Kwimekobume yanamhlanje ekhethekileyo yamazwe ngamazwe, ipleyiti yeBulletproof (okanye iithayile zokuthintela iimbumbulu) zixatyiswe kakhulu ngabantu, kodwa kwimarike yepleyiti yokuthintela iimbumbulu zininzi, umahluko wokusebenza mkhulu kakhulu, ngokwezinto, inkqubo kunye nezinye ipleyiti yokuthintela iimbumbulu zinokwahlulwa. kwiindidi ezintathu, ezizezi ipleyiti yentsimbi, ipleyiti ye-PE ye-bulletproof kunye nepleyiti ye-ceramic ye-bulletproof, iintlobo ezintathu zepleyiti yokuthintela iimbumbulu nganye ineengenelo kunye nezinto ezingeloncedo, Ukhetho lukwafuna ingqwalasela ebanzi.Khetha ipleyiti yokukhusela iimbumbulu, kufuneka ugxininise kwiimpawu ezintathu ubunzima, ixabiso kunye nobuchule bokukhusela iimbumbulu (ezizezi inqanaba lembumbulu), namhlanje siphuma kule miba mithathu yeentlobo ezintathu zokuhlalutya ipleyiti yembumbulu kunye nokuthelekisa.
1. Ipleyiti yentsimbi engangenwa bullet
Ipleyiti yentsimbi engangenwa bulletproof ibisetyenziswa ukusukela kwiMfazwe yesibini yeHlabathi kwaye ibilawula kwimakethi yokuthintela iimbumbulu kumashumi eminyaka eyadlulayo.Kodwa emva kokuphuhliswa kwepleyiti ye-polyethylene ye-PE ye-bulletproof kunye ne-ceramic bulletproof plate, ipleyiti yentsimbi ye-bulletproof yatshintshwa ngokuthe ngcembe.Zisasetyenziswa nanamhlanje, kodwa ngamanani amancinci.
Xa kuthelekiswa nepleyiti entsha yokuthintela iimbumbulu, ipleyiti yentsimbi yentsimbi kulula ukuyiqhekeza emva kokudutyulwa, nto leyo eya kubangela umonakalo wesibini kumzimba womntu.Xa kuthelekiswa nezinye izinto ezimbini, ipleyiti yensimbi ye-bulletproof enezinga elifanayo lokukhusela inzima, idla amandla amaninzi kwaye inciphisa ukuguquguquka komntu onxibayo.
Nangona ipleyiti yentsimbi ye-bulletproof iyona xabiso eliphantsi kwizinto ezifakelwayo ezintathu, kodwa ngokubanzi, ayikhuthazwa njengokhetho lokuqala.
2. Polyethylene PE ipleyiti bulletproof
I-Polyethylene PE luhlobo olutsha lwezinto ze-thermoplastic.Ipleyiti yePolyethylene PE bulletproof yenziwe ngokudibanisa i-unidirectional ye-ultra-high molecular weight polyethylene fibers kwibhodi ye-polyethylene ephezulu.Inqunyulwa ibe yimo, ifakwe kwi-mold, kwaye ixinzelelwe phantsi kobushushu obuphezulu kunye noxinzelelo lokufumana ipleyiti yesikrweqe esiqinileyo se-viscous.I-polyethylene "inamathela" kwibhulethi ngokunyibilikisa i-polyethylene ngenxa yokukhuhla okubangelwa ukujikeleza kwebhulethi.Xa ukujikeleza kuyeka, akukho bushushu obuveliswayo, kwaye i-polyethylene iyapholisa kwaye iphinde iqine.
