Tsis muaj qhov "zoo tshaj plaws" cov khoom siv lub tsho tiv thaiv mos txwv, tsuas yog kev sib xyaw ua ke zoo tshaj plaws rau kev tiv thaiv tshwj xeeb. High -kev ua tau zoo fibers, ceramics, hlau, thiab cov khoom ntse txhua tus muaj lawv qhov zoo thiab qhov tsis zoo. Niaj hnub nimno tseem ceeb cov tsho tiv thaiv mos txwv siv cov qauv "mos- nyuaj" tsim, ua kom muaj kev tiv thaiv zoo los ntawm kev sib koom ua ke ntawm ntau yam ntaub ntawv.
1. High -kev ua tau zoo fibers (xws li Kevlar, UHMWPE) - Lub teeb yuag thiab hloov tau, haum rau kev tiv thaiv txhua hnub.
Qhov zoo: Lub teeb yuag, hloov tau yooj yim, tuaj yeem ua rau hauv -fitting vests, haum rau hnav ntev, zoo tiv thaiv cov mos txwv phom thiab shrapnel.
Cov ntaub ntawv sawv cev:
Kevlar: Lub zog tensile yog 5 npaug ntawm cov hlau, dav siv hauv tub ceev xwm lub tsho tiv thaiv.
Ultra- siab molecular hnyav polyethylene (UHMWPE): Sib dua thiab muaj zog dua Kevlar, tab sis nrog tsis zoo siab - kub tsis kam.
Cov kev txwv: Tsis tuaj yeem tiv taus siab - cov phom phom nrawm ib leeg.
Yog tias qhov zais cia thiab kev nplij siab yog qhov tseem ceeb ntawm koj, xws li cov tub ceev xwm tub ceev xwm lossis cov neeg saib xyuas kev nyab xeeb, siab - fibers kev ua tau zoo yog qhov kev xaiv zoo tshaj plaws.
2. Cov khoom siv ceramic (xws li silicon carbide thiab alumina) - Kev Tiv Thaiv Hardcore, tshwj xeeb tshaj yog tiv thaiv siab -Speed Bullets
Qhov zoo: Cov hardness siab heev, muaj peev xwm tawg cov mos txwv thaum muaj kev cuam tshuam, cuam tshuam lawv lub zog kinetic; ib qho khoom siv tseem ceeb rau kev tiv thaiv phom phom.
Txoj kev siv: feem ntau yog siv los ua txheej txheej ntawm lub phaj, nrog rau lub phaj fiber ntau rov qab, ua tiav ob lub tshuab ntawm "cov mos txwv fragmentation + lub zog nqus".
Kev txwv: Tsis tuaj yeem tiv taus qhov cuam tshuam rov qab; ua tsis tau zoo ib zaug tawg; kuj brittle thiab susceptible rau kev puas tsuaj los ntawm tee.
Yog tias koj ntsib siab -kev hem thawj rau kev sib ntaus sib tua ib puag ncig, xws li kev sib ntaus sib tua lossis kev tawm tsam- kev ua phem ua phem, cov phaj ceramic yog qhov tseem ceeb.
3. Cov khoom siv hlau (xws li cov hlau tshwj xeeb thiab cov titanium alloys) - Cov khoom muaj zog thiab ruaj khov, tab sis loj heev thiab tsis tu ncua
Qhov zoo: Tus nqi qis, rov siv tau dua, thiab tiv taus ntau dua rau kev cuam tshuam.
Kev txwv: hnyav (ntau dua ob npaug ntawm qhov hnyav ntawm cov phaj ceramic), kev txav tsis zoo, thiab maj mam hloov los ntawm ceramics thiab cov khoom sib xyaw.
Nws tseem muaj cov ntawv thov tsuas yog hauv pob nyiaj- txwv tsis pub lossis tshwj xeeb cov xwm txheej, xws li qee lub foob pob pov tseg lossis cov bunkers ruaj.
4. Composite thiab Smart Materials (piv txwv li, STF, ACF) - Kev taw qhia yav tom ntej, txhim kho kev ua tau zoo tag nrho
Shear Thickening Fluid (STF): Hardens tam sim ntawd thaum muaj kev cuam tshuam, txhim khu kev sib tsoo thiab ballistic tsis kam ntawm fiber ntau txheej, ua tiav "nyias li khaub ncaws, muaj zog li armor."
ACF Artificial Cartilage Material: Nws cov qauv biomimetic tuaj yeem nqus tau ntau dua 90% ntawm lub zog cuam tshuam, txo qhov kev pheej hmoo ntawm kev raug mob hnyav thiab txhim kho kev nplij siab.
Graphene Sponge: Cov khoom siv tshiab nthuav tawm los ntawm CCTV, tsis tshua muaj hnyav thiab hnyav heev, nws xav tias yuav dhau los ua cov tiam tom ntej ntawm ultralight armor muab tub lim.
Cov ntaub ntawv no yog tsav txoj kev loj hlob ntawm cov tsho tiv thaiv mos txwv rau sib dua, ntse dua, thiab ntau yam qauv tsim.
