2. Gel ballistic iyo shaybaarrada Kevlar
Sharaxaad ku saabsan sida jel ballistic iyoKevlarmuunado la dhisay ayaa hoos lagu sharaxay.
2.1.Gel ballistic ah
Jeelka ballistic-ga ayaa laga sameeyay jelatin aan dhadhamin.Cufnaanta iyo joogteynta jelku waa inay la mid noqdaan kuwa ay adeegsato Xafiiska Baarista Federaalka (FBI).Si loo gaaro isku waafaqid la mid ah, tilmaamaha lagu bixiyay Ref.[30] waa la raacay waxaana lagu tijaabiyey si waafaqsan heerarka lagu sifeeyey Ref.[31].
8 koob (250 ml) oo ah budada jelatin ee aan dhadhanka lahayn (qiyaastii 1.25 kg) ayaa lagu qasaa 8 l oo biyo ah (1 qayb jelatin 4tii qayboodba oo biyo ah) ilaa ay budada oo dhammi kala diraan.Ka dib markii xalka lagu shubay weelasha (2 × 5 L weelasha ayaa loo isticmaalay isku dhafka kore), 5 dhibcood oo saliid ah (saliid caleen qorfe ah) ayaa lagu shubay xalka oo si tartiib ah u walaaqay.Sababta saliidda lagama maarmaanka ah waa in la oggolaado xumbooyinka xalka si ay u daadiyaan, iyo in la siiyo jel ballistic ah ur wanaagsan.Xalka waxaa lagu dhejiyaa weelasha lagu riday talaajad.Jeelka ballistic-ku wuxuu diyaar u ahaa in la isticmaalo 36 saacadood ka dib markii la sameeyay ka dibna waxaa lagu duudduubay duubka cellophane.Fiidiyow muujinaya faahfaahinta si loo sameeyo jel ballistic ah ayaa laga heli karaahttps://www.youtube.com/watch?v=0nLWqJauFEw.
Cufnaanta jelka ballistic-ga waxaa loo xisaabiyay 996 km/m3(99.6% cufnaanta biyaha).Celceliska cufnaanta dhiigga, baruurta iyo murqaha bini'aadamka32], taas oo ah joogteynta jidhka bini'aadamka, waa 1004 kg / m3.Farqiga 0.8% ee cufnaanta ayaa loo arkaa mid la aqbali karo jel ballistic si uu u soo celiyo hilibka jidhka bini'aadamka.
2.2.Kevlar muunado
Saddex miisaan oo dharka Kevlar ah ayaa loo adeegsaday imtixaannada, kuwaas oo kala ah, 160 GSM, 200 GSM iyo 400 GSM.Maadaama Kevlar loo isticmaali karo sidii wax tolmo leh, xoogga ugu sarreeya ee walaxda waxaa loo isticmaali karaa jihada 0-90.Tijaabooyinku waxa lagu soo ururiyey jihada-45/+45 (quasi-isotropic) jihaynta taas oo nuugta tamar badan marka loo eego saamaynta 0-90 ee midba midka kale33].Tijaabooyinka loo adeegsaday tijaabooyinka waxaa lagu sameeyay dhowr lakab oo 3 ah halkaasoo muunad kasta loo kala dahaadhay sida ay u kala horreeyaan 90/± 45/90.Marka laba ama saddex muunado la is dul saaro, waxa la sameeyay in lakabka ugu dambeeya ee hal muunad la dhigo 45° ilaa lakabka xiga ee muunadda xigta.
Waraaqihii Kevlar waa la kala qaybiyay waxaana loo gooyay xaashiyaha cabbirka A4 si loogu diyaariyo in la isku xidho iyada oo la isticmaalayo resin epoxy-ga iyo qallafsanaanta lagu taliyey.Tijaabooyinku waxay u daayeen inay engegaan.Tijaabooyinku waa la gooyay ka dib markii ay xabagta isku dhejisay oo la isku dhejiyay oo la dhigay meel si loogu sameeyo baaritaanka.

