Ukusebenza: Ochwepheshe Bemboni Baxwayisa Ngezingozi Zokuphepha Ekukhiqizeni Okungaphansi Kwezinga
Ezweni elibaluleke kakhulu lokuvikelwa kwe-ballistic, inqubo yokubumba yokucindezela kwe-non-metallicizigqoko ze-ballistickuvele njengento ebalulekile ekuvikeleni abasebenzi bezempi, izikhulu zomthetho, kanye nochwepheshe bezokuphepha. Abantu abangaphakathi embonini kanye nentuthuko yakamuva kwezobuchwepheshe baqokomisa ukuthi imikhuba yokubumba engaphansi kwezindinganiso ingalimaza kakhulu ukusebenza kwesigqoko, kuyilapho ukukhiqizwa okunembile kuqinisekisa ukuhambisana nezindinganiso zokuphepha zomhlaba wonke futhi kwandisa amazinga okusinda kwabasebenzisi.
Okungeyona insimbiizigqoko ze-ballistic, manje eseyindinganiso yemboni ngenxa yokuthi ilula futhi ikhululekile kakhulu uma iqhathaniswa nezinye izindlela zensimbi eziphelelwe yisikhathi, ithembele ezintweni ezihlanganisiwe ezithuthukisiwe njenge-aramid (Kevlar), i-polyethylene enesisindo sama-molecule amaningi (UHMWPE), kanye ne-carbon fiber. Lezi zinto zenziwe njengezindwangu ezifakwe kusengaphambili (prepregs) futhi zakhiwe ngokubumba okucindezelwe—inqubo lapho izinga lokushisa, ingcindezi, kanye nomklamo wesikhunta kunquma khona ngqo ubuqotho bomkhiqizo wokugcina. “Isigaba sokubumba yilapho kwakheka khona amakhono okuvikela esigqoko,” kuchaza uDkt. Elena Marquez, uchwepheshe wesayensi yezinto zokwakha e-International Ballistic Protection Association (IBPA). “Ngisho nokungahambisani okuncane ekusabalalisweni kwengcindezi noma ekulawulweni kwezinga lokushisa kungadala ubuthakathaka besakhiwo obuhlulekayo lapho kushayisana.”
Izingozi Zokubumba Okubi
Ukubumba kwe-hydraulic press okuvamile, okusasetshenziswa kakhulu ekukhiqizeni okungabizi kakhulu, kuvame ukuholela ekusetshenzisweni kwengcindezi okungalingani okulinganiselwe eziqondisweni eziqondile. Lokhu kuphazamiseka kubangela ukujiya kwegobolondo lesigqoko esingaguquki, ikakhulukazi engxenyeni engaphambili lapho ukuthambekela okuthambile kuthola amandla amancane okucindezela. Idatha yokuhlola evela ku-IBPA ikhombisa ukuthi izigqoko ezingabunjwanga kahle zivame ukubonisa ukujula kokugoba ngaphambili okungaphezu kwama-30mm uma zibhekene nezimbobo zesibhamu zohlobo lwama-54 (445±10m/s), zehluleka ukuhlangabezana nendinganiso ye-GA 293-2012 yaseShayina ephoqelela ukugoba okuphezulu kwama-30mm emiphumeleni yangaphambili. Ngaphezu kwalokho, ingcindezi engalingani ilimaza izakhiwo zefayibha ezinhlangothini zesigqoko, kunciphisa ukumelana nezingcezu zesivinini esiphezulu—ngamanani e-V50 (isivinini lapho izingcezu ezingama-50% zingena khona) sehla ngaphansi kwama-610m/s adingekayo achazwe ezindinganisweni ze-GJB 5115A-2012.
