Thaum nws los txog rau cov khoom siv tiv thaiv tus kheej, cov kaus mom hlau ballistic yog ib qho ntawm cov khoom siv tseem ceeb tshaj plaws rau cov tub rog, cov tub ceev xwm, thiab cov kws tshaj lij kev ruaj ntseg. Tab sis cov kaus mom hlau ballistic ua haujlwm li cas? Thiab dab tsi ua rau lawv muaj txiaj ntsig zoo hauv kev tiv thaiv tus neeg hnav ntawm kev hem thawj ballistic?
Cov kaus mom hlau ballistic yog tsim los nqus thiab faib lub zog ntawm cov khoom tawg, yog li txo qhov kev pheej hmoo ntawm kev raug mob taub hau. Cov ntaub ntawv tseem ceeb siv rau hauv cov kaus mom hlau no suav nrog cov fibers aramid (xws li Kevlar) thiab cov polyethylene ua tau zoo. Cov ntaub ntawv no paub txog lawv qhov sib piv ntawm lub zog thiab qhov hnyav, ua rau cov kaus mom hlau tsis hnyav tab sis ruaj khov heev.
Kev tsim lub kaus mom hlau ballistic muaj ntau txheej ntawm cov khoom siv siab heev no. Thaum lub mos txwv ntaus lub kaus mom hlau, txheej sab nraud yuav hloov pauv thaum raug ntaus, ua rau lub zog tawg mus rau thaj chaw loj dua. Cov txheej txheem no pab tiv thaiv kev nkag mus thiab txo qhov kev pheej hmoo ntawm kev raug mob los ntawm lub zog tsis raug. Txheej sab hauv ntxiv nqus lub zog, muab kev tiv thaiv ntxiv rau tus neeg hnav.
Ntxiv rau qhov tiv thaiv tau mos txwv, ntau lub kaus mom hlau niaj hnub no muaj cov yam ntxwv uas ua rau lawv ua haujlwm tau zoo dua. Cov yam ntxwv no suav nrog cov kab ke sib txuas lus, cov khoom siv pom kev hmo ntuj, thiab cov tshuab ua pa kom ntseeg tau tias xis nyob thaum siv ntev. Qee lub kaus mom hlau kuj tsim los kom sib xws nrog lub ntsej muag thiab lwm yam khoom siv tiv thaiv, muab kev tiv thaiv zoo hauv ntau qhov xwm txheej.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias txawm hais tias cov kaus mom hlau ballistic muaj kev tiv thaiv zoo, lawv tsis yog qhov tsis muaj kev phom sij. Qib kev tiv thaiv uas lub kaus mom hlau muab nyob ntawm qib kev hem thawj ballistic uas nws tuaj yeem tiv taus, thiab cov neeg siv yuav tsum paub txog qhov txwv ntawm lawv cov khoom siv. Kev saib xyuas tsis tu ncua thiab kev haum kom raug kuj tseem ceeb heev kom ntseeg tau tias muaj kev ua haujlwm zoo tshaj plaws.
Hauv kev xaus lus, cov kaus mom hlau ballistic yog ib feem tseem ceeb ntawm cov khoom siv tiv thaiv tus kheej, tsim los nqus thiab faib lub zog ntawm cov kev hem thawj ballistic. Kev nkag siab txog lawv ua haujlwm li cas tuaj yeem pab cov neeg siv txiav txim siab txog kev nyab xeeb thiab kev tiv thaiv hauv cov chaw muaj kev pheej hmoo siab.
