj xeeb thiab lub zog thiab tuab ntawm cov fibers. Txawm li cas los xij, tsis muaj cov khoom siv los tiv thaiv cov mos txwv, thiab ib txwm muaj kev pheej hmoo ntawm kev raug mob lossis tuag thaum lub mos txwv raug rho tawm haujlwm.
Muaj ntau ntau hom Kevlar fibers muaj nyob rau hauv kev ua lag luam niaj hnub no, txhua tus muaj lawv tus kheej lub zog thiab lub zog. Qee hom Kevlar feem ntau suav nrog Kevlar XP, Kevlar KM2, thiab Kevlar AP. Cov fibers no feem ntau siv rau ntau yam kev siv, nrog rau lub cev armor, kaus mom hlau, thiab tsheb armor.
Txhawm rau kom Kevlar ua haujlwm tau zoo ntawm kev txwv cov mos txwv, nws yuav tsum tau ua ke nrog lwm cov ntaub ntawv los tsim cov khoom sib xyaw uas tuaj yeem nqus tau thiab tawg lub zog ntawm cov mos txwv. Qhov no feem ntau ua tiav los ntawm kev tso ntau daim ntawv ntawm Kevlar rau ib leeg, nrog rau lwm cov ntaub ntawv xws li ceramic phaj, hlau, lossis lwm cov fibers muaj zog.
Thaum tsim cov mos txwv lub cev armor, nws yog ib qho tseem ceeb uas yuav tau xav txog cov kev xav tau tshwj xeeb ntawm tus neeg hnav. Qhov no yuav suav nrog hom haujlwm lossis kev ua haujlwm uas tus neeg hnav yuav koom nrog, nrog rau lawv tus kheej lub cev loj thiab cov duab.
