Alumina VS Silicon Ceramic Armor Plate

Pepa pale pōkā poʻokela (pāpale pale pale)he ʻāpana koʻikoʻi o nā lako pale pōkā.I kēia manawa, ʻo ka silicon carbide ceramics a me ka alumina alumina kiʻekiʻe nā mea ʻelua i koi nui ʻia i ka mākeke.Ma muli o ke kaʻina hana pōkā i loko o kahi manawa pōkole loa, pono nā mea ʻoi aku ka nui o nā waiwai, e like me ka density, porosity, hardness, fracture toughness, elastic modulus, sound velocity and mechanical strength, etc.

Hana ʻia ʻo Chemshun ceramic alumina ballistic sheet me ka pauka alumina ultra-fine e like me ka mea nui.ʻOi aku ka maʻemaʻe o ka α-Al₂O₃ ma mua o 99%, ʻo ≥3.9g/cm³ ka nui, kokoke ka porosity i ka ʻole, a ʻaʻole ʻoi aku ka nui o ka hoʻoheheʻe wai ma mua o 0.02%.Hiki i ka paʻakikī ke piʻi ma luna o HRA88, ʻo ia ka mea koho mua no nā seramika pōkā.ʻOi aku ka pae pōkā ma mua o ka pae maʻamau o ʻAmelika 3. I ka manawa like, hoʻokō pū ia i nā pono o nā mea kūʻai aku no ka silicon carbide bulletproof ceramics.ʻO ≥3.1g/cm³ ka nui, ʻo ka paʻakikī ʻo ≥HRA92, a hiki i ka papa pōkā ke hōʻea i ka American Standard 4.

ʻO ka nui o ka chemshun alumina bulletproof ceramic sheet he 50 * 50 * 10mm a me 50 * 25 * 10mm, a ʻo ka nui maʻamau o ka silicon carbide ceramic he 250 * 300mm.Loaʻa i nā mea kūʻai aku nā kikoʻī ʻē aʻe a hiki ke ʻae i ka hana maʻamau.
