Amagwebu Ensimbi | I-R&D Yezinhlelo Zokuvikela I-Ballistic Yezicelo Zempi Yesimanje

Iyini impahla ye-ballistic? Isetshenziswa kuphi?
Izikhali eziqinile ezivame kakhulu zizosebenzisa amapuleti e-ceramic njengama-baffles, kodwa i-ceramic iphahlazeka emthelela futhi ilahlekelwe amandla ayo ukulwa okuqhubekayo. Izikhali eziningi zamapuleti ensimbi zinenkinga efanayo yezinhlamvu eziqhuma lapho zishayisana. Lezi zingcezu zingadala ukulimala kumuntu ogqokile izikhali. Abagqoki abafaka iziqephu zempi zesibili ebusweni babo bangase bangakhululeki futhi bengeze izindleko kumuntu ngamunye, inkampani, noma uhulumeni. Ukuthuthukiswa kobuchwepheshe bokulwa obulula njengezindiza kanye nezimoto ezihamba emanzini, kanye nesidingo sokwandisa ukuhamba kwamabutho angaphansi komhlaba, kudinga izinto ze-ballistic eziqhubeka nokunciphisa isisindo sezikhali ngenkathi kuthuthukiswa ukusebenza kwe-ballistic.
Izihlangu ze-Ballistic zitholakala ngezinhlobo ezahlukene namabanga. Lezi zinto zisetshenziselwa ukuvikela ingilazi, izikhali zemoto, izivikelo zomzimba nezihlangu. Amashidi epulasitiki ane-laminated anikeza ukuvikelwa okubanzi, kusukela engilazini evaliwe eqinisekisiwe kuya ezintweni eziphakeme ze-ballistic. Izinto ze-Ballistic ngokuvamile ziqinile, kodwa zingaba futhi zithambe. Zingaba yinkimbinkimbi, njenge-Kevlar, i-UHMWPE, i-Lexan noma izinhlanganisela ze-carbon fibre, noma zibe lula, njengei-aluminium, insimbi, i-titanium noma amanye ama-alloys.
Ngokuthuthuka kobuchwepheshe, izikhali ze-ballistic body zishintshe kakhulu. Imakethe yehembe langaphansi elingangenwa bullet ibona uguquko oluphephile futhi olulula. Lokhu sekuvule inkundla entsha yobuchwepheshe beComposite Metal Foam (CMF), obukhipha emkhakheni wezinqubo zokwelapha kusukela kobhampa bezimoto kuya ekufakweni kwamadolo.
Izinsimbi zegwebu elilodwa noma eziyinhlanganisela zinesibopho salokhu - lezi zingamagwebu esakhiwo ngendlela yezimbulunga zensimbi ezingenalutho, ezishumekwe kumishini ye-ballistic njengento ewumgogodla, kodwa futhi njengezimaphakathi ezinhlelweni eziyinkimbinkimbi njengensimbi yezikhali, i-ceramics, ne-fiberboard. Igwebu aligcini nje ngokumisa umthelela wesivinini esikhulu sezinhlamvu namagobolondo, kodwa futhi liwachoboza ngokuphelele. Ngisho nezinhlamvu ezibhoboza izikhali, eziklanyelwe ngokukhethekile ukudabula izikhali, azikwazi ukungena kuzo.
Kumaqhawe, insimbi yegwebu ekusetshenzisweni kwemishini yokuzivikela yomuntu siqu ihlanganisa:

• Inhloso Ejwayelekile Ama-Bulletproof Vests
• Ama-Active Flotation Bulletproof Vests
• Ama-Bulletproof Vest Antantayo
• Izigqoko ze-ballistic zamaqhinga
• Ihlombe le-Ballistic namasethi ezivikelo eziseceleni
• Ngokuvikelwa kwe-visor nomgogodla
• Izihlangu zeBallistic

Kumathuluzi ahlomile asindayo kanye namagiya okusinda, insimbi yegwebu isetshenziselwa izinhlelo zokusebenza ezahlukahlukene ezihlanganisa:

• Ukwenza izikhali ezihlanganisiwe
• Ukwenza amapuleti ayisisekelo angazweli ezimotweni
• Ukwenza amabhokisi okuwisa amasosha

