Kwindawo yanamhlanje ekhethekileyo yamazwe ngamazwe, ipleyiti ye-Bulletproof (okanye iithayile ze-bulletproof) zixatyiswa kakhulu ngabantu, kodwa kwimarike yepleyiti ye-bulletproof inezinto ezininzi, umahluko wokusebenza mkhulu kakhulu, ngokwezinto ezibonakalayo, inkqubo kunye nezinye iipleyiti ze-bulletproof eziqhelekileyo zingahlulwa zibe ziindidi ezintathu, ezizezi: ipleyiti ye-bulletproof yentsimbi, ipleyiti ye-polyethylene PE bulletproof kunye nepleyiti ye-ceramic bulletproof, iintlobo ezintathu zepleyiti nganye ineengenelo kunye neengxaki, ukhetho lukwafuna ukuqwalaselwa ngokubanzi. Khetha ipleyiti ye-bulletproof, kufuneka ugxile kwiimpawu ezintathu: ubunzima, ixabiso kunye nokukwazi kwe-bulletproof (oko kukuthi inqanaba le-bulletproof), namhlanje sivela kwezi nkalo zintathu zeentlobo ezintathu zohlalutyo kunye nokuthelekisa ipleyiti ye-bulletproof.
1. Ipleyiti yentsimbi engangeni mbumbulu
Ipleyiti yentsimbi engangenisi mbumbulu ibisetyenziswa ukusukela kwiMfazwe Yehlabathi yesiBini kwaye yayilawula imarike engangenisi mbumbulu kwiminyaka emininzi eyadlulayo. Kodwa emva kokuphuhliswa kwepleyiti ye-polyethylene PE engangenisi mbumbulu kunye nepleyiti ye-ceramic engangenisi mbumbulu, ipleyiti yentsimbi engangenisi mbumbulu yatshintshwa kancinci kancinci. Zisasetyenziswa nanamhlanje, kodwa ngamanani amancinci.
Xa kuthelekiswa nepleyiti entsha engangeni mbumbulu, ipleyiti yentsimbi engangeni mbumbulu kulula ukuyiqhekeza emva kokuba idutyulwe, nto leyo eya kubangela umonakalo wesibini emzimbeni womntu. Xa kuthelekiswa nezinye izinto ezimbini, ipleyiti yentsimbi engangeni mbumbulu enomgangatho ofanayo wokhuseleko inzima, idla amandla amaninzi kwaye inciphisa ukuguquguquka komntu oyinxibileyo.
Nangona ipleyiti yentsimbi engangenisi bullet yeyona iphantsi kwii-insert ezintathu, kodwa iyonke, ayikhuthazwa njengokhetho lokuqala.
2. Ipleyiti ye-polyethylene PE engenazimbumbulu
I-Polyethylene PE luhlobo olutsha lwezinto ezisetyenziswa kwi-thermoplastic. Ipleyiti ye-Polyethylene PE engenazimbumbulu yenziwe ngokubopha imicu ye-polyethylene enobunzima obuphezulu obuphezulu kwibhodi ye-polyethylene enobunzima obuphezulu. Inqunyulwa ibe yimo, ibekwe kwi-mold, ize icinezelwe phantsi kobushushu obuphezulu kunye noxinzelelo ukuze kufunyanwe ipleyiti ye-armor eqinileyo ebukhali. I-polyethylene "inamathela" kwimbumbulu ngokunyibilikisa i-polyethylene ngenxa yokungqubana okubangelwa kukujikeleza kwembumbulu. Xa ukujikeleza kuyeka, akukho bushushu buveliswayo, kwaye i-polyethylene iyaphola kwaye iqine kwakhona.