Umgangatho wepleyiti ye-polyethylene PE bulletproof ngokubanzi malunga ne-1 ukuya kwi-1.5kg, ikhaphukhaphu kakhulu kunepleyiti yentsimbi yokuthintela iimbumbulu kunye nepleyiti ye-ceramic ye-bulletproof.Nangona kunjalo, ngenxa yokulinganiselwa kwenkqubo yezinto zangoku, i-PE ecocekileyo inokufikelela kwinqanaba eliphezulu lokukhusela i-NIJ III, ayikwazi ukukhusela kwiimbumbulu zokubhoboza umpu kunye neebhulethi ezinamandla ngakumbi, kunye neendleko eziphezulu ze-polyethylene PE, ixabiso layo lihlala li-200. I-% ukuya kwi-300% ibiza ngaphezulu kunepleyiti ye-ceramic bulletproof, ayilokhetho lulungileyo.
3. Ipleyiti ye-Ceramic bulletproof
Ukufakwa kweCeramic kunokusebenzisa izinto ezahlukeneyo, eziqhelekileyo ziyi-alumina, i-silicon carbide kunye ne-boron carbide.IiCeramics azinambumbulu ngenxa yokuqina kwazo okuphezulu, amandla, kunye nokungangeni kweekhemikhali kwiindawo ezininzi.Kungcono kunentsimbi kuba izinto zetsimbi ziya kuvelisa i-deformation yeplastiki kwaye zifunxe amandla xa zixhathisa impembelelo ye-warhead, ngelixa i-ceramic ayinakukwazi ukuvelisa i-deformation yeplastiki kwaye i-warhead iya kuba buhlungu okanye iphuke ngenxa yamandla ayo aphezulu kunye neempawu zobunzima.I-bulletproof ceramic kunye namandla aphezulu aphezulu imodulus fiber composite plate bulletproof layer, xa iprojectile enesantya esiphezulu kunye nongquzulwano lwe-ceramic layer, i-ceramic layer fragmentation okanye i-crack kunye nendawo yempembelelo njengendawo ejikelezileyo ukuchitha amandla amaninzi e-ceramic. umzimba weprojekithi, emva koko ipleyiti ephezulu ye-modulus fiber composite ukuze iqhubeke isebenzise amandla ashiyekileyo omzimba weprojekthi.Ke ngoko, ukusetyenziswa kweeseramics eziphambili kwiinkqubo zezixhobo zemfazwe kukhangeleka kakhulu kwaye kuye kwaba sisixhobo sokukhusela esisetyenziswa ngokubanzi kwizixhobo zomzimba, izithuthi, iinqwelomoya kunye nezinye izixhobo.
Ukungalungi kweplate ye-ceramic kukuba emva kokubethelwa, indawo yempembelelo ayikwazi ukukhusela i-bullet kwakhona.Kodwa ngoku ipleyiti ye-ceramic ilula kwaye yomelele kunangaphambili, abanye abavelisi banokude benze ubunzima bayo busondele kwipleyiti ye-PE, kwaye ngokusebenzisa izixhobo ezahlukeneyo banokuhlangabezana nobunzima, ixabiso kunye nezinye iimfuno.
Kubukhulu obufanayo kunye nenqanaba elifanayo lokukhusela, ipleyiti ye-ceramic bulletproof ilula kunepleyiti yentsimbi ye-bulletproof, kwaye ixabiso liphantsi kune-polyethylene PE plate kwaye nokuba ubukhulu bunokuba buncinci.
Ngokubanzi, ipleyiti yentsimbi ye-bulletproof ilula kwaye ixabiso eliphantsi, kodwa ubunzima bukhulu kakhulu, kwaye kulula ukubangela umonakalo wesibini kumsebenzisi;Nangona ipleyiti ye-polyethylene PE bulletproof ilula, kodwa isakhono sokuthintela iimbumbulu sihlwempuzekile, kwaye ixabiso liyabiza;Xa sithelekisa, ipleyiti yeceramic yokuthintela iimbumbulu ayipheleli nje ekukhanyeni komgangatho, ixabiso eliphantsi, kunye nobuchule bokuthintela iimbumbulu bugqwesileyo;Ukusebenza kwe-silicon carbide iceramic bulletproof plate ingaphezulu kwipleyiti ye-alumina, lolona khetho lulungileyo lwepleyiti yembumbulu.
