Amagwebu esinyithi | I-R&D yeeNkqubo zoKhuseleko lweBalistikhi yeeNkqubo zeMfazwe yanamhlanje

Yintoni imathiriyeli yebhola? Isetyenziswa phi?
Esona sikrweqe sixhaphakileyo siya kusebenzisa iipleyiti ze-ceramic njenge-baffles, kodwa i-ceramic shatters kwimpembelelo kwaye ilahlekelwa amandla ayo okulwa okuzinzile. Uninzi lwesikrweqe sepleyiti yentsimbi sinengxaki efanayo yeembumbulu ezigqabhukileyo xa zichaphazeleka. Ezi ziqwenga zinokubangela ukwenzakala kulowo usinxibileyo isikrweqe. Abanxibi abafaka amabala esibini esikrweqe ebusweni babo banokungakhululeki kwaye bongeze iindleko kumntu, inkampani, okanye urhulumente. Ukuphuhliswa kobuchwephesha bokulwa obulula obufana neenqwelo-moya kunye neenqwelo ze-amphibious, kunye nesidingo sokwandisa ukuhamba kwemikhosi yasemhlabeni, zifuna izinto ze-ballistic eziqhubeka zinciphisa ubunzima bezixhobo ngelixa ziphucula ukusebenza kwe-ballistic.
Izikhuselo zeBallistic ziyafumaneka kwiindidi ezahlukeneyo kunye namabakala. Ezi zixhobo zisetyenziselwa ukukhusela iglasi, izixhobo zemoto, izixhobo zomzimba kunye nezikhuselo. Amaphepha eplastiki alayitiweyo anika uluhlu olubanzi lokhuseleko, ukusuka kwiglasi eqinisekisiweyo etywiniweyo ukuya kwizinto eziphakamileyo zebhola. Izinto zeBallistic zihlala ziqinile, kodwa zinokuthamba. Zinokuba nzima, njenge-Kevlar, i-UHMWPE, i-Lexan okanye i-carbon fiber composites, okanye ilula, njengealuminiyam, intsimbi, i-titanium okanye ezinye ii-alloys.
Ngokuhambela phambili kwetekhnoloji, isikrweqe somzimba we-ballistic sitshintshe kakhulu. Imakethi yehempe yangaphantsi engangenwa bullet ibona uhlaziyo olukhuselekileyo nolula. Oku kuvule ibala elitsha ledabi letekhnoloji ye-Composite Metal Foam (CMF), ukuyikhupha kwindawo yeenkqubo zonyango ukusuka kwiibhumpa zemoto ukuya kukutshintshwa kwamadolo.
Iintsimbi zogwebu ezilodwa okanye ezidityanisiweyo zinoxanduva loku - ezi ngamagwebu olwakhiwo ngendlela yamanqwanqwa esinyithi angenamgongxo, afakwe kwizixhobo ze-ballistic njengesixhobo esingundoqo, kodwa nanjengemiphakathi kwizicelo ezintsonkothileyo ezifana nentsimbi yesikrweqe, iiseramikhi, kunye ne-fiberboard. I-foam ayigcini nje ukumisa impembelelo yesantya esiphezulu seebhulethi kunye neegobolondo, kodwa iphinde iwatyumze ngokupheleleyo. Kwaneembumbulu zokugqobhoza, ezenzelwe ngokukhethekileyo ukukrazula isikrweqe, azikwazi ukungena kuzo.
Kwigorha, isinyithi esinegwebu kwizinto ezisetyenziswayo zokuzikhusela ziquka:

• Injongo ngokuBanzi iiVests ezingenwe ziimbumbulu
• IiVests zeBulletproof ye-Flotation esebenzayo
• IiVesti eziNgangenwa ziimbumbulu ezidadayo
• Iihelmethi ezinobuchule
• I-Ballistic igxalaba kunye neeseti zesikrweqe ezisecaleni
• Ngokhuseleko lwe-visor kunye nomqolo
• Izikhuselo zeBallistic

Kwizixhobo ezixhobileyo ezinzima kunye nezixhobo zokusinda, isinyithi sogwebu sisetyenziselwa iintlobo ngeentlobo zezicelo ezibandakanya:

• Ukwenza izixhobo ezihlanganisiweyo
• Ukwenza iipleyiti zesiseko ezixhathisayo kwizithuthi
• Ukwenza iibhokisi zokulahla umkhosi

