U-Linry-uvulindlela kwintsimi yeemveliso ze-bulletproofs, ukudala i-first class yesayensi kunye neteknoloji yanamhlanje ishishini.
ISAYENSI KUNYE NE-TEKNOLOJIYA OKUSHA
I-helmet ye-ballistic i-helmet ye-tactical ephezulu-yomelele eyenziwe ngezinto ezikhethekileyo ezifana ne-Kevlar kunye ne-PE enokukhusela kwiimbumbulu ukuya kwinqanaba elithile.
Ukusetyenziswa kweepleyiti zeceramic kususela emva kowe-1918, emva kokuphela kweMfazwe Yehlabathi I, xa uColonel Newell Monroe Hopkins wafumanisa ukuba ukugquma isikrweqe sentsimbi ngeglaze yeceramic kuya kuluqinisa kakhulu ukhuseleko lwaso.
Xa kuthethwa ngeemveliso ezingangenwa bullet, siqale sicinge ngeevesti ezingangenwa bulletproof, amakhaka angangenwa bulletproof, afakele iimbumbulu nezinye izixhobo.
Ubunzima betyhubhu ephezulu kakhulu ukuya kuthi ga kwizigidi ezi-2, isalathiso sokunxiba sincinci, sisinika ukuxhathisa okuphezulu kakhulu kwi-sliding friction.
Nokuba ukusebenza kobulletproof sisalathiso sokuqala sokhuseleko.Uvavanyo lwenziwa kwilebhu ye-ballistic.