Iyini i-Foam Metal? Iyini i-Foam Metal futhi yiziphi izici zayo ezimangalisayo?
Insimbi yegwebu insimbi enezimbotshana eyakha isakhiwo semeshi enezinhlangothi ezintathu ku-metallic matrix. Njengoba kunezimbotshana eziningi ezimbotsheniigwebu lensimbi, ubukhulu, inombolo, ukufana, ukuxhuma kanye nokuvala ama-pores kuthinta izakhiwo zayo. Amapharamitha ahlobene eduze nezakhiwo ze-foam metal ahlanganisa usayizi we-pore, i-porosity ephelele, i-porosity ephumelelayo, ukuminyana kanye nendawo ethile engaphezulu.
Insimbi yegwebu, njengohlobo olusha lwento enazo zombili izakhiwo zensimbi nezinye izici ezikhethekile ezibonakalayo zezinto ezingezona ezensimbi, ithola ukunakwa okwengeziwe. Izici eziyinhloko ze-foam metal zimi kanje:

• Izinto ezikhanyayo kakhulu (75-95% yevolumu iqukethe isikhala esingenalutho)
• I-porosity ephezulu kakhulu
• Amandla acindezelayo aphezulu ahlanganiswe nezinto ezinhle zokumunca amandla
• I-conductivity ephansi yokushisa
• Amandla aphezulu

Umgomo wokumunca amandla wezinsimbi zegwebu
Ngaphezu kokusetshenziswa kwezentengiselwano ukuhlunga, ukunciphisa umsindo, ukufakwa kwe-insulation kanye nokuthwala ama-catalyst,amagwebu ensimbibayikhandidethi eliqinile lokufaka isicelo ezinhlelweni zezikhali eziyinhlanganisela emkhakheni wokumuncwa kwamandla.
Njengesisetshenziswa sokuvikela i-ballistic, insimbi yegwebu iwumkhiqizo onegwebu ongasindi, oqine kakhulu owenziwe kusetshenziswa izimbulunga zensimbi ezingenalutho ezishumekwe ku-matrix yensimbi eqinile. Lesi sici sibonise izakhiwo ezinhle kakhulu zokusebenzisa uma kuqhathaniswa nanoma iyiphi enye into eyinsimbi. Lezi zimfanelo eziphakeme zensimbi yegwebu zibamba amandla ngokushesha emithelela yesivinini se-ballistic ephezulu uma kuqhathaniswa nokulayisha kwe-quasi-static.
Izimunyisi zamandla ezitholakala ngokwentengiso, ezivame ukumunca amandla e-kinetic ngokuwacindezela noma ngokuwaphambukisa ekucindezelekeni okungaguquki ngebanga elide, asebenza ngokufana neziphethu, kodwa abuye ahlehle, awenze amathuluzi okugcina amandla kunokuba abe izinto ezimunca amandla.
Isakhiwo esinezimbotshana zamagwebu ensimbi sibanikeza ijika eliyingqayizivele lokucindezeleka; uma ukucindezeleka okusetshenzisiwe kudlula ithafa le-extrusion, igwebu lizoqala ukucindezela ngokucindezeleka okungaguquki cishe ku-50-70% yobunzima. Ukunwetshwa kwejika lokucindezeleka/ukucindezeleka kuchaza ukuziphatha kwesimunyi samandla esifanele.

Isebenza kanjani insimbi yegwebu esivimbeni somzimba?
Insimbi yegwebu ifakazelwe ukuthi ibamba izingcezu zezinhlamvu futhi ikuvikele kunoma yimuphi umonakalo wesibili. Izikhali eziningi zomzimba wezempi zisebenzisa into efana ne-Kevlar njengesendlalelo sangemuva, esivame ukulinganiswa ngo-III-A futhi sizomisa imizuliswano yesibhamu sodwa. Izikhali ezithambile zimisa izinhlamvu ngokuqeda amandla, futhi njengoba izinhlamvu eziningi zesibhamu zingekho bukhali njengezinhlamvu zesibhamu, udinga nje ukuzinciphisa ukuze zingangeni esikhunjeni sakho. Ungqimba lwensimbi yegwebu luyisithathisi sezikhali zomzimba ukuze kutholakale izinhlamvu zamandla aphezulu ezidinga ukuthi izikhali zempi eziqinile zime. Isakhiwo esikhulayo se-igwebu lensimbiidlulisa amandla okushayisana kancane ngokuyimpumelelo kunezingxenye eziqinile. Endaweni yomthelela, igwebu livumelana kalula nento enomthelela. Lokhu kuguqulwa kwepulasitiki endaweni kudonsa amandla emishini. Kunoma ikuphi, amandla amancane kakhulu okushayisana amuncwa okuqinile. Abanye abantu baphinde bakhethe ukwengeza ungqimba lwesithathu ngemuva kwezikhali ezithambile, ezibizwa nge-trauma pad. Lena iphedi elakhiwe izendlalelo zoketshezi olungeyona i-Newtonian kanye ne-padding. Iphinde yehlise umthelela womthelela wenhlamvu kumuntu ogqokile.