Ukubumba okungejwayelekile nakho kuholela ekuhlanganisweni okunganele kwe-resin phakathi kwezingqimba zefayibha. “Lapho ama-prepreg engacindezelwa ngokulinganayo, kwakheka ama-air pocket, futhi ukusatshalaliswa kwe-resin kuba okungaguquki,” kuphawula uMark Williams, umqondisi wokukhiqiza kumkhiqizi wegiya elihamba phambili le-ballistic. “Lezi zimbobo zisebenza njengezindawo ezibuthakathaka, zivumela ama-projectile noma ama-shrapnel ukuthi angene esigqokweni noma adlulisele amandla amaningi e-kinetic ekhanda lomuntu ogqokile.” Amaphutha anjalo ahlotshaniswa nokwanda okungu-40% kwezingozi zokulimala kobuchopho ezingozini ezivivinyweni zasensimini, ngokusho kocwaningo lwango-2025 olwanyatheliswa ku-Ordnance Material Science and Engineering.
Ukubumba Okunembile: Indlela Eya Ekuvikelweni Okuphakeme
Intuthuko kwezobuchwepheshe bokucindezela obuyi-isostatic ibhekana nalezi zinselele ngokusebenzisa ingcindezi elinganayo kuzo zonke izinhlangothi, ilandela isimiso sikaPascal.
Amapharamitha abalulekile ekubunjweni okunembile afaka phakathi ukulawulwa kokushisa (170–180℃ kwezinto ezihlanganisiwe ezisekelwe ku-phenolic resin), amazinga okucindezela (7–8kg/cm²), kanye nesikhathi sokuhlala (imizuzu eyi-10–15). Izinhlelo ezizenzakalelayo ziqapha lezi ziguquguquko ngesikhathi sangempela, zivimbela ukushisa ngokweqile okonakalisa imicu ye-UHMWPE (edinga amazinga okushisa angaphansi kuka-130℃) noma ukucindezela okungaphansi okushiya izendlalelo ziboshelwe kalula. Le nqubo ihlanganisa nezindlela zokusika imiphetho, inciphisa umonakalo wangemuva kokubumba imiphetho yemiphetho yemiphetho engafaka amandla esakhiwo engcupheni.
Isimemezelo Semboni Sokwengamela Ikhwalithi
Njengoba isidingo somhlaba wonke sezigqoko ze-ballistic sikhula, izinhlangano ezilawulayo zigcizelela ikhwalithi yokubumba ezinqubweni zokuqinisekisa. I-NIJ (National Institute of Justice) e-US kanye noMnyango Wezokuphepha Komphakathi waseShayina manje idinga abakhiqizi ukuthi bathumele imibhalo yenqubo yokubumba kanye nemiphumela yokuhlolwa komthelela. “Isitifiketi sesigqoko
"I-n ithembeke kuphela njengokungaguquguquki kwayo ekukhiqizeni," kusho uMarquez we-IBPA. "Abathengi kumele baqinisekise ukuthi abakhiqizi basebenzisa ubuchwepheshe bokubumba ngokunemba, hhayi nje ukuthembela ekhwalithini yezinto zokusetshenziswa."
Kubasebenzisi bokugcina, imiphumela icacile: ikhono lesigqoko sokuvikela izimpilo lincike ekuqineni kwenqubo yaso yokubumba. “Lapho izikhulu zigqoka i-isigqoko se-ballistic, bayakwethemba ukuthi kuzosebenza ngaphansi kokucindezeleka okukhulu,” kusho uWilliams. “Lokho kwethemba kwakhelwe esikhumbeni—lapho ubunjiniyela obunembile buguqula khona imicu ehlanganisiwe ibe isivikelo esingenakungeneka.”
Njengoba ubuchwepheshe buqhubeka nokuthuthukisa amasu okubumba, imboni isondela ekuqedeni ukwehluleka okungavinjelwa, iqinisekisa ukuthi labo abasemgqeni ongaphambili banokufinyelela kwemishini ehlangabezana nezindinganiso eziphakeme kakhulu zokuphepha nokusebenza.
