High- qib kev tiv thaiv: Cov ris tsho hnav ris tsho yog ua los ntawm siab -kev ua haujlwm engineering yas thiab siab -molecular- hnyav polyethylene tsis- cov ntaub fibers, muab cov stab thiab cuam tshuam zoo. Nws tuaj yeem tiv taus 20 joules ntawm kinetic zog puncture, kom ntseeg tau tias cov hniav tsis tuaj yeem nkag mus rau txheej tiv thaiv; tib lub sijhawm, nws tuaj yeem tiv taus 120 joules ntawm lub zog kinetic cuam tshuam, lav cov txheej tiv thaiv tseem tsis raug.
Kev tiv thaiv kev nyab xeeb: Cov khaub ncaws kub kub muab ntau tshaj 1.2 square metres ntawm kev tiv thaiv, npog tag nrho cov neeg hnav lub cev tseem ceeb, suav nrog lub taub hau (feem ntau siv nrog lub kaus mom hlau), lub cev, thiab ceg ceg. Tsis tas li ntawd, cov caj npab thiab ceg tiv thaiv muaj ob npaug - txheej tiv thaiv, ntxiv dag zog rau kev tiv thaiv.
Yooj yim thiab ruaj khov: Thaum muab kev tiv thaiv muaj zog, lub tsho tiv thaiv kuj tseem tsim nrog kev nplij siab hauv siab. Los ntawm kev tsim qauv tsim qauv thiab xaiv cov khoom siv, lub tsho tiv no txo cov neeg hnav lub nra thiab txhim kho kev nplij siab thaum hnav ntev thaum tswj kev tiv thaiv zoo. High - cov ntaub ntawv ua tau zoo kuj ua kom cov khaub ncaws ua kom ntev thiab ua neej nyob.
Kev tiv thaiv hluav taws zoo heev: Lub foob pob hluav taws ua tiav qhov FV-5 qhov hluav taws kub tiv thaiv, tswj kev ruaj ntseg hauv ib puag ncig nrog tsawg kawg 28% oxygen. Qhov tshwj xeeb no tso cai rau cov iav kev kub ntxhov los muab kev tiv thaiv zoo rau cov neeg hnav txawm tias nyob hauv ib puag ncig huab cua xws li hluav taws kub.
Kev sib tw siab: Riot iav yog tsim rau cov tib neeg siab dua 175cm thiab hnyav kwv yees li 6kg (qhov hnyav tiag tiag yuav txawv nyob ntawm hom thiab qauv). Nws tsim nyog tsim ua rau nws yooj yim rau hnav thiab yoog raws ntau qhov chaw ib puag ncig thiab lub hom phiaj xav tau.