Yintoni iMetal Foam? Yintoni i-Foam Metal kwaye zeziphi iimpawu zayo ezimangalisayo?
Isinyithi esinegwebu sisixhobo sesinyithi esinemingxuma esenza i-mesh-dimensional mesh structure kwi-metallic matrix. Ngenxa yokuba kukho iipores ezininziigwebu lesinyithi, ubungakanani, inani, ukufana, ukudibanisa kunye nokutywinwa kwee-pores kuchaphazela iimpawu zayo. Iiparamitha ezihambelana ngokusondeleyo neempawu zesinyithi ze-foam ziquka ubungakanani bepore, i-porosity epheleleyo, i-porosity esebenzayo, ubuninzi kunye nommandla othile womhlaba.
Isinyithi esinegwebu, njengodidi olutsha lwemathiriyeli eneempawu zetsimbi kunye nezinye iimpawu ezikhethekileyo ezibonakalayo zezinto ezingezizo ezentsimbi, ifumana ingqalelo engakumbi nangakumbi. Iimpawu eziphambili zesinyithi se-foam zilandelayo:

• Izinto ezikhanyayo kakhulu (i-75-95% yomthamo iqukethe indawo engenanto)
• I-porosity ephezulu kakhulu
• Amandla acinezelayo aphezulu adityaniswe neempawu ezintle zokufunxa amandla
• I-conductivity ephantsi ye-thermal
• Amandla aphezulu

Umgaqo-siseko wokufunxa amandla kwisinyithi sogwebu
Ukongeza ekusetyenzisweni kwezorhwebo ukuhluza, ukunciphisa ingxolo, ukugquma kunye nabathwali be-catalyst,amagwebu esinyithibangumgqatswa owomeleleyo wesicelo kwiinkqubo zesikrweqe ezihlanganisiweyo kwindawo yokufunxa amandla.
Njengesixhobo sokukhusela i-ballistic, i-foam metal ilula, i-high-high-high-power-foam material eyenziwe kusetyenziswa i-spheres yentsimbi engenanto efakwe kwi-matrix yensimbi eqinileyo. Esi sixhobo sibonise iimpawu ezibalaseleyo zoomatshini xa kuthelekiswa nayo nayiphi na enye imathiriyeli yesinyithi. Ezi mpawu ziphezulu zesinyithi sogwebu zibamba amandla ngokukhawuleza kwiimpembelelo zesantya esiphezulu sebhalistikhi xa kuthelekiswa nokulayisha okulinganayo.
Izixhobo zokufunxa amandla ezifumaneka ngokurhweba, ezidla ngokufunxa amandla e-kinetic ngoomatshini ngokuwacinezela okanye ngokuwaphambukisa kuxinzelelo oluthe gqolo kumgama omde, zisebenza ngokufana nemithombo, kodwa zibuyela umva, zizenze izixhobo zokugcina amandla endaweni yokufunxa amandla.
Ubume be-porous of foams metallic bubanika i-curve ekhethekileyo yoxinzelelo; emva kokuba uxinzelelo olusetyenzisiweyo lugqithise i-plateau ye-extrusion, i-foam iya kuqala ukucinezela ngoxinzelelo oluchanekileyo malunga ne-50-70% yoxinzelelo. Ukongezwa koxinzelelo / ijika loxinzelelo kuchaza indlela yokuziphatha kwe-absorber yamandla efanelekileyo.

Isebenza njani isinyithi sogwebu kwisikrweqe somzimba?
Isinyithi se-foam sibonakaliswe ukuba sibambe iinqununu zembumbulu kwaye ikukhusele kuwo nawuphi na umonakalo wesibini. Uninzi lwesikrweqe somkhosi womkhosi sisebenzisa i-Kevlar-like material as a back layer, edla ngokulinganiswa i-III-A kwaye iya kumisa imijikelo yompu yodwa. Isikrweqe esithambileyo simisa iimbumbulu ngokuchitha amandla, kwaye kuba uninzi lweembumbulu zesandla azibukhali njengeembumbulu zompu, kufuneka nje uzithobe ukuze zingangeni kulusu lwakho. Umaleko wesinyithi esinogwebu sisixhobo sokufunxa isikrweqe somzimba kwiimbumbulu zamandla eziphezulu ezifuna ukuba isikrweqe esiqinileyo siyeke. Ulwakhiwo olwandiswayo lweigwebu lesinyithiUgqithiso lwamandla ongquzulwano ngobuchule obungaphantsi kakhulu kunamalungu aqinileyo. Kwindawo yempembelelo, i-foam ihambelana ngokulula nento echaphazelayo. Le deformation yeplastiki ekuhlaleni ifunxa amandla oomatshini. Kuzo zombini ezi meko, amandla amancinane kakhulu ongquzulwano afunxwa sisiqina. Abanye abantu bakhetha ukongeza umaleko wesithathu emva kwesikrweqe esithambileyo, esibizwa ngokuba yi-trauma pad. Le yiphedi eyenziwe ngezaleko zolwelo olungeyo-Newtonian kunye ne-padding. Ikwanciphisa ngakumbi impembelelo yembumbulu kulowo uyinxibileyo.
