Hlau ua npuas ncauj | R & D ntawm Ballistic Protection Systems rau Kev Ua Tsov Rog Niaj Hnub No

Cov khoom siv ballistic yog dab tsi? Nws siv qhov twg?
Cov khoom siv tawv tawv tshaj plaws yuav siv cov phaj ceramic ua baffles, tab sis ceramic shatters ntawm kev cuam tshuam thiab poob nws lub zog rau kev sib ntaus sib tua. Feem ntau cov hlau phaj armor muaj tib qhov teeb meem ntawm cov mos txwv flaking tawm ntawm kev cuam tshuam. Cov tawg no tuaj yeem ua rau raug mob rau tus neeg hnav khaub ncaws. Cov neeg hnav siv cov cuab yeej ua rog thib ob rau lawv lub ntsej muag tuaj yeem tsis xis nyob thiab ntxiv tus nqi rau tus kheej, tuam txhab, lossis tsoomfwv. Txoj kev loj hlob ntawm kev sib ntaus sib tua technologies xws li dav hlau thiab amphibious tsheb, raws li zoo raws li yuav tsum tau ua kom lub zog ntawm lub hauv av rog, yuav tsum tau cov ntaub ntawv ballistic uas txuas ntxiv txo qhov hnyav ntawm armor thaum txhim kho ballistic kev ua tau zoo.
Ballistic shields muaj nyob rau hauv ntau hom thiab qib. Cov ntaub ntawv no yog siv los tiv thaiv iav, tsheb armor, lub cev armor thiab shields. Cov ntawv yas laminated muaj ntau yam kev tiv thaiv, los ntawm cov ntawv pov thawj kaw cov iav mus rau tertiary ballistic cov ntaub ntawv. Cov ntaub ntawv ballistic feem ntau yog nruj, tab sis kuj tuaj yeem muag muag. Lawv tuaj yeem ua haujlwm nyuaj, xws li Kevlar, UHMWPE, Lexan lossis carbon fiber ntau, lossis yooj yim, xws lialuminium, steel, titanium lossis lwm yam alloys.
Nrog rau kev nce qib ntawm thev naus laus zis, ballistic lub cev armor tau hloov pauv radically. Lub khw muag khoom mos mos undershirt yog pom ib lub kiv puag ncig uas muaj kev nyab xeeb dua thiab sib dua. Qhov no tau qhib qhov kev sib ntaus sib tua tshiab rau Composite Metal Foam (CMF) thev naus laus zis, coj nws tawm ntawm thaj chaw ntawm cov txheej txheem kho mob xws li tsheb bumpers mus rau hauv caug hloov.
Ib leeg lossis cov hlau ua npuas dej yog lub luag haujlwm rau qhov no - cov no yog cov qauv ua npuas dej hauv daim ntawv ntawm hollow hlau spheres, uas tau muab tso rau hauv cov khoom siv ballistic ua cov khoom siv tseem ceeb, tab sis kuj yog cov intermediates hauv cov kev siv nyuaj xws li armor steel, ceramics, thiab fiberboard. Ua npuas ncauj tsis tsuas yog nres qhov siab tshaj plaws cuam tshuam ntawm cov mos txwv thiab lub plhaub, tab sis kuj tag nrho crushes. Txawm tias armor-piercing mos txwv, tsim tshwj xeeb los rhuav tshem los ntawm armor, tsis tuaj yeem nkag mus rau lawv.
Rau cov tub rog, ua npuas dej hauv cov khoom siv tiv thaiv tus kheej siv xws li:

• General Purpose Bulletproof Vests
• Active Flotation Bulletproof Vests
• Passive Floating Bulletproof Vests
• Tactical ballistic kaus mom hlau
• Ballistic xub pwg thiab sab tiv thaiv armor
• Nrog visor thiab txha nraub qaum tiv thaiv
• Ballistic shields

Rau cov cuab yeej armored hnyav nrog rau cov cuab yeej ciaj sia, ua npuas ncauj hlau yog siv rau ntau yam kev siv xws li:

• Ua cov cuab yeej sib xyaw
• Ua mine-resistant puag daim hlau rau tsheb
• Ua tub rog poob lub thawv

