Daim ntawv tiv thaiv kab mob ceramic (phaj tiv thaiv kab mob)yog ib feem tseem ceeb ntawm cov khoom siv tiv thaiv mos txwv. Tam sim no, silicon carbide ceramics thiab high alumina ceramics yog ob qho khoom siv tiv thaiv mos txwv uas xav tau tshaj plaws hauv kev ua lag luam. Vim tias cov txheej txheem tiv thaiv mos txwv tshwm sim hauv lub sijhawm luv luv, cov khoom siv tiv thaiv mos txwv xav tau ntau yam khoom, xws li qhov ceev, porosity, hardness, fracture toughness, elastic modulus, suab nrov thiab lub zog kho tshuab, thiab lwm yam.
Chemshun ceramic alumina ballistic sheet yog ua los ntawm cov hmoov alumina zoo heev ua cov khoom tseem ceeb. Qhov huv ntawm α-Al₂O₃ tshaj 99%, qhov ceev yog ≥3.9g / cm³, qhov porosity ze rau xoom, thiab qhov nqus dej tsis tshaj 0.02%. Qhov nyuaj tuaj yeem ncav cuag siab dua HRA88, uas yog thawj cov khoom siv xaiv rau cov khoom siv tiv thaiv mos txwv. Qib tiv thaiv mos txwv tshaj li American standard theem 3. Tib lub sijhawm, nws kuj ua tau raws li qhov xav tau ntawm cov neeg siv khoom rau silicon carbide bulletproof ceramics. Qhov ceev yog ≥3.1g / cm³, qhov nyuaj yog ≥HRA92, thiab qib tiv thaiv mos txwv tuaj yeem ncav cuag American Standard 4.
Qhov loj ntawm chemshun alumina bulletproof ceramic sheet yog 50 * 50 * 10mm thiab 50 * 25 * 10mm, thiab qhov loj li niaj zaus ntawm silicon carbide ceramic yog 250 * 300mm. Cov neeg siv khoom muaj lwm yam lus qhia thiab tuaj yeem lees txais kev hloov kho.
