Muaj ntau qhov tseeb tau ua pov thawj tias kev siv cov tsho tiv thaiv mos txwv tuaj yeem txo cov tub rog raug mob hauv kev ua tsov rog. Ntxiv rau, hauv qee lub tebchaws, kev ruaj ntseg hauv zej zog tsis zoo thiab muaj ntau qhov xwm txheej ua phem. Kev tiv thaiv tus kheej ntawm kev raug mob yog qhov tseem ceeb rau cov tub ceev xwm thiab txawm tias cov pej xeem ib txwm. Vim li no, ntau lub tebchaws tau pib tshawb fawb txog cov ntaub ntawv tiv thaiv mos txwv thiab cov tsho tiv thaiv ntev heev. Thaum Tsov Rog Thoob Ntiaj Teb Zaum Ib, cov hlau phaj tau siv rau kev tiv thaiv tib neeg, thiab tom qab ntawd kev tshawb fawb tau ua rau kev siv cov hlau xws li txhuas thiab titanium. Txawm li cas los xij, ntawm thaj chaw sib ntaus sib tua, cov tub rog yuav tsum tswj kev txav mus los. Vim yog qhov tuab ntawm cov hlau thiab nws qhov kev ua haujlwm tiv thaiv mos txwv tsis zoo, tib neeg pib kawm lwm yam khoom siv kom ua tiav cov teebmeem tiv thaiv mos txwv zoo dua. Yog li ntawd, tom qab Tsov Rog Thoob Ntiaj Teb Zaum Ob, cov tsho tiv thaiv mos txwv tau dhau los ua cov khaub ncaws tiv thaiv zoo tiv thaiv ntau yam ballistic projectiles. Tam sim no, nws tau dhau los ua cov khoom siv tiv thaiv tseem ceeb thiab tseem ceeb rau cov tub rog thiab tub ceev xwm. Tib lub sijhawm, kev tsim cov ntaub ntawv tiv thaiv mos txwv tau muaj txiaj ntsig zoo thiab tsim kho sai hauv cov tebchaws thoob ntiaj teb. Ntau hom khaub ncaws tiv thaiv mos txwv tshiab tau kawm tas li thiab tsim kho kom zoo.

Tam sim no, cov tsho tiv thaiv mos txwv feem ntau yog siv rau ob hom kev tiv thaiv. Ib qho yog cov mos txwv los ntawm rab phom thiab rab phom ntev, thiab lwm qhov yog cov khoom tawg los ntawm kev tawg.

Lub hauv paus ntsiab lus ntawm cov tsho tiv thaiv mos mos feem ntau yog siv feem ntau ntawm lub zog ntawm lub taub hau mos txwv (lossis cov khoom tawg) thaum lub sijhawm ncab, txiav, thiab ua rau cov fibers mos txwv puas tsuaj, ua rau lub taub hau mos txwv deform thiab deflect. Tib lub sijhawm, ib feem ntawm lub zog hloov mus ua lub zog thermal thiab suab, thaum lwm feem ntawm lub zog kis tau los ntawm cov fibers mus rau thaj chaw sab nraum qhov chaw cuam tshuam, thaum kawg qhwv lub taub hau mos txwv uas tau siv nws "lub zog" hauv txheej mos txwv. Thaum lub zog ntawm cov fibers mos txwv tsis txaus los tiv thaiv cov mos txwv tuaj, tib txoj kev yog siv "composite" daim ntawv ntawm cov khoom mos txwv mos txwv thiab tawv, uas yog, ntxiv cov hlau tawv, ceramic lossis cov khoom sib xyaw rau hauv cov tsho tiv thaiv mos txwv mos txwv, kev koom ua ke ntawm cov txheej txheem mos txwv ntawm cov khoom mos txwv thiab tawv ua ke: lub mos txwv thawj zaug sib cuag nrog cov ntxig tawv ua "kab thawj zaug ntawm kev tiv thaiv", thiab thaum lub sijhawm "kev sib tsoo nyuaj", lub mos txwv thiab cov khoom siv mos txwv tawv tuaj yeem deform thiab tawg, yog li siv feem ntau ntawm lub zog ntawm lub mos txwv. Cov ntaub mos mos uas tiv taus mos txwv xws li cov fibers tiv taus mos txwv ua haujlwm ua "kab thib ob ntawm kev tiv thaiv", nqus thiab faib cov zog seem ntawm lub mos txwv thiab ua lub luag haujlwm buffering, thiab thaum kawg, Ua tiav cov nyhuv tiv taus mos txwv. Cov tsho tiv thaiv mos txwv tawv yog cov khoom thaum ntxov uas tsuas yog siv cov ntaub tawv tiv taus mos txwv xws li cov phaj hlau rau kev tiv thaiv, ua rau tsis xis nyob thiab tsis muaj txiaj ntsig zoo rau kev tiv thaiv. Tam sim no lawv tau raug tshem tawm ntau zaus.