Umgangatho wepleyiti ye-polyethylene PE bulletproof ngokubanzi imalunga ne-1 ukuya kwi-1.5kg, ilula kakhulu kunepleyiti yentsimbi bulletproof kunye nepleyiti ye-ceramic bulletproof. Nangona kunjalo, ngenxa yemida yenkqubo yezinto ezikhoyo, ipleyiti ye-PE ecocekileyo inokufikelela kwinqanaba eliphezulu lokhuseleko lwe-NIJ III, ayikwazi ukuzikhusela kwiimbumbulu ezigqobhoza imipu kunye neembumbulu ezinamandla ngakumbi, kwaye ixabiso eliphezulu le-polyethylene PE, ixabiso layo lidla ngokuba ngama-200% ukuya kuma-300% ngaphezulu kunepleyiti ye-ceramic bulletproof, ayilulo ukhetho olufanelekileyo.
3. Ipleyiti yeseramikhi engangeni zimbumbulu
Izinto ezifakwa kwi-ceramic zingasebenzisa izinto ezahlukeneyo, ezixhaphake kakhulu yi-alumina, i-silicon carbide kunye ne-boron carbide. Ii-ceramics azinazo iimbumbulu ngenxa yokuqina kwazo okuphezulu, amandla, kunye nokungangeni kweekhemikhali kwiindawo ezininzi. Zingcono kunesinyithi kuba izinto zesinyithi ziya kuvelisa ukuguqulwa kweplastiki kwaye zifunxe amandla xa zichasana nempembelelo yentloko yemfazwe, ngelixa i-ceramic ingayi kuvelisa ukuguqulwa kweplastiki kwaye intloko yemfazwe iya kuba buthuntu okanye yaphuke ngenxa yamandla ayo aphezulu kunye neempawu zobulukhuni. I-ceramic engangeni iimbumbulu kunye ne-high strength high modulus fiber composite plate umaleko ongenazimbumbulu, xa i-projectile enesantya esiphezulu kunye ne-ceramic layer ingqubana, ukuqhekeka kwe-ceramic layer okanye ukuqhekeka kunye nendawo yokuchaphazeleka njengesikhungo esijikeleze ukuze sisebenzise uninzi lwamandla omzimba oqingqiweyo, emva koko i-high modulus fiber composite plate ukuze isebenzise amandla aseleyo omzimba oqingqiweyo. Ke ngoko, ukusetyenziswa kwee-ceramics eziphambili kwiinkqubo zezixhobo kunomtsalane kakhulu kwaye kube yisikhuselo esisetyenziswa kakhulu kwizixhobo zomzimba, izithuthi, iinqwelomoya kunye nezinye izixhobo.
Ingxaki yepleyiti yeseramikhi kukuba emva kokuba ibethekile, indawo yokubetheka ayinakuphinda ikhusele imbumbulu. Kodwa ngoku ipleyiti yeseramikhi ilula kwaye inamandla kunangaphambili, abanye abavelisi banokwenza ubunzima bayo busondele kwipleyiti ye-PE, kwaye ngokusebenzisa izixhobo ezahlukeneyo banokuhlangabezana nobunzima, ixabiso kunye nezinye iimfuno.
Ngobukhulu obufanayo obunomgangatho ofanayo wokhuseleko, ipleyiti ye-ceramic engangenisi bullet ilula kunepleyiti yentsimbi engangenisi bullet, kwaye ixabiso liphantsi kunepleyiti ye-polyethylene PE kwaye nobukhulu bunokuba buncinci.
Ngokubanzi, ipleyiti yesinyithi ekhusela iimbumbulu ilula kwaye inexabiso eliphantsi, kodwa ubunzima bukhulu kakhulu, kwaye kulula ukubangela umonakalo wesibini kumsebenzisi; Nangona ipleyiti ye-polyethylene PE ilula, kodwa amandla okukhusela iimbumbulu aphantsi, kwaye ixabiso libiza kakhulu; Ngokuthelekisa, ipleyiti ye-ceramic ekhusela iimbumbulu ayisiyo kuphela umgangatho wokukhanya, ixabiso eliphantsi, kunye nokukwazi ukukhusela iimbumbulu ibalaseleyo; Ukusebenza kwepleyiti ye-silicon carbide ceramic bulletproof kukwipleyiti ye-alumina, lolona khetho lubalaseleyo lwepleyiti ekhusela iimbumbulu.
