Bulletproof khoom yog ib yam khoom tshwj xeeb uas muaj kev ua tau zoo ntawm cov mos txwv. Nws lub hauv paus ntsiab lus yog ua raws li kev paub txog physics thiab cov ntaub ntawv tshawb fawb, thiab los ntawm cov khoom siv sib xyaw ua ke thiab cov qauv tsim, nws tuaj yeem tiv thaiv kev nkag mus ntawm cov mos txwv los yog lwm yam khoom siv high-speed.
Lub hauv paus ntsiab lus tseem ceeb ntawm cov ntaub ntawv mos mos yog txo cov phom sij rau tib neeg lub cev los ntawm kev nqus, dispersion, thiab kev xav. Hauv kev tsim cov khoom siv, cov txheej txheem sib xyaw ua ke feem ntau yog siv, txhua txheej muaj cov yam ntxwv sib txawv thiab ua haujlwm.
Cov txheej txheem ntawm cov mos txwv sab nrauv feem ntau yog tsim los ntawm cov ntaub ntawv nyuaj, xws li ceramics, steel phaj, thiab lwm yam. Cov ntaub ntawv nyuaj no tuaj yeem cuam tshuam lub zog ntawm cov mos txwv, ua rau lawv deform lossis tawg thaum nkag mus, yog li txo qhov kev puas tsuaj rau cov ntaub so ntswg.
Cov txheej txheem nruab nrab ntawm cov ntaub ntawv mos txwv feem ntau yog tsim los ntawm cov ntaub ntawv polymer, xws li polyethylene fibers, aramid fibers, thiab lwm yam. Cov ntaub ntawv polymer no muaj lub zog tensile siab thiab tawv, uas tuaj yeem nqus tau lub zog ntawm cov mos txwv thiab tawg mus thoob plaws hauv cov khoom, yog li txo kev puas tsuaj. rau tib neeg lub cev.
Cov txheej sab hauv ntawm cov khoom siv phom sij feem ntau yog tsim los ntawm cov ntaub ntawv mos, xws li polyurethane ua npuas ncauj, gel, thiab lwm yam. Cov ntaub ntawv mos no tuaj yeem nqus tau lub zog ntawm cov mos txwv thiab hloov mus rau hauv thermal lossis mechanical zog, yog li txo qis kev puas tsuaj rau tib neeg lub cev. .
Ntxiv nrog rau kev sib xyaw ua ke ntawm cov ntaub ntawv thiab cov qauv tsim, cov tuab ntawm cov ntaub ntawv mos mos kuj yog qhov tseem ceeb cuam tshuam rau lawv cov kev tiv thaiv kev ua haujlwm. Feem ntau hais lus, lub thicker cov ntaub ntawv mos mos, qhov zoo dua nws elastic kuj. Txawm li cas los xij, vim qhov xav tau ntawm daim ntawv thov, lub thickness ntawm cov ntaub ntawv mos mos feem ntau yuav tsum tau muaj kev cuam tshuam nyob rau hauv ib qho chaw kom sib npaug tiv thaiv kev ua tau zoo thiab hnav kev nplij siab.
Cov txheej txheem kev npaj ntawm cov ntaub ntawv mos mos kuj yog ib qho tseem ceeb cuam tshuam rau lawv cov kev ua tau zoo. Kev ua haujlwm tsis raug thaum lub sijhawm npaj los yog teeb meem ntawm cov khoom siv tsis zoo tuaj yeem ua rau txo qis ntawm cov khoom siv phom sij. Yog li ntawd, nruj tswj hwm ntawm ntau yam txheej txheem tsis thiab nruj kev soj ntsuam ntawm cov ntaub ntawv yuav tsum tau thaum lub sij hawm kev npaj.
Cov ntaub ntawv mos mos tau siv dav hauv kev ua tub rog, tub ceev xwm, thiab kev ruaj ntseg. Los ntawm kev siv lub hauv paus ntsiab lus ntawm physics thiab cov ntaub ntawv tshawb fawb, cov ntaub ntawv mos mos tuaj yeem tiv thaiv tib neeg lub cev los ntawm cov khoom siv ceev ceev. Nrog rau kev txhim kho txuas ntxiv ntawm thev naus laus zis, kev ua tau zoo ntawm cov ntaub ntawv mos txwv kuj tseem txhim kho tas li, muab kev tiv thaiv zoo dua rau tib neeg lub neej kev nyab xeeb.
Hauv cov ntsiab lus, lub hauv paus ntsiab lus ntawm cov ntaub ntawv mos mos yog tsim los ntawm kev nqus, dispersion, thiab kev xav kom txo tau cov phom sij rau tib neeg lub cev. Los ntawm cov khoom siv sib xyaw ua ke thiab cov qauv tsim, cov ntaub ntawv mos mos tuaj yeem tiv thaiv kev nkag mus ntawm cov khoom siv ceev thiab tiv thaiv tib neeg lub cev los ntawm kev puas tsuaj. Nrog rau kev nce qib ntawm kev siv thev naus laus zis, kev ua haujlwm ntawm cov khoom siv phom sij yuav txuas ntxiv txhim kho, ua kom muaj txiaj ntsig ntau dua rau tib neeg txoj kev nyab xeeb lub neej.