Foam Metal yog dab tsi? Foam Hlau yog dab tsi thiab nws cov khoom zoo kawg yog dab tsi?
Ua npuas ncauj hlau yog cov khoom siv hlau ntxeem tau uas tsim cov qauv mesh peb sab hauv cov hlau matrix. Vim muaj ntau qhov pores nyob rau hauvhlau ua npuas ncauj, qhov loj, naj npawb, uniformity, kev sib txuas thiab kev sib khi ntawm cov pores cuam tshuam rau nws cov khoom. Cov tsis muaj feem cuam tshuam nrog cov khoom ntawm cov hlau ua npuas dej muaj xws li qhov pore loj, tag nrho cov porosity, zoo porosity, ntom thiab qhov chaw tshwj xeeb.
Ua npuas ncauj hlau, raws li hom tshiab ntawm cov khoom siv nrog ob qho tib si hlau thiab qee qhov tshwj xeeb lub cev ntawm cov ntaub ntawv tsis yog xim hlau, tau txais kev saib xyuas ntau dua. Cov yam ntxwv tseem ceeb ntawm ua npuas ncauj hlau yog raws li nram no:

• Cov khoom siv ultra-teeb (75-95% ntawm qhov ntim muaj qhov tsis muaj qhov chaw)
• Siab porosity heev
• High compressive zog ua ke nrog zoo zog nqus zog
• Tsawg thermal conductivity
• Siab zog

Kev cuam tshuam lub zog nqus txoj cai ntawm cov hlau ua npuas ncauj
Ntxiv rau kev siv hauv kev lag luam rau kev pom, txo suab nrov, rwb thaiv tsev thiab catalyst cab kuj,hlau ua npuas ncaujyog cov neeg sib tw muaj zog rau daim ntawv thov hauv cov cuab yeej sib xyaw ua ke hauv kev ua haujlwm ntawm lub zog nqus.
Raws li cov khoom siv tiv thaiv ballistic, ua npuas ncauj hlau yog lub teeb yuag, muaj zog foamed khoom tsim siv hollow hlau spheres embedded nyob rau hauv cov khoom hlau matrix. Cov khoom siv no tau pom cov khoom zoo heev piv rau lwm yam khoom siv hlau. Cov khoom zoo tshaj plaws ntawm cov hlau ua npuas dej ua rau lub zog nrawm nrawm ntawm qhov siab tshaj tawm qhov cuam tshuam piv rau quasi-static loading.
Kev lag luam muaj zog absorbers, uas feem ntau nqus kinetic mechanical zog los ntawm compressing los yog deflecting nws ntawm ib qho kev ntxhov siab tas li nyob rau hauv qhov ntev, ua haujlwm zoo ib yam li cov springs, tab sis lawv rov qab, ua rau lawv lub zog cia khoom ntau dua li lub zog absorbers.
Cov qauv ntxeem tau ntawm cov hlau nplaum ua rau lawv muaj kev ntxhov siab-txhim kho nkhaus; Thaum cov kev ntxhov siab thov tshaj qhov extrusion toj siab, cov npuas yuav pib compress ntawm ib qho kev nyuaj siab mus txog 50-70% strain. Qhov txuas ntxiv ntawm qhov kev ntxhov siab / txoj kev nkhaus txhais tau tias tus cwj pwm ntawm lub zog zoo tagnrho.

Ua npuas ncauj hlau ua haujlwm li cas ntawm lub cev armor?
Ua npuas ncauj hlau tau raug pov thawj los ntxiab cov mos txwv tawg thiab tiv thaiv koj los ntawm kev puas tsuaj thib ob. Feem ntau cov tub rog lub cev armor siv cov khoom siv Kevlar zoo li cov txheej txheem rov qab, uas feem ntau yog ntsuas III-A thiab yuav tsum tsis txhob muaj phom phom ntawm nws tus kheej. Cov cuab yeej mos mos txwv cov mos txwv los ntawm lub zog dissipating, thiab vim tias feem ntau cov mos txwv phom tsis ntse li cov mos txwv phom, koj tsuas yog yuav tsum tau qeeb lawv kom lawv tsis txhob nkag mus rau koj cov tawv nqaij. Cov npuas hlau txheej yog lub cev armor's shock absorber rau lub zog siab dua cov mos txwv uas yuav tsum tau muaj zog armor kom nres. Lub expanding qauv ntawm lubhlau ua npuas ncaujhloov kev sib tsoo lub zog tsis tshua muaj txiaj ntsig ntau dua li cov khoom siv. Hauv thaj tsam ntawm kev cuam tshuam, cov npuas dej tau yooj yim ua raws li cov khoom cuam tshuam. Qhov no yas deformation hauv zos absorbs mechanical zog. Nyob rau hauv ob qho tib si, tsawg heev ntawm kev sib tsoo zog yog absorbed los ntawm cov khoom. Qee tus neeg kuj xaiv los ntxiv ib txheej thib peb tom qab cov cuab yeej mos mos, uas yog hu ua kev puas tsuaj. Qhov no yog ib lub ncoo ua los ntawm cov khaubncaws sab nraud povtseg ntawm non-Newtonian kua thiab padding. Nws ntxiv txo qhov cuam tshuam ntawm cov mos txwv cuam tshuam rau tus neeg hnav.
