Cov ntaub thaiv uas tiv thaiv tau mos txwv tsis yog cov khoom siv ua yeeb yaj kiab xwb—lawv yog cov khoom siv tiv thaiv tseem ceeb rau cov tub rog niaj hnub no, tub ceev xwm, thiab cov haujlwm ruaj ntseg. Muaj peev xwm tiv taus cov kev hem thawj xws li cov mos txwv thiab cov khoom tawg, lawv siv dav hauv kev tawm tsam kev ua phem, kev coj mus, thiab lwm yam xwm txheej muaj kev pheej hmoo siab. Cov khoom tsim nyog yuav tsum dhau daim ntawv pov thawj xeem ballistic.
Raws li daim ntawv, cov ntaub thaiv mos txwv feem ntau poob rau hauv ob pawg: cov qauv tuav tes (yoog tau thiab nqa tau, tsim nyog rau kev ua haujlwm ib leeg) thiab cov qauv log (qib kev tiv thaiv siab, zoo tagnrho rau kev tiv thaiv ua ke). Qee qhov kev tsim tshwj xeeb ntxiv txhim kho kev ywj pheej ua haujlwm.
Lub hauv paus ntawm lawv lub peev xwm tiv thaiv yog nyob rau hauv cov ntaub ntawv: Cov hlau nplaum muaj zog sib npaug qhov nyuaj thiab kev tiv thaiv corrosion; cov khoom siv ceramics tsis muaj mos txwv nqus cov zog kinetic ntawm cov mos txwv los ntawm lawv tus kheej fragmentation, xa cov kev ua tau zoo tiv thaiv; ultra-high molecular weight polyethylene (UHMWPE) muaj qhov zoo ntawm qhov hnyav sib dua thiab lub zog siab, ua rau cov ntaub thaiv yooj yim dua. Tsis tas li ntawd, qhov chaw tiv thaiv feem ntau yog npog nrog PU txheej lossis ntaub rau kev tiv thaiv dej, tiv thaiv UV, thiab tiv thaiv blunting. Lub qhov rais iav soj ntsuam mos txwv ua kom pom tseeb rau cov neeg siv thaum nyob hauv kev tiv thaiv. Cov qauv siab kawg kuj tseem tuaj yeem koom ua ke lub teeb pom kev zoo thiab kev sib txuas lus kom txhim kho kev hloov pauv ntawm lub luag haujlwm.
Seb lub tiv thaiv mos txwv puas tuaj yeem tiv thaiv cov mos txwv nyob ntawm nws qib kev tiv thaiv. Cov khoom lag luam ib txwm yuav tsum dhau los ntawm kev sim ballistic los ntawm cov neeg sab nraud, thiab qib ntawv pov thawj txiav txim siab hom mos txwv uas nws tuaj yeem tiv taus (piv txwv li, cov mos txwv phom, cov mos txwv phom). Tsuav koj xaiv cov khoom lag luam uas tau ntawv pov thawj nrog qib tsim nyog raws li qhov xav tau tiag tiag, koj tuaj yeem tau txais kev tiv thaiv txhim khu kev qha.
Hauv kev xaus lus, cov ntaub thaiv tiv thaiv mos txwv yog cov khoom siv tiv thaiv tiag tiag thiab zoo. Kev xaiv cov khoom lag luam uas tau ntawv pov thawj raug cai yog qhov tseem ceeb rau kev ua kom muaj kev tiv thaiv kev ruaj ntseg.
