I ke kaiapuni honua kūikawā o kēia lā, ua mahalo nui ʻia ka papa Bulletproof (a i ʻole nā tile bulletproof) e ka poʻe, akā ma ka mākeke o ka papa bulletproof he nui nā ʻano like ʻole, nui loa ka ʻokoʻa o ka hana, e like me ka mea, ke kaʻina hana a me nā papa bulletproof maʻamau ʻē aʻe hiki ke hoʻokaʻawale ʻia i ʻekolu mau ʻāpana, ʻo ia hoʻi ka papa bulletproof kila, ka papa bulletproof polyethylene PE a me ka papa bulletproof seramika, ʻo nā ʻano papa bulletproof ʻekolu he mau pono a me nā hemahema. Pono pū ka noʻonoʻo piha ʻana i ke koho ʻana. I ke koho ʻana i ka papa bulletproof, pono e kālele i nā ʻano ʻekolu: ke kaumaha, ke kumukūʻai a me ka hiki ke bulletproof (ʻo ia hoʻi ka pae bulletproof), i kēia lā ua hele mai mākou mai kēia mau ʻano ʻekolu o nā ʻano ʻekolu o ka nānā ʻana a me ka hoʻohālikelike ʻana i ka papa bulletproof.
1. Pā kila pale pōkā
Ua hoʻohana ʻia ka papa kila pale pōkā mai ke Kaua Honua II a ua noho aliʻi ma luna o ka mākeke pale pōkā i nā makahiki he ʻumi i hala. Akā ma hope o ka hoʻomohala ʻana o ka papa polyethylene PE pale pōkā a me ka papa seramika pale pōkā, ua hoʻololi mālie ʻia ka papa kila pale pōkā. Hoʻohana mau ʻia lākou i kēia lā, akā i nā helu liʻiliʻi.
Ke hoʻohālikelike ʻia me ka papa pale pōkā hou, maʻalahi ka haki ʻana o ka papa pale pōkā kila ma hope o ka pana ʻia ʻana, kahi e hōʻeha lua ai i ke kino kanaka. Ke hoʻohālikelike ʻia me nā mea ʻelua ʻē aʻe, ʻoi aku ke kaumaha o ka papa pale pōkā kila me ka pae like o ka pale, hoʻopau i ka ikehu hou a hoʻemi i ka maʻalahi o ka mea e ʻaʻahu ana.
ʻOiai ʻo ka papa kila pale kaua ke kumu kūʻai haʻahaʻa loa ma nā mea hoʻokomo ʻekolu, akā ma ke ʻano holoʻokoʻa, ʻaʻole ia e ʻōlelo ʻia ʻo ia ke koho mua.
2. Pā pale pōkā Polyethylene PE
He ʻano mea thermoplastic hou ka Polyethylene PE. Hana ʻia ka papa pale pōkā Polyethylene PE ma ka hoʻopili ʻana i nā olonā polyethylene kaumaha molekala kiʻekiʻe unidirectional ma luna o kahi papa polyethylene kiʻekiʻe. ʻOki ʻia i ke ʻano, waiho ʻia i loko o kahi ʻōmole, a kaomi ʻia ma lalo o ke ana wela a me ke kaomi e loaʻa ai kahi papa pale kaua paʻakikī viscous. "Piʻi" ka polyethylene i ka pōkā ma ka hoʻoheheʻe ʻana i ka polyethylene ma muli o ka friction i hoʻokumu ʻia e ka wili ʻana o ka pōkā. Ke pau ka wili ʻana, ʻaʻohe wela i hana ʻia, a hoʻomaʻalili a paʻakikī hou ka polyethylene.