5. Gabagabo
Isbarbardhigga 160 GSM, 200 GSM iyo 400 GSMKevlarsaamaynta ballistic ayaa lagu sameeyay tijaabooyinka ballistic-ga oo lagu sameeyay 9 mm rasaasta Parabellum iyo tiro kala duwan oo lakabyo Kevlar ah.Waxaa la arkay in dhowr lakab oo Kevlar ah aysan wax ku ool u lahayn joojinta madfaca, laakiin waxay ku qasbaan madxafyada inay u sii socdaan gelitaanka ballistic-ga.Kaliya marka tirada lakabyada la kordhiyo, hoos u dhac ku yimaadda gelitaanka mashruuca ee jel ballistic ayaa la arkay.Sababta ugu sarreysa ee dhexgalka, gaar ahaan marka la barbar dhigo madfaca dhibicda godan, waxaa sabab u ah daloolka buuxinaya walxaha Kevlar oo ka dhigaysa inuu u shaqeeyo sidii mashruuc FMJ ah.Celcelis ahaan jaangooyooyin taban oo la mid ah ayaa lagu arkay inta u dhaxaysa FMJ-ga iyo madxafyada dhibicda godan, marka heerka ugu sarreeya la gaaro.
Marka la soo koobo tabarucaadka warqadan, waxaa lagu soo gabagabeyn karaa:
-
1)
-
Waxtarka lakabyada kala duwan ee 160 GSM, 200 GSM iyo 400 GSM ee Kevlar oo lagu dahaadhay jel ballistic ah ayaa la baadhay, waxaana la ogaaday in 200 GSM Kevlar uu waxtar badan u leeyahay joojinta 9mm Parabellum projectile.
-
2)
-
Waxa la ogaaday in aanu jirin xidhiidh toosan oo ka dhexeeya laba nooc oo Kevlar ah oo miisaankoodu kala duwan yahay (sida 200 GSM iyo 400 GSM Kevlar), oo loo dahaadhay si ay u yeeshaan miisaan isku dhafan.
-
3)
-
Afar nooc oo kala duwan oo ah rasaasta Parabellum ee 9mm ayaa la tijaabiyay, iyo guntooda gelinta jel ballistic ayaa loo aqoonsaday lakabyo kala duwan oo Kevlar ah.
-
4)
-
Waxaa la qiimeeyay in 9mm rasaasta Parabellum, oo inta badan laga isticmaalo adduunka, 21 lakab oo 200 GSM Kevlar ah ayaa loo baahan yahay ugu yaraan si loo joojiyo madfaca.Waxaa la soo jeediyay in, taxaddar nabdoon ahaan, arrin nabdoon oo dheeri ah lagu soo daray maadaama dhexgalka uu ku xiran yahay astaanta muuqaalka.
Iyada oo ku saleysan natiijooyinka kor lagu soo bandhigay ee sifooyinka lakabyada Kevlar ee miisaanka kala duwan, waxaa la rajeynayaa in sifooyinkan loo isticmaali karo horumarinta iyo naqshadeynta jaakadaha badbaadada iyo waxtarka leh ee rasaasta.
Isbeddelka guud ee labanlaabaya xaddiga lakabyada Kevlar ayaa loo baahan yahay marka la barbar dhigo tirada dhabta ah ee lakabyada waxyeelloobay, waxay noqon doontaa mid mudan in lagu sahamiyo cilmi-baaris dheeraad ah oo leh rasaas kala duwan.Cilmi-baarista mustaqbalka waxay sidoo kale awood u yeelan doontaa inay muujiso saameynta dhexgalka ay ku leeyihiin majaladaha caliber-ka yar iyo rasaasta Kevlar marka la barbardhigo tan 9 mm Para rasaasta.Sidoo kale, cilmi-baadhista mustaqbalka waxay awood u yeelan doontaa in ay aqoonsato sida rasaasta iyo madfacyada kala duwan ay u galaan 200 GSM Kevlar sida Kevlar-ka loo isticmaalo oo keliya jaakadaha xabadda celiya.Iyada oo sifooyinka lagu arkay madfaca dhibicda godan oo si qoto dheer u gelaya gel ballistic ah, ka dib marka barta godan lagu xannibo Kevlar, cilmi-baaris mustaqbalka ayaa u oggolaan doonta in la aqoonsado haddii saameyn la mid ah ay la kulmi doonto dhacdo halkaas oo madjacadu ay soo gashay dharka, ka hor intaysan gelin hilibka. .
