Letlapa la Ceramic bulletproof (poleiti e thibelang likulo)ke karolo ea bohlokoa ea thepa e thibelang likulo.Hajoale, lirafshoa tsa silicon carbide le lirafshoa tse phahameng tsa alumina ke lisebelisoa tse peli tse batloang ka ho fetesisa tse kentsoeng ke likulo 'marakeng.Hobane ts'ebetso ea bulletproof e etsahala ka nako e khuts'oane haholo, li-ceramics tse thibelang likulo li hloka thepa e eketsehileng, joalo ka density, porosity, hardness, fracture toughness, elastic modulus, lebelo la molumo le matla a mochini, joalo-joalo.
Chemshun ceramic alumina ballistic sheet e entsoe ka phofo e ntle ea alumina e le thepa ea mantlha.Bohloeki ba α-Al₂O₃ bo feta 99%, letsoalo ke ≥3.9g/cm³, porosity e haufi le zero, mme sekhahla sa ho monya metsi ha se fete 0.02%.Ho thatafala ho ka fihla ka holimo ho HRA88, e leng thepa ea pele ea khetho bakeng sa lirafshoa tse sa keneleng likulo.Boemo ba likulo bo feta tekanyo ea Amerika ea 3. Ka nako e ts'oanang, e boetse e finyella litlhoko tsa bareki bakeng sa li-ceramics tsa silicon carbide bulletproof.The density is ≥3.1g/cm³, hardness ke ≥HRA92, 'me kereiti ea bulletproof e ka fihla American Standard 4.
Boholo ba letlapa la chemshun alumina bulletproof ceramic ke 50 * 50 * 10mm le 50 * 25 * 10mm, 'me boholo bo tloaelehileng ba silicon carbide ceramic ke 250 * 300mm.Bareki ba na le litlhaloso tse ling 'me ba ka amohela ho itlhophisa.
