Txij thaum ub los txog niaj hnub nim no, lub hauv paus ntawm txhua yam kev ua tub rog yog nyob ib puag ncig lub hauv paus ntawm "hmuv thiab daim hlau tiv thaiv", uas yog kev tawm tsam thiab kev tiv thaiv. Nrog rau kev nce qib tas mus li ntawm kev siv tshuab tub rog, cov cuab yeej tiv thaiv lub cev mos mos tseem tsis tau ua tiav cov kev xav tau ua haujlwm. Tib neeg pib siv cov ntaub ntawv tawv nrog cov cuab yeej tiv thaiv lub cev mos mos, kom ua tiav qib siab dua ntawm kev tiv thaiv, cov ntaub ntawv feem ntau yog: hlau phaj, titanium alloy, B4C, Si3N4, SiC, Al2O3 thiab lwm yam.
Cov phaj hlau yog thawj zaug siv rau hauv cov khoom siv tawv tawv, txawm hais tias nws txhim kho qib kev tiv thaiv ntawm cov khoom siv mos mos, tab sis lub peev xwm tiv thaiv yog txwv, tsuas yog tuaj yeem tiv thaiv kev tawm tsam ntawm cov mos txwv txhuas thiab cov mos txwv hlau, thiab muaj qhov hnyav ntau dhau yooj yim dhia mos txwv thiab lwm yam tsis zoo.
Cov khoom siv ceramic piv rau cov phaj hlau tau txhim kho ntxiv, qhov hnyav sib dua yog tsawg dua ib nrab ntawm cov phaj hlau, thiab tsis muaj qhov tshwm sim ricochet.
Tam sim no feem ntauphaj ceramic uas tsis muaj zogCov lus qhia: 250 * 300mm cambered sib dhos phaj.
Cov lus qhia dav dav ntawm cov ntawv ceramic bulletproof:
50 * 50 arc nto (370 ~ 400)
Lub dav hlau hexagonal (sab ntev 21 hli)
Ib nrab daim, lub kaum sab xis (25 * 50)
Cov kev cai ua tau zoo ntawm cov khoom siv ceramic uas tsis muaj zog:
Lub hauv paus ntsiab lus ntawm cov khoom siv ceramic thiab hlau tsis sib txawv heev, cov hlau tsis sib tsoo phaj yog los ntawm kev hloov pauv yas kom nqus tau lub zog kinetic ntawm lub mos txwv, thaum cov khoom siv ceramic tsis sib tsoo phaj yog los ntawm nws qhov tawg kom nqus tau lub zog kinetic ntawm lub mos txwv.
Cov khoom siv ua los ntawm cov khoom siv uas tsis muaj pob zeb yuav tsum tau ua haujlwm ntau dua, xws li: qhov ceev, porosity, hardness, fracture toughness, elastic modulus, ceev ntawm lub suab, lub zog kho tshuab, ib qho kev ua tau zoo tsis tuaj yeem muaj kev sib raug zoo ncaj qha thiab txiav txim siab nrog kev ua tau zoo ntawm cov khoom siv uas tsis muaj pob zeb, yog li ntawd, cov txheej txheem tawg yog qhov nyuaj heev, kev tsim tawg yog tshwm sim los ntawm ntau yam, thiab lub sijhawm luv heev.
① Qhov porosity yuav tsum qis li sai tau kom txhim kho qhov nyuaj thiab elastic modulus, qhov nyuaj ntawm ceramic yuav tsum siab dua qhov nyuaj ntawm lub mos txwv.
② Qhov nyuaj ncaj qha txiav txim siab qhov ua tau zoo ntawm cov phaj tiv thaiv mos txwv.
③ Qhov ceev ntawm cov phom tua mos txwv txiav txim siab qhov hnyav ntawm cov phom tiv thaiv mos txwv, vim tias cov tub rog muaj peev xwm txwv tsis pub hnyav, yog li qhov yuav tsum tau ua kom cov cuab yeej ua rog tawv yog qhov sib dua qhov zoo dua.
④Kev faib tawm ntawm cov phaj ceramic bulletproof: 95 alumina ceramic, 97 alumina ceramic, 99 alumina ceramic, thiab lwm yam.
Ntawm cov khoom siv ceramic feem ntau, B4C, Si3N4, SiC kev ua tau zoo tiv thaiv tau zoo heev, tab sis tus nqi siab, Al2O3 muaj tus nqi qis, cov txheej txheem laus, yooj yim tswj qhov loj me, qhov kub sintering qis, yooj yim rau kev tsim khoom loj thiab lwm yam zoo, tau dhau los ua cov khoom siv dav hauv cov khoom siv ceramic tiv thaiv tau.