ʻO ke ʻano o ka papa pale pōkā polyethylene PE ma kahi o 1 a 1.5kg, ʻoi aku ka māmā ma mua o ka papa pale pōkā kila a me ka papa pale pōkā keramika. Eia nō naʻe, ma muli o nā palena o ke kaʻina hana mea o kēia manawa, hiki i ka papa PE maʻemaʻe ke hoʻokō i ka pae palekana kiʻekiʻe loa o NIJ III, ʻaʻole hiki ke pale aku i nā pōkā ʻoki pū a me nā pōkā ikaika aʻe, a me ke kumukūʻai kiʻekiʻe o ka polyethylene PE, ʻo kona kumukūʻai pinepine he 200% a 300% ʻoi aku ke kumukūʻai ma mua o ka papa pale pōkā keramika, ʻaʻole ia he koho maikaʻi.
3. Papa pale pōkā seramika
Hiki i nā mea hoʻokomo keramika ke hoʻohana i nā ʻano mea like ʻole, ʻoi aku ka maʻamau o ka alumina, silicon carbide a me ka boron carbide. He pale pōkā nā keramika ma muli o ko lākou ʻoʻoleʻa kiʻekiʻe, ikaika, a me ka inertness kemika i nā wahi he nui. ʻOi aku ka maikaʻi ma mua o ka metala no ka mea e hana nā mea metala i ka deformation plastic a omo i ka ikehu ke kūʻē i ka hopena o ke poʻo kaua, ʻoiai ʻaʻole e hana ka keramika i ka deformation plastic a e blunt a haki paha ke poʻo kaua ma muli o kona ikaika kiʻekiʻe a me nā ʻano paʻakikī. ʻO ka keramika pale pōkā a me ka ikaika kiʻekiʻe modulus fiber composite plate bulletproof layer, i ka wā e kuʻi ai ka projectile wikiwiki kiʻekiʻe a me ka papa keramika, ka ʻāpana o ka papa keramika a i ʻole ka māwae a i ke kiko hopena e like me ke kikowaena i ka puni e hoʻopau i ka hapa nui o ka ikehu o ke kino projectile, a laila ʻo ka papa modulus fiber composite kiʻekiʻe e hoʻopau hou i ka ikehu koena o ke kino projectile. No laila, ʻo ka hoʻohana ʻana i nā keramika holomua i nā ʻōnaehana pale kaua he mea hoihoi loa ia a ua lilo i pale pale i hoʻohana nui ʻia no nā pale kino, nā kaʻa, nā mokulele a me nā lako ʻē aʻe.
ʻO ka hemahema o ka pā keramika, ma hope o ke kuʻi ʻia ʻana, ʻaʻole hiki i ke kiko hopena ke pale hou i ka pōkā. Akā i kēia manawa ua māmā a ikaika ka pā keramika ma mua o ka wā ma mua, hiki i kekahi mau mea hana ke hoʻokokoke i kona kaumaha i ka pā PE, a ma o ka hoʻohana ʻana i nā mea like ʻole hiki ke hoʻokō i ke kaumaha, ke kumukūʻai a me nā koi ʻē aʻe.
Ma ka nui like me ka pae like o ka palekana, ʻoi aku ka māmā o ka papa bulletproof seramika ma mua o ka papa bulletproof kila, a ʻoi aku ka haʻahaʻa o ke kumukūʻai ma mua o ka papa polyethylene PE a hiki ke lahilahi ka mānoanoa.
Ma keʻano laulā, he maʻalahi a haʻahaʻa ke kumukūʻai o ka papa pale kila, akā nui loa ke kaumaha, a maʻalahi hoʻi e hōʻino lua i ka mea hoʻohana; ʻOiai he māmā ka papa pale polyethylene PE, ʻaʻole maikaʻi ka hiki ke pale i ka pōkā, a he pipiʻi ke kumukūʻai; I ka hoʻohālikelike ʻana, ʻaʻole wale ka maikaʻi o ka papa pale seramika, akā haʻahaʻa ke kumukūʻai, a maikaʻi loa ka hiki ke pale i ka pōkā; ʻOi aku ka hana o ka papa pale seramika silicon carbide ma mua o ka papa alumina, ʻo ia ke koho maikaʻi loa o ka papa pale pōkā.
